Replacing your key fob battery should be a simple task, right? But for some Jeep Grand Cherokee 2018 owners, it turns into a frustrating ordeal. Discover one user’s experience with a seemingly straightforward battery change that led to multiple failures, dealer visits, and ultimately, an unexpected solution for their 2018 Jeep Grand Cherokee key fob battery problem.
Like many, I thought changing the battery in my Jeep Grand Cherokee 2018 key fob would be a breeze. I was wrong. After installing seven different batteries, both new and used, none of them worked! Each time, I had to resort to putting the old, dying battery back in just to get the key fob to function again. It was perplexing trying to replace the Jeep Grand Cherokee 2018 Key Fob Battery.
Then, I stumbled upon a solution by accident. It turns out, the key fob functions only returned to normal after I went to my vehicle and started it using the fob-on-start-button method – the same method you’d use when the key fob battery is completely dead. After this, everything went back to working as expected. This was the key to solving the Jeep Grand Cherokee 2018 key fob battery issue for me.
This experience leads me to suspect that there’s some undocumented memory or process, either in the key fob or the Jeep itself, that monitors battery levels. When you replace the battery, it might not immediately recognize the new power level in your Jeep Grand Cherokee 2018 key fob. Even the Jeep dealership staff seemed unaware of this, which is concerning when dealing with a Jeep Grand Cherokee 2018 key fob battery replacement.
Instead of offering helpful advice, the dealer’s solution was to sell me a new key fob or a new battery at an exorbitant price, or to reprogram the fob – all at my expense, of course. This experience, unfortunately, reflects a growing trend with manufacturers, not just in the automotive industry, where basic self-maintenance is made difficult and costly. It’s frustrating when dealing with something as simple as a Jeep Grand Cherokee 2018 key fob battery.
It’s also worth noting the battery life difference. In my older 2002 Chrysler vehicle, the key fob battery lasted around 8 years. This Jeep Grand Cherokee 2018 key fob battery, on the other hand, seems to last only 1-2 years. While the older model didn’t have remote start, I used its fob for locking and unlocking regularly. With the Jeep, I sparingly use even basic functions like unlocking due to battery drain, mainly relying on remote start when necessary, which contributes to the quicker drain of the Jeep Grand Cherokee 2018 key fob battery.
In conclusion, replacing the Jeep Grand Cherokee 2018 key fob battery isn’t always straightforward. If you encounter issues after a battery change, try the fob-on-start-button method. This might be the undocumented trick to reset the system when you replace your Jeep Grand Cherokee 2018 key fob battery. And be prepared for potentially unhelpful and costly solutions from dealerships when dealing with seemingly simple problems like a key fob battery replacement on your Jeep Grand Cherokee 2018.
