Lock, rekey, and key-system service
Start with the lock symptom, then inspect the full opening.
Elwin services these commercial lock families across San Jose, Santa Clara, and nearby Bay Area cities. Every repair starts with the symptom the business noticed.
Lock-function changes
A storeroom-function lock stays locked on the outside, so the door relocks behind every entry. A classroom-function lock lets staff lock or unlock the outside lever with a key. A passage lock latches but never locks. A privacy lock locks from the inside for restrooms and single-occupant rooms. Server rooms and IT closets often move to storeroom-function levers to keep key control auditable.
Cylinder repair, replacement, and rekeying
Service for cylinders that are worn, damaged, or hard to operate, plus authorized rekeying when keys, staff, or occupancy change. Keyed-alike service can put a group of doors on one key for authorized users.
Interchangeable-core service
Service for small-format interchangeable cores and large-format interchangeable cores, often abbreviated SFIC and LFIC. Common problems include a core that spins in its housing and a control key that stops operating the core. Elwin also services high-security commercial cylinders.
Master-key and keyed-alike system service
Elwin reviews master-key and keyed-alike requests from authorized property contacts. Service covers locks already running on a master-key or keyed-alike system, cylinder changes within them, and rekeys tied to an authorized access change.
Storefront lock hardware
Narrow-stile deadlatch and paddle hardware on aluminum storefront doors. Typical symptoms include a deadlatch that sticks and a paddle that turns without retracting the latch.
Tenant-turnover rekey programs
Recurring rekey service at move-out for property managers and HOAs, keyed-alike suites, and key control for managed buildings. Elwin confirms the authorized property contact before any keys change.
Keyed-alike padlock fleets
One authorized key can operate a fleet of keyed-alike padlocks across gates, utility rooms, and roof hatches. Elwin services and rekeys padlock fleets for commercial and managed properties.

Jordan and his crew have been fantastic to work with. They’re quick to respond, easy to coordinate with, and always get the job done right. It’s clear they care about their work and take pride in helping their customers.
We’ve worked with Elwin Security across multiple office buildings for both access control and building security improvements. They helped us install and manage systems like Kisi, ButterflyMX, and Brivo, while also assessing the security of our buildings and installing maglocks and other hardware upgrades.
Elwin Security is great to work with. They are responsive, provide quality service, and offer reasonable prices. I highly recommend them!
