Is your Key Fob dead? This is How to Unlock and Start Your Key Fob (6 Steps).

There are two batteries inside the key fob to allow it function correctly. You should replace the batteries before you attempt to drive. You may not realize that replacing batteries isn't always as simple as people think.

To replace key fobs, you simply need to take off a cover on many of them. These covers can be purchased at most supermarkets or gas stations. If you have any questions, consult the manual or search online for information. You can also try to hold your car key very close to the car door when trying to unlock it – to try to get a small signal, which may be enough to unlock the car.

You should not replace your batteries if you're stranded.
