Is your 2005 Pontiac Montana Key Fob no longer working, or did you recently purchase a new key fob remote and need to program it? Programming your key fob for your Pontiac Montana can seem daunting, but it’s actually a straightforward process you can accomplish right at home. This guide provides easy-to-follow, step-by-step instructions to get your 2005 Pontiac Montana key fob programmed quickly and efficiently.
What You Need Before You Begin
Before starting the programming procedure for your 2005 Pontiac Montana key fob, ensure you have everything prepared. It’s crucial to have all the key fobs you intend to use with your vehicle present because the programming process will erase previously programmed remotes. You will need to reprogram all of them during this session. Make sure you have your Pontiac Montana key and locate the fuse panel, which is accessed by opening the front passenger door. Knowing the location of the “BCM PRGRM” fuse within this panel, as indicated on the fuse panel legend, is essential for the process.
Step-by-Step Programming Instructions
Follow these steps carefully to program your 2005 Pontiac Montana key fob:
-
Turn Off the Ignition: Begin by removing the ignition key from your Pontiac Montana. Ensure the ignition is completely off before proceeding to the next step.
-
Locate and Remove the “BCM PRGRM” Fuse: Open the front passenger door to access the fuse panel. Refer to the fuse panel legend to accurately locate the “BCM PRGRM” fuse. Once found, remove this fuse. This step is critical for initiating the programming sequence.
-
Close All Doors: Ensure all vehicle doors are completely closed. This includes both side doors and the rear liftgate. Properly closing all doors is necessary for the system to enter programming mode correctly.
-
Insert and Turn the Key to ACC: Insert your key into the ignition switch. Turn the ignition key to the “ACC” (Accessory) position. Do not start the engine; simply turn the key to the accessory position where some electrical functions are enabled.
-
Cycle Ignition ACC to OFF: From the “ACC” position, quickly turn the key back to the “OFF” position and then immediately back to “ACC” within one second. This rapid cycling of the ignition is part of the signal to initiate programming.
-
Open and Close the Door: Open and then close any vehicle door. Upon completing this step, you should hear a chime. This chime is an auditory confirmation that your 2005 Pontiac Montana has successfully entered the key fob programming mode.
-
Program the First Remote: Take the first key fob you wish to program. Press and hold down both the “LOCK” and “UNLOCK” buttons simultaneously for approximately 14 seconds. It’s important to continue holding both buttons for the full duration. You may hear a chime around 7 seconds, indicating synchronization, but continue holding until you hear a second chime at approximately 14 seconds. This second chime confirms successful programming of the remote.
-
Program Additional Remotes (If Necessary): If you have additional key fobs to program, including any previously working remotes, repeat step 8 immediately for each additional remote. It is crucial to program all remotes you intend to use in this session as previous programming is erased.
-
Remove Key from Ignition: Once you have programmed all desired key fobs, remove the key from the ignition switch.
-
Reinstall the “BCM PRGRM” Fuse: Return to the fuse panel and reinstall the “BCM PRGRM” fuse back into its original location. Ensure it is firmly seated in the fuse panel.
-
Test the Remotes: Finally, test each programmed key fob to ensure they are working correctly. Press the LOCK and UNLOCK buttons to verify that they properly control the door locks of your 2005 Pontiac Montana.
Troubleshooting Tips
If you encounter issues programming your 2005 Pontiac Montana key fob, consider these troubleshooting tips:
- Fuse Location: Double-check that you have removed and reinstalled the correct “BCM PRGRM” fuse. Refer to your vehicle’s fuse panel diagram to confirm the accurate location.
- Battery Condition: Ensure the batteries in your key fobs are not depleted. A low battery can prevent the fob from transmitting the signal needed for programming. Try replacing the batteries with fresh ones and attempt the programming sequence again.
- Timing: The timing in steps 5 and 8 can be sensitive. Make sure you are cycling the ignition quickly and holding the buttons for the specified duration. If you are unsure, try the steps again, paying close attention to the timing.
- Procedure Repetition: If the programming is unsuccessful on the first attempt, carefully reread the instructions and repeat the entire procedure from the beginning. Sometimes, a step might be missed or not performed precisely, and restarting the process can resolve the issue.
