Frequently Asked Questions

How much do high-security locks cost?

High-security locks range from $150-$500 per lock including installation. Medeco and Mul-T-Lock are the most popular options. Call (210) 348-3677.

What makes a lock high-security?

High-security locks feature anti-pick pins, hardened steel, anti-drill plates, and patented keyways that prevent unauthorized key duplication.

Can high-security locks be picked?

While no lock is 100% pick-proof, high-security locks like Medeco and Abloy have never been reliably picked in real-world conditions. They far exceed standard lock security.

What is key control?

Key control means keys can only be duplicated with proper authorization. Unlike standard keys that anyone can copy at a hardware store, high-security keys require an ID card to duplicate.

Are high-security locks worth the cost?

Yes, especially if you have valuables, a home office, or want maximum peace of mind. The cost is a small fraction of what a burglary would cost.
