2002-2006 Toyota Camry Key Fob Battery Replacement (2002, 2003, 2004, 2005, 2006)

Introduction

This guide goes step-by-step on how to replace your fob battery for a 2002-2006 Toyota Camry. A key fob (or simply fob) is a small security device that is usually used to lock and unlock doors. A fob is an electronic device and like all electronic devices, it requires a power source. The power source for a fob is the battery. After some amount of time, you may notice that the range at which the fob works is less than what it used to be or that it sometimes is not locking/unlocking your vehicle at all. Often this is caused by a battery that is dead or almost dead. Replacing a dead battery should return the fob’s function. Replacing the battery in the fob requires no specific skills and no tools are required. The only required materials are a lithium coin battery. If you are having difficulty separating the two pieces of the fob from each other, a spudger could be used to help.
