Have you just replaced the battery in your 2020 Jeep Grand Cherokee key fob, only to find it’s still not working? It’s a common frustration – you install a fresh battery, but the fob seems unresponsive. Before you assume there’s a bigger problem or head to the dealership, there’s a surprisingly simple solution you should try.
Many 2020 Jeep Grand Cherokee owners have encountered a peculiar issue: after replacing the key fob battery, the fob doesn’t immediately regain its functionality. You might try multiple new batteries, thinking you’ve bought duds, but still face the same problem. Interestingly, putting the old, weak battery back in might even restore some function temporarily, adding to the confusion.
The solution, often overlooked even by dealership staff, involves a simple reset process. It appears that the Jeep’s system, or perhaps the key fob itself, doesn’t automatically recognize the new battery’s power level. To rectify this, you need to manually initiate a recognition or reset process.
Here’s the simple step-by-step solution to try:
- Enter your 2020 Jeep Grand Cherokee.
- Take your key fob and press the start/stop button with the fob itself. This is the same method you’d use if your key fob battery was completely dead.
- Start your vehicle while pressing the start button with the fob.
This action often triggers the system to recognize the new battery. After starting your Jeep using this method, your key fob should return to normal operation, with all functions like remote start, locking/unlocking, and panic button working as expected.
It’s speculated that this issue arises from a memory or tracking system within the fob or vehicle that monitors battery levels. When a new battery is installed, this system might not immediately register the change, causing the fob to remain inactive. The fob-on-start-button method likely serves as an undocumented reset procedure, forcing the system to acknowledge the new power source.
Dealerships might not always be aware of this simple fix, sometimes leading them to suggest more expensive solutions like buying a new key fob or reprogramming. Before considering these options, trying this battery reset method can save you time and money. It’s a quick and easy troubleshooting step for your 2020 Jeep Grand Cherokee Key Fob Battery issue.
While older Chrysler models might have had key fob batteries that lasted for many years, newer models like the 2020 Jeep Grand Cherokee might require more frequent battery changes, especially with features like remote start in regular use. Keeping this simple reset trick in mind can make future battery replacements much smoother.
