What we do most

What we do most in San Marcos

Half the homes here were built after the mid-1990s and whole neighborhoods are newer than that, so most of our week is fresh keys and keypad locks on doors that never had either.

Also here when you need us

Built for newer homes

A new house in San Elijo Hills or a resale in Rancho Dorado comes with more keys floating around than most owners realize. The builder's construction key, the copies the trades carried for months, the lockbox the listing agent used, and whatever the previous owner handed to a dog walker. The lock hardware is usually fine. The pins inside it are the problem.

A move-in rekey resets every exterior cylinder to one new key in a single visit. If you want the front door to stop needing a key at all, a keypad or app deadbolt goes on the same trip, and we rekey its backup cylinder so the old key does not quietly still work.

For the business parks along SR-78

The tilt-up and logistics buildings going up in San Marcos Business Park and AXIS Logistics Park hand new tenants a ring of keys with no record of who else has copies. We put the suite on a fresh key or a proper master key chart, sort out the storefront cylinders and the rear panic bar, and set up fob or card readers for the doors that see shift changes and contractors.

Property managers and HOA boards get one point of contact and one invoice, whether it is a tenant turnover or a pool gate that needs resident fobs.

How a visit works

    You hear the range and the service call fee on the phone. No mystery fees when the van shows up.

  3. ID check, then the work

    We confirm you belong there, confirm the price, and get to it. Hardware and keys are on the van.

  4. Walkthrough and invoice

    Every key tested, every code set, an itemized invoice in your inbox, and labor covered by our warranty.
