One manager key that opens everything, staff keys that open only their doors. We design, install, and document master key systems and commercial rekeys for Mission Viejo businesses, with key control in writing.

Mission Viejo Locksmith
Business key problems are quiet until they are expensive: the departed manager whose key was never collected, the cleaning crew with a copy too many, the new tenant who inherited a lock story nobody can reconstruct. A commercial rekey with a real master key system ends the guessing. Every door gets a place in a written plan, and every key gets a name next to it.
Mission Viejo Locksmith (licensed team behind Golden Locks, CA License LCO4446) builds and services master key systems for shops at The Shops at Mission Viejo and the Kaleidoscope, offices along Los Alisos Blvd and Marguerite Pkwy, medical and dental suites near Mission Hospital, restaurants, and property portfolios across the valley.
We survey your doors, design the hierarchy with you, rekey or replace cylinders to restricted keyways when control matters, and hand over a key control record you can actually run a business on. Panic bars and access control hardware are serviced as part of the same visit conversation, quoted plainly alongside the key work.
Services
This is the difference between a ring of mysteries and a system you can hand to a new manager with confidence.

How it works
Call (657) 680-4448. Door count, current hardware, and what is worrying you gets the survey booked.
We map doors, levels, and key holders with you, then quote the whole project.
Cylinders set to the hierarchy, hardware serviced, exit devices checked.
Keys issued against signatures, control documents handed over, and a simple process for future changes.

Local & proud
Mission Viejo commerce has its own shape: retail tenants inside The Shops and the Kaleidoscope with mall rules about hours and hardware, professional suites along Marguerite Pkwy, medical offices near Mission Hospital where access levels carry compliance weight, and property managers juggling units from RSM to Ladera Ranch.
We work inside those realities: after-hours installs so your doors open on time, coordination with property management, and systems designed so a single staffing change never forces a building-wide rekey again. HOA and community facilities, clubhouses, pool gates, and maintenance rooms across the villages, are regular stops on the same route.

Good to know
Ask three questions of your current setup. How many keys exist for your main door? Who holds them? Could you prove it? If the answers wobble, your lock is a formality, no matter how good the hardware is.
Our surveys start with that audit, kindly and without scare tactics. Often the fix is a modest rekey to a restricted keyway plus real records, not a building full of new locks. Control, not hardware, is usually the missing piece.

Why choose us
Mission Viejo Locksmith is run by the licensed crew behind Golden Locks Inc., CA Locksmith License LCO4446. What makes us different is local fluency: our techs check in at the Coto de Caza guard gates and the Covenant Hills gate weekly, carry the paperwork guards ask for, and know which villages want a resident call before a vendor van rolls through.
That fluency saves you two headaches: a tech turned away at the gate, and an HOA letter about a finish that breaks community rules. Add up-front pricing, one-visit fixes, and a real warranty on parts and labor, and the choice makes itself.

Good questions
Rekeying changes which key works. A master key system adds structure: levels of keys, from a single door up to a grand master, all planned and documented. Most businesses need both together, which is how we install them.
Yes, that is the point of the hierarchy. A key is cut and pinned to open only its level: one office, one department, or the whole site for management.
Restricted keyways. The blanks are controlled and only available through authorized channels with your approval on file. Copies stop being a thing anyone can do on a lunch break.
With the audit and survey. We map what exists, then rekey the site into a documented system. Most valley businesses are fully under control within one or two visits.
Yes, as part of the same relationship. Exit hardware is inspected and serviced during system work, and electronic access options are assessed honestly for the doors where they earn their cost.
Yes. Retail and medical schedules are respected, and most install work can happen early, late, or between rushes so your doors and your day both stay on track.
