We handle both, and we quote the full price before anyone drives out. A storefront lock replacement in Claremont typically runs $145 – $285 depending on the hardware, and a commercial lockout from a locked business runs $95 – $165.

Why Preston Locksmith & Security Is Claremont’s Preferred Commercial Locksmith Company
We’re Commercial Locksmith specialists, not a general handyman service that dabbles in locks. Since 2008, Preston Locksmith & Security has worked on storefronts, offices, and medical suites across Claremont, and we’re part of the Relay Home Co. family. Every location is independently owned and operated, and every job is covered by The Relay Visibility Guarantee: a written price before work begins, a live trackable arrival time, before-and-after photos, and a written guarantee on every repair. No anonymous techs. No vague hourly estimates. No bill that grows between the quote and the invoice.
Kevin Yoon leads our Claremont crews. The tech who shows up is background-checked, uniformed, and trained on Medeco, Mul-T-Lock, Baldwin, and Sargent commercial hardware just as much as everyday Schlage and Kwikset. Claremont property managers don’t have time to explain a commercial door’s locking system over the phone twice. We listen once, name the lock brand and the likely failure based on the door vintage, and arrive with the right parts already in the van.
Mortise Lock Replacement in Claremont
Mortise lock replacement in Claremont is the repair we do most often on Yale Avenue storefronts, because those original wood-frame commercial doors predate modern cylindrical locks. A mortise lock is the rectangle-shaped lock body recessed into the edge of the door, not the round deadbolt knob most people picture. Replacing one means pulling the old body out of the door edge, matching the replacement’s faceplate dimensions and backset, and reinstalling a like-for-like ANSI Grade 1 assembly. In Claremont, a mortise lock replacement typically runs $220 – $395 including the new body and labor, with the exact price confirmed in writing before we dispatch.
We’ve handled this specific door type enough times to know what we’re walking into. An older Village wood door has settled; the strike plate has shifted; the internal springs have worn; the cylinder is holding, but barely. We bring replacement mortise bodies sized for standard 2-1/2-inch and 2-3/4-inch backsets, plus faceplates in common finishes.
What the Replacement Actually Involves
We remove the old mortise lock body, confirm the cylinder type, and determine whether the existing cylinder can be rekeyed into your master key system or needs replacement. If the door has shifted out of alignment, we re-align the strike plate so the latch throws cleanly without forcing. Then we install the new body, test the deadbolt and latch through a full cycle, and show you the before-and-after photos before we leave.
No-Drilling Policy for Village Storefronts
We don’t drill a Claremont commercial lock unless it’s genuinely destroyed beyond repair. Drilling a Mortise lock in a historic door frame creates splinter damage that costs more to fix than the lock itself. If we can pick or shim the lock open, we will, and we’ll say so before any work starts.
Replace Commercial Door Lock in Claremont
Our Door Lock Repair - Claremont service covers everything from a worn cylindrical deadbolt on an office suite to a full narrow-stile aluminum storefront lock swap. The job varies hard by building type. On a newer office suite near Indian Hill Boulevard, the lock is usually a standard cylindrical deadbolt or lever handle, and replacement runs $145 – $285. On an older Village storefront with a mortise body, the work takes longer and runs $220 – $395. Both prices include the hardware and labor, and both are confirmed in writing before a tech is dispatched.
We stock common commercial lock replacements for Claremont’s two dominant door vintages: original wood-frame doors and modern aluminum storefront doors. That means we don’t have to order a part and leave your business door unsecured for three days.
Replacement vs. Repair: Which One Do You Need?
If the lock body is intact but the key turns rough or the cylinder is worn, a rekey or cylinder replacement usually solves it for less than a full lock swap. If the latch won’t retract, the deadbolt won’t throw, or the faceplate is pulling away from the door edge, the lock body itself has failed and replacement is the honest fix. We’ll tell you which one applies to your door, with the price difference named in plain numbers.
Commercial Door Lock Brands We Replace
We regularly replace Kwikset, Schlage, Yale, Baldwin, Sargent, and Medeco commercial hardware in Claremont. If your building uses a restricted keyway like Medeco or Mul-T-Lock, we coordinate the new cylinder through the existing key control system so you don’t lose the ability to track who has keys.
Trusted Brands We Service in Claremont
We service and install Medeco high-security cylinders, Baldwin mortise locks, Yale commercial levers, Kwikset deadbolts, Schlage electronic locks, Mul-T-Lock telescoping pins, Sargent interchangeable cores, and Abloy disc-detainer cylinders. For Claremont businesses, we keep common replacement parts stocked locally, which means a storefront on Yale Avenue or an office on Foothill Boulevard doesn’t wait on a parts shipment from a distributor. If your commercial door uses a less common brand, we’ll source the exact part and confirm the price before ordering.
Common Commercial Locksmith Problems We See in Claremont Homes
- Worn mortise lock bodies in historic Village storefronts. The original wood doors along Yale Avenue are often 60 to 90 years old, and the internal lock springs eventually fatigue. We see binding latches, stuck deadbolts, and keys that turn but won’t retract the bolt.
- Narrow-stile aluminum storefront door misalignment. The newer suites near Indian Hill Boulevard and Foothill Boulevard use aluminum frame doors that shift with daily foot traffic. A misaligned strike plate makes the lock bind, and the fix is often adjustment plus a fresh cylinder, not a full door replacement.
- Ad-hoc key control that turns into a security audit problem. When a Claremont multi-tenant building has gone through three property managers, nobody knows who holds copies of the master key. We set up a proper master key system with key tracking, so the next manager inherits a clean ledger instead of a mystery.
- Storefront locks damaged by attempted break-ins or forced entry. Claremont businesses near the Village and the Claremont Colleges see periodic after-hours tampering. We replace damaged cylinders, repair forced latches, and can upgrade vulnerable doors to high-security restricted keyways.

FAQs About Commercial Locksmith in Claremont
Yes. Every commercial locksmith quote for Claremont is a written line-item price confirmed before a tech is dispatched, and it is the exact price on the invoice. We don’t use teaser trip fees or reveal the real cost after arrival. If the job scope changes because the door condition differs from what was described, we call you with the revised written price before any additional work starts.
In most cases, yes. We pick or shim commercial locks open about 90% of the time before considering drilling, including mortise locks on older Village doors. Drilling is a last resort only when the lock is seized or damaged beyond repair, and we always tell you the stated no-drill policy before we start. Call (409) 405-4485 and we’ll walk you through what we can do for your specific door.
An older Village storefront with a wood-frame mortise lock takes about 60 to 90 minutes and requires a like-for-like mortise body replacement, typically $220 – $395 including hardware. A newer aluminum suite lock with a cylindrical deadbolt takes about 30 to 45 minutes and runs $145 – $285. The difference is the door construction and lock body type, not labor padding. We quote both scenarios by phone, in writing, before dispatch.
Yes. We set up master key systems for Claremont offices, medical suites, and mixed-use buildings, using Medeco, Mul-T-Lock, or Sargent restricted keyways so keys can’t be duplicated at a hardware store. Each tenant gets a key that works their own door, and you get a master that works all of them, with a key ledger showing who holds copies. Pricing starts around $300 and depends on door count and cylinder type.
Every tech arrives in a Preston uniform with company ID, and you get a live trackable arrival time on your phone before they leave the shop. The written price is already in your hands, and the tech matches the photo and name we sent. No subcontracted strangers, no third-party contractors.
