The SIMLock is Affordable & Effective.
We invented our affordable and easy-to-install device so that you could be safer...one small step towards our fight against violence, forcible entry, burglary and domestic abuse.


Prevent home invasions, forcible entries, "lock bumping" and in-home burglaries with the SIMLock


Your home should be your sanctuary, offering protection within its walls...but according to statistics:


- One woman is assaulted every two minutes

- 4 out of 10 assaults take place in the victim's home

- More than 14 percent of burglaries occur when the victims are in the house

- 60% of home burglaries involved forcible entry, this includes use of unauthorized keys

- 64% of American homeowners have knowlingly circulated their house keys outside their immediate family.


How can we bring these statistics down and make our homes safe? SIMLock is one step that can help.

The SIMLock™ allows the user to engage a secondary lock with the ease of flipping a switch, keeping unwanted intruders out. Installed on the deadbolt, SIMLock prevents forcible entry – whether through an unauthorized key duplicate, lock picking or the dangerous “lock bumping” trend.

The SIMLock offers added peace of mind and a greater sense of security in the one place that you need it most – your home.

The SIMLock is a home safety device that can be easily installed on any regular deadbolt.*

The SIMLock, made from zinc, is manufactured entirely in the United States. When engaged, the lock sits against the deadbolt lever preventing it from moving to the ‘unlocked’ position. When the SIMLock is engaged, the deadbolt cannot be picked by a locksmith, house key, unauthorized key duplicate or bump key.
