This door lock cylinder turning seems to be a problem experienced by many BMW owners. The repair costs R outrages; costing from $500 to $800 to repair. I believe this is a design flaw by BMW & a recall should be leveled against BMW to correct this problem. My P. Door cannot B opened with the key & the D. Door is starting to work sloppy. So I risk having my car stolen because I don't want to use the locks anymore then I have too.
