Is your 2003 Buick Rendezvous Key Fob not working? Or did you get a new key fob and need to program it to your vehicle? This guide provides simple, step-by-step instructions to program your 2003 Buick Rendezvous key fob yourself. This process will erase all previously programmed remotes, so ensure you have all the key fobs you intend to use with your vehicle ready before you begin.
Step-by-Step Programming Guide
Follow these instructions carefully to program your 2003 Buick Rendezvous key fob:
-
Gather Your Remotes: Collect all key fobs you wish to program. Remember, this procedure will clear all existing remotes, so you must program all of them at once.
-
Prepare the Vehicle: Ensure all doors are closed. Press and hold the UNLOCK button located on the driver’s side door panel. Do not release the button throughout the next steps until instructed.
-
Ignition Key Insertion (Attempt 1): Insert the ignition key into the ignition switch, but do not turn it on.
-
Key Cycling (Attempt 1): Remove the key from the ignition. Then, immediately insert and remove the key again. Finally, insert the key one last time and leave it in the ignition switch, without turning it.
-
Release Unlock Button (Attempt 1): Release the UNLOCK button on the driver’s door. Listen for a chime. The car should chime three times to indicate that it has entered programming mode.
- If No Chime (Attempt 1 Failed): If you do not hear three chimes, the vehicle may not have entered programming mode with the previous steps. Proceed to the “Alternative Ignition Steps” below and try again.
-
Program the Key Fob: Press and hold both the LOCK and UNLOCK buttons simultaneously on the key fob you are programming. Continue holding the buttons until the car chimes twice. This may take up to 30 seconds. If you don’t hear a chime after 30 seconds, release the buttons; the chime should sound shortly after releasing. The two chimes confirm successful programming of that key fob.
-
Program Additional Key Fobs: Repeat Step 6 for each additional key fob you need to program.
-
Exit Programming Mode: Remove the key from the ignition switch to exit the key fob programming mode.
Alternative Ignition Steps (If Initial Attempt Fails)
If the initial steps (3-5) did not result in the car chiming to enter programming mode, try reversing the order of steps 2 and 3 as follows:
-
Prepare the Vehicle (Alternative): Close all doors.
-
Ignition Key Insertion (Alternative): Insert the ignition key into the ignition switch, but do not turn it on.
-
Hold Unlock Button (Alternative): Press and hold the UNLOCK button located on the driver’s side door panel. Do not release the button.
-
Key Cycling (Alternative): Remove the key from the ignition. Then, immediately insert and remove the key again. Finally, insert the key one last time and leave it in the ignition switch, without turning it.
-
Release Unlock Button (Alternative): Release the UNLOCK button on the driver’s door and listen for the three chimes indicating programming mode.
- Proceed with Step 6-8: Once the car chimes and enters programming mode using either set of steps, continue with steps 6 through 8 to program your key fobs.
