All doors are vulnerable to certain types of attacks but there are some sure fire ways to prevent many techniques.

Glass paneling is one of the main vulnerabilities that a door can have. Do to the fact that a burglar can simply break out one of the glass panels and reach inside and undo the deadbolt and other door locks.  Glass on doors is a big concern, especially if the glass is located within 40 inches or less of the locks.  If the glass is more than 40 inches away from the locks then the concern becomes whether or not the area of opening is big enough for a burglar to crawl through.

Any door that has Glass near the locks should have a double sided deadbolt installed on it. A double sided deadbolt is a dead bolting lock that has a key cylinder on both sides of the door, this insures that no one can reach in through a broken window and unlock the door unless they have a key.

There are some solutions to preventing the glass from being broken out.  For example, 3M makes a film that you can put over the glass itself; thus making the glass more akin to Plexiglas in that it if cracked will remain as one sheet. Another solution is to put metal grills over all of the vulnerable windows. Metal grills use to pose a substantial fire hazard but the new designs actually allow the resident to release the grill from the inside in case of an emergency.

Whatever solution you prefer it is always best to get a professional consult from a security expert such as Sacramento based Roseville Locksmith thus insuring that you don’t take any costly steps that were unneeded.
