A lock rarely fails all at once. It starts with a key that has to be jiggled, a deadbolt that sticks when the weather turns, or a latch that no longer catches. In La Verne those signs show up on very different kinds of doors: a hundred-year-old Craftsman near D Street, a rental a few blocks from the University of La Verne, a newer foothill home on the way toward Marshall Canyon. Each one calls for a different kind of replacement, and the right answer is not always a new deadbolt off the shelf.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile, so there is no storefront to visit. We bring the tools and hardware to your property, look at the door in front of us, and replace what actually needs replacing.
Lock replacement is different from rekeying. Rekeying changes the internal pins so old keys stop working and the existing hardware stays. Replacement means the hardware itself comes off and new hardware goes on, which makes sense when a lock is worn out, damaged after a break-in attempt, a style you want to change, or simply too old to trust. We will tell you honestly which of the two fits your situation, because sometimes the cheaper option is the right one.
How it works in La Verne
- 1
Call and describe the door
Phone us at (323) 997-8867 any time of day or night. Tell us what the lock is doing, what kind of door it is, and whether it is an entry door, a garage service door, a gate or a hangar. That helps us bring the right hardware.
- 2
Inspect the existing hardware
On arrival we look at the lock, the strike plate, the latch and the door itself. Misaligned doors and loose frames are a common reason locks wear out early, and we point those out before installing anything new.
- 3
Choose the right replacement
We go over options with you: standard deadbolts, handle sets, smart or keypad locks, or mortise hardware for older doors. You decide on the grade and finish, and whether you want all locks keyed alike.
- 4
Remove and install
We take off the old hardware and fit the new lock, adjusting the bore, latch and strike so it throws smoothly. On older doors we work carefully to avoid damaging original woodwork.
- 5
Test and hand over keys
We operate every lock repeatedly with the door open and closed, confirm the bolt fully engages, and give you all your keys. If a smart lock is part of the job, we walk you through its setup.

What affects the price
- The type of lock chosen, from a basic deadbolt to a high-security cylinder, a keypad lock or a smart lock
- The number of locks being replaced and whether you want them keyed alike on a single key
- Door condition, including whether the bore, latch area or frame needs adjusting or repair for the new lock to fit properly
- Older or specialty hardware, such as mortise sets on historic doors, which may need specific parts or careful fitting
- Whether the work is a scheduled visit or an after-hours, overnight or emergency call
- Site type, since hangar roll-doors, padlocks and gates involve different hardware than a standard residential entry door

Lock Replacement across La Verne
La Verne has more variety in its doors than most people expect. In Old Town La Verne, around D Street and Bonita Ave, many homes are early-1900s Craftsman and period houses that still have original mortise locks or skeleton-key doors. Owners often want better security without losing the character of the door, so we look at fitting modern, sturdier hardware that suits the era, or upgrading the mortise set itself, and we take care with the old wood.
Near the University of La Verne, student rentals tend to change hands on a term schedule. Landlords and tenants in the area around 91750 often ask for fresh locks at the start of a term, especially when old keys have gone missing or past occupants have never returned them. Where a simple rekey will do, we say so; where hardware is worn or broken, we replace it.
Further north, newer foothill developments climbing toward Marshall Canyon Regional Park have their own needs, such as upgrading builder-grade locks or adding keypad entry. Over at Brackett Field, general-aviation hangars rely on padlocks and roll-door locks that take a lot of wear from weather and use. Whether you reach us from Foothill Blvd, Arrow Hwy, Wheeler Ave or off the SR-210 and SR-57, we are mobile and ready to come to you.
