This Stratford Stronghold safe at a bar in Manchester was locked and neither of the keys would open it. We were told that they had always had to jiggle the keys in the lock to get it to work. We picked the lock open and identified that the keys were so badly cut that they had caused the lockout. We provided new keys to the lock which work every time without the need to shake it about in the lock and hope that it opens. If a safe is difficult to open then always get it checked out by a safe engineer before it becomes a major problem.
