i bought a keyless entry alarm by bulldog from jcwhitney for 30 bucks. The only problem I have with it is if you don't set the sensitivity correctly, your alarm will go off when a slight breeze blows through. It took me about 30 minutes to install and you MUST have the haynes manual with the wiring diagram to do it. Other than that it's simple. There's a lot of wires, so if you don't know what you're doing just IM me, I'll help you out. But I think it's a good investment. It's not the best on the market, but hey, it works.
