Lock Rekey in Orange County

Rekeying keeps your existing locks and makes every old key useless. Each lock takes about 10 to 15 minutes, a whole house is usually done within an hour, and the cost is a fraction of replacing the same locks. It's the standard move after buying a home, losing keys, or a roommate change.

What rekeying actually does

Inside every standard lock cylinder is a row of pins that match one specific key. Rekeying swaps those pins for a new combination, so the lock accepts a brand-new key and rejects every old one. Same lock, same door, new keys. Nothing about the lock's look or strength changes; what changes is who can open it.

A rekey visit is also the natural moment to have all your locks keyed alike: one key that opens the front door, back door, and garage side door. If your locks share the same brand or keyway, this usually adds little or nothing beyond the per-cylinder work.

Rekey or replace? A simple rule

Rekey when the hardware is fine and the problem is who has keys: you just bought or moved into a home, keys were lost or stolen, a roommate or tenant moved out, a contractor's job wrapped up, or an employee left the business. You're paying a fraction of replacement cost to reset access.

Replace when the hardware itself is the problem: the lock is worn, sticking, corroded (common near the coast in Newport Beach, Laguna Beach, and Dana Point), visibly dated, or you want an upgrade like a deadbolt, high-security cylinder, or keypad lock. If a lock is failing mechanically, rekeying it just gives new keys to a dying lock.

Just bought a home? Rekey first, unpack second

A resale home's keys have usually passed through previous owners, their family and friends, real-estate agents, stagers, inspectors, and contractors. There is no way to know how many copies exist, and door codes for garage keypads travel the same way. Rekeying every exterior lock on move-in day is the single highest-value security purchase for a new homeowner, and it's cheap compared to almost anything else on the moving bill.

The same logic applies to landlords between tenants and to businesses after staff changes. California landlords commonly rekey at every turnover, and many property managers make it standard procedure.

How rekeying is priced

Expect two components: a service call fee for the visit and a per-cylinder charge for each lock rekeyed. Deadbolt-plus-knob combos on one door count as two cylinders unless they're keyed together. High-security cylinders and mailbox or cabinet locks price differently; ask when booking.

For businesses and landlords with many doors, a master key system is often smarter than a plain rekey: individual keys open individual doors while one master opens everything. It's set up during the same kind of visit.

Lock Rekey: frequently asked questions

How much does it cost to rekey a lock?

Rekeying is priced per lock cylinder plus a service call fee for the visit, and a typical single-family home with four or five exterior locks still totals far less than replacing the same hardware. High-security cylinders price differently than standard ones, and you'll have exact numbers before work starts.

Is rekeying cheaper than changing the locks?

Yes, significantly. Rekeying reuses your existing hardware and only changes the internal pins, so you pay for labor and new keys. Full replacement adds the cost of new hardware for every door, which climbs fast for quality deadbolts or smart locks.

Can all my locks be rekeyed to use one key?

Usually. If your locks are the same brand or share the same keyway, they can be keyed alike so one key opens everything. Mixed brands can sometimes be matched by swapping cylinders; a locksmith can tell you door by door what's possible.

How long does it take to rekey a whole house?

About 10 to 15 minutes per lock once the locksmith is at the door, so a typical home is done within an hour. The work happens with the locks in place or with cylinders briefly removed, with no damage to doors.

Should I rekey after buying a house?

Yes. It's the standard recommendation for every home purchase. Previous owners, agents, inspectors, and contractors may all hold working copies of your keys, and rekeying on move-in day makes every one of them useless at once.

Can smart locks or keypad locks be rekeyed?

The mechanical key cylinder that most smart and keypad locks include can be rekeyed like any other lock. Codes are separate; change those yourself in the lock's settings or app, and delete any codes you didn't create.

I'm a tenant. Can I rekey my apartment?

Most California leases require the landlord's consent to rekey or alter locks, and the landlord typically keeps a copy of the new key for emergencies. Ask first; landlords usually agree, especially after a lost key or a safety concern.

Does rekeying make my lock more secure?

Rekeying resets who has access, which is usually the real risk, but it doesn't change the lock's physical strength. If you want more resistance to picking, bumping, or forced entry, that's a hardware upgrade: a Grade 1 deadbolt or high-security cylinder, installed during the same visit.
