What Makes a High-Security Lock?
Locks considered high-security are evaluated based on standards established by Underwriters Laboratories (UL) and Building Hardware Manufacturers Association (BHMA). Generally, a Grade 1 security mortise lock, auxiliary deadbolt, padlock, or multipoint lock will have a high-security cylinder installed.
UL437 is the most common high-security rating for locks and cylinders. Manufacturers in North America offer locks that meet the UL437 standard and have the patented and controlled required distribution. These locks are tested to ensure they cannot be opened through bypass, lock-picking, or destructive entry.
Where Should High-Security Locks Be Utilized?
These locks are recommended for use in businesses, especially at entrances. It is also advisable for business owners to install them on doors leading to places where valuables such as money, safes, computer rooms, or file rooms are kept.
These locks can also be installed in residential homes, not just businesses. You can place them on your front door or garage to stop people from entering your home without permission. Some homeowners even install them on their home office doors to increase security for valuable items and documents.
