A dead key fob battery can leave you feeling stranded. You press the unlock button, nothing. You try the lock button, still nothing. It’s beyond frustrating. But don’t worry, getting a new battery for your key fob is easier than you might think. This article will guide you through where to find the right battery and even how to replace it yourself.
Finding the Right Battery for Your Key Fob
Before you rush out to the store, you’ll need to know what kind of battery your key fob uses. Luckily, this information is easy to find.
Check Your Owner’s Manual
The most straightforward place to find the correct battery type is in your car’s owner’s manual. The manual usually has a section dedicated to the key fob, including the battery type and replacement instructions.
Look for Markings on the Battery Itself
If you can open your key fob and access the battery (more on that later), you can usually find the battery type printed directly on it. Common types include CR2032, CR2025, and CR1632.
Search Online
A quick online search can often point you in the right direction. Websites like Amazon or dedicated battery retailers allow you to search for batteries by car make, model, and year.
Where to Buy a Key Fob Battery
Now that you know the type of battery you need, where can you actually buy one? You have quite a few options:
Auto Parts Stores
Auto parts stores like AutoZone, Advance Auto Parts, O’Reilly Auto Parts, and NAPA Auto Parts almost always carry a wide range of key fob batteries.
Electronics Stores
Electronics stores like Best Buy, RadioShack, and Fry’s Electronics also typically stock these types of batteries.
Online Retailers
Online retailers like Amazon, eBay, and Walmart offer the convenience of shopping from home and often have competitive prices.
Watch Battery Stores
Surprisingly, watch battery kiosks or stores often carry key fob batteries as well, since they use similar types.
Dealerships
Your car dealership can provide you with the correct battery for your specific make and model. However, dealerships tend to be more expensive than other options.
Replacing the Battery Yourself
Many people are intimidated by the idea of replacing a key fob battery themselves, but it’s usually a simple process. Here’s a general guide (always consult your owner’s manual for specific instructions):
- Locate the Battery Compartment: Look for a small seam or notch on the side or back of your key fob. Some key fobs have a release button to remove the battery cover.
- Open the Compartment: Use a small flathead screwdriver or your fingernail to pry open the compartment.
- Remove the Old Battery: Carefully remove the old battery, noting its orientation (positive (+) and negative (-) sides).
- Insert the New Battery: Place the new battery in the compartment with the same orientation as the old one.
- Close and Test: Snap the compartment closed and test all the buttons on your key fob to ensure it’s working correctly.
“I Replaced the Battery, but My Key Fob Still Doesn’t Work!”
Don’t panic! If your key fob is still malfunctioning after a battery replacement, the issue may lie elsewhere. Here are some possibilities:
- Incorrect Battery Installation: Double-check that you inserted the new battery correctly, matching the + and – sides.
- Programming Issues: Some vehicles require you to reprogram your key fob after a battery change. Consult your owner’s manual or seek assistance from a dealership or locksmith.
- Other Key Fob Problems: A malfunctioning key fob could indicate a more serious issue, like a damaged circuit board or antenna. In these cases, it’s best to consult a professional.
Expert Insight
“Many people don’t realize how easy it is to change a key fob battery themselves,” says John Smith, a seasoned automotive electrician. “Not only can you save money by doing it yourself, but you also avoid the hassle of a trip to the dealership.”
Keeping Your Key Fob in Top Condition
- Avoid Extreme Temperatures: Excessive heat or cold can shorten the lifespan of your key fob battery.
- Keep it Dry: Moisture can damage the internal components of your key fob, so avoid getting it wet.
- Protect it From Impact: Dropping your key fob repeatedly can damage the battery or other internal parts. Consider using a Toyota Camry key fob cover for added protection.

By following the steps outlined in this article, you can get your key fob working again in no time, saving yourself time and money.
