This is a case for an impressioning attack...
From "Keys to the Kingdom" by Deviant Ollam:
"The use of thin pieces of metal foil in conjunction with specially-prepared keys can sometimes achieve the same effect as conventional impressioning methods. By applying tension to a lock cylinder, and thus causing pins to bind, it is possible to wiggle a key and cause these binding pins to rub. ...
...The technician also has no need to shave metal from the key by filing with hand tools. The use of a malleable medium, such as foil, will cause the key to deform at the point where it rubs against a binding pin. Repeated wiggling and oscillating of the key can result in small depressions in the foil or other soft medium, thus allowing the lock to be opened rapidly… sometimes in seconds...
...In particular, locks that operate using dimple keys are especially suited to this tactic..."
It works...
