How often are you asked by customers "So what lock do you use?". My heart sinks everytime I'm asked this, as you know that they are really wanting a recommendation on what to buy.
I start off by explaining there are some very expensive high-security locks that they might not know about. The price usually puts them off though. I then explain that most robbers are not going to pick their locks, but just break something wooden to get in, like a door or window frame.
Fortunately local knowledge comes in handy here - Disk detention locks are not very well known locally and the round key with funny angles cut on it seems to impress people, so I sell a 75mm version of one of them. The lock "looks hard" and with the unusual keyway, it seems to be more than enough (at least at the moment) to put thieves off trying to get in through the lock.
How do others answer THAT question though?
