What does access control installation mean for a Cerritos business?
Access control replaces the metal key with something you can manage: a code, a card, a fob, or a credential on a phone. Each door gets a reader or keypad, a controller that decides who is allowed in, and an electric lock that releases when the answer is yes. The lock is usually an electric strike or a magnetic lock, and the choice depends on the door.
The reason most business owners call us is the same everywhere. Keys get copied, lost, or kept by people who have left. Rekeying fixes that once, but it does not stop it from happening again. With a business access control system you cancel one credential and everyone else keeps working. You can also see which credential opened which door, and set which doors open for which people and at what hours.
We do this work for offices, warehouses, retail back doors, clinics, and shared suites in Cerritos. We do not push a system on a door that does not need one. Some doors are better served by a good commercial lock and a master key plan, and we will say so. If that is closer to what you need, our commercial locksmith service in Cerritos covers it.
Which access control system fits your doors?
There is no single best setup. The right choice comes from how many doors you have, how many people use them, how often staff change, and how much record-keeping you want. These are the main options we install:
- Keypad access control: a code entered at the door. It is the simplest keyless entry for business use and works well for a back door or a small team. The drawback is that codes get shared, so it fits best where you rarely need to know who came in.
- Card access system or key card entry system: each person gets a card, and you can cancel one without touching the others. This suits offices and suites with regular staff turnover.
- Key fob access control: the same idea in a form that lives on a key ring. Fobs hold up well in warehouse and shop environments where cards get bent or dirty.
- Credential-based entry on a phone: a reader that accepts a credential from a phone. It suits teams that already carry their phones everywhere, and it can be combined with cards for people who do not.
- Combination readers: a reader that takes a card plus a code, for the door that guards inventory, records, or a server closet.

Call (213) 577-1366Electric strike or magnetic lock: how do you choose?
An electric strike replaces the strike plate in the door frame. It works with the lock already in the door, releasing the latch when the reader approves a credential. For most wood, hollow-metal, and many aluminum doors, an electric strike installation is the cleaner option. The door still latches mechanically, and it keeps working as a normal door when the strike is not powered, depending on how it is set.
A magnetic lock installation uses a large electromagnet on the frame and a plate on the door. It holds when powered and lets go when power is cut. Maglocks suit glass doors and doors where a latch cannot easily be added. They also bring more rules, because the door has to release for anyone leaving, and fire and life-safety requirements apply. Egress release and how the lock behaves in a power cut are decisions to make before the first hole is drilled, not afterward.
The type of door decides a lot. Where an exit device is involved, hardware like a panic bar has to work together with the access control rather than fight it. Cerritos has hot summer afternoons inland, and a sun-exposed door can expand slightly. That matters for both options, because a strike or maglock that is aligned perfectly in the morning can bind later in the day if the door is not square. We check alignment with that in mind.
How do we install a business access control system?
Here is the process we follow, whether it is one door or several.
- Walk the doors. We look at each opening: door material, frame, existing lock, how people actually use it, and where power and cabling could run.
- Talk through who needs access. You tell us who comes and goes, when, and which doors matter most. We turn that into a simple plan for credentials and schedules.
- Recommend a setup. We propose the reader type, strike or maglock, and controller for each door, and explain why. If a door is better left with a conventional lock, we say so.
- Prepare the door and frame. That can mean cutting the frame for a strike, mounting a maglock, or checking that hinges, closer, and latch are in good shape. A weak door will undermine good electronics.
- Mount and wire the hardware. Readers, locks, power supplies, and release devices go in. Where a job needs new power or substantial new cabling, other trades may be involved, and we will tell you before work starts.
- Program the system. We load credentials, set schedules, and test every door with the power on and with the power off, plus the exit side.
- Walk you through it. You or your office manager learn how to add and remove credentials, and we leave you with clear notes on how each door behaves.

Call (213) 577-1366How do multi-door and employee access control work day to day?
On a multi-door access control system, each person is set up once and then given access to specific doors. The front door might open during business hours for everyone. The stockroom opens for two people. The office with the files opens for the owner and a bookkeeper. When someone leaves, you delete one entry instead of re-keying every door.
Employee access control also fixes the small daily friction. New hires get a credential on day one rather than waiting for a set of keys to be cut. A temporary worker can get a credential that works only on certain days. Lost cards stop working the moment you cancel them, instead of becoming a quiet security gap for months.
If your building already uses a key hierarchy and you want to keep some of it, a master key system can sit alongside electronic doors, so you are not forced into replacing everything at once. Many Cerritos businesses start with the one or two doors that cause the most worry, then add doors over time. We design the first stage so it can grow without starting over.
How much does access control installation cost in Cerritos?
We do not quote prices in a web page, because the honest answer depends on the doors in front of us. What moves the cost, roughly in order of impact:
- Number of doors. Each opening needs its own reader and lock, and the controller and power supply scale with the count.
- Type of door and frame. A solid hollow-metal door with a good frame is quicker to prepare than a thin or warped door that needs repair first.
- Strike or maglock. The hardware differs, and a maglock often needs extra release devices for safe exit.
- Reader and credential type. A basic keypad is lighter than a system with cards, fobs, phone credentials, and combination readers.
- Wiring and power. A short run to a nearby ceiling is simpler than a long run through finished walls or across a warehouse.
- Software and reporting. Do you need an audit trail and scheduling, or only a code that opens the door?
- Existing hardware. Reusing a good lock or closer can reduce the work. Replacing worn parts adds to it.
What about access control repair and upgrades?
Not every call is a new install. Access control repair is a big part of what we do: a reader that no longer responds, a strike that buzzes but does not release, a maglock that does not hold, or a door that works for some cards but not others. Often the electronics are fine and the problem is mechanical. A door that has sagged, a closer that slams, or a latch that no longer lines up with a strike can mimic an electronic fault. A worn door closer is a common culprit, and we check it before replacing any reader.
An access control upgrade is a different job. It might mean moving from a shared keypad code to individual cards, adding doors to an existing system, or replacing old readers that can no longer be supported. We can usually tell you whether an existing system is worth keeping. If it works and can grow, building on it is usually the more economical route. If parts are no longer available or the controller is a dead end, we say so plainly.
If you are locked out of a business because an electronic door failed, our business lockout service is the quickest path to getting inside, and we can then look at why the door failed.

