Car Key Repair - How to Fix a Dead Remote

Keyless Entry System

A keyless entry system operates by sending radio signals, and then looking for the response signal from the key fob.

Each key fob is equipped with a unique digital identification code, which is issued by the manufacturer. The fob is programmed with a proprietary process called "programming".

Once the key fob has been programmed into your car's keyless system it transmits a digital identification code and a function code that tell the car what to (lock the trunk, unlock it or open the trunk). The receiver on the car confirms the identity of the transmitter through an authentication and encryption process. The computer on board will allow the vehicle to be opened and start the engine when it is authenticated.

This would require a special device to record the transmission then retransmit it later when the system isn't expecting it.
