All cars are vulnerable to smart thieves with master keys and hammers.  But yeah, this sorta sucks that a single thump unlocks the door...  That obviously wasn't tested.  They should hire the people that get caught in bait cars to try out pre-release designs.

No tool and nearly no visible damage make for a very easy spontaneous crime. Popping windows and locks gets attention.
