What's the difference between high-security and regular deadbolts?

A standard deadbolt from Home Depot can be picked by a hobbyist in 30 seconds and bumped open even more easily. High-security locks have specialized pin designs that defeat these attacks, hardened steel that resists drilling, and restricted keyways that prevent unauthorized key copies. They're also built to commercial specs—much heavier duty.

How much more do high-security locks cost?

High-security hardware represents a higher investment than standard hardware. High-security deadbolts provide significantly better protection. For commercial applications or full-building installations, we provide transparent diagnostic quotes.

Can I get extra keys later?

Yes, but only through authorized channels. You'll receive a key control card with your installation. Additional keys requires presenting this card at an authorized dealer. We can cut additional keys for you by validating your authorization. This is the whole point—YOU control who gets copies.

Which brand is recommended?

Medeco is the most recognized name in the US with excellent domestic support. Mul-T-Lock offers exceptional pick resistance and is popular for commercial applications. Abloy (Finnish) uses a unique rotating disc design that's virtually pick-proof. We can explain tradeoffs for your specific situation.

Is it worth upgrading my home to high-security locks?

For most residential situations, quality Grade 2 deadbolts plus smart practices (lights, cameras, solid doors) are sufficient. High-security makes sense if you store significant valuables, have specific threats, or simply want maximum peace of mind. We won't oversell—but we'll explain your options honestly.
