What is car programming?

Car key programming is the process of synchronizing a car key with the car’s immobilizer system. The immobilizer system is a security feature that prevents the car from being started without the correct key.

There are two main types of car keys: transponder keys and keyless entry remotes. Transponder keys have a small chip embedded in them that contains a unique code. This code is read by the immobilizer system when the key is inserted into the ignition. If the code matches, the car will start.

Keyless entry remotes allow you to lock, unlock, and start your car without having to use the key in the ignition. Keyless entry remotes also have a chip embedded in them, but this chip is used to communicate with the car’s security system.
