Changing the battery in your 2000 Jeep Grand Cherokee key fob should be a simple task, right? However, you might find yourself in a frustrating situation where a brand new battery doesn’t seem to solve the problem. You swap out the old battery, but the key fob remains stubbornly unresponsive. You’re not alone. Many 2000 Jeep Grand Cherokee owners have encountered this peculiar issue.
It turns out, simply replacing the battery might not be enough to get your key fob working again. After trying several new batteries without success, one owner discovered an unusual, yet effective solution. The key? Starting the vehicle using the key fob itself as intended for a dead battery scenario. By pressing the key fob directly onto the start button, a process normally used when the battery is depleted, the key fob miraculously sprang back to life. Suddenly, all functions, from remote start to door locks, were working perfectly again.
This suggests that the 2000 Jeep Grand Cherokee, or perhaps its key fob, has a system that monitors battery levels and might not immediately recognize a new battery upon simple replacement. It’s almost as if there’s a memory needing a reset, and starting the car with the fob in the “dead battery” method triggers this reset. Even dealership staff may not be fully aware of this undocumented quirk. Before spending money on a new key fob or reprogramming services, try this simple starting procedure. It could save you time and money and get your 2000 Jeep Grand Cherokee key fob working again with its new battery.
