Smart Car Keys With a smart car key, you can lock your doors or open your trunk without digging through your pockets for an actual key. It also lets you start your car by remote. Some smart keys employ rolling codes to stop theft by tech-savvy thieves. The code is checked by a computer in the vehicle before the engine is able to start. Security Smart keys communicate with the car using encrypted signals, unlike traditional keys which can be copied. These signals are used to unlock doors, start engines, and perform other functions.

These systems are ideal for parents who want to keep their children safe, or those with novice drivers. They function by sending signals to the car which are then processed by the vehicle's electronic system. The system can execute certain actions when a certain signal is received.

The smart key also makes use of a technology called rolling codes to help thwart thieves who are technologically adept. The vehicle's computer confirms that the rolling code is the same as the one projected by the key. This will stop anyone from using the key to unlock and start a car that was stolen.
