Your car’s remote key fob is an essential part of your daily routine.

Step-by-Step Guide on How to Change the Battery in Your Car Remote
Step 1: Identify the Type of Remote Key Fob You Have
Car remote key fobs come in various designs and types, but they all function the same way. Some are simple, while others are more advanced with buttons for additional features like remote start or trunk release. To ensure you get the correct replacement battery, check your car’s manual for battery specifications or take a look at the current battery inside the fob.
Step 2: Open the Car Remote Key Fob
To replace the battery, you need to access the inside of the key fob. Here’s how:
- Locate the seam where the two halves of the key fob meet. This is usually along the side.
- Use a small flathead screwdriver to gently pry open the key fob. Be careful to not use too much force to avoid damaging the case.
- If your remote has a screw, you will need to use a small screwdriver to remove it before opening the fob.
Step 3: Remove the Old Battery
- Take note of the battery orientation (which way it faces). This is very important when installing the new one.
- Remove the old battery using your fingers or a small set of tweezers. Be cautious not to damage any of the fob’s internal components.
- Dispose of the old battery properly according to your local regulations.
Step 4: Insert the New Battery
- Take the new battery and place it in the same orientation as the old one. The flat side (with the writing) usually faces upward.
- Make sure the battery sits snugly in place and doesn’t move around.
Step 5: Close the Key Fob
- Once the new battery is in place, carefully snap the two halves of the fob back together.
- If there’s a screw, screw it back in place to secure the fob.
- Make sure it’s closed tightly and there are no gaps.
Step 6: Test the Remote
After the key fob is back together, test the remote to make sure it’s working. Try pressing the buttons to check if the car doors unlock, the trunk opens, or any other functions work. If everything is functioning correctly, you’re done!
Tips for Maintaining Your Car Remote Key Fob
- Avoid water exposure: Car key fobs are designed to be durable, but they aren’t waterproof. Keep your key fob dry to extend its lifespan.
- Check for wear and tear: If the buttons on your key fob start to wear out, or if the fob itself looks cracked, it may be time to get a new one.
- Store your spare key properly: If you have a spare remote, store it in a safe place and keep it away from extreme temperatures.
