From rekeys and repair to access control and ongoing support, we protect the everyday operation of homes, businesses, and managed properties throughout the Bay Area.
Request serviceWe bring deep hardware knowledge to the service calls that matter—without overcomplicating the solution.
Rekeys, repairs, master key systems, door closers, panic hardware, and commercial openings.
Security hardware, access control guidance, property turnover support, and scheduled maintenance.
A local Bay Area team that can support the system after the project is complete.
A lock problem is rarely just about the key. We look at the lock, latch, frame alignment, surrounding hardware, and how the opening is used—then explain the simplest good solution.

Diagnose the whole opening and correct the part that is actually causing trouble. We repair quality hardware when repair makes sense and adjust the surrounding hardware so the lock can work correctly.
Change who has access without replacing every lock. We can organize straightforward rekeys or plan more controlled key systems for homes, businesses, and managed properties.
Upgrade security with the right level of technology—not more complexity than the building needs. Don’s supports selected smart locks and practical access-control hardware.
Keep original, valuable, or hard-to-replace hardware in service through careful evaluation, mechanical repair, refinishing, and proper reinstallation.
Don’s coordinates the hardware that makes a commercial opening safe, accessible, secure, and serviceable—from door control and life-safety requirements to electrified hardware, access interfaces, and ADA applications.

Push plates, touchless switches, sensors, and operator packages matched to the opening.
Choose who can enter, when they can enter, and how. We help select, install, set up, and support smart locks that fit the door and the way the building is managed.
We install premium mortise locks and architectural hardware in new and remodeled homes, and we preserve quality existing pieces when replacement is not the best answer. Don’s protects the fit, finish, and function—then leaves the hardware ready for years of daily use.
Take the hardware apart carefully and keep every useful component organized.
Remove dirt, failing coatings, paint, and corrosion without destroying important detail.
Correct wear and mechanical problems where practical.
Restore the selected color and surface character.
Reassemble and reinstall so the hardware looks right and works correctly.
Sometimes the lock is worn. Sometimes the door is out of alignment. Sometimes the wrong hardware was installed. Don’s looks at the whole opening before recommending what to repair, adjust, refinish, or replace.
That saves good hardware, avoids unnecessary work, and creates a result that lasts longer.
