Remote Start Issue

[TheOriginalEVOTECH]

OK, Here is the deal. I have a tactrix cable that I use for my Evo. My wife has a 2001 Montero that only has 1 key. I want to install a remote starter, but you need 2 keys to do that. So is there a way for me to disable the immobolizer or would it be easier to have another key programmed?
