Step 1: Opening the Key Fob
Start by pressing the button to release the internal key from the key fob. Then, locate the keyhole and a small slot next to it. Insert a flathead screwdriver into the slot and twist to separate the two halves of the key fob.
Step 2: Removing the Old Battery
Inside the key fob, you’ll find the old battery housed in its compartment. Use a precision screwdriver (or a similar tool like a toothpick) to pry the old battery out. Be sure to target the top right area and wiggle the tool underneath the battery to pop it out.
Step 3: Installing the New Battery
Get a new CR2032 battery and insert it into the housing with the positive side facing down. Position the battery by pushing the bottom into the metal component and then press on the top to ensure it sits flush into place.
Step 4: Reassembling the Key Fob
Reconnect the two halves of the key fob by clicking them back together. If the battery has remaining power, the key fob should come back on, indicating that the replacement was successful.
