A dead key fob battery can be a real pain, leaving you stranded and unable to unlock your car. Luckily, changing the battery in most key fobs is a quick and easy process that can be done at home with just a few simple tools.
This guide will walk you through the steps of how to change a key fob battery, and provide some helpful tips along the way.
What You’ll Need:
Before you begin, gather the following items:
- New key fob battery: Check your owner’s manual or search online to find the correct battery type for your specific make and model.
- Small flat-head screwdriver or a plastic pry tool
- Optional: A small container to keep track of any loose screws
Step-by-Step Guide to Key Fob Battery Replacement:
-
Identify the battery compartment: Most key fobs have a dedicated battery compartment on the back. Look for a small seam, notch, or sliding cover.
-
Open the battery compartment: If your key fob has a release button, press it while gently sliding or prying open the compartment. If there’s no button, use your flat-head screwdriver or plastic pry tool to carefully separate the two halves of the key fob.
-
Remove the old battery: Note the orientation of the positive (+) and negative (-) terminals on the battery. Carefully remove the old battery, using your fingernail or the edge of your screwdriver if needed.
-
Install the new battery: Insert the new battery into the compartment, ensuring that the positive and negative terminals match the orientation of the old battery.
-
Reassemble the key fob: Align the two halves of the key fob and press them together firmly until you hear a click. If your key fob had any screws, reinsert and tighten them now.
-
Test the key fob: Make sure all buttons on the key fob are functioning correctly.
Troubleshooting:
If your key fob still doesn’t work after replacing the battery, here are a few things to check:
- Battery orientation: Ensure the new battery is installed correctly with the positive (+) and negative (-) terminals aligned properly.
- Clean the battery contacts: Over time, the battery contacts can accumulate dirt or corrosion. Gently clean them with a cotton swab and rubbing alcohol.
- Reprogram the key fob: Some vehicles require you to reprogram the key fob after replacing the battery. Consult your owner’s manual for instructions on how to do this.
