The most common type of lock is the original combination lock. <a onClick=”javascript:pageTracker._trackPageview(‘/outgoing/article_exit_link’);” href=”http://www.24-Hours-Locksmith.com”>Combination locks</a> are very simple to use, usually including a number or symbol sequence to unlock the code. The first lock of sorts was created in the 13th century by an Arab inventor and engineer. There are two common types of combination locks in circulation of every day use, multiple-dial locks and single-dial locks.

Multiple-dial locks are one of the simplest types of combination locks, often seen on low-security bicycle locks and briefcases. It is described as using several rotating discs with notches cut into them. The lock is secured by a pin with several teeth on it which hook into the rotating discs. When the notches in the discs align with the teeth on the pin, the lock can be opened. The simplicity of this lock has considered it to be the least secure of all lock variations because most locks do not require the exact combination to open.

Single-dial locks are combination locks normally found on padlocks or safes which may use a single dial which interacts with several parallel discs. Single-dial locks are also common on school and gymnasium lockers. In most cases, this type of lock is opened by rotating the dial clockwise to the first numeral, counterclockwise to the second, and so on in an alternating fashion until the last numeral is reached; when the correct combination is entered, the notches align, allowing the latch to fit into them and open the lock. Depending on the quality of the lock, some single-dial combination locks can also be defeated relatively easily. Yet, this is still significantly better security than multiple-dial locks and many keyed locks, but unacceptable for high security applications.

Despite the simple nature in the name of a combination lock, figuring out the combination is only the first step in breaking the code because both types require the correct variation in the entry of the numbers or symbols.

A number of factors need to be taken into consideration when purchasing locks for commercial facilities: security requirements, ADA compliance, how often the lock will be used, and the type of room being secured. From the front door to the storage closets, each application requires careful consideration in lock selection.

Most commercial buildings, from warehouses to schools, rely on a mixture of lever locks, deadlocks and mortise locks. Each type of lock normally is available in standard, medium and heavy duty construction. Standard duty locks are suitable for privacy locks, patio locks, classrooms and storerooms. Medium duty locks are suitable for office doors, passageways and classrooms. Heavy duty locks are suitable for entry doors, apartments and offices. When choosing a lock, consider how secure the door needs to be–heavy duty locks provide more security than standard duty locks.

Study the lock construction to determine if it’s going to do the job. For example, in choosing a heavy duty cylindrical lever lock, look for the following specifications: 1) Meets ANSI/BHMA A156.2, Series 4000, Grade 1 for key-in-lever locksets; 2) Allen-head screws are used on the inside levers to prevent vandalism; 3) Lever is free-wheeling when the outside lever is locked; 4) Meets requirements of the Americans with Disabilities Act of 1991; and 5) Cylinder assemblies are removable in case the lock ever needs to be rekeyed.

Decide if you can use a mortise lock or need to install a deadlock paired with a cylindrical lock. A mortise lock provides ease of entry since the lever will open the door after the top locking mechanism is unlocked. A deadlock/cylindrical lock combination requires unlocking both the deadlock and the lever lock but provides more security.

Consider having a special coating added to lock levers installed on doors leading to rooms containing hazardous materials. The rough sensation of the abrasive coating alerts anyone opening the door to the potential dangers on the other side.

Added security can be found in electrified door locks. The best locks offer either a “fail safe” or “fail secure’ option. A fail safe latch bolt can be operated by the lever from either side except when the outer lever is electrically locked, then neither lever opens the door. By contrast, on a fail secure lever the deadlock latch bolt can be operated by the inside lever at all times, only the outside lever is inoperable when the latch is electrically locked.

The best lock suppliers will offer locks for every need, including asylum locks, dormitory locks and closet locks. Expect to pay from $40 for a basic lock up to $300 for the most secure locks.

Combination locks are the most common type of lock around for smaller objects. It usually consists of a sequence of symbols and numbers. These locks have been around since the thirteenth century. The lock has a pin and each number from the combination releases a piece of the puzzle so to speak. Combination locks are a little more complicated when it comes to cracking the code.

Moms and Dads have been losing the curfew argument for years!

