Lock Bumping Prevention

Lock Bumping As an industry leader in locksets, Kwikset wants to proactively inform our customers of this industry issue.


What Is lock bumping?

For many years, Locksmith Professionals have utilized several methods and tools to bypass pin and tumbler locks for legal purposes. One such technique is called “bumping.” Lock bumping, also referred to as key bumping is an attack technique using specially cut keys, known as bump keys, that can defeat conventional pin and tumbler door locks.

Does Kwikset Offer any products that specifically guard against lock bumping?

Kwikset offers the high-security ANSI Grade 1 980 Deadbolt which features SmartKey™ technology and BumpGuard™. The patented design of SmartKey provides enhanced protection against lock bumping! The BumpGuard component of a SmartKey lock incorporates a patented side locking bar which replaces the traditional pin and tumbler design, to provide protection against lock-bumping techniques.

Another innovative feature of SmartKey technology is that it gives you the ability to re-key your lock in less than 30 seconds while still providing superior key bumping security. Now, with SmartKey technology, if you are concerned about a lost or unauthorized duplication of your key, you can simply replace the key and not the door lock.

How Is lock bumping Done?

Lock Bumping uses the basic principles of physics by inserting a specially cut “bump-key” (also referred to as a 999 key) into the lock, then by using any type of object the key is then struck or “bumped”. The energy transferred from the impact forces the pins within the lock up above the shear line for a fraction of a second enabling the lock to be opened. For more information on lock bumping please view the video above.

How Common is lock bumping?

According to statistics provided by the National Crime Prevention Council (NCPC) and the Department of Justice, nearly 2/3 of all break-ins occur with no sign of forced entry. Since there is no way to determine the actual method, it would be impossible to know for sure how many break-ins were a result of lock bumping. However, there are steps you can follow to help protect yourself, family and property. Door locks are just one form of security for your home. Consumers can also protect their homes by lighting the entry and perimeter areas, using alarm systems, motion detectors and even the family pet as deterrents to those that would attempt to enter your home.

What is being done to prevent lock bumping?

State and federal laws prohibit the distribution of “locksmithing devices” to anyone other than lock manufacturers or others with a recognized legal purpose. Kwikset is working closely with the industry trade association, Builders Hardware Manufacturers Association (“BHMA”), to minimize the risk that such devices can be obtained by individuals for improper purposes. In addition Kwikset offers SmartKey technology and the patented bump-guard feature all designed with high-security in mind.
