Ultimate Lock has the ability to withstand up to 4000 pounds of force, to put things in perspective, most deadbolts can only withstand roughly 100-200 pounds of force.
Generally speaking, deadbolts are sturdy locks that can withstand kick in and other forced entry attempts. However, a door with a deadbolt can still be kicked down if the door itself is not solid. So, to protect your door against kick in, you want to make sure both the lock and door are of high-quality grade.
While properly installed deadbolts provide reasonable protection, there are risks. With single cylinder deadbolts, burglars often break door-side windows to simply reach in and turn the latch. Double cylinder deadbolts can slow family members trying to flee from the house in case of fire or other emergency.
Each lock type carries certain advantages; for example, a latchbolt will lock automatically, while most deadbolts require manual locking. On the other hand, deadbolts are widely considered to be stronger and harder to pick than latchbolts.
Locksmiths can install special pins that make it much more difficult, though not impossible, to bump a lock. This is an affordable way to protect your home from lock bumping and lock picking.
The BHMA/ANSI has three, separate grades for deadbolts, simply labeled grades 1 through 3. Grade 1 is the highest quality, and the most dependable deadbolt you can have. Grade 3 is your average deadbolt which will provide an accepted, but minimal, level of security.
Ultimate Lock has the ability to withstand up to 4000 pounds of force, to put things in perspective, most deadbolts can only withstand roughly 100-200 pounds of force.
A minimum of 10, 75-pound strikes are reported to be the equivalent of over 100 foot pounds, which is why the Grade 1 deadbolt locks have been tested. A really strong criminal would have to kick your door over 100 times in order for it to begin to degrade or show signs of weakness.
Well, deadlocks and deadbolts are the same in that they both need a key to lock. However, while a deadlock can only be unlocked in deadlock mode with a key, deadbolts can be locked and unlocked with a key and have a metal lock that extends from the door into the wall.
Start by inserting the closed "looped" side of one bobby pin into the bottom portion of the lock. Use the second bobby pin, broken in half, toward the top of the lock and move it back and forth. This motion should set the pins and cause the deadbolt to unlock.
1. Replace the trim around your door frame. A thick trim that covers the strike plate (the metal part that's on the door frame) will prevent someone from slipping a credit card between the bolt and the plate. A door that swings inward will not be affected by a thicker or overlapping trim.
A magnet cannot entirely unlock a deadbolt.
Hinges are located on the side of the door that swings forward, so if you see hinges, you should avoid kicking down the door. Exterior doors for residential buildings, such as homes or apartment buildings, generally swing inward. Many commercial buildings, however, usually have exterior doors that open outward.
Insert the two points of the bobby pin into the lock. Press the bobby pin forward into the lock— depending on the door, simple forward pressure can be enough to open the lock. Picker of Locks says to keep even pressure on the pin as you elevate each lock. Using a second pin that is straightened may help.
Interior doors should require no more than 5 lbs. of force to open. This does not apply to the initial force needed to overcome the weight of a motionless door. Open the door gradually; do not “jerk” it open.
Most interior doors have hollow wood or fiberboard materials, and so doesn't pose a big challenge. These doors do not offer much in terms of security. But outside doors have a solid core made with shaved wood and laminate, so it's hard to kick down.
For most commercial and industrial high security applications with Herculite glass doors or hollow metal frames with wood or hollow metal doors, an electro- magnetic door lock with at least 1500 lbs. of holding force is recommended. When attacked with extreme force, these doors may not release, but may sustain damage.
Though it take 1200lbs to force the lock open, under rated operating conditions, someone could apply more than that by using some sort of lever. It is also possible that the locks are not being used under rated conditions.
This is one of the most secure solutions out there to burglar-proof your front door from the inside. A steel horizontal security bar is extremely durable and withstands really high forces, so it definitely protects your door from kick-ins.
ABUS Granit™: one of the world's most secure padlocks with a tensile resistance of over six tonnes. Granit locks have a tensile resistance of over six tonnes, making it almost impossible for attackers to release the shackle from the lock body by force.
Generally, single-cylinder deadbolts are less secure than double-cylinder options. They could potentially allow easier access to the home from intruders in the know. Furthermore, they're easy for small children to use, which means they could get outside without anyone being aware.
Also in the non-forced entry category, there is no doubt Schlage is better. With a better, more precise manufacturing process and 2 additional security pins than the Kwikset deadbolt, Schlage locks are significantly harder to pick, bump or compromise in non-destructive ways.
What is Lock Grade 3? Grade 3 Deadbolts are the Least Secure and NOT Recommended. Lock grade 3 is the least secure of the three lock grades. It should be considered basic door hardware, for non high security situations, and is the least expensive. It is also the common lock you will find on homes.
