La Puente, Los Angeles County
Magnetic Lock Installation in La Puente
Short answer: A maglock has no latch, so exit rules drive the design. For people to leave without special knowledge, an exit-side motion sensor, a push button and a fire alarm release normally cut power to the lock, and a power failure frees the door. Your fire marshal or building department has the final say, and we design around it.

Many maglock calls start after something goes wrong: an inspector flags a door, a tenant says the exit button doesn't work, or a staff member finds a door that won't release. Magnetic lock installation in La Puente should begin with the exit, not the lock. We identify how people leave, which devices release the door, what happens when the fire alarm sounds or the power fails, and whether your building department will want to see it. Then we choose the magnet, mount it, wire it and test it. If a lock someone else installed isn't right, we'll tell you what has to change.
How this works in La Puente
Doors dictate the hardware. An outswing steel door with a solid header takes a standard header-mount lock easily. An inswing door usually needs a bracket kit so the magnet and plate meet squarely. Aluminum storefronts have narrow headers and thin extrusions, so the magnet may need a through-bolted backing plate or may be better as a concealed shear lock. Tempered glass can't be drilled once it has been made, so glass doors use clamp-style brackets that grip the glass without any holes. Double doors need either two magnets or a combined unit, plus a plan for the inactive leaf. Wood doors need through-bolts long enough to resist pulling out. We look at the door, the header and the swing during the survey and choose the mounting kit before you see a price, because it is often the largest piece of magnetic lock installation. If the header cannot carry a magnet, we say so and suggest another route.
Work included on a typical visit
- Header-mounted maglocks on outswing doors. The standard configuration puts the magnet on the secure side of the header and the plate on the matching spot of the door. Through-bolts give the plate a firm grip. We set the plate loose enough to float and seat itself, then tighten the fasteners so nothing walks loose with slamming.
- Frameless and tempered glass doors. Tempered glass can't be drilled or cut after it is made, so glass-door maglocks use clamp brackets that grip the glass edge without holes. We pad the clamps, tighten them evenly, and mount the magnet on a header or bracket that can carry the load. Nobody should drill your glass.
- Exit sensors and push buttons. Sensors can be fooled by drafts, signs and sunlight, and buttons can be placed where nobody notices them. We review the door's surroundings, aim and set the sensor, mount the button at a reachable height with a visible label, and test both from the exit side, where it matters.
- Fire alarm release and code review. A fire alarm release uses a relay from the panel to cut lock power when the alarm activates. We install the relay on the lock's power line and test it with your fire alarm contractor, who has to trigger the panel. When building rules require sprinkler release too, we plan for that.
- Power supplies, battery backup and surge protection. Battery backup keeps a maglock holding through short outages and brownouts, though the batteries wear out and the door will release once they are exhausted. We size the battery to your preferences, explain the limits, and put a replacement date on the enclosure so the backup is not forgotten.
How La Puente shapes the job
Shopping-center tenants use maglocks mostly on stockroom, back-of-house and office doors, and sometimes on glass entry doors after hours. The storefront frame belongs to the landlord, and exit rules apply to the rear corridor too. In La Puente centers we check delivery routes, fire alarm tie-ins and the way back doors are really used, because a maglock that traps an employee carrying inventory is a problem waiting to happen.
Inland heat stresses power supplies, batteries and plastic parts. A supply in an unvented ceiling can run hot and fail, and backup batteries age faster. Glass and aluminum doors expand in afternoon sun, which can shift plate alignment slightly through the day. We mount supplies where air moves, check alignment hot as well as cool, and put a battery replacement date on the label.
Apartment complexes use maglocks on glass-door fitness rooms, leasing offices, package rooms and clubhouses. Residents' expectations are simple: the door opens when they badge, and it opens from inside. Management needs logs, easy credential changes and a way to find a door left ajar. We install door-position switches and clear exit buttons, and we ask early where the fire marshal wants alarm integration.
Situations this covers
- A typical call: a small company keeps its network equipment in a closet with a hollow-metal door and a keyed knob that everyone has copied. The manager wants a keypad. We'd mount an inswing bracket kit, run cable above the ceiling, set a short release time, and discuss whether a strike on the existing latch might be a better fit.
- Picture a records room in a clinic. Only certain staff should enter, and the door is rarely used but must be monitored. We'd install a maglock with a bond sensor and a door-position switch, a reader outside and an exit sensor inside, plus an entry log, so the office manager can tell when the door was opened and whether it was left unsecured.
- A coworking space in a converted storefront wants evening card access on its double entry doors, while the landlord insists on no visible damage. We'd choose surface magnets with brackets mounted to existing holes where possible, hide cable behind trim, keep the work reversible, and give the landlord a simple drawing of what changed so the lease terms stay intact.
- Say an earlier installer put a maglock on an office door with a card reader and nothing else. There is no exit button, no sensor and no link to the fire alarm. We'd survey the door, explain what is missing, add a sensor, a push button and a release relay, and tell you honestly which parts the building official will care about.
How the visit works
- Survey the door, header and exit path. Before choosing a magnet, we check what you're attaching it to. A header that flexes, a door that sags or a closer that slams will undermine any lock. We note the problems and, if necessary, fix them before the lock goes in.
- Design the release path and quote. A good design starts with the exit. We list every way the door releases, then add the credential that lets people in. You see the quote door by door, with notes on what could change. Nothing is drilled until you have approved it.
- Mount the magnet and armature plate. We mark the layout, drill and anchor the bracket or backing plate into solid material, and mount the magnet square to the door. The plate goes on the door with through-bolts and a flexible bushing so it can seat flat against the magnet face, and we tighten everything to specification.
- Run the power, sensors and fire alarm release. Low-voltage cable runs from the lock to the power supply, sensors, button and controller. We route it through the ceiling or a raceway, keep power and signal wires neatly separated, and label both ends. Fire alarm relays go in the lock's power line and are tested with the alarm contractor.
- Program credentials and set the timers. Programming depends on the controller. A standalone keypad takes a few settings; a networked system takes a user list and schedules. We create the first credentials with you, show you how to add and delete them, and leave the settings recorded.
- Test every release and hand over. We walk through the door as a stranger would, looking for anything confusing. Then we show your staff the button and the sensor, give you the wiring record and tell you who to call about the alarm panel.
What affects the cost
- Holding force and number of leaves. Each additional leaf or door adds a lock, a plate, brackets and wiring. Several doors in one visit share survey time and programming, which lowers the cost per door, but we still quote each opening separately so you can approve some doors now and others later.
- Power supply, backup and controller. Maglocks draw power continuously, so the supply is a real component. A fused, regulated supply costs more than a plug-in adapter and does the job properly. Battery backup, a controller and readers add more. We build the list so you can add or skip items.
- Cable route and header access. Headers can hide surprises: steel, conduit, glazing channels or nothing solid to anchor into. We probe before committing, and our quote notes what we found and what might change once the frame is open. A header that turns out to be thin drywall or hollow aluminum means backing plates or a different mounting plan, and we would rather tell you that before drilling than after.

