Add on remote start module

[Yanks0114]

After my dad saw my remote start he got real jealous, so for fathers day I want to get him remote start. I want it to intergrate with his factory keyless entry. Its a 2000 GMC Sierra 2500. I konw the range won't be that great but he doesn't want to change the remote. Any idea who makes one like this

A Viper 551t or 551r will do the trick, in order for him to remote start, he will have to hit the lock button twice. The best thing is to transfrer everything on to the new remote .
