Hook Locks provide a high level of security against crowbar and screwdriver attacks. They are a good upgrade to the traditional deadlock. Hook locks are designed to throw a hook over into the body, that makes it harder for people to pull the two apart. They are a must have for any van now a days. Not forgetting that here at CC Auto Locksmiths we are a mobile service so we can come to you either at home or at your workplace for added convenience.
