If your keyless entry fob or remote came from the factory for your vehicle, consult the vehicle owner's manual or the dealership's customer service for specific instructions describing how to program the fob. Some manufacturers do not publish keyless entry programming information in the vehicle owner's manual, but the remotes can often still be programmed.
Aftermarket keyless entry systems should explain programming in the accompanying owner's manual, but it is a good idea to confirm this before purchasing an aftermarket keyless entry system. Smart keys that do not have to be inserted in the ignition, such as those that come with late model Mercedes-Benz, Lexus and Porsche vehicles, can be reprogrammed in some instances but usually must be programmed by the dealership.Learn more about Car Parts & Maintenance
