Introduction
This guide will show you how to replace a battery in a car FOB, which is needed to unlock/lock your vehicle and easily access it. There is also a remote start feature on the FOB, so fixing it benefits the user in many ways. Fixing the FOB is safe and easy, there is no safety risk involved. The only requirement for this fix is purchasing new batteries, which can be found in any drug store for a very inexpensive price.
