Most El Monte businesses start out with a metal key and a deadbolt, and for a while that works. Then an employee leaves without returning a key, a landlord changes tenants, or a stockroom needs to be limited to two people. Access control solves those problems by letting you decide who can enter, and by letting you cancel one person's access without rekeying every door.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We install keypad locks, card readers and fob-based systems on business entrances, and we do it on-site. We are mobile only, so there is no showroom to visit. We come to your door, look at what it is made of, and recommend hardware that fits it.

El Monte has a lot of aluminum-storefront strip retail, older commercial buildings, and small offices tucked into converted residential-style structures. Each presents a different installation problem. A glass storefront door with a narrow stile, a hollow-metal back door, and a roll-up gate all call for different hardware, and we plan around that rather than forcing one product onto every entrance.

How it works in El Monte

  1. 1

    Talk through the entrance and your goals

    Call (323) 997-8867 and tell us about the door, how many people need access, and whether you want codes, cards, fobs or a mix. Because we are mobile and available around the clock, we can schedule around your business hours.

  2. 2

    On-site door and frame assessment

    We examine the door material, the stile width, the frame, the existing lock, and how the door closes. Aluminum storefront doors, wood doors and hollow-metal doors each limit which hardware will mount cleanly and securely.

  3. 3

    Choose the system type

    We explain the practical differences between a standalone keypad, a card or fob reader, and a system that manages many users. A small shop with a few employees often needs something simpler than a multi-door office.

  4. 4

    Install and secure the hardware

    We mount the lock or reader, set up the strike or electric release where needed, and check alignment so the door latches without forcing. We also look at whether the door can be pried or the latch bypassed, and address weak points we find.

  5. 5

    Program users and test

    We set up codes, cards or fobs, test each one, and confirm the door locks behind each use. We also check how it behaves if power is interrupted, so you know what happens in an outage.

  6. 6

    Walk through day-to-day use

    We show you how to add and remove users, change codes, and handle a lost credential, so you are not dependent on us for routine changes.

What affects the price

  • The type of system: a simple standalone keypad differs considerably from a card or fob reader tied to several users or doors.
  • Door and frame material, since aluminum storefront, wood and hollow-metal doors require different mounting and preparation.
  • Number of entrances and users, which affects how much hardware and programming is involved.
  • Whether the door needs an electric strike, magnetic lock or other release, and how power will be supplied.
  • Any repair or reinforcement the door or frame needs before new hardware will hold properly.
  • Whether you need after-hours or urgent installation, given that we are available 24/7.

Why El Monte chooses us

  • Fully mobile: we do the assessment and installation at your door, with no storefront to visit.
  • In business since 1987, with the owner, David Shar, leading the work.
  • Available 24/7, so installation can happen after closing rather than interrupting your customers.
  • We recommend hardware based on your actual door, not a single product pushed on every job.
  • We explain how to manage users yourself, so changing access does not require a service call.
  • We are a locksmith first, so we also address the physical weak points of the door, not just the electronics.

Access Control across El Monte

El Monte is a dense mix of commercial strips and residential neighborhoods, and access control needs vary across it. Along Valley Blvd and Garvey Ave, aluminum-storefront retail with roll-up security gates is common, and the narrow stiles on those glass doors limit which locks can be mounted. Around Downtown El Monte and the Valley Mall area, businesses often share buildings or back-of-house doors that benefit from controlled entry.

In Norwood and Mountain View, small offices, workshops and service businesses sit close to residential streets, and many of them want a simple way to give employees entry without handing out keys. We also work with property managers in the 91731, 91732, 91733, 91734 and 91735 ZIP codes who need a cleaner way to handle staff turnover or shared service doors.

Businesses near Santa Anita Ave, Ramona Blvd, Peck Rd and the I-10 and I-605 corridors often have deliveries and shift workers coming and going, which makes tracking keys difficult. Whether you are close to the El Monte Bus Station, the Metrolink station on Railroad St, or tucked away off a side street, call (323) 997-8867 and we will come to you.

Access Control in El Monte — FAQs

Can you install keypad or card access on an aluminum storefront door in El Monte?
Yes, in many cases. Storefront doors have narrow stiles, so we choose hardware designed to fit them. We check the door on-site first. Call (323) 997-8867 to describe yours.
What is the difference between keypad, card and fob systems?
A keypad uses a code, while cards and fobs are physical credentials presented to a reader. Cards and fobs make it easier to cancel one person's access, while keypads are simple and need nothing to carry.
Do you have a shop I can visit?
No. We are fully mobile and come to your business. There is no storefront, so call (323) 997-8867 and we will arrange a visit.
Can you install access control after business hours?
Yes. We are available 24/7, so installation can be scheduled after closing to avoid disrupting customers or staff.
What happens to the door if the power goes out?
It depends on the system and how the door is set up. We check and explain the behavior during installation, so you know how the door secures and how people exit.
Can I change codes or remove an employee myself?
Generally yes. We show you how to add and remove users and change codes before we leave, so routine changes do not need a service call.
Can you add access control to a door with a roll-up security gate?
The gate and the entry door are separate security points. We can discuss controlled access for the door, and we also repair gate locks that have seized or jammed.
How is the price determined?
It depends on the system type, door material, number of entrances and users, and any needed door repair. We explain the factors when you call (323) 997-8867.
