For owners of the 1999 Jeep Grand Cherokee, the key fob is more than just a convenient accessory; it’s an integral part of your vehicle’s security and accessibility. This handy remote allows you to effortlessly lock and unlock your doors, and even activate a panic alarm in emergencies. If you’ve recently acquired a new key fob or find your current one unresponsive, programming it is a straightforward process you can accomplish yourself, saving time and money. This guide provides two easy-to-follow methods to program your 1999 Jeep Grand Cherokee key fob quickly and efficiently.
Key Fob and Key Information
Method A: The Standard Programming Procedure
This method is commonly effective for programming your 1999 Jeep Grand Cherokee key fob and involves a sequence of button presses and ignition key turns. Follow these steps carefully to ensure successful programming:
-
Initiate the Programming Sequence: Begin by pressing the “lock” button on your new key fob five times. Ensure you maintain a brisk pace, with no more than two seconds between each button press. This rapid succession signals the system to prepare for programming.
-
Turn On the Ignition: Insert your Jeep Grand Cherokee’s key into the ignition and turn it to the “ON” position. This activates the vehicle’s electrical system and prepares it to receive the key fob programming signal. Do not start the engine; simply turn the key to the point where the dashboard lights illuminate.
-
Engage Unlock and Panic Buttons: Next, press and hold the “unlock” button on the key fob. While holding the “unlock” button, within ten seconds, press and hold the “panic” button for just one second. This combination of button presses is crucial for initiating the programming mode.
-
Release and Listen for the Chime: Release both the “unlock” and “panic” buttons simultaneously. Immediately listen attentively for a chime sound. This chime is your confirmation that the vehicle has successfully entered programming mode. It should typically be audible within three seconds of releasing the buttons.
-
Synchronize Lock and Unlock: Press and release both the “lock” and “unlock” buttons on the key fob at the same time, and then release them. This step further synchronizes the key fob with your Jeep’s system.
-
Finalize Programming with Any Button: Press and release any button on your key fob – it could be “lock,” “unlock,” or “panic.” After pressing a button, listen for a quick chime sound. This final chime confirms that the programming process is complete and your key fob is now recognized by your 1999 Jeep Grand Cherokee.
-
Exit Programming Mode: Turn your ignition off by turning the key back to the “OFF” position and removing it from the ignition. Your key fob should now be fully programmed and ready to use. Test all buttons to ensure they are functioning correctly, locking and unlocking your doors as expected.
Method B: An Alternative Programming Approach
If Method A does not successfully program your 1999 Jeep Grand Cherokee key fob, Method B offers an alternative sequence that may work. This method also relies on button presses and ignition key manipulation:
-
Rapid Lock Button Presses: Begin by pressing and releasing the “lock” button on your key fob five times, maintaining approximately two-second intervals between each press. This consistent rhythm is important for this method.
-
Ignition Activation: Turn the ignition of your Jeep Grand Cherokee to the “ON” position, just as in Method A. Ensure the dashboard lights are illuminated, but the engine is not started.
-
Unlock and Panic Button Combination: Press and hold the “unlock” button on the key fob for up to ten seconds. While continuing to hold the “unlock” button, press and briefly hold the “panic” button. Listen carefully for the confirmation chime, which should sound within three seconds of pressing the panic button.
-
Button Programming Confirmation: To complete the programming, press any button on the key fob. Listen for a second chime sound, which indicates that a button has been successfully programmed and the key fob is now recognized.
-
Exit Programming: Turn the ignition off to exit the programming mode. Test your key fob to verify that all buttons are working correctly to control your vehicle’s locks.
Troubleshooting and Tips for Successful Programming
-
Fresh Battery: Before you begin either programming method, ensure your key fob has a fresh 3-volt battery installed. A weak battery can prevent the fob from transmitting a strong enough signal during the programming process. This is a common issue, and a new battery often resolves programming difficulties.
-
Timing is Key: Pay close attention to the timing specified in each step. The intervals between button presses and the duration of holding buttons are important for the system to recognize the programming sequence.
-
Listen for the Chimes: The chime sounds are crucial feedback indicators. Listen carefully for them after each relevant step to confirm successful progression through the programming sequence.
-
Repeat the Process: If the key fob doesn’t program on the first attempt, carefully repeat the chosen method from the beginning. Double-check each step and timing to rule out any missed steps or errors.
-
Check Compatibility: Ensure that the key fob you are trying to program is indeed compatible with your 1999 Jeep Grand Cherokee. Key fobs are specific to vehicle models and years.
When to Consider Professional Programming
While these DIY methods are generally effective for 1999 Jeep Grand Cherokee Key Fob Programming, there are situations where professional assistance might be necessary:
-
Persistent Failure: If you have meticulously followed both Method A and Method B multiple times and are still unable to program your key fob, there might be an underlying issue with the key fob itself or your vehicle’s receiver system.
-
Dealer Programming: Your local Jeep dealer possesses specialized diagnostic tools and equipment that can program key fobs, even in cases where DIY methods fail. While dealer programming can be more expensive, typically ranging from $150 to $300, it guarantees professional service and resolution. Consider contacting your Jeep dealer to schedule an appointment if you encounter persistent problems.
By following these methods and troubleshooting tips, you should be able to successfully program your 1999 Jeep Grand Cherokee key fob and regain the convenience and security it provides.
