How Keys Work
To be honest I have never spent much time worrying about how keys work but I'm impressed by this animated GIF that explains it so clearly.

And... if you take a good quality drill, (I use a 3mm engineer's cobalt steel one), and drill along the top of the cylinder, where all those pins meet the rotating barrel, hey presto!, the most anti-pick of locks is defeated.
ReplyDeleteThe thing that always amazed me, in the days when more of my job involved locksmithing, was the extent to which nobody took any notice. One job, a woman called me and asked me if I could open her house and fit a new lock, she'd left her bag in a taxi the night before. Had to call her dad and stay at her parents' house.
She'd be home at four, could I please get into the house any way possible, but the lock was very tough and pickproof... And the door had reinforced edges and hinge bolts. But no worry, because her insurance company had said I could smash the door, and they'd pay for me to fit a new one.
So, I turned up and it was a sunny summer afternoon, the neighbours were sitting out in the garden, with the barbecue smoking, and glasses of wine in their hands. Nobody challenged me as I knelt on the step, and tried a set of picks. Nobody questioned me when I drilled the lock and opened the door. By the time the owner came home, I had the new lock fitted, and was looking enviously at the wine.
Locks, for the most part offer an illusory sense of security. Especially as our windows are made of brittle glass.
My husband is a firefighter and often has to enter homes during emergencies. He is reluctant to break down doors and can often gain access by other means.
ReplyDeleteI had forgotten that you had in-house professional expertise.
ReplyDeleteIt highlights the discrepancy we face between our need to be secure, and our need for rescuers to get to us in an emergency.
I doubt that anyone would want my junk. If someone really wanted to get in they would be able to. I can't even keep the mice out never mind a professional thief.
