A smart lock is only as good as the door it is mounted on. In Covina that matters, because the housing stock varies so much. A 1920s Craftsman or Spanish bungalow near Citrus Ave may still have an original mortise lock or an old rim lock, while a post-war tract home may have a standard bored deadbolt that accepts most modern hardware. We look at the door first, then recommend a lock that fits it, rather than forcing a device onto a door that was never meant for it.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, under owner and lead technician David Shar. We are mobile only, so there is no storefront to visit. We bring the tools and a range of keypad, keyless and app-connected options to your door, handle the installation, and walk you through setup so you are comfortable using it before we leave.

We also fix what others leave behind. If you already own a smart lock that will not pair, drops its connection, eats batteries, or does not line up with the strike plate, we can troubleshoot it. Whether you are in a downtown apartment, a Charter Oak ranch home or a larger-lot house in Covina Hills, the goal is the same: a lock that works every day and still has a reliable way in if the electronics fail.

How it works in Covina

  1. 1

    Talk through your needs

    Call (323) 997-8867 and tell us about the door, who needs access, and whether you want a keypad, a fingerprint reader, or an app-connected lock. We will explain what is realistic for your situation.

  2. 2

    Inspect the door and hardware

    We check door thickness, the bore holes, the edge preparation, the strike plate and the frame. On older Covina homes we look for mortise locks or worn rim hardware that may need adapting or replacing.

  3. 3

    Recommend a fitting lock

    We suggest options that suit your door and your habits, including how the lock is powered, how it connects, and whether it keeps a physical key override.

  4. 4

    Install and align

    We mount the lock, correct alignment problems, and make sure the bolt throws smoothly. A smart lock that binds will drain batteries and fail early, so this step gets real attention.

  5. 5

    Set up codes and connectivity

    We program user codes, pair the lock with your phone or home system if you want that, and test every function with you at the door.

  6. 6

    Final test and handoff

    We show you how to change codes, replace batteries and use the manual override, so you are not guessing later.

What affects the price

  • The type of lock chosen: a basic keypad deadbolt differs from a fingerprint, app-connected or multi-function model.
  • The condition and type of the door, including whether it needs drilling, boring or adjustment to accept the new hardware.
  • Older mortise or rim hardware on historic homes, which can require adapters or a different approach than a standard deadbolt.
  • How many doors you want converted, and whether they can share a matching setup.
  • Whether this is a new installation or troubleshooting and reconfiguring a lock you already own.
  • Time of day and the location of the job, since we are available 24/7 and travel to you.

Why Covina chooses us

  • Fully mobile service: we come to your Covina door with tools and options in hand, with no storefront trip.
  • In business since 1987, so we have worked on both vintage hardware and current electronic locks.
  • We check the door before selling the lock, which avoids installing a device that will not hold up.
  • We favor locks that keep a physical key backup, so a dead battery never leaves you locked out.
  • We teach you the lock at your door, including codes, batteries and override, before we leave.
  • Available 24/7, including when a smart lock failure leaves you stuck outside.

Smart Lock Installation across Covina

Covina's older core is a good example of why smart lock installation needs care. Around historic Downtown Covina and Citrus Ave, many Craftsman and Spanish bungalows date to the 1920s and 30s, and their doors may carry original mortise locks. Retrofitting one of these can mean a new deadbolt, an adapter, or a different style of keyless entry. Small downtown retail near Heritage Plaza and the Covina Center for the Performing Arts also benefits from keypad locks, since staff access can be changed without rekeying every time someone leaves.

East of downtown, Charter Oak (91724) is largely post-war ranch and tract housing, where standard door preparation often makes installation simple. Homeowners there frequently add a smart lock after buying a house, so that former owners' keys stop mattering. Further south, Covina Hills has larger-lot homes with more doors, side gates and entries, where matching locks across several doors can be convenient. We serve Covina ZIP codes 91722, 91723 and 91724.

If you commute from the Covina Metrolink station on the San Bernardino Line, or drive Interstate 10, Azusa Ave, Grand Ave, Badillo St, San Bernardino Rd or Arrow Hwy, a keypad or app-controlled lock means no hunting for keys after a long day. Call (323) 997-8867 any hour and we will come to you.

Smart Lock Installation in Covina — FAQs

Can you install a smart lock on an older Covina bungalow?
Often yes, but it depends on the door. Homes near Citrus Ave may have mortise or older rim locks, so we inspect first and tell you what will work. Call (323) 997-8867 to describe your door.
Do smart locks still use a key?
Many do, and we generally recommend models with a physical key override as a backup. Some are fully keyless, and we will explain the tradeoffs for your door.
Can you fix a smart lock I already bought?
Yes. We troubleshoot pairing problems, battery drain, misaligned bolts and code issues. Call (323) 997-8867 and tell us the brand and what it is doing.
Will a smart lock fit my door?
Most standard doors accept one, but the bore holes, door thickness and edge preparation matter. We check these before installing so the lock operates smoothly.
I just bought a house in Charter Oak. Should I install a smart lock?
It is a popular choice, since you can set new codes and stop relying on keys that previous owners or contractors may hold. We can also rekey other doors at the same visit.
What happens if the batteries die?
Most smart locks warn you before batteries run out, and many have a backup key or external power option. We show you how yours works during setup.
Can I give temporary codes to guests or workers?
On models that support multiple user codes, yes. We set them up and show you how to add or remove them yourself.
Are you available at night or on weekends?
Yes, we are available 24/7 and fully mobile. Call (323) 997-8867 any time to schedule installation or get help with a malfunctioning lock.
