More Informations About Car Thieves Hack Keyless Entry

Active 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.

Some Advantages of Car Window Tinting

Although some cars come with the back windows already tinted, most have front windows that are just clear glass. It’s becoming increasingly popular to get the front windows tinted too. There are many reasons tinting is a good idea, and some of them you might not have considered before.

1. Privacy
Privacy is probably the most common reason people decide to get their windows tinted. It can give you peace of mind to know that people can’t look into your car from the outside. They can also protect against theft, since potential thieves won’t be able to see any valuables left inside the car.

2. Less Heat
We’ve all experienced the discomfort of getting into a hot car and having to keep any exposed parts of your body away from scorching metal and plastic. Window tint can help with this, since it can leave your car’s interior up to 60% cooler. This is especially important when you have children in the car.

Window tint also helps you save money and is good for the environment. When the car is cooler, you don’t have to use the air conditioning as much—which means you don’t use as much gas.

3. Protects Your Skin
Unfortunately, frequent drivers are at a higher risk for skin problems due to the UV rays that stream through the window glass. These can even lead to skin cancer if exposure is great enough. Good quality window tint blocks as much as 99% of the UV rays that would otherwise be absorbed by the skin, so it’s are very important if you drive a lot or have children in the car.

4. Keep the Interior of Your Car Looking Great
Those same UV rays that are problematic for your skin can also cause problems for your car’s interior. Leather or cloth upholstery, as well as dashboards and accessories, that are repeatedly exposed to sunlight can start to fade or even crack. Window tinting is a good way to keep your vehicle’s interior looking like new for longer.

5. Safety
Window tinting can even help with safety. The film that’s applied helps to hold windows together and keep small pieces from flying into the interior of the car. In the event of an accident or projectile hitting the window, this can prevent injury to the driver and passengers in a car.

More Informations About Removing Window Tint

Window tint is applied by using a tinting film secured with an adhesive. The adhesive is designed to form a bond that lasts for years, which is a big reason why it’s so important to be careful when applying the film. But sooner or later, the time may come to remove that tint.

When You Need to Remove the Tint
Usually it’s pretty obvious when you need to remove the tint on your car’s windows. If you used a dyed tint film, then the color could fade and start to turn purple. Some films may even start to peel at the edges over time. Finally, the film could be damaged or scratched. While the film does have a protective layer, there are limits to its strength.

Basically: If your window tint starts to look bad, then you should look into removing it.

The other reason you might need to remove your window tinting? Because the law tells you to. Different states, cities, and counties have limits on how much you can tint your windows. If you’re caught with a percentage lower than the legal limit, then you can get a fix-it ticket. And you’ll keep getting fix-it tickets until the tint is removed.

If Your Tint Was Professionally Installed
Many professionals guarantee their tint installation for the life of your car or as long as you own it, especially if you had premium tints installed. So if your tint is faded, peeling, or scratched, then take it back to the shop and you might get it removed or replaced for free. Even if you’re not sure about a warranty or guarantee, you could still get a good price.

If You Installed Your Own Tint
If you installed your own tint, then you’ve got a couple options. You can pay a professional to remove the tint for you. They have the specialized chemicals, tools, and skills to quickly remove even the most stubborn tint.

The other option is to tackle removing the tint on your own. The first step is to weaken the adhesive. This can be done a variety of ways, including ammonia, soap, steam, and heat. The most common method is to use trash bag material cut to fit your window, then to spray the film with ammonia. Cover both sides with the cut-outs, then wait an hour of the ammonia to soak in. Once the adhesive has been weakened, a razor blade or knife can be used to scrape up the edge of the film and peel it back. Like applying the film, this requires a lot of patience and time. You may have to use a razor blade to scrape the film off the window piece by piece. Once the film is removed, use something like Goof Off to get every last bit of adhesive off.

As you can see, this is very complicated and time-consuming, which is why many people think getting it professionally removed is worth the price.

More Informations About Key Systems Make Clean Diesel Possible

There are more than 7 million diesel cars, SUVs, trucks and vans on American roads. Whether you’re in the market for a clean diesel vehicle or you’re simply interested in learning more, it helps to have a basic grasp of three key technologies used to reduce diesel emissions and help new-gen vehicles earn the clean diesel moniker.

Exhaust Gas Recirculation (EGR)
Efficient diesel combustion requires large volumes of air and extreme heat. Unfortunately, these two factors also encourage the formation of nitrogen oxides (NOx), a family of pollutants the EPA now strictly regulates. NOx contaminants contribute to smog, acid rain and ailments such as asthma, bronchitis and emphysema.

To reduce NOx emissions, some clean diesel engines incorporate EGR systems that recirculate into the engine gases from the exhaust. Introducing these gases reduces overall air volume and cools engine temperatures to discourage NOx formation. While this method can be quite effective, its effectiveness can vary based on driving and load conditions, and it can increase by as much as 30% the production of particulates, hydrocarbons and carbon monoxide (CO).

