Rekeying is the simplest way to cut off everyone who might still hold a key to your home. Previous owners, tenants, contractors, a former roommate, a neighbor who once watered the plants: any of them could have a copy. Rather than replacing hardware, we reconfigure the lock cylinder so it works with a new key, and the old key becomes a useless piece of brass. In Sylmar, this comes up most often right after a home purchase, when a new owner wants a clean slate on day one.

Sylmar is a big, varied community. Across the valley floor you find 1960s through 1980s tract homes, and as the streets climb toward the San Gabriel foothills you get older modest houses, large-lot equestrian properties with barns and outbuildings, and newer gated subdivisions. Each of these has different locking needs: a tract home may have a front deadbolt, a knob lock and a couple of side-door locks, while a horse property may have a dozen padlocks and several doors, all of which someone may want keyed alike.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, under owner and lead technician David Shar. We are fully mobile, with no storefront to visit. We bring the tools and key blanks to your door, work through the locks on the property, and test every one before we leave. If a lock is worn, damaged or not worth rekeying, we will tell you plainly and explain the options.

How it works in Sylmar

  1. 1

    Call and describe the property

    Phone (323) 997-8867 and tell us what you have: how many exterior doors, whether there are side gates, garage entries, barns or outbuildings, and whether the locks are standard deadbolts, knob sets or smart locks. That helps us bring the right pinning kits and key blanks.

  2. 2

    We come to you

    We are 24/7 and fully mobile, so we meet you at the property, whether that is a new home you just closed on or a house where you want to cut off an old key right away. We confirm the scope with you before starting.

  3. 3

    Inspect each lock

    Before rekeying, we check that each lock operates smoothly. A cylinder that sticks, a latch that does not fully retract, or a deadbolt that no longer lines up with its strike is worth catching now. Sylmar homes with a history of settling or frame racking sometimes need the strike or jamb adjusted before a lock will work reliably.

  4. 4

    Rekey the cylinders

    We remove the cylinders, replace the pins to match a new key, and reassemble them. Where it makes sense, we key multiple locks to the same key so you carry one key for the front door, back door and garage entry.

  5. 5

    Test and hand over keys

    We try the new keys in every lock, confirm the old keys no longer turn, and check that doors latch and deadbolts throw fully. You receive the new keys and we can cut extras on the spot.

What affects the price

  • The number of cylinders to be rekeyed, since each lock takes its own time and pinning.
  • Whether you want everything keyed alike or separate keys for different doors and buildings.
  • The type and condition of the hardware, including higher-security cylinders, smart locks, or worn locks that may be better replaced.
  • Extra work found during inspection, such as realigning a deadbolt strike or adjusting a door that has shifted in its frame.
  • Padlocks and outbuilding locks on larger properties, which can add to the count and may call for weather-resistant replacements.
  • The time of day you call and how far into the foothills we travel, since we serve 24/7 on a mobile basis.

Why Sylmar chooses us

  • Serving Los Angeles and Ventura County since 1987, led by owner David Shar, so the work is done by someone with decades in the trade.
  • Fully mobile: we do the work at your door, with no shop visit and no leaving the house unsecured.
  • We rekey rather than replace whenever the existing hardware is sound, which keeps your original locks and avoids unnecessary spending.
  • We are candid about when a lock should be replaced instead, such as a worn cylinder or a deadbolt that cannot be made to throw reliably.
  • Experience with foothill and equestrian properties, including keyed-alike setups across a house, gates and barn locks.
  • Available 24/7, so a rekey after a late closing, a lost key or a move-out can be handled when you need it.

Lock Rekeying across Sylmar

In the 91342 ZIP code, rekeying requests tend to follow real estate and life changes. In Rancho Cascades, a gated resale often means two jobs: the new owner wants the house rekeyed, and the driveway keypad or call-box may need its access codes reset or its malfunction looked at. Because gate and entry access can be shared with former residents, rekeying the house and updating access go together.

Head toward El Cariso and the streets near Hubbard Street and Foothill Boulevard and you find larger lots, horse properties and outbuildings. Barn and tack-room padlocks take a beating from Santa Ana dust and grit, and they tend to seize. We can swap them for weather-resistant, shrouded locks and key them to match the house if you prefer. Closer to the Olive View foothill district, older homes sometimes have deadbolts that no longer throw cleanly after decades of settling and the memory of the 1971 and 1994 earthquakes. We can realign the strike and jamb and then rekey the entry so it works smoothly.

Whether you live near Veterans Memorial Community Regional Park, off Roxford Street, or up near the foothills and the Wildlife Learning Center, we come to you. Sylmar sits at the junction of the I-5, I-210 and SR-14, so we can reach you from the freeways without you needing to travel anywhere. Call (323) 997-8867.

Lock Rekeying in Sylmar — FAQs

What is the difference between rekeying and changing locks in Sylmar?
Rekeying changes the internal pins of your existing lock so a new key works and old keys do not. Changing locks replaces the hardware itself. If your locks are in good shape, rekeying is usually the simpler option. Call (323) 997-8867 and we can advise based on what you have.
Should I rekey after buying a home in Sylmar?
It is a smart step. You cannot know how many copies of the old keys exist among previous owners, tenants, agents or contractors. Rekeying makes every old key obsolete, and we can do it the day you take possession.
Can you rekey the house and my barn or tack-room locks together?
Yes. On equestrian properties we can key house doors, gates and outbuilding padlocks alike, or keep them separate, depending on how you want to manage keys. Seized padlocks can be replaced with weather-resistant, shrouded models.
My deadbolt barely turns or does not throw all the way. Can rekeying fix that?
Not always. In older foothill homes, shifted frames can misalign the bolt and strike. We can realign the strike and jamb, then rekey the lock. If the cylinder itself is worn out, we will recommend replacement.
Do you handle gated subdivision keypads and call-boxes?
We can help with driveway gate keypad and access issues on gated properties like those in Rancho Cascades, alongside rekeying the house. Describe your setup when you call (323) 997-8867 so we can plan the visit.
Can smart locks be rekeyed?
Many smart locks still have a physical key cylinder that can be rekeyed, but the electronic side is separate. Credentials and codes should also be reset after a sale or move. Tell us the brand and model when you call.
Do I need to be home during the rekey?
Someone authorized should be present or arrange access so we can reach each lock and hand over the new keys. If you are unsure how to coordinate, talk to us at (323) 997-8867.
Do you have a shop I can visit in Sylmar?
No. Crenshaw Lock Company is fully mobile and available 24/7. We bring everything to your property, so there is no storefront to drive to.
