Car Key Repair - How to Fix a Dead Remote

Keyless Entry System
Rather than needing to fumble around with keys in your pocket or purse instead, stroll up to your car, press an icon on the key fob, and then open the doors and start the engine. It's a convenient feature that has made the experience of driving a car more enjoyable and more secure. However, just like any other device it's possible that the keyless entry system may fail due to repeated use or because of other factors. If you have problems with yours, you can either visit the dealer or call an locksmith.
The way that a keyless entry system operates is by releasing radio signals, and then searching for a corresponding response signal from the key fob. If the system recognizes the signal, it will trigger to open the doors of the vehicle and activate the onboard computer. Certain systems include an additional transmitter in the trunk of the car that opens it when you waggle one foot underneath it.
Each key fob is given a unique digital identification code by the manufacturer. The fob is programmed by a unique process called "programming". This usually involves turning on the ignition of the vehicle multiple times in a particular sequence, and could also require pulling or pushing various buttons and levers or taking out fuse.
When a key fob is programmed to your specific vehicle's keyless entry system it transmits its digital identification code along with a function code that instructs the car what to do (lock or unlock the trunk or open the trunk). The car's receiver checks the authenticity of the transmitter by an authentication and encryption process. If it is authorized, the computer on board unlocks the vehicle and then starts the engine.
A skilled criminal could snoop and use the code sent between the keyfob and the vehicle. This would require a special device to record the transmission and then retransmit it later when the system isn't expecting it. To combat this, most keyless entry systems use the rolling code method that guarantees that each new signal from the transmitter received by the car has a different counter value than the previous one.
