You don’t need to be a mechanic to tackle this simple task. With a few basic tools and this handy guide, you can save yourself a trip to the dealership and a bit of money.
Identifying the Right Battery for Your Key Fob
Before you start prying open your key fob, you need to know what kind of battery it uses. This information is usually found in your car’s owner’s manual. If you don’t have the manual handy, a quick Google search for your car’s make and model, along with “key fob battery type,” should do the trick.
Car key fobs typically use small, flat batteries like CR2032 or CR2025. These batteries are readily available at most supermarkets, auto parts stores, and online retailers.
Gathering Your Tools
Now that you know which battery you need, let’s gather the tools for the job. You’ll need:
- The new replacement battery: Double-check that you have the correct type.
- A small flathead screwdriver: Or, some key fobs come with a small notch for a coin, so a coin would work as well.
- Optional: A small container or tray to keep the parts organized.
How to Change Your Car Key Fob Battery: A Step-by-Step Guide
Once you have your tools and new battery, follow these steps:
-
Locate the battery compartment: Look for a small seam or groove on the edge of your key fob. This is usually where the battery compartment is located.
-
Open the key fob: Carefully insert the flathead screwdriver (or coin) into the seam and gently pry open the key fob. Be careful not to use too much force, which could damage the fob.
-
Remove the old battery: With the key fob open, you should see the old battery. Note its position and polarity (+/-) for installing the new one correctly. Gently remove the old battery using your fingernail or the screwdriver.
-
Install the new battery: Place the new battery into the compartment, ensuring the polarity matches that of the old battery. Press it firmly into place.
-
Reassemble the key fob: Align the two halves of the key fob and press them together until you hear a click, indicating the fob is securely closed.
-
Test the key fob: Try locking and unlocking your car using the key fob to ensure the new battery is working correctly.
Still Having Trouble?
If you’ve followed these steps and your key fob still isn’t working, there are a few things you can try:
- Check the battery installation: Make sure the battery is properly seated in the compartment and the polarity is correct.
- Try a different battery: Sometimes, even new batteries can be faulty. Try installing a different new battery to rule out this possibility.
- Consult your owner’s manual: Your car’s owner’s manual may have additional troubleshooting tips specific to your key fob.
When to Seek Professional Help
If you’ve exhausted all troubleshooting options and your key fob still isn’t working, it might be time to consult a professional. An automotive locksmith or dealership can diagnose the problem and provide a solution, whether it’s a more complex battery replacement, key fob reprogramming, or a replacement fob altogether.
