Magnetic Lock Installation in Riverside
Short answer: Magnetic lock installation in Riverside puts an electromagnet on the door frame header and a steel armature plate on the door. Power holds them together; cut the power and the door is free. We choose the holding force, mount both parts squarely, wire the power supply and release devices, and test that the door opens every way it must.

People are sometimes surprised to learn that a magnetic lock is the opposite of fail-secure. It holds only while powered, so a blackout, a tripped breaker or a fire alarm opens the door. That is a feature for exit safety and a risk for security if nobody plans for it. Our approach to magnetic lock installation in Riverside treats both sides of that. We make sure the door can always be exited, then add backup power, a separate mechanical lock where the rules allow it, and monitoring that keeps the door as secure as the building permits.
How this works in Riverside
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.
What we can do on-site
- Inswing doors, brackets and offset mounts. Bracket choice is where installs go wrong. Inswing doors, deep headers and thick doors all change the geometry, and a cheap bracket that flexes gives up holding force. We use rigid kits, check them against the actual door, and avoid stacking parts that introduce play.
- Frameless and tempered glass doors. Frameless glass has no stile, no hole and no margin for error. A glass-door bracket holds the armature plate with a clamp and rubber gaskets, and the magnet goes on a header, a sidelight or a mounting plate. We check glass thickness and pivot condition, because a sagging pivot defeats any magnet.
- Double doors and paired magnets. A pair of doors can use two single magnets, a double-door unit on a shared header, or a magnet on one leaf with flush bolts on the other. The best choice depends on which leaves open, how often, and what the code expects. We map that out during the survey.
- 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.
- Readers, keypads and controllers. A maglock pairs well with almost any credential: cards, fobs, PIN codes, mobile credentials. What matters is that the controller's relay is rated for the lock and that the exit path never depends on that relay. We match the pieces, then test each credential type.
What's different about Riverside
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.
Warehouse and industrial doors are heavy, often outswing steel on thin frames, and exposed to forklifts, dust and temperature swings. A maglock needs solid anchoring and a plate that stays aligned despite vibration. Many pedestrian doors on industrial sites in Riverside County fall under stricter life-safety rules because workers need dependable exits, so we check that early and may recommend a different lock.
Campus-area buildings use maglocks on study lounges, labs, maker spaces, bike rooms and glass-front student services offices. Heavy traffic and slamming are hard on plates and brackets, so we favor rigid mounting and bond sensors that report a magnet that isn't seating. Credentials turn over every term, which suits cards or mobile access better than keys. We also plan installation windows around the semester calendar.
Example situations
- In a two-story office building, a corridor door leads to a stair enclosure, and someone wants card access on it. Stair doors have specific rules because people must be able to leave the stair in an emergency. We'd talk with the property manager and the fire marshal before touching the door, since the right answer may be a different lock or no change at all.
- For example, a fitness studio has double glass doors off a shared hallway near Riverside Community Hospital. Members badge in, and the owner wants evening entry without handing out keys. We'd fit a magnet on each leaf, wire both to a card reader and controller, add sensors and a push button inside, and connect a fire alarm relay with the landlord's alarm contractor.
- 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.
- Suppose a heavy glass door slowly sags on its pivots, so the plate no longer meets the magnet squarely and the door pulls open with a firm tug. The lock isn't weak; the door has moved. We'd adjust or replace the hardware that holds the door, realign the plate, and confirm full contact before blaming the magnet.
Step by step with Julian's Locksmith
- Survey the door, header and exit path. We look at the door type, how it swings, the header and frame, the glass, the closer and the hinges. Then we trace how a person leaves: where they stand, what they reach for and what could stop them. The exit comes first because everything else depends on it.
- Design the release path and quote. We also confirm authority to modify the door. We need ID and proof that you own or manage the property, and tenants should have their landlord's permission, since mounting a magnet means drilling the frame.
- Mount the magnet and armature plate. The magnet face and plate must meet flat. We check the gap, adjust the plate until contact is even, and clean both faces so no paint, dust or tape sits between them. Small gaps cost large amounts of holding force.
- 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.
How we quote the job
- Exit devices and fire alarm interface. Expect the exit chain to be a substantial part of the quote. Sensors, buttons, signs, relays and testing take time. Cutting corners here is how doors fail inspection or trap people, so we quote it plainly instead of hiding it in a lump sum.
- Power supply, backup and controller. A single-door keypad system is a small project; a networked controller with software and several doors is larger. Credentials such as cards and fobs are an ongoing cost. We plan the system so it can grow without redoing the wiring.
- Cable route and header access. Short, accessible cable runs through a drop ceiling go quickly. Long runs, finished walls, concrete or fire-rated barriers take longer and may need other trades. We trace the route during the survey and quote the cabling as its own line.

Advice before you book
- Test the exit button and sensor monthly. Press the button and confirm the door releases; walk toward the door from inside and confirm the sensor does the same. Put the test on a calendar, because exit devices are exactly the part nobody notices until it fails.
- Don't plan a maglock for a door that must stay latched in a fire. Rated doors, stair enclosures and some corridors have specific rules. Ask your fire marshal or building department before you buy hardware, and tell your installer what the door is and where it leads.
- 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.
- Take photos of the top of the door, the header above it and the edge of the door. Include any glass stops, closers or conduit in view. With those we can often pick the bracket kit and the mounting approach before we arrive.
Common errors that cost time and money
- 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.
- Installing the lock without an exit plan. A maglock with a card reader and nothing else can trap people if the controller fails while the lock stays energized. A sensor, push button and fire alarm release aren't optional on exit doors, and an inspector will look for them.
- Powering the lock from a cheap plug-in adapter. Adapters sag, overheat and fail, and when they do the door opens or the lock buzzes. Use a fused, regulated supply with suppression, in a ventilated spot, with labeled wiring. Voltage that sags under load also weakens the magnet, long before the supply fails outright.

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 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.
Why does my door seem to stick after the magnet turns off?
That is residual magnetism, often caused by a worn or rusted armature plate, an over-tightened plate, or a plate with no flexible mounting. Cleaning the faces, loosening or replacing the plate and checking alignment usually cures it. It can also point to a failing lock or voltage problems, so we test the magnet before replacing parts.
Does a magnetic lock connect to the fire alarm?
Where a fire alarm system exists, the maglock normally drops out when it sounds, using a relay in the lock's power line. Some buildings add sprinkler or smoke detector release. The panel connection may need a licensed fire alarm contractor, and the release should be tested with them. We coordinate so testing doesn't surprise your alarm monitor.
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.
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 far is Riverside from your base?
