Step 1: On the backside of the key fob, there is a small latch that needs to be pulled to the side to release the metallic spare key.

How To Open A Jeep Key Fob

Before attempting to replace the battery from the fob, remove any key rings that might cause issues when splitting the key fob open. You will also want to find an appropriate-sized flat head screwdriver and the correct replacement battery for your Jeep’s key fob. The latest Jeep keyfobs have a CR2032 battery inside, but you should consult with your local dealership’s part counter to ensure you have the right battery and to source a good quality replacement that will last you a while. To open the key fob, begin by placing the flat head screwdriver at the seam near the keyring mount and press down to split the key fob into two. Never twist the screwdriver since that can crack the plastic key fob cover. Now that you have the key fob open, you can replace the battery.

Over time, the battery in these fobs will lose its charge and need to be replaced. If youve never done this before on your Jeep Grand Cherokee fob, you might be wondering how to go about this process.

    To change the battery on a Jeep Grand Cherokee key fob, all you have to do is remove the fobs internal key, open the fob, and remove the old battery. You can then install the new battery, reassemble the fob, and replace the key for a fully charged fob that you can use instantly.

    As you disassemble the key fob, you will see that it consists of five parts, as follows:

    • The first half of the housing that has holes for the keypad and the key attached to it
    • The second half of the housing that holds the battery in place

    Before you remove the battery from its place, I recommend making a mental note of the polarity of the old battery so that you are not lost when you put in the replacement. Additionally, pay attention to the circuit board. If its tiny components are loose or falling out, make necessary adjustments to put it back in its original position.

    Lastly, take care not to scratch or bend the metal electrical contacts if using a screwdriver to pry out the old battery.

    Jeep Key Battery Replacement: Signs Your Need A Change

    Sometimes, you can’t tell if your problems will be solved with a Jeep key battery replacement. Green Bay drivers often recognize these signs that it’s time to change the battery in a Jeep key fob:

    • Unlocking and locking takes multiple tries: It throws off your rhythm when your locks don’t respond, so it’s likely that these are the first signs Appleton drivers recognize. If you find yourself pressing the buttons repeatedly just to get the key fob to communicate, change the battery in your Jeep key fob.

    • Limited range: Your key fob battery works up to 50 feet away from the vehicle. When it’s time for a battery change, you’ll notice the range decreasing.

    In the best conditions, your Jeep key fob battery lasts 3 – 4 years. Once you’re reaching the limit of your battery, trust the Kolosso CDJR parts center or a local hardware store for the right battery for your key fob.

    Cost To Replace A Broke Jeep Grand Cherokee Key Fob

    Many people are hesitant to go through the process of replacing their old Jeep Brand Cherokee key fob with a new one out of concern for the overall cost.

    The good news is that most key fob replacements relatively affordable, ranging between $50 and $100. However, there are instances where you could potentially pay as high as $400, depending on the generation/production year of your model and labor costs.

    Newer Jeep Grand Cherokees feature more advanced technological features that consequently increase the overall cost of their required key fobs.

    Dealerships and auto stores might also require you to pay for 30-mintes to an hour of labor to program your new key fob, which will significantly increase the cost, whereas others will only require you to pay for the fob itself and program it for free.

    You can potentially program older key fobs with features limited to locking and unlocking your car by yourself, but if you have a newer generation, youll need professional help.

    Make sure you research your options and compare quotes before deciding who to purchase a replacement from to ensure you arent paying more than absolutely necessary.
