Can Car Thieves Hack Keyless Entry

Keyless EntryActive keyless entry, where a button has to be pushed, has been around for decades. Passive keyless entry, where you don’t have to push a button to unlock the car, is becoming standard on many higher model cars. Both keyless entry methods are much more convenient for drivers. With embedded chips, they also offer more security than traditional keys, since the chip signature has to be present to start the car.

But that doesn’t mean that they’re entirely secure. There have been many publicized break-ins that seem like they’re being done using keyless entry systems. Here are a few of the possible methods that are being suggested.

Passive Signal Amplification

With passive keyless entry, the car emits a low frequency signal that extends a very short distance from the car. When the key comes in range the signal is detected, and the key sends the authorization code to allow the doors to be unlocked.

Security specialists say that thieves may use a device that amplifies that low frequency signal, allowing the car and the key to connect from much farther away. For example, the key could be inside the house while the car is on the street and thieves could amplify its signal to unlock the car door. Analysts say this method could be prevented by installing a proximity chip in the key.

Brute Force Hacks

There are trillions of combinations for the codes between the car and the key, and only a few are valid at any given time. That being said, there are hundreds of codes being transmitted through the air from other keyless entry devices. Computer networks might lock out the account after a few tries, but cars have to ignore these wrong codes, otherwise they’d be locked out all the time.

That lack of functionality is what brute force hacks utilize. They’ll send out transmissions with millions of different code combinations in a matter of minutes. If the right one hits the car, then the doors will unlock. This method is largely combated by increasing the encryption level. Many cars use 56-bit encryption, but upgrading to 128-bit encryption would require so many combinations that brute force would take too long.

Non-Hack Workarounds

There are a few methods that aren’t hacks, just clever tricks. One of these is to use a frequency jammer. These illegal devices can block any transmission within a certain frequency range. Fire one up near a car, and it can stop the signal getting through. The driver will think they locked the car, but it didn’t go through and the car stays unlocked, just waiting for the thief to open the door.

Another method is good old fashioned organized crime: the thieves simply clone the keys and their security programming when the car goes in for repair. You can avoid this by making sure you go to reputable and trustworthy auto repair shops.

So Is Hacking Possible?

The definitive answer from the experts? Yes, it is possible. That being said, it’s not very likely. The cases that have been highlighted by the media are rare, and the methods require a combination of specialized equipment and knowledge. And most importantly, whenever a new weak point is discovered, automakers work quickly to repair it. So make sure that you keep on top of any recalls for your vehicle, since some of them may cover your keyless entry software.

And the absolute best thing you can do to keep your car secure? Most of these robberies happen at night, so make sure that your car is physically removed from harm in a garage or other secure area.

Increase a Car Engine’s Tips

Increase a Car Engine'sWe are all familiar with the term “engine”, and for most of us, it is a complex design of metal and wires engineered to run our car. A good engine is essential for the smooth functioning of a car. An engine converts the gasoline into motion and speed, which a car moves with. An engine’s horsepower (Hp), is the measurement of several non-SI (International System of Units) units of power. In the most basic term, it just means the rate of power, at which work done.

Increasing a Car Engine’s Horsepower

Most cars come with engine horsepower specifications, but one can increase it to suit personal requirements using a few tips given below:

-Change in the Computer Chip:
One can change the ROM chip in the engine control unit (ECU) to increase its horsepower. But in most cases, this will only work along with other modifications in air intake, header, and exhaust systems.
-Free Flow Exhaust:
Installing high-performance exhaust systems will help increase the engine’s horsepower. The advanced exhaust systems use big tail pipes, headers, and free flow mufflers to decrease the air resistance (back-pressure) and enable the exhaust to escape faster.
-Install Turbocharger:
While adding a turbo or supercharger in your car, keep in mind to add a bigger sized cylinder to increase its displacement. Turbo chargers compress the incoming air to effectively increase the amount of air in the cylinder, which adds more oxygen to the combustion process. More oxygen means more power to your engine’s horsepower.
-Cool the Incoming Air:
Compressing air raises its temperature expanding it, whereas cooling will contract it. One can add more cooled air in the cylinder than hot air. Installing an intercooler, which is a type of radiator, with turbocharger will add more horsepower to the car. The air compressed by the turbocharger passes through the intercooler, cooling it before entering the cylinder.
-Reduce Car Weight:
Load beyond a vehicle’s capacity will slow it down. So, lighter the vehicle, more the horsepower of its engine. The weight of the car affects the piston’s function. Each time a piston changes direction, it uses the transfer force from expanding gas in the cylinder to the crankshaft. So, lighter the car, lesser the time and transfer force be taken by the piston to change direction. However, decreasing the car’s weight doesn’t mean removing its parts, just replacing some components with lighter materials. Also, clearing your back seat or trunk would definitely work.
-Air Filter:
An air filter helps to remove solid particles, like as dust, pollen, etc., from air before it enters the cylinder. An increase in the size of the air filter allows more air to enter the engine. More air enables the piston to function efficiently and increases the engine’s horsepower.
-Spark Plugs and Power Fuel:
High performance Iridium spark plugs will make the car run faster by efficiently burning the fuel injected into the engine. Regular cleaning will also increase its productivity. Unleaded fuel causes more harm to the various components of the engine. To enhance its functionality and horsepower, high octane gasoline should be used.

