Wj The "LAST", remote start install into a WJ, thread!

Hey first post here just so I can get this question answered. I need to know if I need JUST the DEI 455J transponder unit to put my Compustar remote start into my 99 WJ limited. It has the Sentry Key so I know I need to get around the SKIM but just can't find out enough about this DEI 455J to answer my own question. Do I need another bypass unit on top of the 455J or not?

I'm in the midst of installing a Viper 5701 in my '03 Overland. The 455J is not a transponder bypass kit; it is a door lock interface kit that eliminates the need to use additional relays and diodes to control the door locks and dome light illumination. If you plan on using the 455J (door lock interface kit) then you also need the 556U (transponder bypass kit). The 556U requires an additional key which is stored in the module, and when you remote start it looks at that module for the key.

There are all-in-one kits that control your door locks and bypass the transponder system, such as the XK531 (which I think is discontinued but I'm sure there is a replacement available). Not too sure on the all-in-one modules since I ended up going for the 455J and 556U. Hope this helps.
