Step-by-Step Programming Instructions for Your 2004 Pontiac Grand Prix Key Fob
Follow these detailed steps to program your 2004 Pontiac Grand Prix key fob. Ensure you have all key fobs you wish to program ready before starting, as the process will erase previously programmed fobs.
Preparation Before You Begin
- Get Comfortable: Sit in the driver’s seat of your 2004 Pontiac Grand Prix.
- Remove the Key: Take the ignition key out of the ignition lock cylinder.
- Close All Doors: Ensure all doors of your vehicle are completely closed.
Locating and Removing the MALL PGM Fuse
- Fuse Panel Location: Find the fuse panel, typically located inside the vehicle, often under the dashboard on the driver’s side or in the glove compartment. Refer to your owner’s manual for the exact location if needed.
- Identify MALL PGM Fuse: Locate the “MALL PGM” fuse within the fuse panel. Your owner’s manual or the fuse box diagram will help you identify the correct fuse.
- Remove the Fuse: Carefully remove the MALL PGM fuse from the fuse panel. This step is crucial for initiating the programming sequence.
Initiating Programming Mode with the Ignition Key
- Turn Ignition to ACC: Insert your ignition key into the ignition lock cylinder and turn it to the “ACC” (Accessory) position.
- Quickly Turn OFF and Back to ACC: Immediately turn the ignition key from the “ACC” position to the “OFF” position, and then back to the “ACC” position again within one second. This quick sequence is important for entering programming mode.
Triggering Programming Mode with the Door
- Open and Close Door: Open and then close any vehicle door. This action should trigger the remote control door lock receiver to enter the programming/diagnostic mode.
Listening for the Confirmation Chime
- Awaiting the Chime: Listen carefully for a chime sound. This chime indicates that the remote control door lock receiver has successfully entered the programming/diagnostic mode.
- Troubleshooting No Chime: If you do not hear a chime, you will need to restart the process from step 1 and carefully repeat each step.
Programming the 2004 Pontiac Grand Prix Key Fob Transmitter
- Press and Hold Lock and Unlock: 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 During Programming: You may hear a chime after 7 seconds, which confirms successful synchronization. After approximately 14 seconds, you should hear another chime, confirming successful programming of the key fob.
Programming Additional Key Fobs (If Necessary)
- Repeat for Each Fob: If you have additional 2004 Pontiac Grand Prix key fobs to program, repeat step 8 for each additional transmitter you want to program. You can program up to 4 transmitters in total.
Finalizing the Programming Process
- Remove Ignition Key: Take the ignition key out of the ignition lock cylinder.
- Reinstall MALL PGM Fuse: Return to the fuse panel and install the MALL PGM fuse back into its original location.
Verifying Key Fob Operation
- Test All Buttons: Test all the buttons on each programmed 2004 Pontiac Grand Prix key fob to ensure they are operating properly. Verify that the lock, unlock, and any other functions are working as expected.
Important Considerations When Programming Your Key Fob
- Erase Previous Programming: Be aware that once the keyless entry receiver enters programming mode, it erases all previously programmed transmitter information. Therefore, you must program all of your key fobs (both old and new) during this session.
- Program One Vehicle at a Time: Only program one vehicle’s remote control door lock receiver at a time. Programming multiple receivers simultaneously could lead to a transmitter being programmed to more than one receiver, causing confusion and potential issues.
- Seek Professional Help if Unsuccessful: If you encounter difficulties or are unable to successfully program your 2004 Pontiac Grand Prix key fob using these steps, it may be necessary to seek assistance from a professional mechanic or a locksmith specializing in automotive key programming.
By following these instructions carefully, you should be able to program your 2004 Pontiac Grand Prix key fob yourself and restore the convenience of remote keyless entry to your vehicle.
