Remote not Security/Keyless/Starter

Just wondering what was available for this type of application?

Looking for a unit that's sole purpose is to activate add-ons beyond what my current alarm is capable of (1 spare channel)  The more channels the better for the most part I'd like to not have to buy another down the road.  If you know of anybody that makes this I'm not stuck on a brand so as long it works I'll be happy.  I'd like the range to be about that of an average keyless 100-200 feet, but if this isn't an option then I'll take what I can get.  If you know of a thread that covers this and can shoot me a link that'd be great two.  No sense in the info just being retyped over and over .

Thanks in advance,

Jared
