Residential lock grades and what they mean

The importance of having the correct type of locks installed in your home cannot be overly stated. Today’s locks come in many shapes, sizes and security levels designed to fit any type of application . There are auxiliary locks, digital lock sets, various types of knobs, levers and deadbolt locks, just to name a few. Each of these lock types is available in various security levels (professionally referred to as grades) which are designed to meet various customer needs. Grade 3 is the lowest security level where the lock cylinders and lock itself is usually made out of plastic or a plastic like material.


These low security locks offer minimal protection because they can easily be picked, hammered off, broken or jammed. Grade 2 locks are considered medium level security grade, as these locks usually offer pick resistance attributes from forced entry tools such as spool pins, drivers and serrated keys.


Grade 1 locks are the most secured level locks and are made of better quality materials than Grade 3 or Grade 2 locks. They are fireproof and physical attack resistant and therefore are usually the most common type of locks purchased for homes because they provide higher level security and last much longer than grade 2 or 3 locks.


Grade 1 locks will often have built in features to resist manipulation and physical alteration. The locking cylinders on high security Grade 1 or 2 locks have a  non paracentric keyway and stainless steel pins and wafers making them a much safer choice for customers looking for the best possible security for their doors.


When choosing a lock for your home you should always consider the grade level of any specific lock to ensure it meets your need. While Grade 1 locks are more secured and sturdy, it is sometimes referred to use lesser secured locks for certain applications in a home or office space. For example, locks installed on home bathroom doors are usually of a lesser security level as they are not required to be fireproof or pick resistant.


The most basic type of residential lock is a door knob or lever handle lock. These locks feature keyholes in the middle of the handle that when turned, lock the door. These type of locks offer a lower level of security as they use a small spring piece or a plastic type of material inside them. They are fairly easy to pick and bypass and therefore will usually be found in bathrooms or linen closets in homes and apartment settings.


Another popular type of locks are deadbolt locks, which feature solid steel bolts that slide into the door frame by several inches. They are not spring-loaded and must be manually moved into position in order for them to work. Since the bolt extends several inches into the door frame and is made of solid steel, it is tremendously strong and can withstand a great deal of force. Deadbolt locks can be found in most New York City apartments and are a fantastic option that is reliable and affordable for most homeowners and tenants alike.
