Scanners work in OBD mode but when I give it the car specific it goes for a few minutes and fails with "communications failure". Two different professional level scanners. Tried to find PO but is in Georgia and no success so far. Seems to have come from a Georgia auction last June. Started out as a great deal and am finding out why. Still good and in the right place since can compare to SLK320, electrically is the same. Concened that the red thingie does not flash and spare key does not seem to be a chip key (wondering where my chip reader is). Can you see the SKREEM from underneath with the panel removed ?
Sounds like a skreem delete was done. You can only see it if the cluster is removed. It is possible neither of your keys have transponders either. It is possible you might just need to plug back one cable to the skreem to make the keyfobs work, it is mentioned on another thread which cable (assuming skreem delete).
Most scanners cannot read it as a Crossfire only SLK320. You can try scanning it as a 2007 or 2008 Crossfire, sometimes that works.
When using the key in cylinder, it should lock both doors and trunk.
