Expertise- Top Locksmith In St. Louis MO

Master Locksmith was voted “Best Locksmith In St. Louis” by a third-party review site- Expertise.

What makes a High Security Lock?

Although high-security locks aren’t impenetrable, they withstand manipulation and forced entry attempts much better than traditional locks. The label of “high security” means that the lock is able to resist an unauthorized entry attempt for a certain amount of time (standardized by testing bodies like ANSI and UL).

What is the highest security lock?

The most common high-security rating is UL437, which covers locks and cylinders. This category is tested for unauthorized opening from bypass, lock-picking, impressioning, and destructive entry. Most major North American manufacturers supply UL437 listed locks and have patented and controlled key distribution available.