What not to do
- Using a maglock where the door must stay latched. Fire-rated doors, some stairwells and other openings need hardware that latches positively, which a maglock does not do. Ask your building department before you specify one. If you are not sure how your door is classified, look for a label on the edge of the door or frame.
- Drilling tempered glass. Once glass is tempered it can't be drilled or cut, and any attempt can shatter the panel. Use glass-door clamps that grip the edge. If a door was drilled previously, we can judge whether existing holes can be used safely.
- Wiring the exit button through the controller only. If the controller hangs or loses power to its logic, the button does nothing. The push button should interrupt lock power directly, so the door opens even if the access system is dead.
Advice before you book
- Aim the exit sensor with care. It should see people approaching from inside, not passers-by outside or sunlight on a glass door. Seal gaps at the bottom of the door and keep paper, signs and decorations out of its view.
- Tell your alarm company before we test the fire alarm release. Tripping the panel can notify the monitoring station and even the fire department, so the alarm contractor needs to schedule it or put the system on test. That is why this part of the job is arranged ahead of time.
- Replace backup batteries on a schedule. A sealed battery typically needs replacing every few years, and a tired one may carry the lock for a short time instead of hours. Write the install date on the battery itself and put the next replacement on your calendar.
- If you rent, ask the landlord in writing before anyone drills the frame. A maglock may need removal when you leave, so keep a copy of the wiring diagram, the model information and any hardware that was taken out. The next tenant, and your landlord, will thank you.

Frequently asked questions
Are magnetic locks allowed on exit doors in California?
They can be, when installed to the exit rules the building code sets: a way for people to leave without special knowledge, such as a sensor and push button, release on fire alarm, and release when power fails. Details vary by building and occupancy, and your fire marshal or building department decides. We design to those rules and tell you what to confirm.
How do I secure the door after hours if power can fail?
Pair the maglock with battery backup for short outages, and consider a mechanical keyed lock for longer closures, as long as the exit rules for that door allow it. For doors that must stay locked through any outage, an electric strike or electrified lockset is a better fit. We walk you through which setup suits your door.
Can a maglock be used outdoors?
Only models rated for outdoor exposure. Rain, dust, salt air and sun wear out standard indoor magnets. Outdoor-rated units, sealed wire entries and drip protection help, and corrosion-resistant plates matter near the coast. Exterior doors also see more wind and slamming, so the mounting has to be rigid, with the wire entry sealed against water.
How do you confirm I'm allowed to modify my door?
Before we modify a door or lock, we verify ID and proof that you own, lease or manage the property, and tenants should have their landlord's approval for drilling the frame. It protects you as well as us. Our license is LCO7891, issued by BSIS, and you can verify it at search.dca.ca.gov.
How long does magnetic lock installation take?
A single door with easy cable access is often a same-visit job. Glass doors, double doors, long cable runs, fire alarm coordination and inspections take longer. We give you a realistic schedule with the quote and plan around your hours so the door isn't left unsecured. Our day starts at 6:30 a.m. every day.
How strong is a magnetic lock?
Single-door models are commonly rated around 600 pounds of holding force, and heavier-duty units reach 1,200 pounds or more. The rating assumes the plate sits flat against the magnet, so alignment matters. The door, hinges and frame also limit what the lock can resist, which is why we look at the whole opening instead of the number on the box.
How far is La Puente from your base?
La Puente is about 47 miles from our San Bernardino base, roughly 52 minutes in light traffic. Arrival time depends on traffic and on the job the technician is finishing, so we give you an estimate on the phone before you commit.
