Vehicle Smart Key Technology The smart key technology found in vehicles allows drivers to unlock and start their vehicle by just touching the door handle, or by putting the key into the pocket. It also permits a variety of other adjustments like seat positions and internal temperature settings, stereo presets, and mirror positioning. This could also create security worries. Security Smart keys are highly sophisticated key fobs with computers that communicate with a vehicle through one of the antennas that are embedded in the vehicle to open the doors and begin the engine. Contrary to conventional keys, which emit the same frequency signal each time they are pressed, smart key fobs transmit encrypted signals that are only compatible with the specific vehicle they belong to. This makes it harder for thieves with the latest technology to spoof or intercept the signal and use the key to take your car. For example, Mercedes' system — called Keyless Go — has an internal transponder which can identify the driver's key.

This will dramatically extend its battery life. You can always restart the function by pressing both the unlock and lock button again.
