Turn off the ignition and remove the key. Return the "Mall Pgm" fuse to the fuse block.The Pontiac Grand Prix was first introduced in 1962 as a full-sized car that was recognized in the luxury-car genre as well. The 2006 came in three variations; Grand Prix, GT and GXP, each with a larger engine than the last. The car also came with an optional keyless remote-entry system. With this remote you are able to unlock or lock the doors as well as set off the car alarm with the touch of a button. To replace a Grand Prix keyless remote, you must purchase a new one from a retailer and then reprogram it using a working key for the car.
