Having trouble with your 2003 Pontiac Grand Am Key Fob? Losing the ability to remotely lock and unlock your doors, or pop the trunk, can be a real inconvenience. Luckily, programming a new or replacement key fob for your 2003 Pontiac Grand Am is a process you can often handle yourself, potentially saving you a trip to the dealership. This guide provides a comprehensive walkthrough on how to program your 2003 Pontiac Grand Am key fob, ensuring you regain full remote access to your vehicle.
Before you begin, it’s crucial to understand a few important points about programming your Pontiac Grand Am key fob. The system requires all key fobs intended for use with your vehicle to be programmed in a single session. Initiating the programming sequence will erase all previously programmed key fobs. Therefore, if you still have working key fobs, ensure you have them all present and ready to be programmed along with any new ones. Up to four key fobs can be programmed to your 2003 Pontiac Grand Am. It’s also important to avoid programming near other vehicles that might be in keyless entry programming mode to prevent accidental programming to the wrong vehicle. The order in which you program the key fobs matters; the first one programmed will be recognized as key fob #1, the second as #2, and so on.
To program your 2003 Pontiac Grand Am key fob, you will need a scan tool. This tool is essential for communicating with your vehicle’s Body Control Module (BCM) and initiating the key fob programming sequence. Here’s a detailed step-by-step guide:
-
Prepare Your Vehicle and Scan Tool: Begin by connecting your scan tool to your 2003 Pontiac Grand Am’s diagnostic port. Make sure the ignition is turned ON, but the engine should remain OFF.
-
Navigate to Keyless Entry Programming: Using your scan tool, navigate through the menu options. Typically, you’ll need to select “Body and Accessories,” then proceed to “Keyless Entry.” From there, look for “Special Functions” and then “BCM.” Finally, select the option labeled “Program Key Fobs.”
-
Specify Number of Key Fobs: The scan tool will prompt you to select the number of key fobs you intend to program. Choose the correct number, up to a maximum of four.
-
Initiate Key Fob Programming: Take your first key fob. Simultaneously press and hold both the LOCK and UNLOCK buttons on the fob for approximately 15 seconds.
-
Confirmation of Programming: After holding the buttons for 15 seconds, the power locks on your 2003 Pontiac Grand Am should cycle (lock then unlock). This lock cycling indicates that the first key fob has been successfully programmed.
-
Program Additional Key Fobs (If Applicable): If you are programming more than one key fob, repeat step 4 and 5 for each additional key fob you wish to program. Remember to do this within the same programming sequence.
-
Exit Programming Mode and Verify: Once you have programmed all desired key fobs, remove the scan tool from your vehicle. Exit the vehicle completely. Now, test the programming by attempting to lock and unlock the doors using each of your programmed key fobs. Also, test all other functions on each fob, such as the trunk release or panic button, to ensure everything is working correctly.
By following these steps, you should be able to successfully program your 2003 Pontiac Grand Am key fob and restore the convenience of remote vehicle access. Remember to always double-check your connections and follow the scan tool prompts carefully during the process. If you encounter any issues, consulting your vehicle’s repair manual or seeking professional assistance from a qualified automotive technician may be necessary.
