It also permits many other adjustments like seat position the internal temperature setting and mirror position. However, this can also create security concerns. Security Smart keys are advanced electronic keys that communicate with the vehicle using one of the antennas built into the car to unlock doors and start the engine. Contrary to conventional keys, which emit the same frequency signal each time they are activated, smart keys transmit encrypted signals that are only compatible with the car they belong to. This makes it harder for tech-savvy criminals to spoof or intercept the signal, and use your key to steal your car. Mercedes' Keyless Go system for instance, comes with an internal transponder that can identify the driver's keys. The Smart Key automatically unlocks and opens the doors and the tailgate when it is within 1.5 meters. It also begins the engine by pressing the key. Additionally certain smart keys- like those from BMW — have individual user settings that let the driver adjust the mirrors, seat and the position of the steering wheel as well as audio preferences at the push of a button. They also come with a backup lock, which keeps the vehicle from starting without the key in the ignition. This technology assists drivers from locking their car, especially when searching through a purse or backpack to find keys in a parking area filled with strangers or on an area with high crime rates.

Convenience The smart key is perfect for those who are on the move and need to get to their destination.

A computer inside the vehicle reads the code and checks it prior to launching the engine. Many systems also have a backup mechanical system that is an unnoticed key blade to be used for styling purposes.
