High-Security Locks. Restricted Keyways. Audit-Ready Key Control.

ANSI Grade 1 measures forced-entry resistance: 10 strikes at 75 lbs. High-security adds three things Grade 1 does not require: pick resistance rated for 10 minutes minimum under skilled attack, drill resistance via hardened steel inserts, and restricted keyways that prevent unauthorized key duplication. Medeco, Mul-T-Lock, Schlage Primus, and Abloy all meet UL 437 or equivalent, which is the combined standard.

A restricted keyway is a patented key profile that hardware stores do not stock. Keys can only be cut by an authorized dealer after you present an authorization card and verify ownership. When an employee leaves, you collect the key instead of rekeying every lock in the building. For a 20-door office, that key control saves hundreds of dollars per turnover event.

Many commercial property and business owner policies offer a 10 to 20 percent premium reduction for UL 437-rated locks on server rooms, pharmacies, jewelry display areas, and storage vaults. Some policies require them for coverage of specific assets. Ask your carrier for the exact language. We provide a written statement of the installed lock model and UL rating for your records.

Medeco uses rotating pins: each pin must both lift to the right height and rotate to the correct angle before the lock opens. Mul-T-Lock uses telescoping pins where inner and outer pins must align independently, plus an Interactive element in the key that engages a sidebar in the cylinder. Both resist picking and bumping through different mechanisms. Medeco has a broader dealer network in the Austin area; Mul-T-Lock is more common in government and institutional work. We stock both.

Yes. We design the new high-security cylinders into your current key hierarchy so your existing master keys continue to work. The restricted keyway patent applies only to the individual keys cut under it, not to the overall master-key tree. We map your current system before ordering cylinders so there are no surprises on install day.

Schlage Primus cylinders run $150 to $300 each plus $75 to $125 labor per door. Medeco runs $200 to $400 per cylinder plus $100 to $150 labor. Mul-T-Lock is $250 to $500 per cylinder plus $100 to $150 labor. Abloy Protec runs $200 to $500 per cylinder plus $100 to $150 labor. A 10-door office prioritizing three entry points and one server room typically runs $2,500 to $4,500 total. Exact quote provided before any work begins.
