I have a 2005 Aero 8 Series 2 (delivered to US in early 2006). The door lock system does not work (no sound or noise at all coming from the car when you push on the keyless remote). The tech at my local Morgan dealership in Southern Cal has ruled out the following possible causes:

1. Keyless remote fob (new battery installed and fob is working fine)
2. Fuse
3. Relay system (he has already reset the CAN system but this did not solve the problem)
4. Loose wire
5. Loose plug
(Though he did not think that either #4 or #5 above is the reason, he cannot completely rule this out)
6. Faulty module or receiver

He thinks that a faulty module or receiver is the most likely cause for the central door lock system failure and recommended for me to take the car to a local alarm system installer who has never worked on a Morgan before. However, I am trying to find a parts diagram to see where the module or receiver for the central door lock/alarm system is located, but since the alarm system was installed by an outside alarm company that Morgan sourced out to, I cannot find the location of the module/receiver on the online part manual.

Does anybody know or have a parts diagram to pinpoint where the module/receiver for the central door lock system (with keyless remote) is located on a Series 2?
This would allow the local car alarm system installer to know exactly where to go instead of attempting to remove all the panels front and back to try to look for it.

Any help would be appreciated (I am tired of locking the doors manually with the key every time I go out). By the way, does anybody have a similar tissue with the central door lock system on an Aero 8 S2 before?
