Can't imagine this lock being worth anything if it has a standard pickable key access.
I use
Medeco locks, almost unpickable, and cannot be duplicated except where you bought it (with strict controls). Ridges are cut at angles. Failing to pick my locks might encourage intruders to seek a softer target. I also put them in because a good friend of mine was very, very good at picking locks. Engineer. Sadly, he has passed, far too early.
From their site:
• Every 13 seconds a home is burglarized;
• In more than 50 percent of all residential burglaries, entry is gained through a door;
• More than 85 percent of break-ins are committed by non-professional burglars, who are usually desperate and dangerous individuals;
• Fifty percent of all burglaries occur during the day.
