If you own a Hellcat, you know that the key fob is more than just a way to unlock your car. It’s a statement piece, a symbol of power and performance. But like any electronic device, the Hellcat key fob relies on a battery to function. And when that battery starts to die, you may encounter a low key battery warning message on your dash. This article will explore Hellcat key fob battery life, replacement, and some interesting observations about how these keys interact.
One Hellcat owner recently shared their experience with multiple low battery warnings in their key fobs. It began with one key displaying the warning message, while the other seemed fine. After replacing the battery in the first key, the second key began displaying the warning a few days later. Even after replacing the battery in the second key at the dealership during a service visit, a third key (the black valet key) was found to have a dead battery shortly after. This experience raises the question: if one Hellcat key has a low battery, will the others soon follow?
The answer isn’t entirely clear. While there’s no official documentation confirming this behavior, anecdotal evidence suggests there might be a connection. It’s possible that the car’s system communicates with all keys simultaneously, and a low battery in one key could trigger a similar issue in the others. Alternatively, it could simply be a coincidence, with all the batteries reaching the end of their lifespan around the same time.
Regardless of the reason, it’s essential to know how to replace the battery in your Hellcat key fob. The battery type is typically a CR2032, a common button cell battery available at most electronics stores. The replacement process is usually straightforward, involving opening the key fob casing and swapping out the old battery for a new one. You can find videos and instructions online demonstrating the specific steps for your Hellcat model year.
It’s worth noting that a low key fob battery can sometimes cause intermittent issues with locking, unlocking, or starting your Hellcat. If you experience any of these problems, checking the battery in your key fob is a good first step. While the experience of one Hellcat owner doesn’t definitively prove a linked battery life across all keys, it highlights the importance of being prepared. Keeping a spare CR2032 battery on hand can save you time and frustration if you encounter a low battery warning.
