The problem with all the locks that you can buy at the hardware store is that they are low tech, low quality, mass produced junk that merely gives you the illusion of security. It is our personal belief that you should require a key to open a door. Not a pick, not a screwdriver and certainly not a bump key. Please watch the following videos which are just a small sample of information available on the internet. Do your research and make your own decision. Protect your family and your belongings and outfit your home with a Bowley Lock.
