Tools and Materials Needed
Before starting, gather the necessary tools and materials:
- CR1620 battery
- Small screwdrivers
- Precision screwdriver or pin
The CR1620 battery is the only type that will fit this key fob. You can find it easily on Amazon or at local stores.
Step 1: Remove the Screw
Start by locating the small Phillips head screw on the back of the key fob. Use a small Phillips head screwdriver to twist out the screw. Set the screw aside safely.
It’s important to use the right size screwdriver to avoid damaging the screw head. If you don’t have one, consider purchasing a small screwdriver set.
Step 2: Open the Key Fob
Next, identify the slot near the top of the key fob. Insert a flathead screwdriver or a precision tool into the slot. Gently twist to open the key fob.
Be careful not to apply too much force, as this could damage the plastic casing.
Step 3: Remove the Old Battery
Inside the key fob, the battery is held securely in place. Locate the small hole in the top corner of the battery compartment. Use a precision screwdriver, pin, or needle to gently pry the battery out.
The battery should come out with minimal force. Dispose of the old battery properly.
Step 4: Insert the New Battery
Take your new CR1620 battery and ensure the positive side is facing up. Slide the battery under the two plastic tabs on one side of the compartment. Then, press down to secure the battery in place.
Make sure the battery is seated correctly to ensure proper functionality.
Step 5: Reassemble the Key Fob
Align the two halves of the key fob and snap them back together. Ensure all edges are flush and there are no gaps.
Reinsert the small screw and twist it back in using the Phillips head screwdriver. Tighten the screw securely, but do not over-tighten.
Step 6: Test the Key Fob
Press any button on the key fob to verify that the battery replacement was successful. The light should turn on, indicating the key fob is working properly.
If the light does not turn on, double-check the battery orientation and ensure it is seated correctly.
