High-security keyed and electronic door locks stand up to even the most advanced attempts at defeating your security. They’re an essential part of protecting your business, and meeting your responsibility to protect the information of others in your custody. High-security door locks also stand up to abuse and are an excellent solution when your business is an attractive target like a jewelry or electronics store or a commercial storage facility.

Enhanced Residential High-Security Locks

High-security locks aren’t just for commercial properties. Installing high-security deadbolts on your home’s exterior doors provide tamper-proof protection while you’re at work, on vacation, and especially while you’re at home. What makes high-security deadbolts special is the internal lock mechanism and the specialized dimple keys that have a rectangular blade with multiple cone-shaped dimples at various depths. These dimple keys come with a card or code that enables the owner to get duplicates made but prevents anyone else from making copies.

We also offer high-security electronic door locks and smart locks for convenience. If you have a home office or other interior space that requires extra security, especially if sensitive information or other vulnerable items are stored there, we can also install high-security locks on your interior doors.

Types of High-Security Locks and How They’re Used

Mechanisms in high-security locks include cam locks that can be custom fit to secure cabinet doors, lockers, and even high-end auto accessories like racks. Rim cylinders are often used on apartment doors and as part of panic exit devices. Mortise cylinders are similar to rim types, used for certain cam-based applications. High-security versions include protective steel components for protection against drilling.
