Lock Installation & Repair is the core commercial locksmith service that keeps your business secure, compliant, and operational. Whether you need a fresh Lock Installation & Repair for a new tenant build-out or emergency Lock Installation & Repair after a break-in, this page explains exactly what the service covers, what drives the quote, and how to take the right next step before you call. Mobile technicians are available 24 hours a day where service areas allow — read on to understand scope, pricing, and honest boundaries.
What This Service IS — and What It Is NOT
This service covers the physical installation, replacement, and repair of commercial-grade locking hardware on doors, frames, and openings in business, retail, office, and light industrial settings. That includes cylindrical lever sets, mortise locksets, rim and vertical-rod exit devices, door closers, deadbolts rated for commercial use, and supporting hardware such as strike plates and reinforcement kits.
What IS included:
- Installing new commercial lever sets, knobsets, or deadbolts (storeroom function, entry function, classroom function, etc.)
- Replacing worn or damaged mortise lock bodies and trim
- Repairing or replacing mechanical exit devices (rim-style, surface vertical rod, concealed vertical rod)
- Installing or adjusting door closers
- Reinforcing strike pockets and frames — using listed reinforcement kits when the door or frame is part of a fire-rated assembly, as required to maintain the assembly’s fire listing
- Cutting and fitting new keys to installed hardware
- On-site assessment before work begins on complex or high-security openings
What is NOT included (out of scope):
- Electrified hardware wiring, power supplies, raceways, or power transfer hinges. We can install the physical body of an electric strike or electromagnetic lock, but connecting it to power, programming access logic, running low-voltage wiring, or tying into fire alarm or life-safety panels requires licensed low-voltage or electrical contractors and may require permits under IBC/NFPA 101. Many jurisdictions mandate specific release hardware (request-to-exit devices, fire alarm release) for maglocks — that integration is outside standard locksmith scope.
- Full Access Control system design, networking, or software configuration.
- Structural door or frame replacement (a door shop or general contractor handles that).
- Work on USPS master-keyed mailbox locks, GSA containers, or federally restricted hardware.
- Cosmetic finish work, painting, or welding.
Who This Service Is FOR — and Who It Is NOT For
This service fits business owners, facility managers, property managers, and tenants who need mechanical commercial locks installed, replaced, or repaired on standard commercial openings. It’s right for you if:
- You’re opening a new space and need hardware on every door.
- A lock is broken, worn, or was damaged in a break-in attempt.
- You’re upgrading from residential-grade hardware to commercial-grade.
- A door closer is leaking, slamming, or not latching the door.
- You need an exit device repaired or replaced to restore egress compliance.
This is NOT the right service if:
- You need a full Master Key & Rekeying system designed across dozens of openings — that’s a dedicated project with its own scope.
- You need wired electronic access control, card readers, or networked locking — start with an Access Control consultation.
- You want a full Security Assessment before deciding what hardware to install.
- Your building requires a licensed general or electrical contractor for the work involved.
How We Do It: On-Site Lock Installation & Repair Process
- Verification & authorization. The technician confirms your identity and legal authority over the property before any work begins. Expect to show ID and proof of ownership, lease, or management authorization.
- Opening assessment. The technician inspects the door, frame, existing hardware, and hinge condition. For fire-rated assemblies, the label is checked to confirm any replacement hardware and reinforcement kits maintain the rating.
- Scope & quote. You receive a detailed quote covering the service call fee, labor per opening, and parts — before any work starts. Complex openings (mortise sets, exit devices, closers, high-security cylinders) are quoted individually with specific part costs.
- Installation or repair. Work proceeds only after your written or verbal approval. The technician installs, adjusts, and tests the hardware, confirming the latch engages, the closer speed is correct, and the key operates smoothly.
- Walk-through & keys. You receive all keys, a brief orientation on the hardware function, and any maintenance notes. If additional work is recommended (rekeying to a master system, adding closers to other doors, etc.), it’s quoted separately — no surprise add-ons.
Pricing for Lock Installation & Repair — How Our Pricing Works
Every job begins with a $45 service call fee that covers technician dispatch and travel to your location. This fee applies regardless of whether you proceed with the work — it is never waived and is never described as “free.”
Labor and parts are quoted separately, per opening or per unit of hardware:
- Standard commercial lever set or deadbolt (swap on existing prep): Labor $95–$175 per opening during business hours, plus the cost of the hardware itself.
- Fresh install (new door prep required): Labor $150–$250 per opening during business hours, plus hardware.
- Mortise lock replacement or repair: Labor $175–$300+ per opening, depending on the lock body, trim, and condition of the mortise pocket.
- Exit device (rim, surface vertical rod, concealed vertical rod): Labor $200–$350+ per device, plus the device cost. Concealed vertical rod devices and devices requiring modifications to the frame are at the higher end.
- Door closer install or replacement: Labor $95–$200 per closer, plus the closer.
- After-hours / emergency surcharge: Add approximately $50–$100+ to the labor ranges above. Total after-hours jobs typically fall in the $145–$325+ range per opening before parts.
Important: High-security cylinders, restricted keyway hardware, custom finishes, and multi-point locking systems are assessed and quoted explicitly before work begins — they fall outside the standard ranges above. The technician will never begin work on complex or high-cost items without your approval of a detailed, itemized quote.
