10 Smart Car Key Programming Related Projects To Expand Your Creativity
Vehicle Smart Key Technology
The smart key technology in vehicles allows a driver to unlock and start the car simply by pressing the door handle or placing the key in the pocket. It also permits a variety of other adjustments, such as seating positions, internal temperature settings, stereo presets, and mirror positioning.
However, it could also create security concerns.
Security
Smart keys are computerized key fobs that communicate with the vehicle through an embedded antenna to unlock doors and activate the motor. Smart key fobs, unlike traditional keys that emit the same frequency each time they're used, transmit encrypted signals that are only compatible with the vehicle to which they belong. This makes it difficult for thieves with a technological edge to fake or intercept the signal and use the key to take your car.
For instance, Mercedes' system -- called Keyless Go -- has an internal transponder that can identify the key of the driver. The Smart Key automatically unlocks and opens the doors and the tailgate when it is within 1.5 meters. It also starts the engine by pressing the key.
Some smart keys, like the ones made by BMW are also equipped with user-specific settings that permit users to alter the mirrors, seat and steering wheel's position and even audio preferences with the push of a button. They also have an emergency lock that keeps the vehicle from starting if the key is not in the ignition.
This technology prevents drivers from accidentally locking their vehicles, particularly when fumbling in a purse or backpack to find keys in a parking lot packed with strangers or on an area with high rates of crime. Many systems also alert drivers when the key is running low on battery, but this feature is dependent on the manufacturer.
Convenience
The smart key is ideal for those on the move and need to get to their destination. By pressing the button on the trunk release or door handle, you can unlock, lock and get into your vehicle. smart car key programming explains that the key fob can also be used to monitor charging, location, and other vehicle information.
It isn't safe to lock your keys inside the car. The key fob connects to an antenna inside the vehicle to determine if it is within range. If it's not, the engine will not start. This will deter thieves from taking your vehicle and then selling parts of it.
BMW reports that the smart key employs rolling codes in order to stop cloning and hacking. A computer inside the vehicle reads the code and verifies it prior to launching the engine. Most systems have a mechanical backup in the form of an unnoticed key blade.
Modern smart keys also know the type of key being used and adjust the car settings accordingly, notes How Stuff Works Electronics. For example, if you start the car while holding the key fob in the palm of your hand, the windows and sunroof open to let air circulate through the cabin. You can also set an upper limit on speed that will only be applied when the vehicle is started using the selected key, which could be useful if you loan your vehicle to a novice driver.
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 activate it, press and hold the lock button while pressing the unlock button.
This will stop your smart key fob from being able to transmit or receive radio waves. This will dramatically extend its battery life. You can always reactivate this function by pressing the unlock and lock buttons once more.
Certain smart keys have anti-theft capabilities that prevent them from being copied by thieves. Mercedes-Benz smart keys use rolling codes to prevent unauthorised access. The computer in the car checks the code milliseconds after the smart key is placed. BMW makes use of a Display Key that has a small LCD color screen. This allows drivers to lock their cars, unlock them, and start them without having to remove the smart key from their pocket.

Special Cases
Smart keys aren't 100% safe from theft, but they can assist in preventing thieves. Smart keys employ rolling security codes to prevent theft, and when placed in the ignition, the car's computer validates the code within milliseconds. Mercedes-Benz developed this technology, which is currently used by luxury car manufacturers.
A smart key system will work even if you forget the key in the trunk or leave it in an establishment. Certain systems will also inform the driver if the battery is running low. Certain brands have key covers specifically designed for smart keys to protect the fob from damage.
