What does access control installation involve for a Diamond Bar business?
Access control replaces or supplements a metal key with something you can manage: a code, a card, a key fob, or a phone credential. The door still has to latch, close, and stay secure, so the work is part electronics and part door hardware. A reader or keypad decides who is allowed in. A strike or magnetic lock is the piece that actually releases the door. A power supply and wiring tie it together.
That is why this is a locksmith job and not just an electronics job. A system can be perfectly programmed and still fail if the door sags, the frame is out of square, or the closer slams the door before the strike can seat. We have been working on doors in Southern California since 1987, and most access control problems we see trace back to the door, not the software.
When we install keypad access control, a card access system, or a multi-door setup, we treat the opening as a whole: the door leaf, the frame, the hinges, the closer, the egress hardware, the wiring path, and the credential list. If one of those is wrong, we tell you before we drill anything.
When does a business outgrow keys?
Most businesses do not wake up and decide to install electronic access control. They get pushed there by a specific problem. A former employee never returned a key. Nobody can say how many copies of the back-door key exist. A manager is tired of rekeying every time someone leaves. Or the business grows to a second suite or a second door and keeping track of who holds what becomes a part-time job.
Credential-based entry fixes the core weakness of keys: a key cannot be switched off. A lost card or a departed employee's fob can be removed from the system in minutes by whoever administers it, and the door itself stays the same. You also get the option of schedules, so a cleaning crew's credential works in the evening and not on weekends.
Access control is not always the right answer, though. A single-door shop with two keyholders and no turnover is often better served by good commercial cylinders and a tidy key log. If that describes you, we will say so, and point you toward our commercial locksmith service instead of selling you a system you will not use.
Which type of access control fits which door?
There is no single best system. The right pairing depends on the door, how many people use it, and what happens when the power goes out. These are the building blocks we work with.
- Keypad access control: a code entered at the door. Simple, no cards to lose, and a good fit for a back door or storeroom with a small group of users. The weakness is that codes get shared, so we recommend individual codes where the system supports them.
- Card access system or key card entry system: each person carries a card. Easy to add and remove people, and it gives you a record of who used which door when the controller supports logging.
- Key fob access control: the same idea in a form that lives on a key ring. Employees tend to keep fobs with them, which cuts down on lost cards.
- Electric strike installation: the strike replaces the standard strike plate in the frame and releases the latch electrically. It keeps your existing lockset and is a good choice for most single doors with a solid frame.
- Magnetic lock installation: an electromagnet holds the door shut against a plate. It is common on glass and aluminum doors where a strike will not fit, but it needs correct release devices so people can always leave.
- Multi-door access control: one controller managing several openings so you set permissions in one place. This is what makes employee access control practical once you have more than two or three doors.

Every job is different, but the sequence is consistent. We would rather spend time on the walkthrough than fix a bad assumption after the wires are pulled.
- Walk the doors with you. We look at the door material, frame, hinges, closer, existing lock, and the route a wire could take. We also ask who needs to get in, when, and what you want to happen when someone loses a credential.
- Decide the failure mode. A door can fail secure, staying locked when power is lost, or fail safe, releasing when power is lost. Interior offices, stairwell doors, and exterior doors do not all want the same answer, and the choice affects which hardware we use.
- Check the egress. People inside must be able to leave without a key, a code, or special knowledge. We plan the exit path first, and if the door needs panic bar installation or other egress hardware, that goes into the plan.
- Prepare the door and frame. Where needed we align the door, adjust the closer, or reinforce the frame so the strike or magnet works reliably. Related hardware questions are covered under commercial door hardware.
- Mount and wire the hardware. Readers, keypads, strikes, or maglocks go in, along with the power supply and controller. We label the wiring so the next technician, whoever it is, can follow it.
- Enroll the credentials. We set up cards, fobs, or codes with you, and show whoever will administer the system how to add and remove users.
- Test under real conditions. We cycle each door repeatedly, test the exit path, and test what happens when power is removed. Then we walk you through everything before we leave.
What affects the cost of access control installation?
We do not quote numbers on a web page because two doors that look alike can be very different jobs. What we can do is tell you what moves the cost up or down, so the quote you get makes sense.
The biggest factor is the number of openings. Each door needs its own reader or keypad and its own releasing hardware, and the controller and power supply are sized to the total. After that, the type of door matters. A solid wood or hollow metal door with a good frame is usually the more economical route for an electric strike. A frameless glass door or a thin aluminum storefront frame can need different hardware and more labor.
Wiring is the other large variable. A door next to the controller closet is a short run. A door across the suite, behind finished walls or a drop ceiling, takes more time. Existing conduit helps; no conduit does not stop the job but it changes the plan.
Other things that affect cost:
- The credential type you choose: codes, cards, fobs, or phone-based credentials
- Whether you want audit logs, schedules, and remote administration or just basic entry
- Whether the existing lockset, closer, and frame can be reused or need replacing
- Egress hardware required for safe exit
- Whether we are installing new, upgrading an old system, or repairing one that partly works
- Working hours, if the job has to happen after the business closes