Parts pricing depends on the brand, grade (ANSI/BHMA Grade 1 vs. Grade 2), and function specified. The technician carries common commercial hardware on the van; specialty items may need to be ordered, which the technician will discuss during the quote phase.
Real-World Lock Installation & Repair Scenarios
1. Retail Storefront — Broken Mortise Lock
A boutique owner arrives to find the front door mortise lock won’t retract the latch. The technician inspects the mortise body, finds a broken lever tail piece, and replaces the lock body and trim on-site. Because the storefront door is not part of a fire-rated assembly, standard commercial mortise hardware is appropriate. The owner also asks about a Maintenance Plan to catch wear before the next failure.
2. Office Build-Out — Multiple Openings
A property management company is preparing a five-suite office floor for new tenants. Each suite needs a storeroom-function lever set on the entry door and passage-function levers on interior doors. The technician preps doors that lack the correct cutout, installs all hardware, and keys each suite independently. The manager plans to bring the floor under a Master Key & Rekeying system once all tenants sign leases.
3. Warehouse — Exit Device Replacement
A warehouse manager reports that the rim exit device on a rear fire exit is no longer latching. The technician replaces the exit device with a matching ANSI/BHMA-rated unit and verifies the door’s fire label. The new device is tested for free egress and proper latching. The manager is referred to Door Hardware & Exit Devices for additional openings and to Industrial & Institutional Locksmith services for the high-security interior cages.
4. Medical Office — After-Hours Break-In Repair
An office manager discovers a forced-entry attempt on a back door at 10 PM. The frame’s strike pocket is damaged. The technician arrives after hours, installs a listed strike reinforcement kit (required because the door and frame carry a fire-rating label), replaces the damaged deadbolt, and secures the opening. The manager schedules a follow-up Security Assessment to evaluate all perimeter openings.
5. Church — Upgrading Residential Hardware to Commercial Grade
A church board realizes their sanctuary doors still have residential-grade knobs that don’t meet ADA or commercial egress standards. The technician replaces them with Grade 1 commercial lever sets in the correct function (classroom function for controlled access, passage function for secondary exits). The board also discusses Key Duplication & Key Management to better track who holds keys.
6. Property Manager — Tenant Turnover Hardware Swap
A Property Management Locksmith client needs locks changed between tenants on a three-unit strip mall. The technician swaps cylinders on existing commercial lever sets, cuts new keys, and confirms all hardware operates correctly. The manager opts to keep the old cylinders for future rekeying rather than replacing entire locksets.
7. Restaurant — Door Closer Adjustment and Safe Concern
A restaurant’s front door closer is slamming shut, creating a safety hazard for guests. The technician adjusts sweep and latch speeds, and replaces a leaking backcheck valve. During the visit, the owner mentions the floor safe isn’t locking properly — the technician refers them to Safe & Vault Services for a separate appointment with the appropriate tooling.
When to Call — and When This Isn’t the Right Service
Call when:
- A commercial lock is broken, jammed, or needs replacement.
- You’re fitting out a new space and need hardware installed.
- A door closer or exit device needs repair or replacement.
- You need after-hours emergency lock repair to secure a compromised opening.
Stop — this may not be us:
- Electrified hardware integration: If you need electric strikes or maglocks wired to power, connected to access control panels, or tied into fire alarm systems, a licensed low-voltage or electrical contractor is typically required. Many jurisdictions require permits and specific release hardware (request-to-exit, fire alarm shunt) for electromagnetic locks under IBC and NFPA 101. We can install the physical hardware body, but wiring and system integration must be handled by appropriately licensed professionals.
- Fire-rated assembly modifications: We use listed hardware and reinforcement kits on fire-rated openings. If the door or frame itself needs replacement or structural modification, a fire-door assembly contractor should be engaged.
- GSA, USPS, or federally restricted locks: These require authorized dealer or government channels — they are outside our scope.
- Large-scale access control or security system design: Start with an Access Control consultation or a Security Assessment rather than a hardware install call.
- Safes and vaults: Separate service with different tooling — see Safe & Vault Services.
Frequently Asked Questions — Lock Installation & Repair
What does this service cover?
It covers the mechanical installation, replacement, and repair of commercial-grade locks, exit devices, door closers, and supporting strike hardware on business doors and frames. It does not cover electrified hardware wiring, access control system programming, or structural door/frame replacement.
What affects the quote?
The main cost drivers are: whether the opening has existing hardware prep or needs a fresh cutout, the grade and type of hardware (a mortise lock costs more than a cylindrical lever), the number of openings, whether the work is during or after business hours, and whether fire-rated assemblies require listed reinforcement kits. Complex or high-security items are assessed and quoted individually before work starts.
What should I have ready?
Have proof of identity and authorization for the property (lease, ownership document, or management letter). Know how many openings need work, whether the doors are fire-rated, and whether you have a hardware preference or brand standard. If you have existing keys or a master key system, have a sample key available for the technician.
How do I confirm the right service path?
Call and describe the hardware issue, the type of door (storefront, hollow metal, wood), and the number of openings. The dispatcher can help determine whether standard lock installation and repair is the right call, or whether you need a dedicated service such as Master Key & Rekeying, Access Control, or a Security Assessment. If the job turns out to be more complex on-site, the technician will re-quote before proceeding.
