Is your 2019 Jeep Grand Cherokee key fob acting up? Before you panic and assume the worst, the culprit could simply be a dead key fob battery. This is a common issue and thankfully, it’s an easy fix you can likely tackle yourself. This comprehensive guide will walk you through everything you need to know about the 2019 Jeep Grand Cherokee key fob battery, from identifying the signs of a dying battery to replacing it and even some helpful tips for preventing future issues.
How to Tell if Your Jeep Grand Cherokee Key Fob Battery is Dead
A dying key fob battery can manifest itself in several ways. Here are some telltale signs:
- Decreased Range: Do you find yourself having to stand closer to your Jeep to lock or unlock the doors? A weak battery can significantly reduce the key fob’s signal range.
- Intermittent Functionality: Is your key fob working sporadically? Sometimes it works, and sometimes it doesn’t? This inconsistency is often a clear indicator of a dying battery.
- No Response: The most obvious sign – if your key fob is completely unresponsive, there’s a good chance the battery is entirely drained.
- Dashboard Warning: Some Jeep Grand Cherokee models might display a “Key Fob Battery Low” warning message on the dashboard, giving you a heads-up before the battery completely dies.

The 2019 Jeep Grand Cherokee key fob uses a CR2032 battery, a common type of lithium coin battery. You can readily find these batteries at most auto parts stores, electronics stores, and even some grocery stores.

Replacing the key fob battery is a straightforward process that most people can do at home with just a few simple tools. Here’s a step-by-step guide:

Gather Your Materials: You’ll need a new CR2032 battery and a small flat-head screwdriver or a plastic pry tool.

Test the Key Fob: Try locking and unlocking your Jeep Grand Cherokee using the key fob to confirm the new battery is working correctly.
Tips to Prolong Your Key Fob Battery Life
While key fob batteries are relatively inexpensive and easy to replace, here are a few tips to help extend their lifespan:
-
Avoid Frequent Button Pressing: Repeatedly pressing the buttons, even when out of range, can drain the battery faster. Only press the buttons when necessary.
-
Keep Your Key Fob Dry: Exposure to moisture can corrode the battery contacts and shorten battery life. Store your key fob in a dry place.
-
Don’t Leave Your Key Fob in Extreme Temperatures: Excessive heat or cold can affect battery performance. Avoid leaving your key fob in direct sunlight or freezing temperatures.
