Can my high-security keys really not be copied?

Right. Brands like Medeco and Mul-T-Lock use patented, restricted keyways, so blanks aren't sold to copy shops. Keys are only cut by an authorized locksmith for people on your registered key-control list.

Do I have to replace my whole door to upgrade?

Usually not. Most high-security cylinders and deadbolts fit standard commercial door prep, so we swap the lock and keep your existing door in most cases. We confirm fit during the free on-site assessment.

Can you put all my doors on one key?

Yes. We can set up a master key system so one key opens designated doors while staff keys open only what they should. We map this out before install and keep a serial record of every key.

How fast can you install high-security locks?

We're mobile and typically reach North Dallas locations in about 20-30 minutes. Most single-door installs are done same-visit; larger master key systems are scheduled after the assessment.

How High-Security Locks Installation Works

Three steps from your call to keys in hand, all done at your location.

1
On-site assessment
A tech walks your doors, checks the frames and existing hardware, and tells you which entries actually need a high-security upgrade. No upsell on doors that don't need it.
2
Flat quote and lock selection
We recommend the right grade and brand for each door, set up your restricted key plan, and hand you a flat price before any work starts.
3
Install and key handoff
We fit the cylinders, test every lock and key, and register your restricted keys so only people you name can ever get copies cut.

Frequently Asked Questions

High-security locks add drill-resistant hardened steel, pick- and bump-resistant pin design, and a patented keyway. The patent means no hardware store or kiosk can legally cut a copy of your key.
