I need to know if I can obtain a replacement alarm button/FOB and how to program the little bugger. Anyone have experience with this?

That may run off the factory keyless. I had one similar to that in my 2000 truck that used the lock/unlock pulses to arm and disarm.

I know the newer gens used the key pulse method to program but I'm not so sure about this old girl. Any idea which factory keyless is compatible? I've done some online searching and there seems to be lots of different options.
