SLK/R170: car wont lock!
My particular experience may be different, but if I cracked a door or the trunk, it would lock... but if that door or trunk was closed immediately after, they would re-unlock... if i waited a minute it would not re-unlock...
not really worth spending a lot of effort wondering 'why', either dry out the module and remove corrosion, or get new/used module. There are plenty of threads on the subject.
