Car Alarm (clifford, compustar, bypass)

[deicustoms1]

First, is there 2 different types of PassLock on the h3s, anti-theft and content theft? I don't have a chip or anything in my key, but I still need a bypass correct?

The info for the h3 off of directwire says to use the 556LW, I've read on here to use the 556L, is there a difference?

And, has anyone used the Compustar 2WSS-AS? I'm curious if the remote is easy to use and the buttons aren't easily accidentally pressed.

I'm either going with that compustar one, or a clifford matrix rsx 3.5, does anyone know if I can just hook up that alarm (which is also remote start), without installing the remote start on that model (compustar model too)? I'm not sure I want that right now, but if I change my mind in the future it would be nice to be able to do it. thanks.
