Most of the locks in Winnetka are the ones the builder installed. Walk the streets around Winnetka Ave and Sherman Way and you will find 1950s and 60s tract homes with original or builder-grade locksets that have been turned tens of thousands of times. Those locks were made to keep an honest door closed, not to resist someone who knows how to pick, bump or drill a cylinder. A high security lock is built differently: tighter tolerances, hardened inserts, more complex pin or sidebar designs, and keys that are harder to copy.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has watched the same pattern repeat in the west Valley: a lock fails, gets replaced with whatever is cheapest, and the weakness stays. We are fully mobile, so there is no shop to visit. We come to the property, look at the door, the frame, the strike and the existing hardware, and recommend something that fits how you actually live or manage the building.

High security is not always the right answer for every door, and we will say so. A rear patio slider and a front entry need different thinking, and an apartment complex with frequent tenant turnover needs a different key strategy than a single-family home. The goal is a lock that makes sense for the door, the building and the budget, installed correctly so it works for years.

How it works in Winnetka

  1. 1

    Talk through the problem and the doors

    Call (323) 997-8867 any hour. We ask what you are trying to solve: a break-in concern, tenant turnover, lost keys, a failing original lockset, or a key that has been copied too freely. We also ask about the door type and how many locks are involved.

  2. 2

    On-site assessment

    A mobile technician comes to the property and inspects the door, frame, strike plate and existing hardware. A strong cylinder in a weak frame is only half a fix, so we check whether the door itself can support the upgrade.

  3. 3

    Choose the lock and key system

    We explain the options in plain terms: pick-resistant and bump-resistant cylinders, drill-resistant hardened inserts, and restricted keyways where key duplication is controlled. For condos and apartments we discuss keying to match a common-entry key or setting up a master key arrangement.

  4. 4

    Installation and reinforcement

    We install the lock, adjust alignment so the bolt throws smoothly, and reinforce the strike or frame where it makes sense. Builder-grade doors in older tract homes often need a little attention to fit properly.

  5. 5

    Key setup and testing

    We cut and test every key, confirm the lock operates smoothly from both sides, and walk you through how key control works so you know how additional keys are obtained.

  6. 6

    Follow-up guidance

    Before we leave, we point out any other doors or locks worth attention, such as side gates, garage entry doors or mailbox locks, so you can plan upgrades on your own schedule.

What affects the price

  • The grade and brand of lock: pick-, bump- and drill-resistant models vary widely in construction and in how much protection they provide.
  • Whether you want a restricted keyway with controlled key duplication, which changes both the cylinder and how new keys are ordered.
  • The number of doors or cylinders involved, which matters for a single home versus several units in a Vanowen or De Soto apartment complex.
  • The condition of the door and frame, since reinforcement or repair of a worn strike or loose jamb adds work beyond the lock itself.
  • Whether the locks must be keyed alike, matched to a condo common-entry key, or fit into a master key system.
  • Time of day and urgency, since after-hours or emergency calls are handled differently from scheduled upgrades.

Why Winnetka chooses us

  • Fully mobile service: we come to your door with the tools and hardware to assess and install, and there is no storefront you need to visit.
  • Available 24/7, so a security upgrade after a break-in or a lock failure does not have to wait for business hours.
  • In business since 1987, with owner David Shar leading the work and bringing decades of experience with older Valley housing stock.
  • Honest recommendations: if a standard quality deadbolt or a simple rekey solves your problem, we will tell you rather than sell you more lock than you need.
  • We look at the whole entry, including the door, frame and strike, because a high security cylinder is only as strong as what surrounds it.
  • Experience with multi-unit properties, including rekeying several apartments at once and matching condo deadbolts to building common-entry keys.

High Security Locks across Winnetka

Winnetka sits in the central-west San Fernando Valley, and its housing tells you a lot about its locks. In the Winnetka Ave and Sherman Way residential core, many mid-century tract homes still carry their original front-door locksets. After decades of use, those locks wear out, and replacing one is a natural moment to move up to a pick- and drill-resistant model rather than another builder-grade set. A homeowner in 91306 with a failing original lockset can often have it replaced and rekeyed in a single visit.

Along the Vanowen St multifamily corridor and the De Soto Ave apartment district, the picture is different. These are 1970s and 80s complexes and mid-century buildings with frequent tenant turnover, which means keys are constantly in circulation. A property manager dealing with several move-outs may want restricted keys so former tenants and their friends cannot simply copy a key at a hardware counter. Condo owners face another need: a unit deadbolt that works with the building's common-entry key, plus the shared mailbox and entry locks that HOAs manage.

We work throughout the area, from the streets near Winnetka Recreation Center and Prairie Street Elementary to the commercial stretch near Winnetka Bowl on Vanowen St and the retail around the former Winnetka Drive-In site. Whether you are off Roscoe Blvd, Saticoy St, Mason Ave or Victory Blvd, or close to Northridge Fashion Center and US-101, our mobile technicians come to you at any hour. Call (323) 997-8867.

High Security Locks in Winnetka — FAQs

What makes a lock high security?
High security locks use tighter manufacturing tolerances, hardened components, and more complex internal designs to resist picking, bumping and drilling. Many also use restricted keyways so keys cannot be casually duplicated.
Do I need a high security lock for my Winnetka tract home?
Not necessarily for every door, but the front entry is a good candidate, especially if the original lockset is worn. We will assess your doors and tell you honestly what makes sense. Call (323) 997-8867 to discuss it.
Can you upgrade several apartment units at once?
Yes. Property managers along Vanowen St and De Soto Ave often have us rekey or upgrade multiple units after move-outs. We can key units individually or set up a system that suits your building.
Can a high security deadbolt match my condo's common-entry key?
In many cases yes. We can rekey or select a cylinder so your unit works with the building's common-entry key, though compatibility depends on the building's existing system. Call (323) 997-8867 and we will help sort it out.
What is the difference between rekeying and replacing a lock?
Rekeying changes the internal pins so old keys stop working while keeping the same hardware. Replacing swaps the hardware itself. If a lock is worn out or weak, replacement with a high security model is usually the better route.
Will a high security lock protect a weak door?
Only partly. Thieves often kick in a weak frame rather than attack the cylinder, so we check the door, jamb and strike plate and recommend reinforcement where needed.
Do you offer emergency service for lock upgrades?
Yes. We are available 24/7 and fully mobile. If you have had a break-in or lost keys, call (323) 997-8867 at any hour.
How do I get extra keys for a restricted keyway?
Restricted systems control duplication, so extra keys are ordered through authorized channels, usually requiring proof of authorization. We explain the process when we set up your lock.
