Experiencing issues after replacing your key fob battery in your 2015 Jeep Grand Cherokee? It’s a common frustration: you install a fresh battery, but the fob seems dead. You might even try multiple new batteries, only to find your old, weak battery still works while the new ones don’t. This was exactly the problem one Jeep owner faced.
After trying several new and used batteries without success, they discovered a simple yet undocumented solution. The trick? Once you’ve installed the new key fob battery, go to your 2015 Jeep Grand Cherokee and start the vehicle using the fob-on-start-button method – the same procedure you’d use if your key fob battery was completely dead. Surprisingly, this action brought the key fob back to life, and all functions returned to normal.
The reason behind this peculiar fix remains somewhat mysterious. It’s speculated that the 2015 Jeep Grand Cherokee, or perhaps the key fob itself, has a system that tracks battery levels. When a new battery is installed, this system might not immediately recognize the change, leading to the fob malfunction. Starting the car with the fob in contact with the start button could be a way to reset or recalibrate this system, allowing it to acknowledge the new key fob battery.
Interestingly, even Jeep dealership staff didn’t seem to officially recognize this issue or solution. Instead, the dealer offered costly alternatives like a new key fob, overpriced batteries, or reprogramming services – none covered under warranty. This experience highlights a growing concern with manufacturers potentially profiting from basic maintenance issues. While older Chrysler models enjoyed long key fob battery life (around 8 years), newer models like this 2015 Jeep Grand Cherokee might only see 1-2 years, even with conservative use of features like remote start and keyless entry.
If you’re struggling with a new key fob battery in your 2015 Jeep Grand Cherokee, try this start-button trick before resorting to expensive dealership services. It might just save you time and money.
