A1 LOS ANGELES LOCKSMITH
Locksmith Service

Rekey & Lock Change

Moving into a new place on Wilshire Boulevard, a rental in Silver Lake, or a home in the San Fernando Valley all share one security blind spot: you have no real way of knowing how many copies of your key are floating around. Previous tenants, old landlords, contractors, or whoever held a spare before you could still have access. A rekey or full lock change closes that gap immediately — without the guesswork. At A1 Los Angeles Locksmith, our mobile team comes directly to your door, anywhere in the Los Angeles area, and handles the job on the spot so you can feel secure in your space the same day.

Rekey or Full Lock Change — Which One Does Your Situation Actually Require?

Rekeying is the process of reconfiguring the internal pin stack inside your existing lock cylinder so that your old key no longer works and a new key does. Because the hardware shell stays in place, it is generally faster and involves fewer parts than a full replacement. It is the right call when the lock itself is in good mechanical shape, you simply need to invalidate old keys, and the existing hardware meets your security needs. A door knob lock on a bedroom or a deadbolt on a solid-core door can almost always be rekeyed rather than replaced. The result: no one holding a previous copy of your key can walk in.

A full door lock change makes more sense in several specific scenarios: the cylinder is worn or damaged, you are upgrading from a basic builder-grade knob to a mortise lock or a high-security deadbolt, you want keypad or smart-lock functionality, or the existing hardware simply does not match the security level a Los Angeles neighborhood warrants. Busy corridors like those around MacArthur Park or older apartment buildings in Koreatown frequently have aging hardware that has been rekeyed so many times the mechanism itself needs retirement. Our technicians assess the condition of your existing locks on-site and give you a straight recommendation — not an upsell.

Mortise Lock Installation, Door Knob Lock Replacement, and Every Service In Between

Our mobile lock change service covers a wide range of residential and commercial hardware. Here is a specific look at what we handle on a single visit: mortise lock installation and replacement, deadbolt installation (single and double cylinder), door knob lock replacement, lever-handle lock replacement, smart lock and keypad lock installation, Schlage and Kwikset cylinder rekeying, high-security cylinder upgrades, master key system setup, rekey locks for apartments and condos, rekey after tenant turnover, lock change after a break-in, lock change after a lost or stolen key, lock change after a roommate dispute, electronic lock reprogramming, Defiant lock change code reset and cylinder rekey, Honeywell door lock change code reset, master lock change combination service for padlocks and gate locks, gate lock installation and replacement, mail box lock replacement, garage door lock replacement, sliding door lock upgrade, window lock installation, storage unit lock change, multi-point lock system service, and commercial lock change for office and retail entry doors. That list covers the most common calls we receive across Los Angeles, but if your hardware is not on it, call us — if it locks, we work on it.

When a customer in Hollywood Hills calls because a contractor still has a key, or a property manager in Culver City needs six units rekeyed before new tenants arrive, the process is the same: our technician arrives with a fully stocked mobile unit, assesses the hardware, confirms the price, and gets to work. For commercial lock change jobs — storefronts, offices, warehouses — we carry commercial-grade cylinders and mortise lock bodies rated for high-traffic doors. We do not treat a commercial call as an afterthought; those sites often have code requirements for egress hardware, and our experienced technicians factor that in.

What Determines the Cost of a Rekey Lock or Lock Change Service in Los Angeles?

We are often asked how much does a locksmith cost in Los Angeles, and the honest answer is: it depends on a set of real, measurable factors. The type of hardware matters most — rekeying a standard Kwikset knob takes different materials and time than installing a mortise lock on a heavy commercial door. The number of locks on the property is the next variable; rekeying one deadbolt is a different scope than rekeying every entry point in a six-unit building in Echo Park. Time of day matters because a 3 a.m. emergency locksmith call draws on after-hours resources. Travel distance across a metro area as spread out as Los Angeles is also factored in. Finally, parts: if you are upgrading cylinders or adding a smart lock, the hardware itself is part of the quote.

