Upgrading deadbolt - Schlage B62 505 - bump proof?

[cledry]

Why not add an inexpensive restricted keyway and add some security pins. Much less expensive and if they don't have a blank they can't bump it. Most criminals do not pick locks, they break glass or kick things in or use a pry bar.

Here in Denmark its generally advised that you have 2 locks on the main entrance. One with a thumbturn and one with double key access. When you are at home you only lock the thumbturn etc, but use the key to lock both locks when you are not a home. Means you still have an easy exit in case of a fire, as well as not giving a thief/burgular any easy exit when you aren't home.

Double cylinder locks on primary entry doors are illegal in countries that subscribe to the International Building Code.
Even a burglar cannot be locked in.
The onus of responsibility is on the resident/owner to comply with the law. Any emergency that leads to a fatality because of an inescapable door can result in negligent homicide being charged to the perpetrator (home owner/resident or both) and often leads to 25 years to life imprisonment and often civil litigation from the burglars family suing for loss of income. All because you spent a few extra dollars on a double instead of single cylinder deadbolt.

Aside, insurance companies will look for any reason to deny any claim. If you have not obeyed the law in your locality, an insurance company can deny a claim easily and matter of factly. Now, if you have been faithfully paying your insurance for years and your claim is denied....you just wasted all that money on insurance because you wanted a double cylinder lock.

If you have glass near or in the door, do yourself a favor and get security film to toughen the glass. Prevents window smashing and complies with life safety codes/building codes.

Eh, not really. The IBC, for example, is part of Georgia's State Minimum Fire Safety Standards. This standard states:

The governing authority of any municipality or county in this state is authorized to enforce the state minimum fire safety standards on all buildings and structures except one-family and two-family dwellings...

It's always up to the AHJ for what is and isn't enforced, what is and isn't applied, etc.

Doesn't prevent them, just slows them down.