Call (213) 577-1366Access control around Cerritos: Industrial Park, Towne Center, and beyond
Cerritos is an inland city in southeast Los Angeles County, ZIP 90703, and the business areas differ a lot from one another. In the Cerritos Industrial Park, the typical need is warehouse and office doors: a rear dock door, a shared entry for staff, an office that has to stay locked even when the warehouse is busy. Fobs and keypads tend to suit those settings, and a multi-door system lets a manager open the office without handing out a warehouse key.
Around Cerritos Towne Center and the Los Cerritos Center area, the picture is retail and service businesses. The front door is the customer's, but the back-of-house doors, stockrooms, and offices are where access control earns its place. Along the Carmenita Road and South Street corridors and near the Civic Center area, smaller offices and professional suites often want one or two controlled doors rather than a full system. In the Cerritos Auto Square district, dealership-type buildings often have a mix of public and private doors, and we plan around that mix.
Because Cerritos is inland, summer afternoons run warmer than in coastal cities, so sun-exposed doors can swell a little and alter how a strike or maglock lines up. Salt corrosion is not a meaningful factor here, which is good news for outdoor readers and hardware.
For the Shadow Park gated community, which has a staffed gate, entry hardware is a different kind of job, and our gate lock repair page is the place to start. Our base is in Westwood, about 29 miles away, and we also run mobile vans, so we come to your site for the survey and the install.
Why call Wilshire Lock & Key for access control?
We have been in business since 1987. That means we have worked on the door types you actually have, including old ones, and we know when a door needs repair before it can take electronics. We have a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans. You deal with one company from the first phone call to the finished install, with no dispatch middlemen passing your job around. David, the owner and lead technician, oversees the work.
California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for that license number before work begins. That applies to us as well, and it is a fair question for anyone you hire.
We also keep to our own lane. This page is about electronic entry. If you need related work, such as commercial door hardware or a connected lock for a home or small office, we can do it, and our smart lock installation page covers the lighter-weight options. Call (213) 577-1366 any time of day. We answer 24 hours a day, 7 days a week.
Frequently asked questions
What is the difference between keypad access control and a card access system?
A keypad uses a code that anyone can learn and share. A card access system gives each person their own credential, so you can cancel one without affecting anyone else, and many systems can record which card opened which door. Keypads suit small teams or low-risk doors. Cards or fobs suit businesses with staff turnover.
Do I need an electric strike or a magnetic lock?
It depends on the door. An electric strike works with a latch in a standard door and frame and is usually the cleaner choice. A magnetic lock suits glass doors and openings where adding a latch is hard, but it comes with stricter exit and life-safety requirements. We look at the door and tell you which fits.
Can you add access control to doors I already have?
Often yes. Many existing doors can take a strike or maglock after we check the door, frame, hinges, and closer. If a door is badly worn or warped, it may need repair first. We assess each opening during the survey and will tell you honestly if a door is not a good candidate.
Can I control multiple doors and different employees?
Yes. A multi-door access control system lets you decide which people can use which doors, and at what times. Staff can have access to the front and a stockroom while only a manager can open the office. When someone leaves, you cancel their credential rather than re-keying every lock.
Can you repair an access control system someone else installed?
In many cases, yes. We start by finding out whether the fault is electronic or mechanical, since a misaligned strike or a sagging door often looks like a failed reader. Whether the older system is worth keeping depends on whether parts and support still exist, and we will tell you plainly.
Will the doors still open if the power goes out?
That is set during planning, and it differs by door. A strike can be configured to stay locked or unlocked without power, and a maglock releases when power is lost. Exit routes must always work for anyone leaving. We test each door with power on and off before we finish.
How much will access control installation cost?
We cannot give a fair number without seeing the doors. Cost depends on how many doors, the door and frame condition, strike or maglock, the reader and credential type, the wiring and power needed, and whether you want reporting and scheduling. Call (213) 577-1366 and we will explain what applies to your site.
Do you serve all of Cerritos, and can I call after hours?
Yes. We serve Cerritos, including the Industrial Park, Towne Center, the Los Cerritos Center area, and the Civic Center area. Our phone line is answered 24 hours a day, 7 days a week at (213) 577-1366. Our base is in Westwood and our mobile vans come to you.