None of those factors are hidden from you. Before any work begins, our technician gives you an exact price — confirmed on the spot, no surprise charges when the invoice comes. We also do not charge for the estimate itself when we are already on-site. If you are wondering whether it is cheaper to replace locks or rekey, the answer usually favors rekeying when the existing hardware is sound, but the total cost comparison only makes sense once a technician has seen the actual locks. Call (631) 380-4138 and we can talk through the variables before we even roll a truck.

24/7 Emergency Locksmith Response Across Los Angeles — Including Mortise Lock Emergencies

Security situations do not wait for business hours. A broken mortise lock on a Koreatown storefront at midnight, a snapped key in a deadbolt in Venice at 6 a.m., or a lost house key after a long shift in Downtown LA — all of these are calls we take seriously around the clock. People often ask how quickly a locksmith can arrive, and in a city as traffic-variable as Los Angeles, we give realistic ETAs based on current conditions rather than promises we cannot keep. What we can promise is that a trained, insured technician is dispatched immediately, arrives with the parts most commonly needed for both residential and commercial lock change situations, and works to resolve the issue on the first visit.

Emergency locksmith cost near Los Angeles is shaped by the same factors described above, with the addition of after-hours service timing. We are transparent about that before any work starts. What you will not encounter is a bait-and-switch price at the door. Our technicians are experienced with the full range of Los Angeles housing stock — 1920s bungalows with antique mortise lock hardware in Hancock Park, mid-century apartment buildings in Westwood, modern mixed-use buildings in Arts District — and they carry the parts to match. If you are in a situation right now, do not wait: call (631) 380-4138, available 24/7, and we will get someone moving toward you.

Frequently asked questions

Is it cheaper to replace locks or rekey — and how do I decide?+

Rekeying is almost always the lower-cost option when the existing lock is mechanically sound, because you are paying for labor and new pins rather than new hardware. A full lock change becomes the better investment when the cylinder is worn, the security rating is insufficient, or you want to upgrade to a mortise lock, a smart lock, or a high-security deadbolt. The real answer depends on the condition and type of your specific locks. Our technician assesses them on-site and explains the tradeoffs before you commit to anything.

How much does a locksmith cost in Los Angeles for a standard rekey or lock change?+

The total depends on the type of lock (a basic door knob lock rekey differs significantly from a mortise lock installation), the number of locks being serviced, the parts required, the time of day, and travel distance across the Los Angeles area. What does not vary is our process: we confirm an exact up-front price before any work begins, so there are no surprises on the final bill. Call (631) 380-4138 for a same-day assessment.

How much will an emergency locksmith cost at 2 a.m. in Los Angeles?+

After-hours emergency locksmith calls do carry a time-of-day factor that is part of the honest pricing conversation, but you will know the exact amount before our technician starts. The emergency locksmith cost near you in Los Angeles is shaped by the same variables as a daytime call — lock type, parts needed, travel distance — plus the after-hours component. We never quote one price over the phone and present a different one at your door.

Can AAA do locksmith services like rekeying or a full lock change?+

AAA's roadside assistance program is focused on vehicle lockouts and automotive situations. For residential or commercial rekeying, mortise lock installation, door lock change services, or any work on your home or business entry hardware, you need a dedicated locksmith team. A1 Los Angeles Locksmith handles both automotive and property locksmith work, so one call to (631) 380-4138 covers every scenario.

How do I reset a Defiant lock change code or a Honeywell door lock change code?+

Defiant and Honeywell electronic locks each have a manufacturer-defined reset sequence for changing the access code, and the process varies by model. In some cases the cylinder itself also needs to be rekeyed to match new keys. Our technicians are experienced with electronic and smart lock hardware and can handle the full reset — code change, cylinder rekey, or both — in a single visit. If the lock's programming has been compromised or the unit is malfunctioning, we can also assess whether a replacement is the smarter path.

How quickly can a locksmith arrive in Los Angeles, and do you really come to me?+

Yes — we are fully mobile, meaning our technician drives to your location with a stocked service vehicle. We do not have a shop you need to visit. Arrival time across Los Angeles varies with real-time traffic, which in a city this size can mean the difference between 20 minutes and 45. We give honest ETAs when you call, not optimistic guesses. For emergency calls, dispatch happens immediately. Reach us any time at (631) 380-4138 — we answer 24 hours a day, seven days a week.
