Rekeying changes the inside of a lock so that a different key operates it. The old key, whether it belongs to a previous owner, a former employee, a contractor or a lost ring, no longer turns the cylinder. The lock, the finish and the door stay exactly as they are. In San Marino, where so many homes have original hardware worth keeping, that is often the best way to regain control of who has access.

Most people call us after a specific event: buying or inheriting a house, a change in household staff, a lost set of keys, or the end of a long-term rental or contractor arrangement. Others simply realize they have no idea how many copies of their keys exist after decades in one house. Rekeying resets that count to the keys you are holding right now.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar leads our work. We are fully mobile, with no storefront to visit. We come to you with the tools and cylinder stock to do the job at your door, any hour of the day or night.

How it works in San Marino

1
Tell us about the property and the reason
When you call (323) 997-8867, we ask how many doors, gates and outbuildings need to be keyed, what kind of locks are on them, and why you are rekeying. A sale, a staff change and a lost key can each call for slightly different priorities.
2
Inspect each lock on site
We look at every deadbolt, knob, mortise lock and gate lock to confirm it can be rekeyed cleanly. Worn cylinders, mismatched brands, and old mortise sets are identified before any work starts, so you know your options in advance.
3
Re-pin the cylinders
We remove each cylinder, replace the internal pins to match a new key cut, and reassemble it. On original brass mortise hardware we work carefully so the vintage faceplates, escutcheons and handles are not scratched or altered.
4
Key everything alike, if you wish
Many San Marino properties have front, rear, garage, side and garden gate locks. We can re-pin them all to one key, or set up separate keys for different areas, such as one for staff and one for family.
5
Test and hand over new keys
We operate every lock with the new keys, confirm the old ones no longer work, and make sure each door latches and locks smoothly. You get the new keys and can request extra copies on the spot.
6
Discuss upgrades only if they make sense
If a lock is worn out or a door would benefit from a higher-security cylinder or a safe-grade deadbolt, we explain the option. It is your call, and rekeying alone is a perfectly valid result.

Whether you want every lock keyed alike or several separate key groups.
The condition of existing cylinders, because worn or damaged ones may be better replaced than rekeyed.
How many duplicate keys you need cut once the work is done.
The time of day and urgency of the visit, since we are available around the clock.

Lock Rekeying across San Marino

San Marino is a quiet, almost entirely residential city, and its housing stock shapes how we approach rekeying. Many homes near the Huntington Library district are 1920s and 1930s period-revival estates, Spanish Colonial, Tudor and Georgian, with solid-wood doors and original mortise hardware. Owners usually want to keep that character, which makes rekeying a natural fit: the old brass stays, and the access changes.

In the Lacy Park neighborhood and along streets off Huntington Drive, Sierra Madre Blvd and San Gabriel Blvd, properties are often large, with several exterior doors, a garage, and side or garden gates. A single lost key or a change in household staff can affect all of them at once. We regularly think in terms of whole-property rekeys, bringing every entry point, including gates, onto one key or a clear key plan. Homeowners in 91108 also often have safes or discreet smart-lock systems, and we can work around those so everything operates together.

We also serve the Mission District along Huntington Drive, where modest neighborhood-scale businesses sit near El Molino Viejo and the Crowell Public Library. Whether you live off Del Mar Ave or Los Robles Ave or near the Huntington itself, we come to you. Call (323) 997-8867 any time.
