A deadbolt is one of the most effective upgrades you can make to a door, but only when it is fitted properly. A strong bolt in a loose, poorly bored door, or a strike plate held by short screws, can fail the first time someone puts a shoulder or boot to it. Installation is as much about the door and frame as the lock itself.
Pomona has a wide mix of doors. Victorians and Craftsman homes in the historic districts often have old wood doors with original mortise hardware. Tract homes in Phillips Ranch have standard hollow or solid-core doors with factory bores. Student rentals and mid-century stucco courts near the campuses may have worn or mismatched hardware that has been rekeyed, or not, over many tenants. Each needs a different approach.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner David Shar. We are fully mobile, with no storefront to visit. We bring tools and hardware to you at any hour, assess the door, explain your options plainly, and install the deadbolt so it operates smoothly and holds up.
How it works in Pomona
- 1
Tell us about the door
Call (323) 997-8867 and describe the door: material, whether it already has a deadbolt, and whether you want single or double cylinder. Mention if it is an older home or a rental with several doors. That helps us bring the right hardware.
- 2
On-site assessment
We come to you and inspect the door, the bore holes, the edge, and the frame. We check thickness, condition, and whether the jamb is solid enough to support a new bolt. On older doors we tell you if a mortise lock or historic hardware needs a different solution.
- 3
Choose the right deadbolt
We explain the difference between single-cylinder (thumb turn inside) and double-cylinder (key on both sides). Double-cylinder suits doors with glass nearby but can be a concern in emergencies, so we talk through the tradeoffs and what fits your household.
- 4
Install and reinforce
We fit the deadbolt, set the bolt alignment, and install the strike plate with long screws that reach the framing. If the door or jamb is weak, we discuss reinforcement options so the new lock is not the strongest part of a weak door.
- 5
Test and hand over keys
We operate the lock repeatedly with the door open and closed, confirm smooth throw, and hand over keys. We can key the new deadbolt to match your existing locks when the hardware allows.

What affects the price
- Whether you need a new installation in a bare door or a replacement of an existing deadbolt, since a new bore takes more work.
- The door material and condition, such as solid wood, hollow-core, metal, or an older door that needs repair around the bore.
- Single- versus double-cylinder, and the grade and brand of deadbolt you choose.
- Frame and strike reinforcement needs, including jamb repair or longer-screw upgrades.
- The number of doors in one visit, which matters for landlords and multi-unit properties.
- Keying preferences, such as matching existing keys or keying several locks alike.
Why Pomona chooses us
- Fully mobile and available 24/7, so installation can happen at your door rather than requiring a trip to a shop.
- In business since 1987, with experience across everything from tract-home cylinders to older wood doors.
- We look at the door and frame, not just the lock, because a deadbolt is only as strong as what it is mounted in.
- We say when a deadbolt is not the right answer, such as with original mortise hardware on a historic home that can be serviced or rekeyed instead.
- Multi-door visits for landlords and property managers, with consistent keying handled in one trip.
- Clear explanations of single versus double cylinder so you choose with the tradeoffs in view.
Deadbolt Installation across Pomona
Pomona's housing stock makes deadbolt work far from one-size-fits-all. In the Lincoln Park Historic District, Queen Anne Victorians and Craftsman homes often carry original brass mortise locks and skeleton-key sets. Adding a deadbolt there means working carefully with old wood, and sometimes servicing or rekeying the existing mortise lock instead of drilling a new hole. In Ganesha Hills, period revival homes from the 1920s to 40s often have solid doors that take a quality deadbolt well.
Over in Phillips Ranch, 1970s and 80s tract homes and newer stucco subdivisions generally have standard residential bores, so upgrading or replacing a deadbolt is usually straightforward. Near Cal Poly Pomona and Western University of Health Sciences, student rentals and stucco apartment courts see frequent tenant turnover, and landlords often want several doors fitted or rekeyed in one visit before move-in. The same goes for lofts and brick buildings in the Downtown Pomona Arts Colony and the Westmont area.
We serve ZIP codes 91766, 91767, 91768, and 91769, reaching homes and businesses off I-10, SR-60, SR-57, SR-71, Holt Ave, and Garey Ave. Whether you are near Pomona Valley Hospital Medical Center, Antique Row on 2nd Street, or the Fairplex grounds, call (323) 997-8867 and we will come to you.
