Installing a lock sounds simple until the door, the frame and the property all have opinions. In Sylmar, a single day's work might mean a new deadbolt on a freshly hung door in a 1970s tract home, a keyed entry set on a converted garage, or a weather-resistant padlock setup for a barn at the edge of the foothills. Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and we come to you because we are fully mobile, with no storefront to visit.
A good installation is more than drilling two holes. The door has to be thick enough and properly prepared, the bore and latch holes need to be cleanly cut, and the strike has to land in solid framing rather than thin trim. In Sylmar, where the 1971 quake and the 1994 Northridge quake left many older homes with settled or racked frames, we pay close attention to whether a new lock will actually line up and throw smoothly once it is in place.
We work with homeowners, renters with landlord permission, property managers and small-acreage owners. Whether you are finishing a remodel, adding a lock where none existed, or upgrading to a smart lock in a newer build, we help you choose hardware that suits the door and how you live. Call (323) 997-8867 any hour and we will talk through what you need.
How it works in Sylmar
- 1
Tell us about the door and the goal
When you call, we ask what kind of door it is, whether it is new or already drilled, and what you want the lock to do. Exterior, interior, garage side door, barn or gate each call for different hardware, so a few quick questions save a second trip.
- 2
Inspect the door, frame and surroundings
On arrival we check door thickness, material, existing bore holes and the condition of the jamb. In older foothill homes we look for racking or settling that could keep a new deadbolt from lining up, and we tell you plainly if the frame needs attention first.
- 3
Select appropriate hardware
We go over grade, finish, keying and style with you. Options may include standard deadbolts, keyed entry sets, high-security cylinders, keypad locks or smart locks. For outbuildings we recommend weather-resistant, shrouded designs that handle dust and exposure.

Prepare the door and install
We mark and cut the bore and edge holes cleanly, set the latch and strike, and reinforce the strike area where it makes sense. The lock is mounted square so the bolt extends fully without forcing the door.
- 5
Test, key and walk you through
We operate the lock repeatedly with the door open and closed, check how it behaves in the frame, and cut or set the keys or codes. Before we finish, we show you how everything works and how to maintain it.

What affects the price
- The type of lock chosen, from a basic deadbolt to a high-security cylinder or a smart lock with electronic components.
- Whether the door is already drilled or needs new bore and edge holes cut, which changes the amount of work involved.
- The condition of the door and frame, including any strike reinforcement or realignment needed after settling.
- The number of locks and whether they should be keyed alike so one key works throughout the property.
- Special hardware for outbuildings, such as shrouded or weather-resistant padlocks and hasps for barns and tack rooms.
- Time of day and location, since we are available 24/7 and after-hours service can differ from a scheduled daytime visit.
Why Sylmar chooses us
- Fully mobile service: we bring tools, hardware and key-cutting capability to your Sylmar door instead of asking you to visit a shop.
- Since 1987 in the Los Angeles area, led by owner and lead technician David Shar, so we have seen how local homes and doors actually behave.
- Attention to frame condition, because quake-affected and settled frames are common here and can undermine even good hardware.
- Practical advice on matching the lock to the property, whether a tract home, gated subdivision, or equestrian lot with outbuildings.
- Available 24/7, so a door that cannot be secured tonight does not have to wait until morning.
- Clear explanations of options and tradeoffs, without pushing hardware you do not need.
Lock Installation across Sylmar
Sylmar stretches from the valley floor up into the San Gabriel foothills, and the housing changes along the way. Around Foothill Boulevard, Hubbard Street and Roxford Street you find many 1960s to 1980s tract homes where owners are adding deadbolts, replacing worn entry sets, or securing newly built additions. In 91342, we also see older modest homes whose frames have shifted over decades, so we check alignment before committing to new hardware.
Newer gated subdivisions such as Rancho Cascades bring a different set of needs: keypad and smart-lock installs on entry doors, side gates and garage access, often alongside electronic driveway gates and call-boxes. Up toward El Cariso and the Olive View foothills district, larger lots and semi-rural properties often have barns, tack rooms and detached outbuildings. Dust and grit in the dry season are hard on ordinary padlocks, so we lean toward weather-resistant, shrouded locks for those spots.
Whether you are near Olive View-UCLA Medical Center, close to El Cariso Community Regional Park, or just off the Newhall Pass interchange where I-5, I-210 and SR-14 meet, we come to you at any hour. Call (323) 997-8867 and tell us where you are in Sylmar and what needs a lock.
