The good news is that programming a key fob for your 2005 Pontiac Grand Prix is a straightforward process that you can accomplish yourself without any special tools. This guide will walk you through the steps to program your key fob, allowing you to regain remote access to your vehicle quickly and easily. You can program up to four transmitters for your 2005 Pontiac Grand Prix.

Step-by-Step Key Fob Programming Instructions for Your 2005 Pontiac Grand Prix
Follow these steps carefully to program your 2005 Pontiac Grand Prix key fob:
- Get Comfortable in the Driver’s Seat: Ensure you are seated in the driver’s seat of your Pontiac Grand Prix.
- Remove the Key from the Ignition: Take the ignition key completely out of the ignition lock cylinder.
- Close All Doors: Make sure all doors of your vehicle, including the trunk or liftgate, are fully closed.
- Locate and Remove the MALL PGM Fuse: Find the fuse panel in your Pontiac Grand Prix. Consult your owner’s manual if you’re unsure of its location. Identify and remove the “MALL PGM” fuse. This fuse is related to the মাল্টিপ্লেক্সড অ্যাক্সেস কন্ট্রোল ল্যাচ (Multiplexed Access Control Latch) system, and removing it is part of the programming procedure.
- Turn Ignition to ACC: Insert your key into the ignition and turn it to the “ACC” (Accessory) position. This is typically the first position when you turn the key clockwise.
- Cycle Ignition ACC and OFF Quickly: Turn the ignition from the “ACC” position to the “OFF” position, and then back to “ACC” within one second. This quick cycling is crucial for initiating the programming sequence.
- Open and Close the Door: Open and then close any vehicle door. This action signals the system to enter programming mode.
- Listen for the Chime: After closing the door, listen carefully for a chime. This chime indicates that the remote control door lock receiver has successfully entered the programming/diagnostic mode. If you do not hear a chime, you will need to repeat the process from step 1.
- Program the Transmitter: 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.
- Confirmation Chimes: After about 7 seconds of holding the buttons, you may hear a chime confirming successful synchronization. After approximately 14 seconds, you should hear another chime. This second chime confirms that the key fob programming was successful.
- Program Additional Transmitters (If Necessary): If you have additional key fobs to program, repeat step 9 for each of them. Remember to program all key fobs you want to use during this session as previous programming is erased.
- Remove Key and Reinstall Fuse: Remove the ignition key from the ignition lock cylinder. Go back to the fuse panel and reinstall the “MALL PGM” fuse that you removed in step 4.
- Verify Programming: Test each programmed key fob to ensure it is operating correctly. Press the “LOCK,” “UNLOCK,” and other buttons to confirm they control the door locks and other keyless entry functions as expected.
Troubleshooting Tips
- No Chime: If you don’t hear the chime after step 8, double-check that you have followed all steps correctly, especially the timing of turning the ignition key and opening/closing the door. Ensure the “MALL PGM” fuse was indeed removed.
- Programming Fails: If the programming seems unsuccessful, ensure you are holding the LOCK and UNLOCK buttons for the full 14 seconds. Also, make sure you are using a compatible key fob for your 2005 Pontiac Grand Prix.
- Battery Issues: A weak battery in your key fob can sometimes cause programming problems. Try replacing the battery in your key fob before attempting to program it.
By following these instructions, you should be able to successfully program your 2005 Pontiac Grand Prix key fob and restore the convenience of remote keyless entry. If you continue to experience issues, it may be necessary to consult a professional automotive locksmith or dealership.
