TRy this: Using the key, does locking and unlocking the driver's door using the blade of the key lock and unlock all the other doors at the same time? I am NOT talking about OPENING the door, but about using the driver's door lock cylinder. From the factory, that driver's door lock is wired to the SKREEM, and the SKREEM then tells the CLP/SSM that an authorized person opened the door. So if the SKREEM is gone, the only way this can work, is if the SKREEM has been replaced by a module that performs this function. Up till LAST WEEK, there was no device that did that, that I know of, until Andre came out with the SKREEMULATOR.

Any way you can get information from a previous owner so you know what you are up against?
