Identifying the Key Fob
When it comes to changing the battery in your Jeep Wrangler key fob, the first step is to identify the key fob itself. The key fob is a small, handheld device that is used to lock and unlock your vehicle, as well as open the trunk and set off the alarm. It is typically made of plastic and has a few buttons on it for various functions.
One way to identify your key fob is to look for the Jeep logo on the front of the device. The logo is usually prominently displayed and can help you distinguish the key fob from other similar devices. Additionally, the key fob may have a serial number or model number printed on the back or side, which can also help you identify it.
If you’re still unsure which device is your key fob, consult your vehicle’s owner’s manual for more information. The manual should have a section dedicated to the key fob and its functions, as well as a picture of what the key fob looks like. This can be especially helpful if you have multiple key fobs for your vehicle and need to figure out which one needs a new battery.
Accessing the Battery Compartment
Accessing the battery compartment of your Jeep Wrangler’s key fob is a simple process that only requires a few basic tools. First, locate the small notch on the side of the key fob. This notch is where you will insert a flathead screwdriver to gently pry open the key fob case. Use caution to avoid damaging the case or the internal components. Once the case is open, carefully remove the old battery from its compartment, taking note of its orientation.
Next, use a cotton swab dipped in rubbing alcohol to clean the inside of the battery compartment, removing any dirt or residue that may have built up over time. This step will help ensure proper contact between the new battery and the key fob’s circuitry. Once the compartment is clean, you can then insert the new battery, making sure to align it correctly according to the markings inside the case. After the new battery is in place, gently press the key fob case back together until it snaps securely into place.
It’s important to always use caution when working with small electronic devices like key fobs, as they can be easily damaged if mishandled. Additionally, be sure to properly dispose of the old battery in accordance with local regulations regarding electronic waste. With the new battery installed and the key fob reassembled, you can now test the key fob to ensure that it is functioning properly. If everything is in working order, you can now confidently use your key fob to unlock and start your Jeep Wrangler without any battery-related issues.
Removing the Old Battery
When it’s time to replace the old battery in your Jeep Wrangler key fob, it’s important to carefully remove the old battery to avoid damaging the key fob. Start by locating the small indentation or slot on the side of the key fob. This is the access point to the battery compartment.
Next, use a small, flat-head screwdriver to gently pry open the key fob. Take care not to apply too much force or you could break the case. Once the key fob is open, locate the old battery. Depending on the model of your key fob, the battery may be easily accessible or it may be held in place with a small clip.
If the battery is held in place with a clip, carefully unhook the clip using the screwdriver. Once the clip is released, carefully remove the old battery from the compartment. It’s important to take note of the orientation of the old battery so you can correctly insert the new battery.

Inserting the New Battery
After successfully identifying the key fob and accessing the battery compartment, the next step in the process of changing the battery in your Jeep Wrangler key fob is inserting the new battery. Once you have removed the old battery and have the new one ready, make sure it is the correct type and size for your key fob. Use the table below to determine the appropriate battery for your specific key fob model.

Once you have confirmed the correct battery type, carefully insert the new battery into the compartment, making sure the positive and negative sides are placed correctly according to the markings inside the key fob. Use your fingers or a small tool to gently press the battery into place, ensuring that it is secure and properly seated.
After the new battery is securely in place, carefully place the cover back onto the key fob and gently press it until it clicks into position. Ensure that the cover is firmly in place to prevent it from coming loose. Once the new battery is inserted and the cover is back on, you can now test the key fob to ensure that it is working correctly.
Testing the Key Fob
Once you have successfully inserted the new battery into your Jeep Wrangler key fob, it is important to test the key fob to ensure that the new battery is working properly. The testing process is simple and will give you peace of mind knowing that your key fob is functioning as it should.
First, stand near your Jeep Wrangler and press the lock button on the key fob. You should hear the doors of your vehicle lock, indicating that the key fob is indeed sending a signal to your car.
Next, press the unlock button on the key fob. Once again, you should hear the doors of your Jeep Wrangler unlock, confirming that the new battery is providing power to the key fob and allowing it to communicate with your vehicle.
