The one time my house was broken into, they actually broke down the solid wood door - jamb partly ripped out - cops said it looks like someone went at the door with a crowbar - the then current MO!

They want in bad enough, they will get in. In college, I hung around with a locksmith

2 "Interesting" calls - One was a call - the STEEL door had one of the Medico "drop bolt" locks - no big deal - the theifs took a sawsall to the door!!! The locks were still locked, still hanging there - the Apartment (in Manhattan) was cleaned out

The other? They broke into the apartment next door, and punched a 5 ft tall, 3 ft wide hole through the cinderblock wall between apartments!