Whether you are looking to secure your home or your office, a Schlage entry lock is a good choice for security. You want something that is sturdy, long lasting and still good looking. There are, of course, a number of locks on the market, but if you want to be sure that you are getting the best, you should look at Dexter locks, which are also made by Schlage. The Schlage entry lock is just one of many types of locks offered by the professional security company. They have an offshoot business under the name of Dexter locks, which are also of top quality. These deadbolt locks can help prevent theft. Home invasions are scary for everyone who is a victim of one. If you are there when the burglary takes place, it is entirely possible that you or a family member will be injured, but even if you aren’t there or even if the burglary takes place at your office, you will find that it is still nerve wracking. Having someone break into your personal space can make you feel insecure and violated and, unfortunately, those feelings tend persist for a long time. Ensuring that your home and office are as secure as possible can help you recover from a theft, but it’s far better to prevent one in the first place. Dexter by Schlage is a solid, long-lasting lock that you can trust to ensure entry security. If you don’t trust the current locks in your doors, it’s a good idea to select new ones which will give you the sense of security that you need. What Makes a Schlage Entry Lock Secure? Entry security is important, but most locks aren’t built to really withstand much in the way of pressure. Schlage entry locks are built out of stronger metal that will resist saws and other tools that may be used in an attempt to compromise the lock. They are also designed to be useless with lockpicking tools, which is what many burglars use. A Dexter lock is designed with the Schlage ideals, built to be strong, but also built elegant enough that you would be thrilled to have these locks in your home or office. They come in a range of styles, with a variety of finishes to choose from, meaning that you are bound to find something that matches your style or even existing hardware in your home or office. Selecting the right lock, such as Dexter by Schlage, is vital in protecting your home and family. Remember that most burglars are already experienced. They aren’t going to spend a lot of time trying to get into a well-secured home, not when they can simply pop the lock in the next house. By using a strong lock, you can deter any would-be burglars. Many people don’t realize that thieves are lazy and will stick to easy pickings. Your entry security should be the best possible. While you need to protect windows or any other possible entry points, the fact is that the entrance is the first place that most burglars will go to. With home and office invasions occurring more and more often, now is the best time to start thinking about putting in better locks. When choosing a good entry security system, you should certainly consider Dexter locks, which are similar in design to Schlage entry locks. They offer the best security against kick ins, lock picking and cutting tools, which means your doors will be safer than ever before. The added advantage of Dexter by Schlage is that you can order them online making it extremely easy to get new locks for your entire home and your office, no matter how busy you are.

No business is immune to crimes like break-and-enters.

Cylindrical locks are an affordable lock solution for many commercial applications. Installation is less labor-intensive than installing a mortise lock. In addition, the locks are easily re-keyed or replaced when necessary, usually without needing to call a locksmith. Commercial cylindrical locks are available in a variety of finishes and in standard duty, medium duty and heavy duty construction.

Construction and reliability are the main considerations when choosing cylindrical locks. Schlage and Falcon are two of the best known lock manufacturers. Consumers can always expect to get the finest quality locks when purchasing from one of these companies. In fact, it was Walter Schlage who invented the cylindrical lock in 1909.

Look for the following specifications when shopping for cylindrical locks:

ANSI and/or BHMA certifications UL listed 5-pin or 6-pin tumblers Concealed mounting screws Options for electrical locking and unlocking

Quality locks have been tested to last a long time. For example, the Schlage D-series and Falcon T-series meet or exceed the 800,000 cycle ANSI Grade 1 requirements. These locks are also constructed of either brass or cold formed steel and treated to withstand corrosion. Heavy duty steel springs in the mechanism add to the durability of the locks.

The different construction specifications meet varying commercial building needs. Standard duty commercial locks are suitable for heavy duty residential use or light to medium duty commercial use, such as interior office doors. Medium duty locks are designed for use in commercial exterior applications that don’t require rigorous security and for interior doors of medical offices, hotels, retail stores, public facilities, churches and apartment buildings. Heavy duty cylindrical locks provide security in exterior and interior applications for industrial facilities, schools, hospitals, offices, retail stores, government/public office buildings and factories.

Cylindrical locks are usually available in both lever or knob designs. Lever locks should meet ADA requirements. Additional options include special finishes to help users identify by touch that the lock leads to a space containing hazardous materials. The best locks include a feature that allows the exterior knob or lever to move freely even when locked; this helps prevent intruders from breaking the lock. When purchasing locks for fire doors, make sure the lock is rated for use on a fire door.

For commercial installations, always purchase commercial cylindrical locks from well-known companies such as Schlage and Falcon. The light duty locks often available from home improvement super centers won’t offer the security or durability required in commercial applications.

The exterior entrances of the building can be secured with a range of deadbolt locks. Security needs will determine whether to use standard or heavy duty lock construction. Standard duty commercial deadbolts work well for office buildings. Heavy duty commercial deadbolts provide the best security. You should look for lock construction that includes a concealed wood frame reinforcer that prevents kick-ins.

You’ll probably want to pair a cylindrical lock with a deadbolt to allow ease of entry. Your choices include lever style locks and knob locks. A heavy duty lever lock is suitable for hospitals, factories and even schools. Buildings with less stringent security needs may opt for standard or medium duty lever locks. Some lever locks are also UL listed for use on 3-hour fire doors. Knobs are the traditional doorknob design. These are also available in medium and heavy duty designs. Knob locks are typically reserved for interior doors of commercial buildings

Interconnected locks are an attractive choice for exterior doors of offices, hotels and light-duty commercial buildings. These locks are called interconnected because the handicapped compliant handles unlatch both the handset and the deadbolt when it’s depressed. The best interconnected locks have a reinforced deadbolt strike to prevent an intruder from kicking the door open.

Interior doors of the building can be secured with a mortise lock. These locks are both attractive and functional. Heavy duty mortise locks are dependable and designed to withstand high-usage and abuse. This makes them ideal for hospitals and schools. When choosing mortise locks, look for designs that include a free-wheeling lever that resists force when locked.

No matter what types of locks are required in a building, most manufacturers will offer a variety of finishes that can be matched across all styles. This allows for a consistent aesthetic appeal throughout the building. Finishes typically include brass, bronze and stainless steel. Expect to pay from $40 for a simple cylindrical lock up to $300 for the finest mortise locks.
