Home security systems have become a big business in recent years. But for many homeowners, strong door locks and deadbolts still provide the first line of defense against a home invasion or burglary.
A solid locking system on doors provides a solid deterrent for many burglars. The Home Safety Council offers the following sampling of key lock types that can be used to protect a home:
Lock/knob assemblies (locksets): Often the most simple, yet least effective lock. These are included as part of the doorknob assembly. A "privacy lock" has a lock on the inside knob only and is usually used on bathroom or bedroom doors. A "key-in-the-knob" lock comes equipped with a key slot on the outside knob and a button or "thumb turn" on the inside. "Locksets" consist of knobs or handles, a latch bolt assembly and any associated trim.
Surface mount, rim mount or vertical deadbolt lock: Three forms of a single type of lock which bolts flush against the inside face of the door. Vertical bolts from the lock slide up and down through a strike attached to the doorframe. This is the most easily installed type of supplemental security lock.
Internal deadbolt lock: An inexpensive supplement to key-in-knob locks. The best deadbolts have at least a 1-inch bolt with a hacksaw resistant steel pin. They are mounted inside the door and can be installed easily using a template provided by the lock manufacturer.
Mortise lock: These locks have both a deadbolt and latch bolt in a single assembly, and come complete with knobs or handles. Because of the need for precisely mortising the slot for these types of locks, professional installation is usually recommended.
