Since Classic Primus can be keyed in to existing Classic key systems, Classic Primus is still commonly used for key system upgrades. Everest Primus is protected by a total of four utility patents vs. two for Classic Primus. These patents allow Schlage to control the distribution of keys and provide a dealer or end user with geographic exclusivity on Primus keys.

Another difference between Everest Primus and Classic Primus is that Everest Primus uses a larger key bow that provides you with additional space to stamp information and makes the keys easier to handle.

SCORPION

Scorpion offers a simple, cost-effective answer to the key control problem. The Scorpion CX-5 line of products utilizes a security ridge milled into the side of the key blank at the factory. In addition to the standard cuts on the top of the key blade, this ridge provides an additional 200 extra keyways to provide pick resistance and duplication control. Keys can be code cut or duplicated on any standard key machine.

The shear line and sidebar anti-drill pins provide drill resistance while the combination of industrial-strength brass nickel and steel components offers a high degree of wear in the commercial application. Signature cards, kept on file by the locksmith, control authorized key duplication.

The combination mortise/rim cylinder comes with tailpieces, cams and screws to use it in either application. Deadbolts are available in all three grades and knob/lever cylinders come with multiple tailpieces to fit most common Grade 1 and Grade 2 hardware.

YALE

The patent protected Yale Security Cylinders make use of two independent locking mechanisms to provide high security protection, with a six- or seven-pin tumbler mechanism with spool drivers, and a five tumbler rotating disc/sidebar. The six or seven pint tumblers block the top of the keyway, while the five spring loaded, rotating discs block the bottom of the keyway. The operating key has a side bitting as well as the bitting to accommodate the pin tumblers. Once pin tumblers and the rotating discs align clearing the shearline, the cylinder plug can be rotated.

The Yale Security Cylinders use the “GST” and “VYZ” families of surety keyways in these cylinders. In addition to the key restrictions, the security cylinders are available for those applications that require UL 437 pick and drill resistance. These lock cylinders have a hardened stainless steel cylinder head and rotating plug face to the mechanical security

The Yale Security Cylinders are available in three Security Levels. The base level, level 1 is the Registered Distributor. This level uses the GST family of keys that come from the factory cut for the rotating disc tumblers. The pin tumbler bitting is cut by the locksmith enabling rekeying of the lock cylinders. Additional keys are available. Level 2 is the Registered to End User. This level uses the “GST” family of surety keyways. Lock cylinders are only available from Yale. The cylinders are factory assembled and keys are available from Yale. To obtain keys, an authorized signature is required from the building owner. Level 3 Registered to End User (Restricted Keyways) is the highest level of security. Level three lock cylinders use the “VYZ” family of restricted keyways. These cylinders are sold by locksmith wholesalers for specific jobs. Cylinders are factory assembled and keys are factory cut. Additional cut keys are only available from Yale and require an authorized signature from the building owner.

SELL THE PROPER LEVEL OF SECURITY

Key control is an essential part of the overall security package you provide to your customer. The needs of residential, light commercial, and heavy duty commercial customers vary by application, situation and budget.

Key control on exterior doors may only solve some of your customer’s needs. Dual or crossover types of key control exist that allow one key to fit all locks. The high security or restricted key will pass standard and high security locks, allowing it to act as a master key or sub-master. The standard keys will still work the low security interior locks.

What does the customer need? Who needs to go where? Not all employees need a front door key. By consulting with the customer and asking the questions who, how, and where, you’ll uncover their specific needs. Then, you the locksmith professional will have the necessary customer input to determine the proper level of security for your customer.
