viper 5704/subaru legacy

One module will help with things like locks door bonnet and hood triggers, indicators etc. so you don't have to hardwire them although IMO not difficult with Japanese vehicles. In other words a convenience module. The second module which is required will be a by-pass module for the immobiliser such as DEI 556U. You could probably get away with just the 556U. Not a difficult vehicle to do. I get the feeling from other posts that Aussies are rushing to fit these products but nobody over there appears to have the technical experience or knowledge to install them. them.

Hey guys, I've got the 556U bypass module and I'm ready to install. The problem I've got now is the Subaru key wont fit inside the module. Is it ok to remove just the transponder chip from the key? Im worried that I might damage it or it wont work without the shaft of the key.

If it's just that the key blade is too long, you could just cut off the blade so it fits in the 556UW.  This would destroy the key but help prevent vehicle theft.

It is possible to extract the transponder chip but requires somewhat delicate surgery.

Soldering is fun!

Here are  photo's of some of the necessary wires found in the BIU :

The Blue/White door trigger should be in that same connector.
