I lost my factory wheel lock last fall. I've since tried 3 of these replacement wheel lock keys with minimal success. In fact, the metal inside the key that forms the pattern of the lock seems too soft. With hand tools I can remove a wheel lock with a key. When I get to the other wheel, it turns out that the metal has warped due to the loosening of the locking lug and the key no longer grips the lug. I wouldn't risk trusting this wrench to replace a flat tire.