Call (213) 577-1366Why call Wilshire Lock & Key for access control?
We have been in business since 1987, with a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans that cover Diamond Bar and 139 other cities across Los Angeles and Ventura counties. That matters for access control because the job is rarely finished in one visit and you want a company that is still around when you need a code reset or a repair.
You deal with one company, not a dispatch service that hands your job to whoever is free. David, the owner and lead technician, oversees the work. When you call (213) 577-1366, the line is answered 24 hours a day, seven days a week, so a door that will not lock at night does not have to wait until morning.
One thing to check with any locksmith, including us: California requires locksmith companies to hold a BSIS LCO license, and you should ask to see the number before work begins. Our license number is being added to this site, but the question is a fair one for any company you hire. You can also use our contact page to describe your doors before we visit.
Access control in Diamond Bar: what the local buildings call for
Diamond Bar was master-planned from the 1960s onward, and that shows in how businesses are laid out. Retail and office space clusters along the Diamond Bar Boulevard, Grand Avenue, Golden Springs Drive, and Brea Canyon corridors, often in shopping centers with multiple tenants sharing a building. In ZIP 91765, that tends to mean glass storefront doors at the front and steel service doors at the back, and the two need different hardware.
A typical local scenario is a tenant in one of the Diamond Bar Boulevard or Grand Avenue shopping centers who wants keyless entry for business use on a back door or stockroom. The front glass door might be a good candidate for magnetic lock installation or a strike-compatible hardware swap, while the rear steel door is an easy electric strike installation. If a front door is already giving trouble, our storefront lock repair work often comes first, because a door that does not close properly will defeat any reader.
Climate matters too. Diamond Bar has hot summers and wind funneling through Brea and Tonner Canyons. Heat can make doors expand and bind against the frame, which stresses a strike or keeps a maglock plate from meeting the magnet cleanly. Dust collects in exterior keyways and around outdoor keypads. We choose exterior-rated readers where weather is a factor and set door clearances with summer expansion in mind.
Some properties need gates as well as doors. The guard-gated Country Estates is home to large custom homes on estate lots, and any commercial or home-office property that ties a gate to an entry system should be planned as a package. For the gate side, see gate lock repair. Homeowners in Diamond Point or the South Pointe area who want keypad entry for a house, rather than a business, should look at smart lock installation instead.

Call (213) 577-1366Can you repair or upgrade an access control system we already have?
Yes. Access control repair is a large part of this work, and many Diamond Bar businesses already have a system that was installed years ago by someone no longer around. Common problems include a reader that works only sometimes, a strike that buzzes but does not release, a maglock that does not hold, a controller nobody has the login for, or a power supply that has quietly failed.
We start by finding out whether the problem is the credential, the reader, the controller, the power, the wiring, or the door. A door that has dropped slightly on its hinges can look like an electronics fault. Fixing the hinge may be all that is needed.
An access control upgrade makes sense when the system cannot be supported anymore, when you need more doors than the controller can handle, or when you want to move from shared codes to individual credentials. Sometimes we can keep the wiring and replace only the readers and controller. Sometimes we recommend a clean start. If you are also thinking about how keys and credentials relate across the building, a master key system can run alongside electronic doors for the areas that stay mechanical.
Frequently asked questions
What is the difference between a keypad system and a card or fob system?
A keypad uses a code, so there is nothing to carry or lose, but codes can be shared. A card or key fob system gives each person their own credential, which you can cancel individually. For a small team on one door, a keypad can be enough. For more people or more doors, cards or fobs are usually easier to manage.
Should my business door use an electric strike or a magnetic lock?
An electric strike works with your existing latch and is common on solid doors with sturdy frames. A magnetic lock is often used on glass or aluminum doors where a strike will not fit. The choice also depends on whether the door should fail safe or fail secure when power is lost. We decide that at the walkthrough.
What happens to the doors if the power goes out?
It depends on how each door is set up. A fail-secure door stays locked but can be opened from the inside by the exit hardware. A fail-safe door releases when power is lost. Many systems also have battery backup. We plan this door by door because an exterior door and an interior office door rarely want the same behavior.
Can you add access control to my existing doors?
Usually, yes. Many doors can take a reader and an electric strike with minimal changes. Problems come from warped frames, thin glass doors, or doors that do not close fully. We inspect the door first and tell you if hardware needs to be corrected or replaced before the electronics go in.
How do I remove a former employee's access?
With a card, fob, or individual code system, whoever administers the system deletes that person's credential, and it stops working at every door. This is one of the main reasons businesses move away from keys. We set up the system and show you how to do it yourself. If you want help, you can call us.
Do you install access control for multiple doors?
Yes. Multi-door access control uses a controller that manages several openings, so you set permissions in one place. We plan the number of doors, the cable runs, and the power supply together. Adding a door later is simpler if the controller was sized with some room for growth.
Can you fix an access control system someone else installed?
In most cases, yes. We figure out whether the fault is in the credential, reader, controller, power supply, wiring, or the door itself. Some older systems are difficult to support if parts are no longer made or nobody has the programming login. If that is the case, we explain the options for an upgrade.
Is it okay to call after hours about a door that won't secure?
Yes. Our line at (213) 577-1366 is answered 24 hours a day, seven days a week. If your access-controlled door will not lock or will not open, tell us what it is doing and what type of door it is, and we will work out how to secure the building and plan the repair.
