Tip - Replacing the Battery in Your Car's Keyless Remote

We rely on the remote unlock, lock, and alarm functions on our car or truck key fob, or key chain. This keychain remote has batteries that go dead. If you have a dead or weak battery in your car remote, you will lose range or not be able to use it at all. Replacing your car remote battery is easy. You can replace the battery in 5 minutes or less. We'll show you a Honda remote and a Mercedes Benz remote as examples.
