Installing a lock where none existed sounds simple, but the door decides everything. A new solid-core door, a side gate, a converted garage entry, or a casita addition each needs a different approach to boring, backset, strike placement, and reinforcement. In Granada Hills, where homes range from 1950s and 60s ranch tracts to mid-century Eichler houses and foothill properties, the right installation depends on the door in front of us, not a one-size kit.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar leads the work. We are fully mobile, so there is no shop to visit. We bring the hardware, drilling tools, and finishing supplies to your driveway and do the installation on site, any hour of the day or night.

Whether you just hung a new front door, added a back entry, or want a proper deadbolt where there is only a knob, we focus on a clean fit, smooth operation, and a lock that is actually secured to the frame rather than just sitting in the door.

How it works in Granada Hills

  1. 1

    Talk through the door and your goal

    Call (323) 997-8867 and tell us what the door is made of, whether it is new or prefinished, and what you want: a deadbolt, a keyed handleset, a keypad, or a gate lock. That helps us bring suitable hardware.

  2. 2

    Inspect the door and frame on site

    We check door thickness, material, edge condition, and the frame. A solid wood or steel door, a hollow-core interior door, and a wrought-iron gate all call for different methods, and we flag problems before drilling.

  3. 3

    Choose hardware that fits

    We go over grades, finishes, and key options with you. On a period home we help match the look of the existing hardware, and on a hillside gate we favor parts that tolerate dust and heat.

  4. 4

    Bore, fit, and align

    We mark and drill the door with proper templates, install the latch and bolt, and cut the strike mortise in the jamb so the bolt throws fully without binding or rubbing.

  5. 5

    Reinforce the strike area

    A deadbolt is only as strong as what it bolts into. Where appropriate we install a strike plate with longer screws that reach the framing behind the jamb.

  6. 6

    Test, key, and hand over

    We cycle the lock repeatedly with the door open and closed, confirm the keys work, and can key new locks alike so you carry one key for several doors.

What affects the price

  • Door material and condition: solid wood, steel, fiberglass, and hollow-core doors take different tools and time, and a damaged edge may need repair first.
  • Whether the door is already bored or needs fresh holes cut for a new lock.
  • Type and grade of hardware: a basic deadbolt, a heavier-duty grade, a handleset, or an electronic keypad vary widely in cost.
  • Number of locks and whether you want them keyed alike for a single key.
  • Reinforcement needs such as longer strike screws, a new strike plate, or jamb repair.
  • Gate or specialty applications, like hillside driveway gates, that need weather-tolerant or non-standard hardware.
  • Time of service, since we work around the clock and after-hours calls differ from scheduled visits.

Why Granada Hills chooses us

  • Fully mobile service: the work happens at your door with no storefront trip and no leaving the house unsecured.
  • In business since 1987, with owner David Shar leading the work rather than handing it to unknown subcontractors.
  • Available 24/7, useful when a new door is hung late or a break-in leaves an opening needing a lock right away.
  • Door-first approach: we assess the door and frame before drilling, rather than forcing a standard kit into a poor fit.
  • Sensitivity to period homes, helping choose hardware that suits mid-century entries instead of mismatched modern pieces.
  • Honest recommendations: if a cheaper hardware choice will do the job, we say so, and we tell you when a door needs repair first.

Lock Installation across Granada Hills

Granada Hills is mostly a Northern Valley community of 1950s and 60s ranch tract homes, and in ZIP code 91344 we often see doors that were remodeled over the decades. In Old Granada Hills near Chatsworth St, owners add a deadbolt to a side door, convert a garage entry, or fit a new front door and want a lock installed properly. Many original ranch doors only have a simple knob lock, so adding a quality deadbolt is a common upgrade.

Balboa Highlands, the Joseph Eichler tract, calls for care. Mid-century entries have a distinct look, and we help you choose hardware that respects it, whether that means adding a lock to a new atrium or side gate or matching finishes. Over in Knollwood and near Knollwood Country Club, larger homes often have several entries, patio doors, and side gates that benefit from locks keyed alike.

Up toward O'Melveny Park and the foothills around Bee Canyon, dust, heat, and Santa Ana winds are hard on exterior hardware and driveway gates. We lean toward weather-tolerant parts for those properties. With service reaching ZIP codes 91344 and 91394 along Balboa Blvd, Devonshire St, Zelzah Ave, and Rinaldi St, we come to wherever the door is, day or night.

Lock Installation in Granada Hills — FAQs

Can you install a lock on a brand-new door?
Yes. We drill the lock and latch holes, install the hardware, and set the strike in the frame. Call (323) 997-8867 and tell us whether the door is prebored or solid so we bring the right tools.
Can you add a deadbolt where I only have a knob?
Usually, yes. If the door is thick enough and in good condition, we can bore a new deadbolt hole above the knob and install the bolt and strike properly. We check the door edge before drilling.
Do you install locks on gates?
Yes, including side gates and driveway gates. Foothill properties near O'Melveny Park deal with dust and heat, so we recommend weather-tolerant hardware. Call (323) 997-8867 to describe the gate.
Can you key several new locks to one key?
Yes. We can key new exterior locks alike so one key works the front, back, and side doors. Just let us know how many locks you want installed.
Will new hardware suit my Eichler home in Balboa Highlands?
We can help you choose finishes and styles that fit a mid-century look instead of a mismatched modern piece. Tell us what the existing hardware looks like and we will talk through options.
Do you offer keypad or electronic lock installation?
We can install electronic and keypad deadbolts on suitable doors. We check door prep and the strength of the frame first, since a smart lock still needs a solid door to secure.
Is there a shop I can come to?
No. We are fully mobile and do all work at your home or property in Granada Hills. There is no storefront to visit.
Are you available at night or on weekends?
Yes, we are available 24/7. Call (323) 997-8867 anytime, and we will discuss your situation and next steps.
