Not all locks are created equal. When purchasing entry locks for your home, don’t cheap out. The video below shows how quickly access can be gained via a simple lock pick set on a “standard” entry door lock. Not all locks are created equal they vary in number of pins, strength of materials, resistance to picking, resistance to drilling etc etc etc. The same rule of two is one and one is none when talking about gear applies to home security locks as well. Having just a door knob lock leaves you vulnerable. If you don’t already have a deadbolt as a secondary lock, be sure to install one soon. Adding a third lock such as a swing bar will give you even a bit more protection provided that it is installed with long screws. When shopping for door knob locks and dead bolts to secure your home, be aware that there are 3 grades commonly available, 3 being the least secure and is likely to be made of cheap materials and might use less pins in the cylinder, 2 more secure than 3 and offer some resistance to forced entry by use of stronger materials and additional cylinder pins and 1 obviously is even more secure. Grade 1 locks will usually contain features to make it much more difficult to manipulate, use hardened metals and sometimes even magnets or multiple rows of pins to add to complexity of the lock and make it much harder to pick.
I am certainly not a lock expert by any means, but I tested out a set of Bagota picks on a standard door lock you would find on a steel security door. You can see in the video here that it really isn’t secure at all if someone with little use of a lock pick can gain entry in under 20 seconds.
