Car Key Fob Repairs
Key fobs today can do more than unlock and start vehicles. But that extra complexity can cause expensive repair costs in the event that one of them malfunctions.
The good news is that most fobs are equipped with flat-watch-style batteries that are easy to replace at home. And you may find that a reset will make your device work again.
Battery Replacement
A dead battery is the most common cause of a key fob not working. It's a simple fix, and it's worth trying before you spend money on a new key fob. You can purchase the new button cell at a local auto part retailer or hardware store if you have one. You can also refer to your owner's guide (or YouTube for videos explaining how to replace the battery) for specific instructions on how to remove and replace the battery inside your fob.
Most fobs have two halves that snap together -you'll have to gently pry the sides apart to get to the battery. You'll need a small flat-bladed screwdriver, or a different tool with a thin blade. You can put your tool into a slot on the bottom of the key fob. You might also want to keep an eye out for small pieces that may fall off while working.
When you have your new battery, you can insert it in the same manner that you removed the previous one. The positive (+) side should face the buttons and the reverse (-) the markings on the compartment for the battery.
