Factory keyless entry

Alright so I recently purchased a 98 cherokee sport with the factory fob and keyless entry. There are stickers on the window that say TRIAD security system but it seems like that has been disabled at some point because nothing happens when you hit the truck or while opening the locked door. Anyways I just want to find out if I can install an aftermarket viper alarm that will be able to be controlled by my factory fob? Thanks

Aftermarket alarm controlled by the factory fobs ? Probably not possible. Buy the system you want, and sell the factory system.
