Replacing the battery in your Jeep key fob should be a straightforward task. However, sometimes after you Replace Battery In Jeep Key Fob, you might find that your remote doesn’t work as expected. You’ve put in a fresh battery, but the doors won’t unlock, or the remote start refuses to engage. This can be frustrating, especially when you expect a simple battery swap to solve the problem.
One Jeep owner recently encountered this exact issue. After diligently trying several new batteries to replace battery in jeep key fob, none seemed to work. Strangely, the old, weak battery would still operate the fob, albeit inconsistently. It was only after a bit of experimentation that a peculiar solution was discovered.
The key to getting the new battery to work might not be immediately obvious. The owner found that the newly installed battery only became fully functional after going to their Jeep and using the “fob-on-start-button” method. This is the procedure you typically use when your key fob battery is completely dead – you press the key fob directly against the start button to start the vehicle. After doing this, all the key fob functions returned to normal.
This suggests a possible explanation: Jeep key fobs or the vehicle’s system might have a memory or process that monitors battery levels. When you replace battery in jeep key fob, the system may not immediately recognize the new power level. It’s almost as if the system needs a reset or recalibration to acknowledge the new battery. Interestingly, even dealership staff may not be fully aware of this undocumented quirk.
While many online resources offer advice on how to replace battery in jeep key fob, this particular issue and its solution are less commonly discussed. Dealers might suggest costly solutions like buying a new fob or reprogramming, which may not be necessary. It’s worth trying the fob-on-start-button method first if you encounter issues after a jeep key fob battery replacement.
It’s also worth noting that modern Jeep key fob batteries might not last as long as those in older vehicles. Where a 2002 Chrysler fob battery could last for eight years, a newer Jeep’s battery might only last one to two years. While features like remote start can contribute to battery drain, even regular use of locking and unlocking can impact battery life.
In conclusion, if you replace battery in jeep key fob and experience unexpected issues, try the fob-on-start-button method. This simple step might be the undocumented trick to getting your new key fob battery to work correctly and save you unnecessary trips to the dealership.
