Experiencing trouble after replacing your 2009 Jeep Grand Cherokee Key Fob Battery? You’re not alone. Many owners encounter a perplexing situation where a fresh battery doesn’t immediately solve the problem. You might find yourself inserting brand new batteries only to have your key fob remain unresponsive. Interestingly, putting the old, seemingly dead battery back in might temporarily restore functionality, highlighting that the issue isn’t always straightforward battery depletion.
One user discovered a workaround that might seem counterintuitive but proves effective. After struggling with multiple new batteries that failed to operate their 2009 Jeep Grand Cherokee key fob, they found success by using the “fob-on-start-button” method. This is the procedure typically used when your key fob battery is genuinely dead. By going to the vehicle and starting it by pressing the key fob directly against the start button, the key fob functions miraculously returned to normal. All remote functions, like locking, unlocking, and remote start, were restored.
This suggests a possible, undocumented feature or process within the 2009 Jeep Grand Cherokee’s system – perhaps in the fob itself or the vehicle’s computer. It’s speculated that the system might monitor battery levels and fail to recognize a newly installed battery with a full charge. This theory is further supported by the fact that even dealership staff might not be officially aware of this quirk.
Facing this issue can be frustrating, especially when dealerships offer costly solutions like new key fobs, battery replacements at inflated prices, or reprogramming services not covered under warranty. It’s a sentiment shared by many vehicle owners who feel pressured to spend unnecessarily on basic maintenance. While older Chrysler models seemed to have longer-lasting key fob batteries, newer Jeep models, even with less frequent remote function usage (excluding remote start), appear to require more frequent battery changes.
If you are facing a similar issue with your 2009 Jeep Grand Cherokee key fob after a battery replacement, try the fob-on-start-button method. It might be the simple, no-cost solution you need to get your key fob working again. This simple trick could save you time and money, bypassing potentially unnecessary dealership visits and expenses.
