viper 5101 addons

I have a viper 5101 System. I'm looking for a few add ons/ tweaks. 1. two way remote upgrade? is this possible to do just by buying and pairing a 2 way remote from a 5701? 2. power window roll up as doors are locked. 3. timed door lock after walking away from the car? incase of accidentally leaving doors unlocked. does anyone have a 5701 remote? Do they like it as opposed to a 1 way remote? or is it pointless? I heard the power windows can be done with a 10 second relay bought on ebay? A one touch for all four windows to go up or down would be really nice. I thought the timed door lock came built into the system. I don't think it happens in my vehicle. Thanks guys

Mostly no, what vehicle?

1 NO 2 You will need either a 530t per pair of windows for closing and venting or a 529t for simply close on lock. Simply using relays will very quickly burn out your window motors. 3 Passive arm and lock on your units programming, boy are you ever going to regret doing it the first time you leave the key in the car.
