Experiencing trouble after replacing your 2019 Jeep Cherokee Limited Key Fob Battery? You’re not alone. Many owners encounter a frustrating situation where a fresh battery fails to restore the key fob’s functionality. You might swap in brand new batteries, even multiple times, only to find the fob remains stubbornly unresponsive. Interestingly, putting the old, weak battery back in might just get it working again, highlighting a peculiar issue.
So, what’s the trick to getting your key fob working after a battery replacement? The solution, surprisingly, might involve your vehicle itself. It turns out that for some 2019 Jeep Cherokee Limited models, the key fob needs to be “re-initialized” with the vehicle after a battery change. This process isn’t clearly documented, and even dealership staff may not readily offer this information.
The key to this re-initialization is quite simple: use the fob-on-start-button method, just as you would if your key fob battery was completely dead. Enter your Jeep Cherokee and use your key fob to press the ignition button. This action seems to prompt the vehicle to recognize the new battery and reset any internal memory related to the key fob’s power level. After performing this step, owners have reported that all key fob functions, including remote start, locking, and unlocking, return to normal.
This suggests a possible, undocumented system within the 2019 Jeep Cherokee Limited (and perhaps other models). It’s speculated that either the key fob or the vehicle’s computer tracks battery levels. When a battery is changed, this system might not immediately register the new power source, causing a temporary malfunction. This hidden process can lead to unnecessary dealer visits and potential upselling of new fobs or reprogramming services, which are often not covered under warranty.
While replacing a key fob battery should be a straightforward DIY task, this undocumented quirk can turn it into a headache. Before assuming your new battery is faulty or your key fob is broken, try the fob-on-start-button method. This simple step could save you time, money, and frustration, getting your 2019 Jeep Cherokee Limited key fob working perfectly again.
