Can any 1 help me I've changed my ccm unit for 1 with remote locking I've got the key that is paired to the unit it all worked fine in the other car but I can't seem to get it to work on my other fabia I've tried pairing it  and still nothing everything I needed I have changed the come from the old fabia can any 1 help me or Point me in the right direction how to get it to work 

Also if this affects anything I have no immobiliser on ecu or clocks 

What does the unit that you've changed look like?

It's the same ccm unit just with remote key on it 

Reason I ask is that there are two units both of which get called CCM by some people, but only one of them has anything to do with the locking system. The  correct one lives high above the clutch pedal, with a single connector? The other unit has loads of connectors and sits above the accelerator pedal. (Assuming your car is RHD)
