A unique process of technology known as "programming" is used to configure the fob with the car's specific system. This usually involves turning on the car's ignition multiple times in a particular sequence, and could also involve pushing or pulling various buttons and levers or the removal of fuse.
When a key fob is programmed to the car's keyless entry system, it transmits its digital identity code, along with a function code that tells the car what to do (lock or unlock the trunk or open the trunk). The receiver on the car confirms the identity of the transmitter through an authentication and encryption process. The onboard computer will unlock the vehicle and start the engine if it is authenticated.
A skilled criminal could snoop and then use the code that is transmitted between the keyfob's and the vehicle. This will require an instrument that records the transmission, and then transmits it again in the event that the system doesn't want it. Most keyless entry systems use rolling codes to stop this. This ensures that every new transmitter signal received by a vehicle has a counter that is different from the previous one.

After the new battery is in place, test your key fob for the second time to see if the battery has fixed your problem. If it doesn't it, you'll have to determine whether your device has an issue that's more complex that requires a professional diagnosis and repair. If this is the case, you could require it to be reprogrammed by a dealer, or you may need to buy a replacement key fob altogether.
