Hes probably left a plug loose on the back of the module. It's a fiddly little thing to get your hands up the back of

So the module contains the imboliser key code. Probably why it doesn't start.
Do all the other electrics work ok ?

It maybe worth a punt buying an autel ap200 white from £45 and seeing if that will program your new key. Some require a working key to start with though.

As said, check the rear of the cjb with a mirror, if you can see red on any of the plugs, they are not fully in
