Lock Rekeying
If you've just handed over a key to a contractor, ended a lease, or moved into a home on Anza Avenue where previous tenants may still have copies floating around, you don't necessarily need brand-new hardware — you need lock rekeying. Rekeying reconfigures the internal pin stack of your existing lock cylinder so that every old key becomes permanently useless, while a fresh key cut to the new configuration is the only one that works. It's a precise, mechanical process that our trained, insured technicians perform on-site, right at your door anywhere in Torrance.

“A1 Torrance Locksmiths operates as a fully mobile, 24/7 service — we come to you, whether you're in Old Torrance, Seaside Ranchos, or just off Hawthorne Boulevard. Because we don't operate from a fixed shop with overhead costs, we can dispatch quickly and confirm an exact, up-front price before a single tool leaves our bag. Rekeying is almost always less costly than full lock replacement because the labor involves only the cylinder internals — the hardware you already own stays exactly where it is.

How Lock Rekeying Actually Works — and Why It Beats Full Replacement
Every pin-tumbler lock — whether it's a Kwikset entry knob, a Schlage deadbolt, or a heavy-duty mortise lock on a commercial door — contains a series of driver pins and key pins inside the cylinder. When the correct key is inserted, those pins align perfectly at the shear line, allowing the cylinder to rotate. Rekeying means our technician removes the cylinder, replaces the key pins with a new set sized to a different key cut, and reassembles everything. The lock body, the strike plate, the door hardware — none of it is touched. You keep the same deadbolt or mortise lock you already trust, and the old keys simply cease to function.
For Torrance homeowners and business owners alike, this matters because full replacement involves purchasing new hardware, disposing of functioning equipment, and often paying for additional installation labor if the door prep doesn't match the new lock's dimensions. Rekeying sidesteps all of that. Our technicians carry a full kit of replacement pins and follower tools for the most common residential and commercial lock brands, so the job is typically completed in a single visit — no return trips, no ordering parts online, no waiting.
Mortise Lock Rekeying and Commercial Locksmith Services for Torrance Businesses
Mortise locks are the workhorses of commercial doors — the rectangular lock body recessed into the door edge, combining a latch, deadbolt, and sometimes a privacy function in one integrated unit. They're common on storefronts along Sepulveda Boulevard, on multi-unit residential buildings, and on older office suites throughout the Del Amo corridor. Rekeying a mortise lock requires removing the entire lock body from the door mortise, disassembling the cylinder, and re-pinning it — a more involved process than a simple knob-lock rekey, but one our experienced technicians handle routinely as part of our commercial locksmith work.
If you manage a property with multiple suites, we can also key locks to a master-key system during the rekeying visit — meaning a single master key opens every door while individual tenant keys work only on their own units. This is a significant upgrade in access control that becomes possible without replacing a single piece of hardware. For any business owner who has had a staff change, a break-in attempt, or simply lost track of how many key copies are out in the world, a commercial rekey is one of the most practical security steps you can take. Call (310) 237-1393 and our team will assess your door hardware, confirm an exact price, and complete the work the same day.
When You're Locked Out or Dealing with an Emergency Locksmith Situation
Sometimes the call isn't planned. A property manager discovers that a former tenant never returned their keys. A homeowner in Walteria realizes mid-evening that the door knob lock on the back door was rekeyed years ago by someone they no longer trust. Or a business owner gets a call at midnight that the front door isn't securing properly after a disturbance. These are genuine emergency locksmith scenarios — not just inconveniences — because an unsecured entry or a key in unknown hands is an active vulnerability.
A1 Torrance Locksmiths answers every call 24 hours a day, every day of the year. Our mobile units are stocked for emergency response, which means we carry the pin kits, cylinder tools, and replacement hardware needed to handle both residential door knob lock rekeying and commercial mortise lock work on the spot. If you're in the middle of a lockout situation, the first sensible step is always to check for a spare key with a trusted neighbor or try other legitimate entry points you have access to — but when none of that applies, our team is the call to make. We verify ownership before any work begins, and we document the service so you have a clear record.
What Determines Your Rekeying Quote — and 25 Services We Provide on Every Call
A fair question when you're weighing a service call is: how much does a local locksmith charge, and what makes one job cost more than another? The honest answer is that several real factors shape the final number. The type of lock matters — a standard door knob lock rekey is quicker than a multi-cylinder mortise lock rekey or a high-security Schlage Primus cylinder that requires a specialized follower tool. The time of day matters — a call at 2 a.m. on a Sunday involves different resource allocation than a scheduled Tuesday morning appointment. Travel distance within the greater Torrance area plays a role, as does whether parts such as additional pin sets or new key blanks are needed beyond a standard rekey. For those asking how much an emergency locksmith costs, the same logic applies — emergency availability has its own factor in the pricing structure. What we commit to in every case is that we confirm the exact price with you before any work begins — no surprise charges appear on the invoice afterward.
Beyond rekeying, here is a specific look at what our trained technicians handle on a typical service call: residential deadbolt rekeying, residential knob and lever rekeying, mortise lock rekeying, master key system setup, high-security cylinder rekeying, new deadbolt installation, mortise lock installation and repair, door knob lock replacement, sliding door lock repair, patio door bar lock installation, garage side door lock service, mailbox lock rekeying, storage unit lock service, padlock rekeying and replacement, smart lock installation and programming, keypad lock installation, door frame and strike plate reinforcement, house lockout response, apartment lockout response, commercial door lockout response, office suite lock change, retail storefront lock service, property management multi-unit rekey programs, file cabinet and desk lock service, and key duplication for newly rekeyed cylinders — all performed mobile, at your location, anywhere in the Torrance area.