Selective Catalytic Reduction (SCR)
Selective catalytic reduction represents an alternate approach to NOx reduction. As the exhaust stream travels through the SCR system, it passes through a catalytic chamber and is sprayed with a urea-based diesel exhaust fluid (DEF). The ammonia in the fluid reacts with NOx prompting a chemical reaction that converts the harmful pollutant into its base components, nitrogen and water, which can safely be released.

SCR is an effective way to decrease a range of emissions. It reduces NOx by 90%, hydrocarbons and carbon monoxide by 50% to 90%, and particulates by 30% to 50%. The process itself is automatic and requires no driver intervention, but to ensure a continuous supply of diesel exhaust fluid, vehicles are designed with an onboard tank to hold the fluid which must be replenished on a regular basis. To prevent drivers from circumventing the SCR system, some are designed to lock the starting system the next time the car is started if the DEF levels have fallen below an established level.

Diesel Particulate Filter (DPF)
To further reduce emissions, vehicle makers also install a diesel particulate filter in the exhaust pipe to trap soot and particles before the exhaust is released. While many DPFs are classified as self-regenerating, a dirty one can cause engine issues, so the filter should be removed and cleaned every 80,000 to 120,000 miles.

Many clean diesel vehicles rely on some combination of these technologies. Most incorporate EGR or SCR systems, supplemented with diesel particulate filters to further reduce emissions by straining any remaining soot and particles from the exhaust stream.

Some Benefits of Window Tinting

You may have considered getting your car’s windows tinted because you like the increased privacy, or because you want to protect your upholstery from fading. But did you know that window tint can also benefit your health? Here are some ways having good-quality window tint installed can keep you healthy.

Protects Against Skin Cancer
The sun streaming through your car window is made up of ultraviolet rays that can damage skin over time. This can lead to prematurely aged skin, or far worse—skin cancer. Studies have shown that people who drive a lot are more prone to skin cancer and other skin problems on the driver’s side of their body. Dr. Albert Kligman, a professor of dermatology at the University of Pennsylvania Medical School, said this: “Long-time drivers are found to have rougher, more pigmented skin with greater solar damage on their driver’s side.”

The good news is that the film used to tint car windows can reduce these harmful UV rays by up to 99%. This is an important precaution to take, especially if you spend a lot of time on the road.

Other Health Benefits
In addition to protecting your skin, window tint can help keep you comfortable and healthy in other ways, too. Tint can reduce the heat inside your car by as much as 60%. This helps prevent overheating and heatstroke without needing to run your air conditioner as much, which saves gas—and is therefore good for both the environment and your wallet.

The shading that window tint provides is also good for your eye health. You’ll have improved vision and ability to see all around you. This means less eyestrain and eye fatigue when you’re driving in bright sunlight.

Besides the benefits above, window tinting can also help you stay safe in the event of a collision. The tint film is attached to the window with adhesive, and this serves as a bonding agent for the window glass if something causes it to break. The small shards of glass will have more chance of staying together, reducing injury to the driver and passengers. In some cases, the tint film may even provide a barrier that’s enough to keep a person from going through the window.

Tips To Protect Your Car from Sun Damage

Did you know your car’s interior can reach a temperature as high as 140 degrees Fahrenheit on a hot, sunny day? It’s probably no surprise that this amount of heat and the sun’s ultraviolet rays can do a number on your upholstery, dashboard, and other components. Taking steps to protect your vehicle before the damage is done is the smart way to keep the inside of your car looking like new.

Quick Fixes
The cheapest and simplest way to protect your car while you’re not driving it is to set up a sunshade in your windshield when the car is parked. These screens reflect the sun’s rays, which means you’ll come back to a cooler car with an interior that hasn’t been baking while you’ve been gone.

Since a reflective screen isn’t any use while you’re driving, you’ll have to turn to other methods. Seat protectors are a good way to prevent bleaching, fading, and cracking of leather or cloth upholstery. If your seats are leather, use a good-quality leather conditioner frequently—this will also help protect against creasing and cracking.

Another easy way to minimize damage from the sun is to ensure that the surfaces in your car stay clean. Dust, dirt, and other particles can cause scratches, or they can even get baked by the sun into a film that’s extremely difficult to remove. A few minutes with a duster or clean cloth will make a big difference in the long run.

Window Tinting
One of the best things you can do to protect your interior is have your car’s windows tinted. The film that’s applied to the windows can block as much as 99% of harmful UV rays. This isn’t just good for your health, it’s good for the interior of your car, too. You’ll also get additional benefits like reduced glare and less fuel consumption (since your car will be cooler and you won’t have to run the air conditioner as much).

When you take your car in to have the windows tinted, you’ll be able to choose from several different types of tint film. Some are very dark, while others (like the newer crystalline film) are only slightly tinted, so you won’t even be able to tell the film is there while it’s protecting your interior.

Window tinting is especially helpful in regions that get a lot of heat and sunny days, but even people who live in fairly gloomy climates can benefit. Make sure to check the state regulations that apply to window tinting in your area to make sure you’re staying on the right side of the law.
