A high security lock is built to resist the methods that defeat ordinary hardware: picking, bumping, drilling and forced removal. Better pin designs, hardened inserts and restricted keyways make the cylinder much harder to attack and keep key duplication under control. In Sylmar, where properties range from tract homes to gated subdivisions to large equestrian lots, the right upgrade depends on how your property is actually used.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar and our team work entirely on a mobile basis. There is no storefront to visit. We bring the hardware to you, look at your doors, frames and gates in person, and install on the spot.

A lock is only as strong as the door and frame holding it. Sylmar sits at the center of some of the region's most significant earthquake history, and many older homes have frames that have shifted over the decades. We check that the door, strike and jamb are sound before we fit a premium cylinder, because a strong lock in a racked frame will not perform as it should.

How it works in Sylmar

  1. 1

    Talk through your needs

    Call (323) 997-8867 and tell us what you want to protect: a front door, a gated entry, a barn, a detached workshop or a business. We ask about current locks, who has keys and any past problems so we can suggest suitable hardware.

  2. 2

    Inspect the door and frame

    We come to your property and examine the door, jamb, strike plate and surrounding structure. On older foothill homes we look for settling or racking that stops a deadbolt from throwing cleanly, since that affects which lock will work well.

  3. 3

    Choose the security level

    We explain the differences between pick-, bump- and drill-resistant cylinders and between restricted and standard keyways. You decide how much protection and key control fits your property and routine.

  4. 4

    Install and correct the hardware

    We fit the new high security lock, and where needed realign the strike, adjust the jamb or reinforce the plate. For outbuildings we can use weather-resistant, shrouded designs suited to dust and exposure.

  5. 5

    Test and hand over keys

    We cycle the lock repeatedly, confirm smooth operation from both sides, and give you the keys along with guidance on key control and any follow-up copies.

What affects the price

  • The grade and style of high security cylinder or deadbolt you choose, including whether it uses a restricted keyway.
  • How many doors, gates or outbuildings are being upgraded in one visit.
  • Whether the door or frame needs repair, reinforcement or realignment before the lock will work properly.
  • Whether you want existing locks rekeyed to match, or entirely new hardware throughout.
  • Weather-resistant or shrouded designs for barn, tack-room and trailer use versus standard interior-door hardware.
  • Number of additional restricted keys needed and whether integration with a keypad, gate or smart lock is involved.

High Security Locks across Sylmar

Sylmar climbs from the valley floor into the San Gabriel foothills, and security needs change along the way. In gated communities like Rancho Cascades, residents often deal with driveway keypads, call-boxes and front doors that all need attention after a home sale. A high security deadbolt with a restricted key gives new owners better control over who holds copies, and we can pair that with rekeying the house so previous keys no longer work.

Around El Cariso and the equestrian properties off Hubbard Street and Foothill Boulevard, locks face harsh conditions. Santa Ana dust and grit can seize ordinary padlocks on barns and tack rooms, so weather-resistant, shrouded high security padlocks and cylinders are a practical choice. In the Olive View foothill district, older homes may have frames that have shifted since the 1971 Sylmar and 1994 Northridge earthquakes, so we realign strikes and jambs as part of the job.

Whether you are in ZIP code 91342 near Olive View-UCLA Medical Center, close to Veterans Memorial Community Regional Park, or off the I-5, I-210 or SR-14 corridors, we come to you. Call (323) 997-8867 any time of day or night.

High Security Locks in Sylmar — FAQs

What makes a lock high security?
High security locks use features that resist picking, bumping and drilling, such as hardened components and specialized pin designs. Many also use restricted keys that cannot be freely copied at a hardware store.
Do you have a shop in Sylmar I can visit?
No. We are fully mobile and have no storefront. We come to your home, ranch or business anywhere in Sylmar. Call (323) 997-8867 to arrange a visit.
Can you upgrade locks on my barn or tack room?
Yes. For equestrian properties we can install weather-resistant, shrouded locks that handle dust, grit and moisture better than standard padlocks.
My deadbolt barely throws in my older home. Will a new lock fix it?
Often the problem is a shifted frame rather than the lock itself. We inspect the door, strike and jamb, realign them as needed, and then fit the new lock so it operates smoothly.
Can you help after buying a home in a gated community like Rancho Cascades?
Yes. We can install high security locks, rekey the house so old keys stop working, and help with keypad or call-box access concerns. Call (323) 997-8867 to discuss your situation.
Are you available at night or on weekends?
Yes, we operate 24/7. If you need a secure lock after a break-in or lockout, you can reach us at any hour.
Will high security locks work with my smart lock or keypad?
It depends on your setup. We can often add a high security cylinder or deadbolt alongside or as part of an electronic system. We will review your door and equipment in person.
Does a high security lock make my door impossible to break into?
No lock is unbeatable. A high security lock greatly raises the difficulty of common attacks, but strong doors, frames and strike plates matter too, which is why we inspect all of them.
