I was reading about lock "bumping" where burglars buy 'bump' keys and can open locks very quickly. I was also reading that some locks are bump proof (double chamber perhaps?). My question is: how can I tell, by looking at the locks currently on my door, if they are bump proof or not?
I don't see any brand or manufacturer name on the locks but they were replaced 3 months ago when we bought the house.
If you are not familiar with bump keys or locks take a look at this video: http://www.youtube.com/watch?v=hr23tpWX8lM
