What Makes a Lock "High Security"?

Pick Resistance — Advanced pin configurations that defeat standard lock picking techniques.

Drill Resistance — Hardened steel inserts and anti-drill pins that resist power drill attacks.

Bump Resistance — Special pin designs that prevent bump key attacks.

Key Control — Restricted keyways mean keys cannot be duplicated at hardware stores. Only authorized locksmiths (like us) can make copies.

UL Listed — Tested and certified by Underwriters Laboratories for their security rating.

Mul-T-Lock

Mul-T-Lock is an Israeli-designed lock system known for its patented telescopic pin tumbler mechanism. Each key pin contains a smaller pin inside it, making picking virtually impossible. We install Mul-T-Lock deadbolts, knob locks, padlocks, and cylinders for both residential and commercial applications.

Medeco Locks

Medeco, made in the USA, uses a patented rotating pin tumbler design that requires keys to be cut at precise angles. Medeco locks have been the security standard for government buildings, banks, and high-security facilities for decades. We carry the full Medeco residential and commercial line.

Who Needs High Security Locks?

High-security locks are especially recommended for: luxury condos in Aventura and Bal Harbour, commercial businesses, medical and legal offices with sensitive information, homes in high-value neighborhoods, rental properties where key control is essential, and anyone who wants the highest level of physical security available.