There is no substitute for regular maintenance. Done on time and by a qualified mechanic, maintenance will add more life to the car’s engine. It is important to bear in mind that better horsepower relates to more speed, which needs good brakes. While adding modifications to the car’s engine and other parts, one must also increase the wheel dimensions to add larger brake disc.

A Basic Guide to the Computer in Your Car

Computer in Your CarDid you know that modern cars can have over 80 different computers scattered around the car? These control everything from your automatic windows to your stereo to the brake system to your engine. The computers are all hidden behind body panels, in the engine compartment, and dozens of other places. In fact, the only sign of computers most drivers will ever see is the console interface.

Emissions Standards:  The Birth of Car Microprocessors

Car computers really got their start with the introduction of the catalytic convertor and electronic fuel injector. Before these systems, the fuel/air ratio was controlled by the carburetor, which could be more than a little imprecise. A catalytic convertor requires a precise fuel/air ratio (1:14.7) in order to be effective in eliminating emissions. As emission standards got more and more strict, more control was needed.

Enter the first car microprocessors. The chips were nowhere near as powerful as the ones in personal computer, but they didn’t have to be. After all, they have to process a lot less data and programs. These chips made it possible for the fuel/air mixture to be constantly monitored and adjusted to make sure it had the right ratio. As technology got more advanced, the uses for auto computers multiplied.


As more and more computers were added to cars, something had to be added to tie them all together. This is where the Controller Area Network, or CAN, comes in. The CAN creates a complex network that connects all of the computers throughout the car. The modern CAN design doesn’t even have a central hub or router. All of the individual Electronic Control Units (ECUs) are linked to the network, allowing them to interact seamlessly.

Parts of an ECU

That network would be nothing without the ECUs. These are the actual workhorses of your car’s computer system. On the outside they tend to look like boxes, but inside the housing is a circuitboard with several different components, including:

Analog-Digital Converters:

Many of the sensors throughout the car are analog, but the chip can only deal with digital data. The converters turn those analog signals into 1’s and 0’s so the chip can use them.

High-Level Digital Outputs:

That digital signal hits the processor, which runs it through programming. Depending on how the programming reacts, the chip will send signals through the outputs to operate things like fuel injector, spark plugs, and more.

Digital to Analog Converters:

Like the sensors, most of the parts in a car are mechanical, meaning they need analog signals to run. The convertors take the digital signal and make it into the voltage that’s needed to power the mechanical parts.

Signal Conditioners:

Sometimes that voltage needs to be adjusted to work with certain parts. These conditioners are circuits that make any necessary voltage changes, and are the last link in the ECU chain.

Diagnostic Ports

There are various ports built into the ECUs and the CAN that allow access to the system. Mechanics will use these to connect diagnostic computers to aid them in finding problems with the engine. They also make it easy to switch out faulty ECUs or parts of the CAN without a lot of network splicing.

But they have another common use. Mechanics and car owners can use these diagnostic ports to connect to the engine control module. That connection can then be used to remap the computer, add performance chips, or tune the software.

Find An Easier Way To Obtain A Vehicle

Those who must purchase a new vehicle could be concerned with obtaining car loans in Singapore. They may not have a suitable credit history in order to receive a loan or they might wish to stay away from the interest costs that accompany having a loan. No matter their reasoning, there are actually methods to obtain a motor vehicle that do not include borrowing money.

An individual who really wants to buy a used car may possibly check out sites that provide a number of used vehicles from the vendor. These types of web sites permit an individual to go shopping based on what they are trying to find or their spending budget and also make it easy for them to be able to look through each of the used vehicles to find the one which fits their requirements. These web pages will frequently examine the vehicles and ensure the rates are usually comparable to comparable automobiles so the person will not have to stress about trying to talk the owner down to a reduce quantity. They might be furthermore priced low enough they could be obtained with cash as opposed to the person needing to acquire a loan.

In case you are searching for a whole new car or truck and you don’t wish to obtain a loan, go ahead and look into now. They have a significant selection of autos available sold by the vendor so that you can come across exactly what you might be looking for as soon as possible.


