Guide overview

Before you begin

This guide shows how to replace the battery in a 2008 Chevrolet Tahoe key fob. The key fob battery supplies power to the remote's internal electronics, which allows you to lock, unlock, and remotely operate your vehicle. However, over time the battery will lose it's energy and it may cause a reduced range, delayed response, or complete failure in operation. If your key fob no longer responds consistently and requires multiple presses on it to function then replacing the battery may restore it to normal.
