A smart lock sounds simple: swap the deadbolt, pair an app, and never carry a key again. In Pasadena the reality depends heavily on the door. A 1920s Craftsman in Bungalow Heaven, a mid-century courtyard apartment near Lake Avenue and an aluminum-frame storefront on Colorado Boulevard each need a different approach, and the lock that suits one can be a poor fit for another.

Crenshaw Lock Company has been working in Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are a mobile-only service with no storefront to visit. We bring the tools and hardware options to your door, check that the lock you chose will really work on your door, and then install and configure it so it behaves the way you expect.

Our work covers keypad deadbolts, Wi-Fi and Bluetooth smart locks, and keyless entry for residential and commercial doors. We also troubleshoot locks that were installed by someone else: units that will not pair, doors where the bolt drags, or keypads that stopped responding. If you are unsure which type of lock to buy, we can talk through the options before you spend money on one that will not fit.

How it works in Pasadena

  1. 1

    Talk through the door and your goals

    We start with a call about what you want: app control, a code for guests or tenants, a keypad only, or a lock that works with a system you already own. We ask about the door material, its age and whether it is an entry door, a patio door or a commercial glass door.

  2. 2

    Inspect the door, bore and latch

    On site we check the door thickness, the bore holes, the strike plate and how the door sits in its frame. Older Pasadena doors are often slightly out of square, and a smart lock's motor will struggle against a bolt that binds, so we fix alignment first where needed.

  3. 3

    Confirm the right hardware

    If you already bought a lock, we check that it fits. If not, we help you choose between keypad, Bluetooth and Wi-Fi models. On historic doors we discuss whether a retrofit is appropriate or whether the original hardware should stay in place.

  4. 4

    Install and test the mechanical lock

    We mount the lock, set the backset, and confirm that the bolt throws and retracts smoothly by hand and by motor before any electronics are set up. A smart lock that works poorly mechanically will also drain batteries faster.

  5. 5

    Set up codes, app and connectivity

    We pair the lock, create user codes, and connect it to your Wi-Fi or hub if it uses one. We test the signal at the door, since stucco, thick plaster and metal frames can affect range.

  6. 6

    Walk you through everything

    Before we leave, we show you how to add and remove codes, how to use the manual key override, what the low-battery warnings look like, and what to do if the app or Wi-Fi is down.

What affects the price

  • The type of lock chosen: a basic keypad deadbolt is a different job from a Wi-Fi smart lock with app integration or a commercial-grade unit.
  • Whether you supply the lock or we source it, since hardware is a large part of the total cost.
  • The condition of the door, including whether it needs boring, alignment work, a new strike plate or a reinforced latch area.
  • Door type, such as a wood Craftsman door, a hollow-core apartment door or an aluminum-frame glass storefront door that may need specialty hardware.
  • The number of doors and how much user and code setup is required, which matters for landlords and small businesses.
  • Time of day and urgency, since we are available 24/7 and after-hours or emergency calls are priced differently from scheduled visits.

Why Pasadena chooses us

  • Fully mobile service: we do the work at your door, so we see the actual door, frame and Wi-Fi conditions rather than guessing from a description.
  • Familiarity with older Pasadena housing, including Craftsman bungalows and American Foursquares where original mortise and rim hardware may be worth preserving.
  • We will tell you when a smart lock is not the best choice for a door, for example a historic front door where a rekey of the original lock is more appropriate.
  • Experience across both locksmith fundamentals and keyless electronics, so we can fix a sticking bolt as well as a pairing problem.
  • Business history in the region since 1987 under owner David Shar, who is directly involved in the work.
  • We also troubleshoot smart locks installed by others, rather than only selling and installing new ones.

Smart Lock Installation across Pasadena

Pasadena's housing stock shapes almost every smart lock decision we make. In Bungalow Heaven and other historic pockets, many homes still have original mortise locks, rim locks and brass escutcheons that add real character and, in protected districts, are part of what the neighborhood values. We often suggest keeping the original front door hardware and adding a keypad or smart deadbolt on a secondary door, or choosing a retrofit that does not require cutting into a period door. Madison Heights and Garfield Heights have larger, older homes where multiple entrances, side gates and service doors make keyless access especially convenient for family, cleaners and contractors.

Other parts of the city call for a different approach. Mid-century courtyard apartments near Caltech, PCC and Lake Avenue often use lighter doors where a landlord wants a deadbolt upgrade or keypad entry to avoid re-keying every time a tenant moves. In Old Pasadena and along Colorado Boulevard, shops with aluminum-frame glass doors need hardware designed for narrow stiles, so the lock choice matters before anything is ordered. In Hastings Ranch, newer doors usually accept standard smart deadbolts without much modification.

We serve ZIP codes including 91101, 91103, 91104, 91105, 91106 and 91107, and work with access from I-210, SR-134 and the Arroyo Seco Parkway. Whether you are near the Rose Bowl, the Norton Simon Museum or Huntington Hospital, call (323) 997-8867 any hour of the day.

Smart Lock Installation in Pasadena — FAQs

Can you install a smart lock on a historic Craftsman door in Bungalow Heaven?
Often yes, but we look at the door first. If the original mortise or rim lock is worth keeping, we may recommend rekeying it and adding a smart lock elsewhere. Call (323) 997-8867 to discuss your door.
Do you install smart locks at night or on weekends?
Yes. Crenshaw Lock Company is available 24/7 and fully mobile. Call (323) 997-8867 and we will talk through the job and when we can come.
Will a smart lock work on my aluminum storefront door?
Sometimes. Narrow-stile glass doors on Colorado Boulevard and Lake Avenue need hardware made for that frame, so we check the door before choosing a lock. Call (323) 997-8867 if you are unsure.
I bought a smart lock online. Can you install it?
Yes, in most cases. We check that it fits your door's thickness and bore, then install and set it up. If it does not suit your door, we will say so honestly.
Can a landlord use keypad locks for apartment units?
Yes. Many landlords near Caltech and PCC use keypad or smart deadbolts so codes can be changed between tenants without new keys. We can set up codes and explain how to manage them.
What happens if the battery dies or the Wi-Fi goes down?
Most smart locks have a backup such as a physical key, a keypad that works without Wi-Fi, or an external power contact. We show you your lock's override during setup.
Can you fix a smart lock that stopped working?
Usually we can diagnose it. Common causes include a misaligned bolt, weak batteries, pairing issues or a failed motor. Call (323) 997-8867 and describe what is happening.
How is the price of smart lock installation determined?
It depends on the lock type, who supplies it, the door's condition, how many doors there are and the time of the call. We explain the factors before the work begins.
