Hellfire is no longer in the aftermarket alarm business, so all keyfobs for Hellfire systems are no longer made. However, Remotes Unlimited does have a limited stock left of some Hellfire remotes. Many Hellfire remotes look very similar, so, the best way to shop for your part is by the manufacturer’s part number on the remote or system. This number starts with “AC” followed by 4 digits and sometimes another letter at the end.
Here is a link to the remote with Hellfire part number AC4084.
