What You Need to Know About Replacing a Car Key Battery
My car key isn’t working?
Almost every car has a key that allows the car to be operated remotely. This key also serves as the car’s actual key. The car key’s remote control function runs on electricity supplied by a battery, also known as a coin cell battery. This is a small, flat metal disc.
A wireless, electric system like this is really convenient. However, there is one drawback: the battery in your car key can run out. Fortunately, it’s very easy to replace the battery in your car key! We’ve put together a few tips for you.
Where can I get the battery in my car key replaced?
You can usually have the battery in your car key replaced at a car dealership, a specialized locksmith, or even at some auto parts stores.
If your car is still under warranty, you can also contact the dealer where you purchased it; they may be able to help you or
refer you to a suitable service provider. It’s a good idea to call ahead to check whether they have the right battery in stock and whether they can provide the service you need.
Can I replace the battery myself?
Replacing the battery in your car key is usually not a difficult task. There’s a small cover on the back. You can open it—with or without a screwdriver, depending on whether the cover is secured with a screw. This makes it easy to replace the battery, so you can once again unlock your car remotely with ease.
What type of battery is right for my car key?
To determine the correct button cell battery for your car key, you first need to know the make and model of your car key. This information is usually found in the car key’s manual or on the casing itself. Once you know the make and model, you can search online for the specifications of the battery required for your car key.
If you’re not sure, stop by a car dealership or a specialty auto parts store.
Rechargeable button-cell batteries are now available for your car key. That way, you’ll never need new batteries again.
How long does the battery in a car key last?
The battery life of a car key varies and depends on several factors, such as the type of key, how often you use it, and the quality of the battery. Extreme temperatures—both hot and cold—can also shorten the battery life. In general, the batteries in modern car keys typically last between 2 and 5 years.
Check the battery in your car key regularly, and have it replaced as soon as you notice that the key isn’t responding as well as it used to.
Tips for Replacing the Battery in Your Car Key
You’ve already read a few tips in the article. Here’s a quick recap:
Buy the right battery
First, check the type of battery your car key requires. This is often listed in your car’s owner’s manual or on the battery itself. Be sure to purchase a replacement battery of the same type and with the same specifications.
Remove the key housing
Some car keys have a simple way to open the casing, such as pressing a button or unscrewing screws. Use the right tool (sometimes a small screwdriver) to carefully open the casing.
Remove the old battery
Once you’ve opened the case, you can usually easily remove the old battery from the key.
Insert the new battery
Pay close attention to the positive (+) and negative (-) terminals of the battery so that you insert the new battery correctly. Make sure the battery is securely in place.
Close the key housing
After inserting the new battery, carefully close the key housing.
Finally
If you’re having a summer check-up done in preparation for your vacation, it’s a good idea to replace the battery in your car key as well. That way, you’ll be well prepared for your vacation.
