Experiencing trouble with your key fob after replacing the battery in your 2014 Jeep Grand Cherokee? You’re not alone. Many owners find that simply swapping out the old battery for a new one doesn’t always solve the problem. Sometimes, even with a fresh battery, the key fob refuses to work, leaving you scratching your head.
It can be frustrating to encounter issues even after a seemingly straightforward key fob battery replacement. You might try multiple new batteries, only to find your old, weak battery still operates the system while the new ones don’t seem to register. One Jeep Grand Cherokee owner discovered a peculiar, yet effective solution: using the fob-on-start-button method.
The solution that worked for this owner was surprisingly simple. After installing the new key fob battery, instead of immediately testing the remote functions, they went to their 2014 Jeep Grand Cherokee and started the vehicle by pressing the key fob directly against the start button. This is the same method used when the key fob battery is completely dead. After starting the vehicle this way, all key fob functions reportedly returned to normal.
This suggests that there might be an undocumented process or memory within the 2014 Jeep Grand Cherokee’s system, or perhaps in the key fob itself, that monitors battery levels. When a new battery is installed, the system may not immediately recognize the change in power. Using the fob-on-start-button method might trigger a reset or recalibration, allowing the system to acknowledge the new battery. Even dealership staff might not be fully aware of this undocumented quirk.
Facing this issue, the owner was offered costly solutions by the dealer, such as a new key fob, an overpriced battery, or fob reprogramming – none of which were covered under warranty. This experience highlights a common frustration with modern vehicle servicing, where basic maintenance can become unnecessarily complicated and expensive. While older vehicles like a 2002 Chrysler might have key fob batteries lasting for many years, newer models like the 2014 Jeep Grand Cherokee may require more frequent battery changes, sometimes as often as every 1-2 years.
If you’re struggling with a new key fob battery in your 2014 Jeep Grand Cherokee, try the fob-on-start-button method. It might just be the undocumented trick to get your key fob working again and save you a trip to the dealer.
