A standard builder-grade deadbolt keeps honest people honest, but it can be picked, bumped or drilled by someone with basic tools and a little practice. High security locks are built differently. They use tighter tolerances, hardened inserts that resist drilling, pin designs that defeat picking and bump keys, and restricted keyways so that copies cannot be cut at just any hardware counter. For some Gardena doors, that upgrade is well worth it.
Gardena's housing is a real mix, and that shapes what we recommend. There are 1920s-40s bungalows and Craftsman cottages whose old hardware has outlived its usefulness, large numbers of 1950s-60s stucco homes and dingbat apartments along Western, Normandie and Vermont, and a commercial strip tied to the card clubs and retail on Redondo Beach Blvd. A homeowner, a property manager and a storefront tenant each need something different from a high security lock, and we try to match the product to the actual door and the actual risk instead of selling the most expensive option.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead tech David Shar. We are mobile only, with no storefront, which means the work happens at your door. We look at the door, the frame, the strike and how your keys get used, then install hardware that fits all of it, and we explain the tradeoffs plainly before we start.
How it works in Gardena
- 1
Talk through the problem
Call (323) 997-8867 and tell us what you are protecting and why you want an upgrade. It may be a recent break-in attempt, a lost key you cannot account for, tenant turnover, or simply wanting better protection. This helps us suggest the right grade of lock before we arrive.
- 2
Inspect the door and frame
A strong lock is only as good as what it is mounted in. On site we check the door material, thickness, edge condition, strike plate and frame. Older bungalow doors and thin hollow-core doors in mid-century apartments often need reinforcement to get the full benefit.
- 3
Choose the lock and key system
We go over options such as pick-resistant cylinders, bump-resistant pin designs, drill-resistant hardened inserts and restricted keyways with controlled key duplication. We also discuss whether you want keyed-alike locks across several doors or a separate key for each.
- 4
Install and reinforce
We fit the new hardware cleanly, adding a reinforced strike plate, longer screws or a door-edge reinforcement where the door needs it. Where a door has a vintage look, we work to preserve its appearance as much as practical.
- 5
Test and hand over keys
We operate the lock repeatedly with the door open and closed, check alignment, and make sure the latch and bolt throw fully. You get your keys along with an explanation of how to order additional copies under the restricted system.

What affects the price
- The grade and type of lock chosen, since restricted-keyway, drill-resistant and certified high security cylinders vary widely in cost.
- How many doors or cylinders are being upgraded, and whether they are keyed alike or each on its own key.
- The condition of the door and frame, including whether a reinforced strike, edge reinforcement or other prep work is needed.
- Door type, such as a wood bungalow door, a hollow-core apartment door or a commercial aluminum storefront door, which affects the hardware and labor involved.
- Extra keys and the key control system you want, including restricted blanks and authorization for duplicates.
- Time of day and urgency, since after-hours and emergency calls differ from scheduled daytime work.

High Security Locks across Gardena
Gardena sits just off the I-110 (Harbor Fwy), with Western Ave, Normandie Ave, Vermont Ave, Redondo Beach Blvd and Rosecrans Ave carrying most of the daily traffic. We work throughout ZIP codes 90247, 90248 and 90249, from the older residential blocks to the commercial corridors.
In Moneta, many homes are 1920s bungalows and Craftsman cottages, some with original mortise locks that no longer work. Owners often want modern security without losing the vintage door look, and that is where a carefully chosen high security deadbolt, fitted with a reinforced strike, can do the job. Around Strawberry Park, the stucco homes of the 1950s and 60s often have builder-grade deadbolts that are worn and easy to defeat, making them good candidates for an upgrade.
Along the Western Avenue corridor, dingbat apartments and small multi-unit buildings face heavy tenant turnover and worn hardware. A restricted key system helps a property manager control who can copy keys, and keying units alike for an on-site manager can simplify access. Businesses near the card clubs and along Redondo Beach Blvd have different needs, including commercial-grade cylinders, aluminum storefront doors and panic hardware that often has to be serviced after hours. Near Alondra Park and El Camino College, the mix of homes and rentals brings similar questions about key control.
