How car key programming works in San Antonio

Programming tells the car’s immobilizer to accept a key. It is done with a diagnostic tool plugged in under the dash, and on many makes it needs a security code read from the car. A key that is cut but not programmed will open the door and then fail to start the engine.

Some cars force a wait of ten minutes or more before they accept a new key. That delay is built into the car.
