Installing a lock where none existed before is different from swapping an old one. A new door may arrive bored for a standard deadbolt, partly prepped, or not prepped at all. A side gate, a converted garage, a guesthouse, a pool-yard door or a freshly built storefront entry may have no hardware. Each of these needs the right lock for the door, the frame and the way the opening is used.

Glendora has a mix of building types that makes this work varied. Larger custom foothill homes in North Glendora often carry heavier doors and premium hardware. South Glendora is mostly post-war tract housing, where a new door or an added entry is a common project. Glendora Village has older buildings and small storefronts where doors, frames and fire or access needs differ from a typical house.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead tech David Shar. We are mobile only, with no storefront to visit. We come to your door, look at what you actually have, and install hardware that fits it properly, rather than forcing a generic kit into the wrong door.

How it works in Glendora

  1. 1

    Talk through the door and the goal

    Call (323) 997-8867 and tell us what the opening is: a new front door, a patio slider, a gate, a shop entry or an interior room. We ask about material, thickness, and whether you want keyed entry, a keypad, or a matched set with other locks on the property.

  2. 2

    Inspect the door and frame on site

    When we arrive we check the door material, thickness, edge, and the strike side of the frame. Solid wood, hollow-core, metal, and glass doors all need different handling, and a weak frame can undermine even a strong lock.

  3. 3

    Choose hardware that fits

    We go over options for the opening, such as a deadbolt with a handleset, a multipoint system for a tall patio door, or a commercial-style cylinder for a storefront. We explain tradeoffs in plain terms so you can pick what suits your use and budget.

  4. 4

    Prepare and install

    If the door is not bored, we cut the bore holes and latch mortise cleanly, then fit the lock and a properly aligned strike. We reinforce the strike area where it makes sense, so the bolt throws into solid material and not just thin trim.

  5. 5

    Test, key and hand over

    We cycle the lock repeatedly, check alignment with the door closed and open, and make sure keys work smoothly. If you want several locks keyed alike, we set that up so one key handles the whole property.

What affects the price

  • Whether the door is already bored and prepped or needs holes and a latch mortise cut for the first time
  • Door material and thickness, since solid wood, metal and glass each take different tooling and care
  • The grade and type of lock chosen, from a standard deadbolt to a multipoint or high-end designer set
  • Whether the frame or strike area needs reinforcement or repair before the lock can work properly
  • How many locks are being installed and whether they should be keyed alike
  • Access and timing, including after-hours calls or a property reached by a long private drive

Why Glendora chooses us

  • Fully mobile service, so installation happens at your door with the tools needed for drilling, mortising and fitting on site
  • Experience since 1987, including both modern doors and older doors that are out of square or have been refinished many times
  • Comfort with higher-end hardware such as Baldwin and Emtek sets and multipoint patio door systems common in foothill homes
  • Honest recommendations: we tell you if a lock is more than the door can support or if the frame is the real weak point
  • Available 24/7, so a new door or a freshly cut opening does not have to sit unsecured overnight

Lock Installation across Glendora

In North Glendora, foothill estates and mid-century hillside homes often sit behind gates or at the end of long private drives. New installs here can mean a multipoint lock on a large patio door, a matched handleset on a custom entry, or hardware for a guesthouse or workshop added to the property. Because we are mobile, we bring the tools to you, even if the route climbs off Glendora Ave or the foothills near Big Dalton Canyon.

Glendora Village has historic early-1900s buildings and boutique storefronts, where a new tenant may need locks on a back door, a storage room or a remodeled entry. Older frames can be uneven, so we fit hardware to what is actually there. South Glendora is largely post-war single-family tract homes, where new side doors, garage conversions and replacement doors are common reasons to install fresh locks. We serve ZIP codes 91740 and 91741, including areas near Citrus College, Lone Hill Ave and Grand Ave.

Whether you are off the Foothill Freeway (Interstate 210), along historic Route 66 on Alosta Ave or Foothill Blvd, or near the Glendora Country Club, call (323) 997-8867 any time of day or night. We will discuss the door and get a lock installed that fits it.

Lock Installation in Glendora — FAQs

What does lock installation cover that rekeying or replacement does not?
Installation is for doors with no lock yet, or new doors that need hardware fitted from scratch. That can include cutting the bore and latch holes, setting the strike, and mounting the lock. Rekeying only changes the pins in an existing lock. Call (323) 997-8867 if you are not sure which you need.
Can you install locks on a new door I bought myself?
Yes. Bring the door details when you call, such as material, thickness and whether it is pre-bored. We can fit locks to a door you supplied, and we will check that the hardware you chose matches the door and frame.
Do you install multipoint locks on patio doors in North Glendora?
Yes. Many larger foothill homes have tall patio or entry doors that suit multipoint hardware. We check the door and frame first, since these systems need a straight, well-supported door to work smoothly.
Can you put locks on a storefront in Glendora Village?
Yes. We install locks on storefront entries, back doors and storage rooms. Older downtown buildings can have unusual frames, so we inspect before recommending a cylinder and deadbolt or other hardware.
Can you key several new locks alike?
Yes. If you are installing locks on a front door, side door and garage entry, we can key them so one key works for all of them. Ask when you call (323) 997-8867 so we bring the right cylinders.
Do you come out at night or on weekends?
Yes. We are available 24/7 and fully mobile. If a new door or opening needs a lock to be secured tonight, call (323) 997-8867 and we will talk through what is needed.
Will installing a lock damage my door?
A new lock on a door that was never bored requires cutting holes, which is part of the work and is done cleanly. On doors that are already prepped, we aim for a fit that needs no extra cutting. We explain what is involved before we begin.
Do I need a stronger lock for a home near the foothills?
Not necessarily. The right lock depends on the door, the frame and how the entry is used. Gated or remote properties may justify higher-grade hardware, and we will give you an honest view of what is worthwhile.
