A spare key should glide, not jiggle. Our Mission Viejo techs cut precision duplicates from clean data, test them in your lock, and handle restricted high-security keys the legal way.
Mission Viejo Locksmith
Everyone has lived the hardware-store key: cut in forty seconds, dead in the lock. The problem is rarely the machine. It is the copy-of-a-copy problem: each generation drifts a little further from the original cuts until the key is a rumor of the real thing. Precision duplication starts from clean data and ends with a key tested in your actual lock.
Mission Viejo Locksmith (CA License LCO4446, team behind Golden Locks) cuts keys across the valley daily: house spares for new homeowners, extra sets for growing drivers, landlord sets counted and documented, and restricted keys duplicated with proper authorization.
Because we are mobile, the cutting machine comes to you. Keys are cut at your door, tested in your locks, and adjusted on the spot if a worn lock needs a sympathetic cut. No second trip to a counter, no bag of almost-right blanks.

How it works
Call (657) 680-4448. Stamps on the key head, like 'Do Not Duplicate' or a brand name, tell us a lot.
Plain words, per key, before the machine spins.
Original or decoded cuts, not a tracing of wear.
Every key runs in its lock with you watching. Jiggle-free or we adjust it.
Local & proud
Duplication calls in Mission Viejo spike with life events: escrow closings in Madrid and Barcelona, a teenager's first house key in Canyon Crest, college kids home for summer in Aegean Hills needing the set they lost in spring. Landlords along the Los Alisos corridor book counted sets with every turnover.
Because the machine rides in the van, spares usually happen as an add-on during rekeys and lock changes, at the friendliest price of the day. One trip, whole household covered, and the under-the-mat era officially over.
Good to know
Honestly? On a standard key, those words are a request, not a law, and any shop can copy it. The real protection lives in restricted keyways: patented blanks that only authorized dealers can buy, with duplication tied to your signature card or account.
If losing control of copies worries you, ask us about moving one important door to a restricted cylinder during your next rekey or lock change. That is the version of 'do not duplicate' with teeth, and we handle the paperwork properly.

Good questions
For standard keys, yes, the stamp alone is not a legal bar. For restricted and patented keyways, we duplicate only with proof of authorization, and we keep records. We will tell you which kind you hold in seconds.
Usually copy drift: your original was already a worn copy, and the new one copied the wear. We cut from the original cut depths instead, and test the result in your lock.
Yes. We decode the lock itself and cut a key from its data. That is also how broken keys get replaced from the pieces.
Our usual advice: one per adult and older teen, one with a trusted neighbor or in a lockbox, and one spare set indoors. We cut the whole plan in one visit.
Daily. Counted, labeled sets with a written record, usually paired with the turnover rekey so the new tenant's set is the only set that exists.
Yes, with authorization on file. Protected keyways are controlled for good reason, and we follow the system exactly, which is what makes your keys safe from casual copies.
