Programming Car Keys at Home
Car key reprogramming is a process that requires special equipment that only an auto locksmith has access to. Some manufacturers have technology which stops anyone other than the dealership from reprogramming keys.
Start the process by inserting one of your blank keys into the ignition but not activating the engine. The security light should come on and remain illuminated for three seconds. If you can hear the sound of the lock, then the procedure has been successful.
