If you find that your key fob no longer working, try a few quick fixes before going to the dealer. These suggestions could save you money.
Keyless Entry System

Each key fob is given an unique identification code by the manufacturer. A proprietary technical process called "programming" is used to configure the fob with the car's specific system. This typically involves turning the car's ignition multiple times in a particular sequence, and could include pulling or pushing various levers and buttons or removing fuse.
Once a key fob is programmed to the vehicle's keyless entry system it transmits the digital identity code along with an operation code that tells the car what to do (lock or unlock the trunk or open the trunk). The receiver on the car checks the authenticity of the transmitter by an authentication and encryption process. If it's authorized, the onboard computer unlocks vehicle and starts the engine.
There are fears that a criminal with a sly approach could intercept the code transmitted between the key fob and the car. This would require a specific device to record the transmission and then transmit it again in the event that the system doesn't anticipate it.
