Door locks provide the first line of defense against theft in any home or business. Nothing is more important than making sure property and occupants are safe from those who do harm. Consumers have choices when securing a house or office and it pays to research the various locking mechanisms available before making a final decision about what to buy and install.

No single locking mechanism is guaranteed to keep out one hundred percent of intruders but installing a good lock will be an effective deterrent and greatly reduce the risk of a security breach. Locking mechanisms are made in a wide variety of styles and each has its own unique set of characteristics to analyze and consider.

The spring latch lock is the most affordable and easy enough for almost anyone to install. At the same time, it is the most vulnerable and provides the least amount of security to the user. This device locks the doorknob and prevents release of the latch which is spring-loaded inside the door frame. A key is used to release the latch and allow the user to turn the knob.

A spring latch lock does has its disadvantages. A device other than the key, in the hand of someone who knows what they are doing, may be used to release the bolt and allow access. A heavy tool like a hammer can be used to physically breach the doorknob and lock unless a metal plate is installed to reinforce the wood.

Deadbolt locks offer a higher level of security and are recommended for exterior doors. A key is used to slide the bolt into the jamb from the outside while a knob is used to lock the device from the inside. Preferred materials are bronze, brass or solid steel.

A horizontal deadbolt is vulnerable if an intruder is strong enough to pry the door away from the jamb. One way to avoid this is to install a surface-mounted, or vertical, deadbolt. Cast metal rings inside the frame surround the throw and make this type of lock virtually impossible to pry apart.

Keyless locks represent the latest in safety technology. These devices offer quick access to the home without having to fumble around with a traditional key. A keypad design requires the user to program in a special code. Some locks are activated with a remote control unit similar to those used for automobiles.

A biometric lock is an even more sophisticated keyless system. This device is designed to scan and recognize fingerprints and is very hard to beat. It can be programmed for multiple users and is often used in large companies where it is necessary to restrict access to sensitive areas.

Consumers are urged to review the various types of door locks on the market and consider their own specific needs. Locking mechanisms come in a wide range of styles for those who are interested in preserving the aesthetics of any home or office building. Regardless of need, there are suitable systems to effectively secure any property.
