Medeco, Mul-T-Lock, and ASSA ABLOY cylinders built to resist picking, drilling, and bumping, with restricted keyways: no kiosk copies, no copies at all without your signed authorization.
Newport Beach Locksmith
Standard locks share an open secret: their keys can be copied anywhere, by anyone holding them for thirty seconds, no questions asked. For a Newport Beach CA home with staff, renters, contractors, and guests cycling through, that secret is the whole security problem. High-security locks exist to close it, with keys that cannot be duplicated without your authorization and cylinders built to shrug off the attacks standard hardware folds to.
Newport Beach Locksmith (CA License LCO4446, team behind Golden Locks) installs and services high-security cylinders from Medeco, Mul-T-Lock, and ASSA ABLOY across Newport Beach CA, Newport Coast CA, Corona del Mar CA, and Laguna Beach CA. These are the locks on the homes behind the gates up the Coast, on harbor-front properties, and on any door where the owner wants to know, not hope, who holds working keys.
The heart of the system is the restricted keyway. Your keys carry a patented profile that blanks do not exist for in the open market. Copies are cut only by authorized dealers, only against your signature card, and every copy is recorded. Hand a key to a housekeeper and you hold the only path to its twin.
Services
Four protections standard cylinders simply do not offer, in plain words:
Honest pricing
| Service | Typical price range |
|---|---|
| Service call (Newport Beach CA) | $19 to $35 |
| High-security cylinder fitted (per lock, Medeco class) | $195 to $320 |
| High-security deadbolt complete (per door) | $260 to $420 |
| Restricted keys, authorized copies | $18 to $35 each |
| Rekey high-security cylinder (per lock) | $45 to $75 |
| Whole-home high-security package | Quoted on site |
| Key control setup + records | Included with install |
| Smart + high-security hybrid doors | Quoted on site |
High-security quotes name the brand, the keyway, and the per-lock price before fitting. You will also see the standard-lock price beside it, so the upgrade decision is yours with clear eyes.
How it works
Call (657) 680-4999. Staff, renters, and second-home patterns shape the plan.
Medeco, Mul-T-Lock, ASSA ABLOY compared in hand, with key control explained plainly.
Cylinders set, strikes reinforced, doors aligned, finishes matched.
Numbered keys, your authorization card, and a copy record that starts clean.
Local & proud
The natural home for restricted keyways is Newport Coast CA, where estate staff, services, and guests rotate weekly and owners are often away for stretches. A key handed out there should be a key that cannot quietly become three keys. We retrofit high-security cylinders into the existing premium hardware those homes already wear, so the street side looks untouched while the security underneath changes completely.
Harbor-front and Peninsula homes come for the second reason: attack resistance. Waterfront doors are visible, valuable, and often empty on weekdays. Pick, bump, and drill resistance, married to a reinforced strike, is the honest answer, and we fit it without turning your entry into a vault door's looks.
Good to know
Here is a test worth doing mentally: hand your house key to anyone, a valet, a contractor, a date, and count what they could do with thirty seconds at a self-serve key kiosk. With a standard key, the answer is own a copy. No record, no trace, no limit.
Restricted keyways flip that answer to nothing at all. The blank does not exist outside authorized channels, the machine will not cut it, and your signature card is the gate. For homes where keys must circulate, key control is not a luxury feature. It is the feature.

Good questions
A high-security cylinder fitted runs $195 to $320 per lock, complete high-security deadbolts $260 to $420 per door, and authorized key copies $18 to $35. Whole-home packages are quoted on site, per door, before any fitting.
It means your key's blank is patented and controlled. Copies can only be cut by an authorized dealer with your signature card on file. A hardware store kiosk cannot copy it, legally or physically.
Both are excellent. Medeco is the American standard with superb key control, Mul-T-Lock brings telescopic pin technology and great retrofit range, and ASSA ABLOY owns much of this world. We compare them in hand at your door and fit your doors and budget.
Usually, yes. The cylinders retrofit most quality locksets and deadbolts, keeping your handles, finishes, and street-side look. We confirm compatibility at the door before quoting.
Because every key is logged, we know how many exist. Rekeying the cylinder retires the lost key completely, and new keys are cut against your card. Lost keys stop being a lingering worry.
For long-term and high-value rentals, key control alone often justifies it: tenant keys cannot be copied during the lease. For short stays, smart locks usually win. We will compare both for your property honestly.
