The invention relates to a lock assembly with a curved keyway, more particularly to a lock assembly having a lock body with a longitudinal curved keyway and at least two differently oriented sets of tumbler members provided thereon.
The curved keyway removes tumbler members provided on the lock body from straight access which makes actuation or manipulation of the tumbler members more difficult for a thief. The flexible key has a plurality of knuckles hinged to one another.
This would likely confuse the crap out of most lockpickers…
