Commercial rekeying typically runs $25–$75 per cylinder depending on lock type. Master key system design and installation varies by the number of locks and hierarchy complexity.

Emergency commercial lockouts run $100–$200 depending on lock type and time of day. We provide written quotes before starting any job, call (800) 422-5625 for a site-specific estimate.

Can you expand an existing master key system in a San Jose office without replacing all the locks?

In most cases, yes. If the existing system uses a standard hierarchy and the locks are in good condition, we can cut additional keys and add new cylinders that fit within the current structure. For restricted or proprietary keyways — common in larger North First Street tech campuses, we verify authorization before proceeding. Bring documentation from the original installation if available. We don't expand master key systems in ways that compromise their access architecture.

How often should a San Jose business rekey its locks?

As a minimum: whenever an employee with physical key access leaves, whenever keys go missing, and whenever you take over a new commercial space. Beyond that, we recommend an annual lock audit for businesses with high staff turnover or multiple keyholders, particularly in high-traffic San Jose commercial areas like Santana Row and Downtown SJ where the risk of key duplication is elevated. Our locksmiths can perform an audit and flag any cylinders showing wear that may compromise security.

San Jose Commercial Districts We Serve

North First Street Tech Corridor

San Jose's densest concentration of tech campuses, corporate headquarters, and R&D facilities runs along the North First Street corridor from Alviso down through North San Jose. Properties here typically run complex master key hierarchies across multiple buildings, require electronic access control with audit-log capability for compliance purposes, and have high staff turnover that drives frequent rekeying. For restricted or proprietary keyways, common in purpose-built tech campuses, we verify authorization before any key duplication or system expansion takes place.

Downtown San Jose

Downtown San Jose hosts a mix of multi-tenant office towers, government buildings, retail ground floors, law firms, medical offices, and the SJSU campus district. Multi-tenant buildings require master key systems where individual tenants hold suite access and building management holds higher-level grand master access without having unrestricted keys to tenant spaces. Lease changes and tenant turnover make commercial rekeying a regular service here, we can rekey within existing master key hierarchies, so the rest of the building's access architecture stays intact.

Santana Row and Retail West

Santana Row and the adjacent West San Jose retail corridor combine high-end retail, restaurant operations, and residential above commercial, a property type with specific access needs. Retail properties see high staff turnover, require tight key control for loss prevention, and often need rekeying at shift manager or seasonal staff changes. We provide rekeying programs tied to staff turnover schedules and can install high-security cylinders in high-traffic retail entries where standard Grade 3 hardware is insufficient.

Convention Center and Airport District

The McEnery Convention Center and surrounding hospitality properties, hotels, event venues, and conference facilities, manage access across large numbers of rooms, service areas, and public/staff separation points. Mineta San José International Airport and the logistics and aviation services businesses surrounding it operate with strict access control requirements and high security hardware needs across perimeter and personnel access points. We design and install systems that meet these requirements and can service existing hardware without disrupting operations.

Berryessa and East San Jose Industrial

Berryessa's commercial zones and the broader East SJ industrial corridor host warehousing, distribution, manufacturing, and light industrial operations, property types where perimeter security, heavy-duty padlocking, loading dock access control, and shift-worker key management are the primary needs. We supply and install high-security commercial hardware rated for industrial applications and can design master key systems covering personnel entry points, equipment areas, and supervisor access tiers.

Access Control System Installation

We install and configure keypad, key fob, card reader, and biometric access systems for San Jose commercial properties. Systems can be zoned by entry point with full access logging, giving you a complete record of who accessed which area and when. Electronic systems let you revoke credentials instantly without rekeying when staff leave, and scale from a single-door installation to a multi-zone enterprise deployment across multiple buildings.

• Keypad and PIN systems for smaller commercial properties and single-entry points

• Card reader and fob systems for multi-tenant buildings, tech campuses, and high-traffic commercial properties

• Biometric access for properties requiring the highest level of entry control

• Access logging and audit trail for compliance-sensitive industries including legal, medical, and financial

Master Key System Design and Installation

A master key system gives different keyholders different levels of access without issuing blanket keys, a property manager holds a grand master, department heads hold masters for their zones, and individual staff hold keys only to their own spaces. We design, install, and expand master key systems for San Jose multi-tenant office buildings, tech campuses, retail centers, and industrial parks.

If your existing system uses a standard hierarchy and locks are in good condition, we can add new cylinders and cut additional keys that fit within the current structure, no full lock replacement required. For restricted or proprietary keyways, we verify authorization before proceeding and bring documentation of our authorized dealer status.

Commercial Rekeying

Commercial rekeying changes the internal pins of an existing lock cylinder so previous keys no longer work, the hardware stays in place and the cost is significantly lower than full replacement. We rekey all common commercial lock types: deadbolts, mortise locks, cylindrical locks, padlocks, and cabinet locks.

Rekeying triggers for San Jose businesses: whenever an employee with key access leaves, whenever keys are lost or unaccounted for, when you take over a new commercial space with unknown key history, and as part of scheduled security audits for properties with high staff turnover.

• Commercial rekeying $25–$75 per cylinder depending on lock type

• Written quote provided before any work begins — no hidden charges

• Annual lock audits available for properties with high turnover or multiple keyholders

High-Security Commercial Lock Installation

Standard commercial Grade 2 or Grade 3 hardware is adequate for lower-risk applications, but many San Jose commercial properties, tech campuses with sensitive IP, medical offices, legal firms, financial institutions, and high-value retail, require locks that provide documented key control, forced-entry resistance, and protection against unauthorized key copying.

We install Medeco, Mul-T-Lock, and ASSA Abloy high-security commercial locks featuring hardened steel inserts, anti-pick pins, anti-drill plates, and patented keyways that prevent key duplication without authorization. We are authorized dealers for all three manufacturers.
