A standard deadbolt from a hardware store keeps honest people honest. A high security lock is built for a different problem: someone who is willing to pick, bump, drill, or pull a cylinder out of the door. In Northridge, that conversation looks different depending on where you live. A student-rental owner near CSUN worries about keys that get copied and never returned. A homeowner in a 1960s ranch tract house wants hardware that outlasts decades of wear. A horse property owner in Sherwood Forest needs gates and outbuildings that stand up to weather as well as tampering.
High security hardware typically combines several features: tighter pin or sidebar mechanisms that resist picking and bumping, hardened inserts that frustrate drilling, and restricted keyways so keys cannot be duplicated at a corner kiosk. The cylinder is only part of the picture, though. A strong cylinder in a weak door frame, with a short strike screw, still fails. We look at the whole door assembly, not just the lock you asked about.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar built the business on fieldwork. We are mobile only, with no storefront, so every job begins with a conversation by phone and then a visit to your actual door. That matters in Northridge, where the age and condition of the door and frame vary a great deal from one block to the next.
How it works in Northridge
- 1
Talk through your situation
Call (323) 997-8867 and tell us what you are protecting and what worries you. Is it a front door, a rental unit, a gate, or a detached outbuilding? Do you want one key for everything, or separate access for different people? These answers shape which hardware makes sense.
- 2
Inspect the door, frame, and strike
We come to you and look at the door, the frame, the strike plate, and the existing lock. In older Northridge tract homes, we often check whether decades of settling have left the bolt misaligned or the wood around the strike weakened. Reinforcing a weak spot can matter as much as the cylinder.
- 3
Choose the right level of protection
We explain the options in plain terms: pick- and bump-resistant cylinders, drill-resistant inserts, and restricted key systems that control who can copy your keys. We recommend what fits your door and your risk, not the most elaborate product on the shelf.
- 4
Install and reinforce
We install the new lock, fit longer strike screws or a reinforced strike where needed, and make sure the bolt throws smoothly and fully. If the door has shifted, we correct the alignment so the lock does not bind.
- 5
Key setup and testing
We cut and test the keys, and for multi-lock properties we can key locks alike so one key works across them. We cycle every lock several times while you watch, and we explain how to order additional keys through the restricted system.

Walk-through and care tips
Before we leave, we show you how everything works and how to keep it working, including lubrication guidance suited to your lock type and what to do if a key is ever lost.

What affects the price
- The grade and type of lock you choose, since restricted-keyway and drill-resistant models vary widely in construction and cost.
- How many locks are involved, whether one front door, a block of apartment units, or a barn, tack room, and gate set.
- The condition of the door and frame, including whether settling or wear requires realignment, a new strike, or reinforcement.
- Whether you want keys that are keyed alike across several locks or a master-key arrangement with separate levels of access.
- The number of keys you need and how the restricted key system handles future duplicates.
- The time of day and location of the visit, since we operate 24/7 and some jobs are requested outside normal hours.
Why Northridge chooses us
- Fully mobile service: we bring the tools and hardware to your Northridge door, with no storefront trip required.
- In business since 1987 under owner and lead tech David Shar, so the person guiding your decision has long field experience.
- We evaluate the door and frame, not just the cylinder, which matters in older homes where settling can undermine good hardware.
- We recommend the level of security that matches your actual risk rather than steering everyone to the priciest option.
- We can handle mixed jobs, such as residential deadbolts, apartment rekeys, and rural-style gate and outbuilding locks, in a single visit.
- Available 24/7, so a break-in repair that needs stronger hardware does not have to wait for business hours.
High Security Locks across Northridge
Northridge is a mix of building types, and each one calls for a different approach. The 1950s and 60s ranch tract homes in the Devonshire residential area often still carry their original hardware, and many sit on doors and frames that have moved since the 1994 earthquake, which was centered in neighboring Reseda. A deadbolt that binds in a settled frame is a common complaint. We can realign the bolt, reinforce the strike, and install a high security cylinder so the door both operates smoothly and resists tampering.
Around CSUN, the student-rental apartments along Reseda Blvd, Zelzah Ave, and nearby streets see constant turnover, which means keys multiply. A property owner preparing for fall move-in may want a block of units rekeyed to restricted key systems so tenants cannot casually copy keys. Northridge Village and the newer condos have their own needs, often involving shared entries and individual unit doors that benefit from consistent, controlled keying.
In Sherwood Forest, the horsekeeping estates present a different challenge: barns, tack rooms, and driveway gates exposed to weather and easy to overlook. We can replace those locks with durable hardware and key them alike so one key handles the whole property. Whether you are in ZIP 91324 near Reseda Blvd and Nordhoff St, 91325 along Devonshire St, 91330 near the university, or elsewhere in 91327 and 91328, call (323) 997-8867 and we will come to you.