Frequently asked questions
Is it cheaper to rekey a lock or replace it entirely — and does rekeying work on any lock?
In nearly every case, rekeying costs less than replacement because the hardware itself stays in place — only the internal pin configuration changes. The savings come from not purchasing new lock hardware and from shorter labor time on standard cylinders. Rekeying works on the vast majority of pin-tumbler locks, including deadbolts, door knob locks, and mortise locks. Locks that use a proprietary or restricted keyway may require a specialist tool or a direct cylinder replacement, which our technicians can assess and quote on the spot before touching anything.
How much does an emergency locksmith cost for a same-day or after-hours rekey in Torrance?
The factors that shape any rekeying quote — lock type, number of cylinders, time of day, and travel distance — apply to emergency calls as well. After-hours and same-day availability involves different resource allocation, so those calls are typically priced differently from a pre-scheduled daytime appointment. What stays constant is our process: we give you an exact, confirmed price before any work begins, so you know the full number and can decide without pressure. To get a firm quote for your specific situation, call (310) 237-1393 — we answer 24 hours a day.
What's the best way to find a reputable locksmith and make sure I'm dealing with a legitimate service?
The most reliable approach is to call directly, ask specific questions about how they verify your ownership of the property before working, and confirm they will provide an exact price upfront before starting. Legitimate technicians always verify that the person requesting service has a right to access the property — they'll ask for ID and may ask for proof of address or tenancy. At A1 Torrance Locksmiths, our trained and insured technicians follow this verification process on every job, residential or commercial, and our mobile dispatch means the person who answers your call is coordinating the same team that shows up — no third-party handoffs.
How many locks should I rekey, and do I have to rekey every lock at once?
You're never required to rekey every lock in a single visit, but there are practical reasons to consider doing them together. If you're rekeying because a key was lost or copied without your knowledge, rekeying only the front deadbolt while leaving the back door knob lock on the old key cuts down the security gain significantly. Our technicians will walk through your door hardware with you, identify which cylinders share a keyway and which don't, and help you decide which combination makes the most sense for your situation. If you want all locks keyed alike — so one key opens everything — we can set that up during the same appointment.
Can you rekey a mortise lock the same day, or do those jobs require a scheduled appointment?
Mortise lock rekeying is a same-day service in most cases. Our mobile units carry the tools and pin assortments needed for the mortise cylinders common in Torrance commercial properties and older residential buildings. The job takes longer than a standard deadbolt rekey because the lock body is removed from the door mortise and disassembled, but our experienced technicians complete it efficiently and without damage to the door or frame wherever possible. If you have an unusual or older mortise lock, calling ahead to describe it gives us a chance to confirm we have the right components on the truck.
I saw a video online showing how to rekey locks myself — is DIY rekeying a good idea?
Rekeying kits exist for common Kwikset and Schlage deadbolts, and tutorial content is widely available. DIY rekeying is possible on straightforward residential hardware if you're comfortable with small mechanical work and have the right follower tool. The risks are real, though: dropped or mis-ordered pins can leave a lock in a state where it doesn't function at all, and a lock that appears to work but has a misaligned pin stack may fail unexpectedly or allow the old key to still operate. For mortise locks, high-security cylinders, or any lock on an exterior commercial door, professional service is strongly advisable — the complexity and the security stakes both increase significantly. Our technicians handle the full range of residential and commercial hardware, so there's no scenario where you'd need to source a specialty kit or risk voiding a hardware warranty.
