Step-by-Step Instructions
Step 1: Remove the Internal Key
First, locate the small switch on the bottom of the key fob. Hold this switch down and pull out the internal key. This step is crucial as it gives you access to the inside of the key fob.
Step 2: Open the Key Fob
With the internal key removed, you’ll notice a larger hole, which is the keyhole. Perpendicular to the keyhole is a smaller slot. Insert a flathead screwdriver into this slot. Twist gently to crack open the key fob. Don’t worry about damaging it; the process requires minimal force.
Step 3: Remove the Battery Housing
Once the key fob is open, flip it over to dump out the component that houses the battery. Set this component aside for now.
Step 4: Pry Out the Old Battery
Look for a small indentation in the corner of the battery housing. Insert a flathead or precision screwdriver into this indentation to pry the battery up. You can also use a paper clip, toothpick, or bobby pin. Be gentle to avoid scratching the housing.
Step 5: Insert the New Battery
Take your new CR2032 battery and ensure the positive side is facing up. Click the battery into place, making sure it sits securely in the housing.
Step 6: Reassemble the Key Fob
Place the battery housing back into the key fob. Align the pieces and click them back together. Insert the internal key back into its slot.
Step 7: Test the Key Fob
After reassembling, check if the key fob is working. Press any button and look for the light to come on. If the light illuminates, you’ve successfully replaced the battery.

Common Issues and Solutions
Key Fob Not Opening
If you’re having trouble opening the key fob, make sure you’re inserting the screwdriver into the correct slot. Applying gentle pressure should do the trick. If it still won’t open, try using a different flathead screwdriver.
Battery Not Coming Out
For a stubborn battery, use a smaller tool like a precision screwdriver or a paper clip. Be patient and avoid forcing the battery out, as this could damage the housing.
Key Fob Not Working After Replacement
If the key fob doesn’t work after replacing the battery, double-check that the battery is inserted with the positive side facing up. Ensure all components are aligned correctly before snapping the key fob back together.
