Imagine: you’re getting ready to drive to work one morning, only to find out that your car key fob doesn’t work anymore. More often than not, this is caused by a dead car key fob battery – something that’s easy to replace. Replacement batteries can be found in many places, including here at Car and Truck Remotes, where we stock high-quality car fob batteries. But how do you remove the old battery, and how do you insert the new one?
How to Replace a Key Fob Battery
- Check the Battery Type
Before you take apart your key fob, you’ll want to check what battery type it uses. Many key fobs will tell you the battery type on the outside so that you can purchase an identical battery as a replacement.
- Locate the Key Fob Seam
Key fobs are composed of two pieces that come together in the middle, so chances are that you’ll find a seam that runs around the edge of your key fob. The battery is located between these two portions. Sometimes, a car key fob will have an access point to help you open the fob; otherwise, you may need a tool like a screwdriver to do so.
- Gently Take Apart the Key Fob
With some car key fobs, you may be able to take them apart using a fingernail. Otherwise, you may need to use a flathead screwdriver to pry the two pieces of the key fob apart at the seams. Hold the key fob in one hand and use a screwdriver to gently open the key fob at the seam – at a certain point, it should pop right open for easy access.
- Locate the Battery Terminals
Car key fob batteries are circular in nature, resembling small coins. These batteries must be placed a particular way for them to work. You don’t want to replace your battery only to find out that you’ve put it in wrong! Note which side faces upwards in your car key fob so that when you replace the battery, you’re placing it back in correctly.
- Remove the Old Battery and Replace It
Your car key fob’s old battery should pop right out due to a spring inside the key fob. If your key fob doesn’t have this spring, the battery can usually be removed with a screwdriver or similar device. Remove the old battery and place the new one in the same position, taking note of the orientation.
6. Reassemble the Key Fob
Once your battery has been placed into the slot, all you need to do is gently put the two pieces back together without the battery coming loose. It should snap together easily! Make sure to test out your key fob to make sure that it’s working.
And that’s all it takes! After following these steps, your key fob should be working like new. Replacing a key fob’s battery is an easy process, and with the right tools, you can have it taken care of in minutes. It’s good to have a couple spare batteries on hand as well to make sure that you’re never stuck out in the cold with a dead remote.
