Lost your key fob or need to program a new one for your 2003 Pontiac Grand Prix? Don’t worry, programming your key fob at home is easier than you might think. This guide provides clear, step-by-step instructions to get your key fob working quickly, saving you time and money compared to dealership programming.
Before you begin, ensure you have all the key fobs you intend to use with your vehicle. Programming a new fob will erase any previously programmed fobs from the system’s memory. You’ll need to reprogram all of them again following these steps.
Here’s how to program your 2003 Pontiac Grand Prix Key Fob:
-
Turn the Ignition Off: Remove the key completely from the ignition.
-
Locate and Remove the MALL/BCM PGM Fuse: Find the fuse box in your Pontiac Grand Prix. Consult your owner’s manual or the fuse box cover legend to identify the fuse labeled “MALL” or “BCM PGM”. Once located, remove this fuse.
-
Ignition Cycling: Close all vehicle doors. Insert the key into the ignition. Quickly turn the ignition to the ACC (Accessory) position, then back to OFF, and then back to ACC again. Remember, ACC is the position just before the engine starts, and OFF is where you can remove the key. Complete these steps swiftly and finish with the ignition in the ACC position.
-
Enter Programming Mode: Open and then close the driver’s side door. The vehicle will chime to indicate that it has entered key fob programming mode.
-
Program the Key Fob: On the key fob you wish to program, press and hold both the LOCK and UNLOCK buttons simultaneously. The vehicle will chime twice to confirm successful programming of that fob. If you have additional key fobs to program, repeat this step for each one. It’s important to note that after pressing the buttons, you might hear an initial chime within 7 seconds, but wait approximately 14 seconds for a second chime to ensure successful programming.
-
Remove Key from Ignition: Once you have programmed all desired key fobs, remove the key from the ignition.
-
Reinstall the Fuse: Return to the fuse box and reinstall the “MALL/BCM PGM” fuse you removed in step 2.
-
Test Your Key Fobs: Test each programmed key fob to ensure they are working correctly with your 2003 Pontiac Grand Prix.
Programming is now complete! You should now be able to lock and unlock your doors, and use other remote functions with your newly programmed 2003 Pontiac Grand Prix key fob.
