AfterMighty Mule Access Control Installation: The North Hollywood Owner’s Guide
We stock and install Mighty Mule-compatible access control systems throughout North Hollywood, with most full installations running between $450 and $1,100 depending on which Mighty Mule model you have and how many entry devices it needs. We carry the control boards, keypads, receivers, and harnesses on the truck, so most access control work is same-day once we confirm your model. The way most North Hollywood owners discover their access control has failed is simple: the keypad lights up but the gate doesn’t move, or the remote works from the driveway but not from the street, or a tenant calls to say the gate opened itself at 3 a.m. That’s usually not the motor. It’s the control board or a wired input that’s no longer reading correctly.
Which Mighty Mule Models This Applies To
Most of the access control work we do in North Hollywood involves the FM series (FM200, FM350, FM500, FM502) and the MM series (MM260, MM360, MM371W, MM571W, MM572W). The compatibility gotcha we see constantly: Mighty Mule control boards are not interchangeable across every series. An FM500 board will not drop into an MM371W housing without a harness mismatch that causes intermittent keypad failures, and we’ve replaced boards on gates where exactly that was tried. If you’re not sure what you have, open the control box and read the label on the board itself, not the arm or the operator housing. The board label carries the actual model designation. We always recommend OEM Mighty Mule control boards over aftermarket equivalents for this specific component. The aftermarket boards we’ve tested in North Hollywood heat cycles tend to drift on the limit settings and can’t hold the auto-close timing accurately on the FM502. For keypads and receivers, a quality aftermarket part from a known supplier is fine, but the board should stay Mighty Mule if you want the gate to behave the way Mighty Mule designed it to.
Signs Your Mighty Mule Access Control Installation Is Failing
- Keypad accepts the code but nothing moves. This usually means the control board isn’t sending the activation signal to the operator, or the relay on the board has burned. We test the board’s relay output first because that’s where Mighty Mule boards fail most often.
- Remote works from 10 feet but not from the street. The receiver antenna wire may have come loose inside the control box, or the receiver itself has drifted off frequency. We see this a lot in North Hollywood where gates sit close to power lines and RF interference is constant.
- The gate opens by itself at random intervals. Almost always a failing edge sensor input or a keypad wire shorting against the gate frame. This is the one that makes people think someone is on the property, and it’s usually a $40 wiring fix, not a security breach.
- The auto-close no longer closes. The auto-close timer is part of the control board. If the gate opens but then sits there, the board’s timer circuit has likely failed, and the fix is a board swap, not a motor replacement.
- Keypad works intermittently, worse in the afternoon. Heat expansion in the keypad housing cracks solder joints. North Hollywood summers do this to Mighty Mule keypads faster than any other factor we see.
BeforeAfterReplacement Cost & What’s Included
A Mighty Mule access control installation in North Hollywood runs from $450 to $1,100 installed, with the spread driven by what you’re actually replacing. A single keypad replacement with a wired run is $450 to $600. A new control board with one keypad is $600 to $850. A full access control package (board, keypad, receiver, and two remotes) lands between $850 and $1,100. The number we quote is a flat, written price handed to you before any work starts. That’s Clause 1 of our Haven Standard and it’s not negotiable. It includes the part, the labor, the wiring check, the limit reset, the photo log of what we found and what we set, and a one-year coverage on the completed work through our 365-Day Done Right Promise. We don’t quote one price and invoice another. Every access control job in North Hollywood gets documented the same way we documented commercial access-control sites before we ever touched residential gates.
DIY or Call Us?
You can safely check a few things yourself. Confirm the breaker for the gate is on. Confirm the keypad is getting power (most Mighty Mule keypads have a backlight). Check that no wires are visibly pulled from the terminal block inside the control box. Those are diagnostics. What you shouldn’t do is open a control board and start swapping wires or jumping relays unless you know exactly what the terminal block is doing. Mighty Mule boards are low voltage, but a wrong jumper can send power where it shouldn’t go and you’ll be replacing a $200 board instead of repairing a $60 relay. We’d rather you spend ten minutes on the phone with us than buy a board you don’t need. Call (213) 566-1045 and we’ll tell you what to look at before we even schedule a visit.
FAQs
Seven to ten years is typical for an OEM Mighty Mule board in the San Fernando Valley climate. The failure curve shortens if the control box isn’t sealed properly and dust from the North Hollywood streets gets inside, or if the gate runs more than 40 open-close cycles a day. We’ve replaced boards at the six-year mark on high-use rental properties. Call (213) 566-1045 if yours is acting up and we’ll tell you whether it’s the board or something cheaper.
Sometimes. If it’s a burned relay or a bad capacitor, a board-level repair is possible, but Mighty Mule boards are potted in some areas and not every failure is serviceable. We’ll tell you straight which one you have before we recommend a repair or replacement. That’s the whole job: name what you found and name what it costs. Call (213) 566-1045 for a straight answer.
A single keypad or receiver is a one-hour job. A control board swap with a full wiring check and limit reset is two to three hours, depending on how much wiring cleanup is needed inside the control box. We do most access control installations same-day in North Hollywood because the parts are on the truck. Call (213) 566-1045 to confirm what we have in stock.
We stock Mighty Mule FM-series and MM-series control boards, keypads, receivers, and remotes on the truck, along with parts for LiftMaster, Ghost Controls, and DoorKing gates. If you have an uncommon Mighty Mule model we’ll have it ordered and installed within a few business days, and you’ll know the price before we order it. Written price, always. Call (213) 566-1045 and we’ll check the shelf while you’re on the phone.