Whether it is the EXP 10 Speed 6, the new Continental GT or the SUV that you favour most, one thing is certain: Stefan Sielaff, the man in charge of Bentley design, promises to make it his business to ensure that Bentley features very strongly as far as luxury design is concerned. If you are thinking, ‘maybe i’ll sell my car and upgrade’, what better manufacturer to consider in your shortlist.


Not all designers and manufacturers understand the concept of fusion when it comes to such crucial aspects as performance and luxury, a concept which Bentley wants to take to a new level. Sielaff specifically mentions the Mulsanne which will become even more luxurious, with greater emphasis on performance for the EXP 10 Speed 6. Of course all models will be instantly recognisable as Bentley, with some unique features to promote individuality. Although no firm decision has been taken yet to come up with another SUV or to produce another sports car like the EXP 10 Speed 6, plans are well under way to ensure the mix of luxury, style and performance when the next Continental GT launches.


Bentley has always been admired for its attention to detail and subtle style. New models will certainly not sacrifice the luxury associated with the brand – on the contrary. Crafted interiors with a definite emphasis on timelessness will be, as has become customary with the Bentley name, a strong design aspect according to the designers. 3D printing will be used to come up with special features to include indicator stalks in the Speed 6. According to Sielaff these can neither be milled nor cast. This certainly will contribute to Bentley’s unique aspects. Further expect quilted wood and stone veneer to be present.


Future generations of Bentley will, according to the designer, feature a long bonnet and short boot, a deep body and sharp lines.


  • For luxury models – expect the lights to be rather large with lower-set smaller lights which will add to the Bentley luxury style’s impression of being relaxed and understated. They will also be different from the performance models insofar as making more upright designs a greater feature.
  • The sportier models – the design will definitely show a move towards a ‘strong, even mean’ look as evidenced by the large headlights, with high-set smaller lights immediately flanking these.


Always instantly recognisable, the two Bentley badge versions will also undergo some redesigning, no doubt keeping in mind what works for the brand: its history as stylish and classy vehicle of choice for those who can afford it, those who set store by its trusted name and image.

Audi maintains its superlative performance in the niche automobile segment with pure class

It seems the era of crossover car models is finally amongst us. With increasing competition in all segments from a huge range of brands, carmakers are looking to carve a niche for themselves and are not afraid to experiment. And it’s only natural for German manufacturers to take an edge in automobile innovation. So the 2017 Audi Q2 is set to send a few jitters down the spines of manufacturers in the luxury crossover segment.

The design of the Q2 is signature Audi design with its lightweight five-door crossover that falls in line with the pattern of the company’s recent range. The edgy design is quite similar to the A3, A4 and A6 models. The design could be divide the opinion of critics but it is obviously worth noticing.

But it’s the performance the car offers that everyone really cares about. So, here it goes. The gasoline-fueled engines first. The smallest is a 1.0 L three-cylinder TFSI engine with air-intake turbochargers with a 116 horsepower output. As expected, it’s the most economical, but the weakest performer. Then come the 1.4 L four-cylinder and the 2.0 L four-cylinder, of which the 2.0 L boasts of an output of 190 horsepower, which puts its performance way above the average mark. The diesels start out with two models but Audi offers three different tunings on these two models. While the 1.6 L TDI engine comes with 116 horsepower, matching the 1.0 L gasoline, the 2.0 L TDI comes with an output of 150 or 190 horsepower.  The car also comes with new transmissions that Audi came up with for the 2.0 L gas and diesel engines. The car is not particularly suited as a sports car but still gives four modes of operation which are Auto, Comfort, Dynamic and Pedal Response for the kind of ride you’re enjoying or want to enjoy. Audi also took care of off-roading with 7.9 inches of ground clearance.

The interior is typically Audi. Nothing flashy but just built for comfort so you don’t mind driving miles inside it. The chrome touches add a little flash to the interior and the switches are easy to reach for any driver. The ergonomics of the car is also near perfect. The infotainment system is a real screamer though, with 705 watts Bang & Olufsen 14-speaker sound system that is a treat for audiophiles. The interior lighting has a soft white glow as well thanks to LED lighting. In general, the Q2 beats most luxury limos and sedans in the infotainment and car ambience part.

The safety system is great as well with great technology like Lane Assist and Stop and Go Cruise Control. The car also comes fitted with a pre-sense early warning system. The price predictions top out at $25,000 to $28,000 for the base model so it’s time to start saving up if you want to buy this car come 2017 when it releases in Europe. Overall the car is just great product innovation and a real winner for buyers in the luxury crossover segment. German innovation does it again.

Window Tinting Do It Yourself or Hire a Professional

Thinking of tinting the windows on your car? Like any other car customization, tinting can either be done at home or by a professional. And like any other customization, it’s easy to get a wide variety of advice from friends and on forums.

