So you’re having trouble programming your key fob for your 2000 Pontiac Grand Prix? You’re not alone. Many owners encounter difficulties when trying to get their keyless entry remotes to sync up with their vehicle. This guide is based on a real user experience and details a potentially successful, albeit unconventional, method for programming your 2000 Grand Prix Key Fob.
Let’s dive into the process this user went through. They initially tried standard methods, including the “Billboost method,” but had no luck. Another common programming procedure also failed to yield results. This led to some experimentation and the discovery of a unique approach.
During the initial attempts using the Billboost method, the car didn’t produce the expected single “ding” to indicate programming mode. Instead, something different happened. The car would “ding” once, accompanied by a flash of the Seat Belt Warning lamp. This sequence then repeated, progressing to two dings and flashes, then three, and finally four, before looping back to one. This cycle of 1, 2, 3, 4 dings and flashes continued, preventing the user from proceeding with the standard programming steps.
After a few unsuccessful tries, the user experimented with an intervention during this unusual cycle. The successful programming seemed to occur in one of two variations of this modified method:
Method Variation 1: Interrupting the Cycle
- Follow standard procedures up to the point of turning the ignition to ACC (Accessory) the second time and opening and closing the driver’s side door.
- Instead of waiting for the expected single programming “ding,” observe the car’s unusual 1, 2, 3, 4 ding and light flash cycle.
- While the car is actively cycling through these dings and flashes, press and hold both the “Lock” and “Unlock” buttons on the key fob simultaneously.
- Observe if this action interrupts the cycle. In this user’s experience, the cycling stopped, followed by a single “ding” after a few seconds.
- After this single “ding,” proceed to program your first key fob by holding down the “Unlock” and “Lock” buttons for a few seconds. You should hear another single “ding” to confirm programming. Holding the buttons longer than a few seconds did not seem to produce any further response.
- Immediately repeat step 5 for your second key fob. Again, a single “ding” should confirm successful programming.
- Turn the ignition off, replace the PGM fuse (if you removed it as part of other methods), and test both key fobs to ensure they are working correctly.
Method Variation 2: Waiting for Cycle Completion (Potential Coincidence)
- Perform the same initial steps as in Variation 1.
- Allow the car to complete its 1, 2, 3, 4 ding and flash cycle until it naturally stops on its own.
- Immediately after the cycle stops, press and hold the “Unlock” and “Lock” buttons on your first key fob. Listen for a single “ding” to confirm programming.
- Repeat step 3 for your second key fob.
- Turn the ignition off, replace the fuse, and test your key fobs.
The user wasn’t entirely sure whether the success was due to interrupting the cycle or if it was a coincidence of pressing the buttons just as the cycle finished on its own during the third attempt. Regardless, both scenarios resulted in successfully programmed 2000 Grand Prix key fobs.
Testing Your Newly Programmed Fobs
After attempting either of these methods, it’s crucial to test both key fobs to confirm they are now correctly programmed to your 2000 Pontiac Grand Prix. Try locking and unlocking the doors, as well as testing any other functions your key fob may have, such as the trunk release or panic button.
This user’s experience highlights that sometimes, standard procedures don’t work, and a bit of experimentation, combined with understanding your vehicle’s unique responses, can lead to a solution. If you are struggling to program your 2000 Grand Prix key fob using conventional methods, trying one of these variations might be the key to success.
