Having issues with your 2009 Jeep Grand Cherokee key fob? Lost its functionality or added a new remote? You might be able to program it yourself without a trip to the dealership! This guide provides step-by-step instructions for programming your 2009 Jeep Grand Cherokee key fob, potentially saving you time and money. While these methods are based on manufacturer procedures, always double-check your vehicle’s owner manual for the most accurate instructions.
This article outlines two customer programming methods that you can attempt at home. Before starting, ensure you have all your key fobs ready, including any existing working ones and the new one you wish to program.
Method A: Standard Customer Programming
This method involves a sequence of button presses and ignition turns to enter programming mode and synchronize your key fobs.
Step 1: Resynchronize Existing Transmitter
Begin by resynchronizing your current transmitter. Press the LOCK button five times in quick succession, with approximately 2-second intervals between each press. After this, test if your transmitter is working. If it functions correctly, you may not need to proceed with further programming.
Step 2: Enter Run Position
Turn your Jeep Grand Cherokee’s ignition to the RUN position. Do not start the engine. Allow the ignition chimes to completely stop before moving to the next step.
Step 3: Initiate Programming Mode
Using an original, working transmitter, press and hold the UNLOCK button for a duration between 4 and 10 seconds.
Step 4: Engage Panic Button
While still holding the UNLOCK button, press and release the PANIC button for approximately 1 second. Then, release both buttons simultaneously. You should hear a chime sound, indicating that your Jeep has entered key fob programming mode. Allow up to 3 seconds for the chime to sound.
Step 5: Program Transmitter Buttons
On the transmitter you wish to program, press and hold both the LOCK and UNLOCK buttons at the same time for 1 second, and then release them. A short chime sound should be heard.
Step 6: Finalize Transmitter Programming
Immediately after step 5, press and release any button on the same transmitter. A chime sound will confirm successful programming, and the door locks may cycle.
Note: For the first transmitter programmed using this method, a chime might not sound in Step 6. However, it should sound when programming subsequent transmitters.
Step 7: Program Additional Transmitters (Optional)
If you have more key fobs to program, repeat steps 5 and 6 for each additional transmitter.
Step 8: Exit Programming Mode
Turn the ignition to the OFF position to exit the transmitter programming mode. The programming mode will automatically time out after 60 seconds (or 30 seconds for some models with Remote Start). Ensure all transmitter programming is completed within this timeframe.
Method B: Alternative Customer Programming
This is another method you can try if Method A doesn’t work or if you prefer a slightly different sequence.
Step 1: Resynchronize Transmitter (Method B)
As with Method A, start by resynchronizing your existing transmitter by pressing the LOCK button five times at 2-second intervals. Test the transmitter functionality and discontinue programming if it now works.
Step 2: Turn Ignition to Run (Method B)
Turn the ignition to the RUN position, ensuring the engine is not started and waiting for the chimes to stop.
Step 3: Initiate Programming Mode (Method B)
Using an original transmitter, press and hold the UNLOCK button for a duration between 4 and 10 seconds.
Step 4: Engage Panic Button (Method B)
Continue holding the UNLOCK button and press the PANIC button. Listen for a chime to indicate that the programming mode has been activated (allow up to 3 seconds).
Step 5: Program All Transmitters
Press a button on each transmitter you want to be programmed into the system. This includes previously programmed transmitters and any new ones. A chime should sound after each transmitter is successfully programmed.
Step 6: Exit Programming Mode (Method B)
Turn the ignition to the OFF position to exit the transmitter programming mode.
Important Considerations:
- Read Instructions Carefully: Before attempting any programming, thoroughly read through these instructions and ideally, consult your 2009 Jeep Grand Cherokee owner’s manual for any specific recommendations or variations.
- Working Original Transmitter: These methods often require a working original transmitter to initiate the programming sequence. If you don’t have a working key fob, you might need professional assistance.
- Chime Confirmation: Pay close attention to the chime sounds, as they are crucial indicators of successful steps and mode entry.
- Time Limits: Be mindful of the time limits in the programming mode to avoid timeouts and having to restart the process.
- Dealer Assistance: If you encounter difficulties or these methods do not work for your 2009 Jeep Grand Cherokee, it may be necessary to visit a qualified locksmith or your Jeep dealership for professional key fob programming.
By following these methods, you can attempt to program your 2009 Jeep Grand Cherokee key fob yourself. Remember to be patient and precise with each step. Good luck!
