Step-by-Step Battery Replacement
Gather Your Tools
- CR2430 battery
- Flat head screwdriver
Remove the Internal Key
First, flip the key fob over. Locate the switch on the back and hold it down. While holding the switch, pull out the internal key. This step is crucial as it allows you to access the battery compartment.
Open the Key Fob
With the key removed, you’ll notice a small keyhole. You can use the internal key or a flat head screwdriver for this step. Insert the tool slightly into the keyhole and apply gentle pressure to start opening the back of the fob.
Once you see a small opening, use the flat head screwdriver to wiggle your way in. Twist the screwdriver gently until the other side of the key fob starts to come loose. You can then pull the two halves apart with your fingers.
Remove the Old Battery
Now that the key fob is open, locate the battery. Use the flat head screwdriver to gently pry the old battery out from one of the open spaces on the side. Dispose of the old battery properly.
Insert the New Battery
Take your new CR2430 battery. Ensure that the positive side, marked with a plus sign, is facing down. Snap the new battery into place securely.
Reassemble the Key Fob
With the new battery in place, it’s time to reassemble the key fob. Align the two halves of the fob, ensuring the metal switch and the opening at the top are correctly positioned. Push the halves together until they click into place.
Finally, reinsert the internal key into its slot. Your key fob should now be fully functional with a new battery.
