The cost of a key fob will differ based on the vehicle model and the key type however they usually cost between $85 and $400. This includes labor costs to program the keyfob, as well as any replacement parts.

To make the process more difficult, these car key fobs utilize a specific software system to communicate with the car's onboard computer.

If you replace your keys, you will have to program the new key fob into the car to allow it to function.

The most common method to do this is by using a car key programming tool that is compatible with the brand of the vehicle. This tool lets the locksmith connect to the onboard diagnostics port (OBD) in the vehicle and then enter the programming mode. The key programming tool can either be an inexpensive handheld device or a fancy one that can perform many things beyond key programming (like reading and cloning Eeprom files within the ECU).
