Hi All, I recently noticed that my passenger side lock cylinder (the part where you insert the key to lock/unlock the door) was missing! There is nothing missing from my car at the moment, and thank god I have a clutch lock that I use in my car on. I don't know how they got it off, there are no scratches on the vehicle around the lock cylinder.

Is this something where they steal the lock cylinder and try to make a key copy? And how much does something like that cost to fix? I just found it peculiar that the lock cylinder was missing and nothing else was missing from my car...
