Two things:

1) The CLP/SSM is the same in all Crossfires (SRT/Limited/Coupe/ROadster). But as to taking one from another car, I"m not so sure.
2) Fuse 9 ONLY feeds the ORC, that is, the airbag module, buried in the center console, down under the ashtray/passenger airbag light/cigarette lighter.

Also, lights blink means the SKREEM is good, but not so much the CLP is good. See below for what module drives what lights. The PDF goes into it a bit more. Section 4 explains how the flashing of all the lights work.
I cant see how the antitheft sensor can blow that fuse. I'm just wondering if the CLP/SSM you have is really compatible. Sorry, but I"ve never taken one from an SLK and I don't know of anyone who has.
I have fixed three convertible tops that did not work by putting in a replacement CLP/SSM from parts cars - but never used an SLK version.
