Locks in Sylmar live hard lives. The community stretches from the valley floor up into the San Gabriel foothills, and the hardware on its doors, gates, and outbuildings has to deal with dust, sun, shifting frames, and decades of use. A deadbolt that sticks, a key that has to be jiggled, or a padlock fused shut by grit are signs that replacement will serve you better than another repair.

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 shop to drive to. We bring hardware and tools to your property, look at the door or gate in front of us, and replace what needs replacing, whether that is a single deadbolt or every entry point on a newly purchased house.

Lock replacement is not just taking one lock off and putting another on. The right choice depends on the door, the frame, how the property is used, and who has had keys in the past. In Sylmar, that can mean anything from a 1960s tract home with tired knobs, to a gated subdivision with keypads, to a horse property with a tack room that needs a weather-resistant padlock. We talk through the options and install what fits.

How it works in Sylmar

  1. 1

    Call and describe what you have

    Call (323) 997-8867 at any hour. Tell us which doors, gates, or outbuildings are involved, what the current locks are doing, and whether you are replacing because of wear, damage, a move, or a lost key. That helps us bring suitable hardware to the property.

  2. 2

    Inspect the door, frame, and existing lock

    On site, we check the lock, the door edge, the strike, and the jamb. In older foothill homes, settling and past earthquake movement can leave frames slightly out of square, and a new lock will not fix a deadbolt that is fighting a misaligned strike. We spot that before installing.

  3. 3

    Choose the right hardware

    We go over options such as standard deadbolts, higher-security cylinders, handlesets, smart locks, or weather-resistant shrouded padlocks for barns and trailers. You decide based on how the door is used, your budget, and how much convenience you want.

  4. 4

    Remove the old lock and install the new one

    We take out the worn hardware and fit the new lock, adjusting the bore, latch, and strike plate as needed. If the strike or jamb needs realigning so the bolt throws smoothly, we handle that as part of the job.

  5. 5

    Key it to your needs

    New locks can be keyed alike so one key works every door, or keyed separately. If you are replacing locks after a resale or a lost key, new keying means old keys no longer work.

  6. 6

    Test everything and hand over keys

    We operate each lock repeatedly with the door open and closed, check the strike alignment, and confirm every key works. For smart locks or gate keypads, we make sure you know how to set codes and manage access.

What affects the price

  • The number of locks being replaced, from a single deadbolt to every door, gate, and outbuilding on a property.
  • The type and grade of hardware you choose, such as basic deadbolts versus higher-security cylinders, handlesets, or smart locks.
  • Door and frame condition, including whether the strike, jamb, or bore needs realigning or repair, which is common where frames have racked over time.
  • Keying choices, like keyed-alike sets across multiple doors or restricted key systems.
  • Specialty applications such as weather-resistant padlocks for barns and trailers, or work tied into electronic gate keypads.
  • The time of day and location of the call, since we are available 24/7 and travel to you.

Why Sylmar chooses us

  • Fully mobile: we work at your door, gate, or barn, so there is no storefront trip and no need to bring the lock to us.
  • In business since 1987, with owner and lead technician David Shar behind the work.
  • Available 24/7, so a broken lock or a lost key at night does not have to wait for morning.
  • We look at the frame and strike, not just the lock, so you do not pay for new hardware that still sticks.
  • We understand Sylmar property types, from tract homes and gated subdivisions to equestrian properties with outbuildings.
  • We explain the options plainly and let you choose the level of hardware that suits your property.

Lock Replacement across Sylmar

Sylmar is one of the Valley's larger communities by area, and the housing changes as you climb toward the foothills. In 91342 you find 1960s to 1980s tract homes along streets feeding off Foothill Boulevard, Hubbard Street, and Roxford Street, many with original hardware that has been through decades of turning. Those homes often benefit from new deadbolts and entry sets, rekeyed so that previous keys no longer open the door.

In Rancho Cascades and the other newer gated subdivisions, the work often involves more than the front door. A home that has just been resold may need the house rekeyed and the driveway keypad or call-box access reprogrammed so former occupants and contractors no longer have a way in. Newer builds here are also adopting smart locks, which we can install and set up alongside traditional deadbolts.

Around El Cariso and the Olive View foothill district, many properties are larger lots with barns, tack rooms, and detached outbuildings. Santa Ana dust and grit seize ordinary padlocks, so we replace them with weather-resistant, shrouded locks. Sylmar was the epicenter of the 1971 quake and felt the 1994 Northridge quake strongly, so at older homes we often find racked frames where a deadbolt no longer throws. There we realign the strike and jamb, then replace and rekey the lock. Whether you are near Olive View-UCLA Medical Center, El Cariso Park, or just off the I-5, I-210, or SR-14 interchange, call (323) 997-8867.

Lock Replacement in Sylmar — FAQs

How do I know if I should replace a lock instead of repairing it?
Replacement makes sense when a lock is worn, damaged, corroded, or outdated, or when keys have been lost. If the real problem is a misaligned strike or a racked frame, we will tell you, since new hardware alone will not solve that. Call (323) 997-8867 and describe the symptoms.
Can you replace locks at night or on weekends in Sylmar?
Yes. We are a 24/7 mobile locksmith, so you can call (323) 997-8867 at any hour. We come to your property with the tools and hardware needed.
My deadbolt no longer throws all the way. Do I need a new lock?
Not always. In older Sylmar homes, settling and past earthquake movement can leave the door and frame out of alignment. We check the strike and jamb first, realign them if needed, and replace or rekey the lock only if that is warranted.
Can you handle gated properties like those in Rancho Cascades?
We can replace and rekey the locks on the home itself and work on keypad or call-box access for the driveway gate. After a resale, rekeying the house and reprogramming gate access together is a common request.
What kind of padlock is best for a barn or tack room?
Dust and grit are hard on standard padlocks. We recommend weather-resistant, shrouded padlocks for barns, tack rooms, and trailers, and can replace seized ones on equestrian properties around Hubbard and Foothill.
Can all my doors be keyed to one key?
Yes. We can key new locks alike so a single key works for every door, or key them separately if you prefer. Tell us what you want when you call (323) 997-8867.
Do you install smart locks?
Yes, smart locks are an option for replacement, and they are becoming more common in newer Sylmar builds. We can discuss whether one suits your door and how you want to manage access.
Do you have a shop I can visit?
No. Crenshaw Lock Company is fully mobile with no storefront. We come to you anywhere in Sylmar, including the 91342 area.
