When I went to get spare keys made, the man making the keys seemed to be very familiar with them. He asked me if I was having the keys made so I'd have a backup if my originals bent? When I said yes, he told me that the keys that he's making for me should be better, but because of the length of the key, even they may bend in a stiff lock (like our locks are).HoosierWolf said:This is what I've been doing. Although I'm gaining more trust with the keys I had made.
Agreed the plastic lock mechanism is probably the real issue.
My takeaway from the above was that the problem is the tumblers, but the length of the key apparently doesn't make things any better.
