A high security key blank is the uncut key stock for a restricted keyway, a key profile the manufacturer protects by patent so copies cannot be made at a hardware store. We stock, cut and originate these blanks for Medeco, Mul-T-Lock, Schlage Primus and other brands across Maryland, Washington DC and Northern Virginia, backed by our 25 years in business.
A high security key blank is nickel silver key stock, a harder alloy than brass, made for one restricted keyway: the slot profile that manufacturer’s blank fits. Its cuts serve the cylinder: angled cuts that turn a Medeco sidebar, a second locking bar; telescoping pin-in-pin cuts for Mul-T-Lock; side milling for Schlage Primus finger pins.
Three facts decide what we can do with your blank. The keyway family, which cylinder it fits. The patent status: a live utility patent keeps blanks off the open market, an expired one does not. And the cutting method: we code cut from the original key number for every account across the District of Columbia.
The benefit is control. Because the keyway is restricted, nobody can walk your key into a hardware store and get a copy. Every duplicate passes through key control and through us, so the count of keys in circulation is a number you know.
Nickel silver blanks outlast brass under daily use, so keys keep turning for years. Code cutting from the key number cuts every copy to factory depth, not a worn key’s drift. If your building runs open keyways, upgrading is one survey away.
High security key blanks belong wherever a lost key costs money: property offices, medical practices, pharmacies, government contractors and multifamily buildings across Northern Virginia. Any door with a Medeco, Mul-T-Lock, Primus, ASSA or Abloy cylinder depends on them.
They are wrong for a door that never sees a key: a card reader suite, or a passage door left unlocked. A common SC1 or KW1 blank serves a shed or closet. Not sure which keyway you run? We survey it free.
One free survey tells you which cylinders already run a patented keyway, which ones leak copies, and which doors deserve an upgrade. Our locksmith reads every keyway on site and hands you a plain list of what to keep, cut fresh or replace.
Five key systems earned space on our trucks by keeping blanks under control: keyways we can cut, patents still live, and copies you can count.
Medeco M4 blanks carry angled cuts that turn a sidebar, a second locking bar, so we code cut every copy from your original key number.
Mul-T-Lock MT5+ blanks use pin-in-pin cuts, a small pin inside a larger one, which keeps copies off any duplicator and puts every key through us.
Schlage Primus XP blanks add side milling that lifts finger pins, so an existing Schlage master system upgrades cylinder by cylinder without rekeying the building.
ASSA Twin blanks carry two cut rows, standard pin cuts plus a side code, so a large campus keys into one system without exhausting combinations.
A key that must be jiggled: the cuts have worn below factory depth, and every copy drifts further. A key snapped in the plug, the rotating part of the cylinder, from years of flexing. And a key count nobody trusts, because copies leaked after the utility patent expired.
On arrival we read the keyway stamp, gauge the cuts against the code, check the cylinder before blaming the key, then price a fresh blank against rekeying. Locked out? Our mobile units respond 24/7. Call (240) 345-1455 in Maryland or (202) 800-2622 in Washington DC and NOVA.
Worn keys we never duplicate; we code cut a fresh blank from the key number. A snapped key we extract, then cut a replacement from the code. Repair beats replacement while the keyway’s patent is live and the cylinder still turns cleanly; once the patent expires, more blanks only multiply the problem.
We recommend a new key system when the patent has lapsed, blanks are discontinued, or key count is unknown. We match keyway, cylinder format and finish so new cylinders drop into each door with no drilling, then key them into one master system. Measure, match, install, test keys before we leave. Free estimates.