Here’s a quick look at the two different options to help you make your decision.

The Do It Yourself Experience

The most common reason to tint your windows yourself? Cost. Even the more expensive pre-cut film packages are usually still a couple hundred dollars cheaper than a professional installation. That being said, there’s no room for error. If you don’t install the tint correctly, getting it removed is extremely difficult, so here are some things to consider:

  • Make sure your windows are completely spotless. Anything that’s on there when you apply tint will stay there for the life of the tint.
  • Be very, very patient, especially on curved glass. It’s really easy to get bubbles and stripes, and it can peel if you don’t apply it perfectly.
  • Look into pre-cut films. Available for many popular cars, these have tint sheets pre-cut to fit the windows. They cost more than cutting it yourself, but they tend to give you better results.
  • Brand matters, so does your research. The roll of $15 tint might seem like a steal, but odds are good it’s going to turn purple on you. The better the brand and higher the quality, the longer the tint will last.
  • Check local tinting regulations. Different states, counties, and cities will allow different levels of tint on your windows. Make sure that you know the law before you start tinting yours.
  • It can be very frustrating. The tint film is very fiddly, and a crease in the wrong place has made plenty of people throw their tint across the room.

Expect your DIY tinting project to last anywhere from a couple hours to a whole afternoon. While it can be tricky, if you can pull off a pro-looking job, then you’ll get the dual satisfaction of a job well done and having saved a good chunk of money.

What to Expect From a Pro

Like anything else, you’re simply going to have an easier time when you go to a pro. You drop off your car, hang out, and then you’ve got tinted windows. It usually takes less than an hour for a standard car. Of course, that convenience does come with a higher price tag.

  • Expect to pay anywhere from $150-$400+. The cost depends on where you live, the size of the windows, then number of them, and the quality of the tint you want. There have been $100 specials for lower quality tints in some areas, while a high quality tint on a large van can cost quite a lot.
  • The pros have the right tools and the right chemicals. The pros have the right gear to custom fit the tint perfectly to your windows. They also have the right chemicals to make your window spotless and remove the tint if things go wrong.
  • Pros often go the extra mile. It’s not uncommon for pros to do things like take the door panel off to extend the tint below the window line.
  • You’ll usually get a guarantee. Depending on the tint, these can be anywhere from a few years to the life of the car. If nothing else, pros will reapply the tint if there are flaws or problems.
  • Pros keep on top of tinting regulations. It might seem silly, but tinting regulations do change, and professional tinters make sure to know all applicable tinting level codes to make sure you won’t get a ticket.

Most people choose to use a professional to avoid the hassle and get the guarantee on the work. While it may cost more, it also means less stress and more time spent doing what you want instead of swearing at the window tint.

Guide to Window Tint Percentages

Planning to have your car windows tinted? One of the first things you’ll have to decide is how dark you want the tint to be. Even a slight amount of tint can reduce glare and make it easier to see in bright conditions. The degree of tint is expressed in a percentage, so it’s important to understand what this means before you make any decisions.

What the Numbers Mean

The percentage that you’ll see is a measure of the visual light transmission of the window film, or VLT. A 30% window tint allows 30% of the light to go through, and it blocks the other 70%. It’s important to note that a lower percentage means less light is allowed to go through, so the lower numbers mean darker when you’re talking about window tint percentages.

Because a good portion of the heat we get from the sun comes from visible light, a lower percentage also means that the window film will keep your car cooler, since it’s blocking more light.

What’s Allowed By Law?

It’s important to know that most states have legal limits on how dark you can tint your car windows. These vary widely, with some states having limits as low as 20% and some as high as 70%. A handful of states don’t allow any aftermarket tint at all, just the tint from the factory.

It matters whether you’re talking about the front windows/windshield or the back windows, too. Many states allow darker tint on the back windows where visibility isn’t as much of an issue.

When you look at a list of allowable tint percentages (like the one on this page), you’ll notice that many of the states that allow darker tint (lower percentages) are in the southern US. This is because tint is much more important for comfort and safety in sunny, hot areas. There are exceptions, however—California only allows a 70% tint, for example, while rainy Washington state allows 24%.

Factors to Consider

Once you make sure you’re in compliance with the laws of your state, you can decide how much tint you’d like. If you have a lot of problems with glare and eyestrain, or if you just like the look of dark windows, you’ll probably want to go for a lower percentage.

Age can be a factor, too. Older drivers often find that it’s more difficult to see through darker film, especially at night. This is also true for people who have less than perfect eyesight. The dividing line is generally about 35% tint. This level or lower is okay for younger drivers, but older ones may want to stay in the 50% range.

If you have children who ride in the backseat a lot, consider a darker tint on the back windows. This will help keep them cooler and prevent the sun shining in their eyes as much.
