Lost or need to replace your key fob for your 2005 Pontiac Grand Prix? Don’t worry, programming a new key fob can often be done right in your driveway without any special tools. This guide will walk you through the process of programming your 2005 Grand Prix key fob, allowing you to regain keyless entry and remote locking functionality quickly and easily. You can program up to four transmitters for your vehicle.
Step-by-Step Programming Instructions
Follow these steps carefully to program your 2005 Grand Prix key fob:
-
Prepare Your Vehicle: Begin by sitting in the driver’s seat of your 2005 Pontiac Grand Prix. Ensure the ignition key is removed from the ignition lock cylinder and all vehicle doors are fully closed.
-
Locate and Remove the MALL PGM Fuse: You’ll need to access your vehicle’s fuse panel. Find the fuse labeled “MALL PGM” and remove it. Consult your owner’s manual if you are unsure of the fuse panel location or fuse identification.
-
Ignition Cycling: Turn the ignition lock cylinder to the ACC (Accessory) position. Immediately turn the ignition lock cylinder OFF, and then back to the ACC position again within one second. This quick cycling is crucial for initiating the programming sequence.
-
Door Activation and Chime Confirmation: Open and then close any vehicle door. Listen carefully for a chime sound. This chime indicates that the remote control door lock receiver has successfully entered the programming/diagnostic mode. If you do not hear a chime, repeat steps 1 through 4 again.
-
Transmitter Synchronization: Take the key fob you wish to program. Press and hold both the LOCK and UNLOCK buttons on the transmitter simultaneously for approximately 14 seconds. After about 7 seconds, you might hear a chime confirming synchronization, and after 14 seconds, another chime confirms successful programming of that transmitter.
-
Programming Additional Transmitters: If you have additional key fobs to program, repeat step 5 for each transmitter. Remember, once you enter programming mode, all previously programmed transmitters are erased, so you must program all desired key fobs at this time, up to a maximum of four.
-
Reinstall the MALL PGM Fuse: After programming all key fobs, remove the ignition key from the ignition lock cylinder. Return to the fuse panel and reinstall the MALL PGM fuse in its original location.
-
Verification: Thoroughly test all programmed key fobs to ensure they are operating correctly. Verify that the lock, unlock, and any other functions are working as expected. Refer to your owner’s manual for “Keyless Entry System Operation” if needed to understand all functionalities.
Important Programming Notes
- Erase Previous Programming: Be aware that when the keyless entry receiver enters programming mode, it erases all previously stored transmitter information. Therefore, you must program both your old and new transmitters during this session.
- Program One Vehicle at a Time: To avoid accidentally programming a transmitter to multiple vehicles, only program one vehicle’s remote control door lock receiver at a time.
- Chime Confirmation is Key: The chime sound is your confirmation that the system has entered programming mode. If you miss the chime, restart from step 1 to ensure proper programming.
By following these steps, you should be able to easily program your 2005 Grand Prix key fob and restore the convenience of remote keyless entry to your vehicle.
