Vehicle Smart Key Technology

smart car key recoding keys for vehicles allow drivers to open and start the car by grabbing the door handle or placing the key in the pocket. It also allows for many other adjustments such as seat position, internal temperature settings and mirror positioning.

However, it could also lead to security concerns.

Security

smart roadster key programming keys are advanced electronic keys that communicate with vehicles via one of the antennas built into the car to open doors and start the engine. Smart key fobs, unlike conventional keys that emit the same frequency every time they're pressed, send encrypted signals that are compatible with the car to which they belong to. This makes it much more difficult for thieves with the latest technology to impersonate or intercept the signal and use the key to steal your car.

For instance, Mercedes' system -- called Keyless Go -- has an internal transponder that can identify the driver's key. The Smart Key automatically unlocks and opens the doors and tailgate when it is within 1.5 meters. It also starts the engine by pressing the key.

Some smart keys, such as the ones made by BMW and Mercedes-Benz, also come with user-specific settings, which allow the driver to alter the mirrors, seat, steering wheel position, and even audio preferences with the push of a button. They also come with a backup lock that prevents the vehicle from starting if it is not connected to the key.

This technology protects drivers from being unable to lock their vehicle, especially when searching in backpacks or purses for keys on a parking lot with strangers or a busy street where crime is high. Many systems also alert drivers when the key is low on battery, although this feature varies by manufacturer.

Convenience

Popular Mechanics explains that the key fob can also be used to monitor charging location, charging status, and other vehicle information.

The main benefit is that you won't accidentally get locked out. The key fob communicates to an antenna in the vehicle to determine whether it's within range. If it's not, the engine won't start. This can deter thieves who could steal your vehicle in order to sell its parts.

The smart key uses rolling codes to ward off hacking attempts as well as cloning, according BMW. The computer in the vehicle recognizes and verifies the code prior to starting the motor. Many systems also have a backup mechanical system that is the key blade, which is hidden for styling purposes.

Modern smart keys also recognize which key is in use and adjust the vehicle settings accordingly, notes How Stuff Works Electronics. For instance, if start the car while holding the key fob in your hand, the windows and sunroof will open to let the air in the cabin breathe. You can also set a speed limit that will only be activated when the car is powered by the selected key. This feature can be useful when you lend your vehicle to a person who is not experienced.

Battery Life

If you're looking for a way to get more mileage out of your vehicle's smart key, or just want to make sure it won't die during a trip to the grocery store, you can activate an auto manufacturer-specific feature called Power Saving Mode. To do this make sure you press and hold the lock button while pressing the unlock button.

This will block your smart key fob from having to send or receive any radio waves. This will significantly increase its battery life. You can reactivate this function by pressing the unlock and lock buttons again.

Some smart keys also have anti-theft features to prevent them from being copied by thieves. For example, Mercedes-Benz smart keys use rolling codes to stop unauthorized access to vehicles. The computer in the car checks the code milliseconds after the smart key is put in. BMW uses a similar method with its Display Key, which includes an LCD touchscreen on the smart Car key programming key for ease of use and allows drivers to lock or unlock their vehicles without ever taking it from their pockets.
