Introdução
If your 2019 Jeep Cherokee Limited key fob is showing signs of a weak or dead battery, this guide will show you how to safely replace it so you don’t have to visit a dealership.
Before starting, inspect your key fob for any cracks or damage. If the fob’s casing is broken or the internal components are damaged, replacing the battery alone may not restore full functionality.
Typically, if the casing is intact, you can easily open the fob, remove the old battery, and install a new one.
Step 2 involves prying the fob open. It’s recommended to use a small flathead screwdriver or plastic pry tool and wear gloves to protect your hands.
For reference, here is a link to a video showing a full key fob teardown and battery replacement for similar Jeep models.
