People tend to panic when they can’t unlock their cars because their key fob died. But you don’t have to struggle as changing the battery in your car key fob might be easier and cheaper than you think. 

You can change the battery in your car key fob in seconds 

Drivers face car key fob issues every day as people are keeping their cars for much longer than they used to. As a result, the batteries in the fob die, key fobs break, and even go missing. 

Replacing a fob can be expensive, and you don’t have to get a new one if yours dies. You can easily change the battery instead. No trip to the dealership is required. 

Most fobs have a little slot that you can access to pop them open. Tools like a small flathead screwdriver, butter knife, or even another key can be helpful. However, sometimes key fobs can be opened by hand. 

Next, gently pull the two halves apart while being careful not to drip any of the pieces. Then you can remove the old battery. Most key fob batteries are circular and flat. They are typically the size of a quarter or nickel. 

Look at the information on the battery to learn what size and brand it is. Then order a replacement online or see if you can find it at a local convenience store. You can find the batteries for under five bucks in most cases. 

When it’s time to use a new key fob battery, pay attention to how the old one was positioned. Then you’ll know the correct way to place the new one. Last but not least, snap the key fob halves back together and give it a test run. 

Most cars, trucks, and SUVs have smart keys that will last about two to three years. Other regular fobs will last about four to six years. The difference involves different types of frequencies. 

Smart fobs have active receivers that are needed to communicate with your vehicle when it’s near or inside the vehicle. Proximity keyless entry is pretty clutch.
