Losing a car key or needing a spare is a common hassle for Pontiac Grand Prix owners. Fortunately, programming a new or existing key fob for your Pontiac Grand Prix can often be done without specialized tools, right in your driveway. This guide will walk you through the process of programming your key or remote transmitter to your vehicle’s remote control door lock receiver, allowing you to regain keyless entry and peace of mind.
Step-by-Step Guide to Programming Your Pontiac Grand Prix Key Fob
Before you begin, it’s crucial to understand that initiating the programming sequence will erase all previously programmed transmitters. Therefore, you’ll need to program all of your transmitters (both old and new) during this process to ensure they all function correctly. Also, ensure you are only programming one vehicle’s receiver at a time to prevent accidentally programming a transmitter to multiple vehicles.
Here’s how to program your Pontiac Grand Prix key fob:
-
Get Comfortable in the Driver’s Seat: Sit 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: Ensure 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 (refer to your owner’s manual for the exact location, often under the dashboard or in the engine compartment). Locate and remove the “MALL PGM” fuse. This fuse is related to the মাল্টিপ্লেক্সড অ্যাকচুয়েটর লজিক লিংক (MALL) system and Programmable GateWay Module (PGM), and removing it is part of the programming procedure.
-
Turn Ignition to ACC: Insert your key into the ignition lock cylinder and turn it to the “ACC” (Accessory) position.
-
Cycle Ignition ACC and OFF: Turn the ignition from the “ACC” position to “OFF,” and then back to “ACC” again within one second. This quick cycle is important 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’ll need to repeat steps 1 through 7 to restart the process.
-
Program the Transmitter(s): Take your first transmitter (key fob) and simultaneously press and hold both the “LOCK” and “UNLOCK” buttons for approximately 14 seconds. You might hear a chime after about 7 seconds confirming synchronization and another at 14 seconds confirming successful programming.
-
Repeat for Additional Transmitters: If you have additional transmitters to program (including your original working keys), repeat step 9 for each one.
-
Remove Key and Reinstall Fuse: Once you have programmed all desired transmitters, remove the key from the ignition lock cylinder. Then, go back to the fuse panel and reinstall the “MALL PGM” fuse you removed in step 4.
-
Verify Programming: Test each of your programmed transmitters to ensure they properly operate the door locks and other keyless entry functions of your Pontiac Grand Prix. Refer to your owner’s manual for specific details on “Keyless Entry System Operation” to confirm proper functionality.
By following these steps carefully, you should be able to successfully program your Pontiac Grand Prix car key and regain full keyless entry functionality. If you encounter any issues or are unsure about any part of this procedure, consulting a qualified automotive technician or your Pontiac owner’s manual is always recommended.
