Vehicle Smart Key Technology

The smart key technology in vehicles enables drivers to unlock and start their vehicle by simply touching the door handle, or by putting the key into the pocket. It also enables a range of other adjustments, such as the position of seats as well as internal temperature settings mirror positioning and stereo presets.

However, this can also lead to security concerns.

Security

Smart keys are sophisticated electronic keys that communicate with the vehicle using one of the antennas that are embedded in the vehicle to unlock doors and begin the engine. Smart key fobs, as opposed to conventional keys that emit the same frequency each time they're pressed, transmit encrypted signals that are only compatible with the particular car to which they belong to. This makes it difficult for hackers with the latest technology to intercept or fake the signal, and then use your key to steal your vehicle.

Mercedes' Keyless Go system For instance, it has an internal transponder which identifies the key of the driver. When smart car key repair comes within 1.5 meters of a car it will automatically unlock the tailgate and door and the engine will start when the key's button is pressed.

Furthermore there are smart keys thatlike those made by BMW -- have individual user settings that let the driver adjust seat, mirrors and the steering wheel's position as well as audio preferences with the click of a button. They also have an emergency lock that keeps the vehicle from starting without the key in the ignition.

This technology helps drivers avoid accidentally locking their vehicles and causing damage to their vehicle, particularly when searching backpacks or purses for keys on an open parking lot with strangers or on a busy street where crime is high. Many systems also alert motorists when their keys are in danger of being depleted, though this feature varies by manufacturer.

Convenience

If you're in a hurry to get somewhere the smart key makes entering your vehicle as easy as possible. You can unlock, lock and start your car by pressing the door handle or the trunk release. Popular Mechanics explains that the key fob can also be used for tracking charging location, charging status, and other information about your vehicle.

A big benefit is that you can't accidentally lose your keys. The key fob communicates with an antenna inside the vehicle to determine whether it's in range. If it's not in range, the engine will not start. This will deter thieves from absconding with your vehicle and selling parts of it.

BMW reports that the smart key uses rolling codes as well to stop cloning and hacking. The vehicle's computer can recognize and verify the code prior the start of the motor. Many systems also have a mechanical backup in the form of the key blade, which is hidden for styling purposes.

How Stuff Works Electronics notes that modern smart keys also detect the key being used and adjust the vehicle settings in line with the use of the key. For instance, if you turn on the car while holding the key fob in your palm the windows and sunroof can be opened to ventilate the cabin. You can also set the speed limit to only be applied when the car is powered by the selected key. This feature can be useful when you lend your vehicle to a driver who has little experience.

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, hold the lock button until you release it and press the unlock button.

This will make it impossible for your smart key fob from having to send or receive any radio waves. This will dramatically extend its battery life. It is possible to reactivate the function by pressing the unlock and lock buttons again.

Some smart keys have anti-theft functions that prevent them being stolen by thieves. For example, Mercedes-Benz smart keys use rolling codes to block unauthorized access to the vehicle. When a smart key is put in the ignition, a computer within the car verifies the code in milliseconds prior beginning the engine. BMW makes use of a Display Key that has a tiny LCD screen with a color. This allows drivers to lock their cars, open them, and then start them without having to remove the smart key from their pocket.

Special Cases

Smart keys use rolling security codes to prevent hacking, and when placed in the ignition, the vehicle's computer verifies the code within milliseconds. Mercedes-Benz created this technology, which is currently utilized by luxury car brands.

Another useful feature is that most smart key systems will operate if the user forgot the key in the trunk or left it at an eatery or lost it during a hike. Some systems will also alert the driver when the battery is depleted. Certain brands also offer keys with covers specifically designed for smart keys to guard the fob from damage.
