If you have problems with yours, you may either visit the dealer or phone a locksmith.
The way a keyless entry system works is by releasing radio signals and then searching for a response signal from the key fob. If the system detects the signal, the car's doors are unlocked and the onboard computer activated. Certain systems have a second receiver on the car's trunk that opens automatically when you waggle your foot underneath it.
Each key fob is assigned an individual digital identification number by the manufacturer. The fob is programmed with an exclusive process known as "programming".

The receiver on the car checks the authenticity of the transmitter by an authentication and encryption process. If it is authorized, the computer on board unlocks the vehicle and begins the engine.
There are fears that a clever criminal could intercept the code transmitted between the key fob and the car. This would require the use of an instrument that records the transmission and then transmits it again when the system doesn't anticipate it. To help combat this, most keyless entry systems use a method called rolling code that guarantees that each new signal from the transmitter received by the car has a different counter than the previous one.
