Linear Access Control Installation: The San Fernando Owner’s Guide
Most Linear access control installation work in San Fernando comes down to a failed keypad, a dead receiver, or a circuit board that stopped reading the antenna. We stock Linear-compatible parts on the truck and install them for a flat, written price, typically between $340 and $780 depending on which component failed and whether the wiring was compromised. If you’re calling before noon, we can usually have a technician to your San Fernando driveway the same day.
The way most people find us: the keypad works when it wants to, the remote stopped opening the gate from the street, or the gate opens for every car in the neighborhood except the one that belongs there. And if the gate opened when it felt like it, that’s not a gate, that’s a suggestion.
Which Linear Models This Applies To
We install and replace access control parts for the Linear product lines most common in San Fernando residential gates: the APeX series, the Multi-Code receivers, the MDR and MGT gate operators, and the older MegaCode wireless keypads that are still running on plenty of driveways off Brand Boulevard and San Fernando Road. If you’re not sure which one you have, we can read the model label on site, but here’s a useful shortcut: Linear keypads and receivers from the MegaCode and Multi-Code families are cross-compatible with each other, so an older keypad doesn’t always mean you need to match it to an identical unit.
One compatibility gotcha that comes up often in San Fernando heat: the older Linear AM-KP keypad housings crack and yellow badly, and the replacement shells are no longer manufactured by Linear. Owners will sometimes buy a used shell and find the internal board doesn’t seat correctly. We usually recommend replacing the whole keypad with a current MegaCode MGT-KP unit, which reads fine with the original receiver and costs less than most people expect.
The OEM-versus-aftermarket question is straightforward for Linear parts. We install genuine Linear and Nortek components when they’re available, and we’ll use a quality aftermarket equivalent only when it’s plug-compatible and we can show you the spec sheet. We’re an independent gate company in San Fernando, not a Linear dealer or affiliate, so our recommendation is based on what fits your system and what’s actually in stock, not what we’re obligated to sell.
Signs Your Linear Access Control Installation Is Failing

- The keypad accepts the code sometimes, not others. Usually a cold solder joint on the keypad’s board or corrosion on the ribbon cable connector. San Fernando’s dry heat makes this failure mode worse, because connection points contract and expand less predictably than they would at the coast.
- The remote works from 20 feet but not from the street. That’s almost always the receiver antenna, which on Linear receivers is a small wire that gets pinched or broken inside the operator housing. We re-solder or replace it in under a half hour.
- The gate opens for random cars or doesn’t respond at all. This points to a failed MegaCode receiver chip, which handles the rolling-code authentication. A dead chip means the receiver hears the signal but can’t verify it, so the operator ignores everything.
- The keypad lights up but the gate doesn’t move. If we’ve confirmed the operator itself is fine, this is usually a wiring fault between the keypad and the receiver or the receiver and the motor terminals. We photograph every connection before we touch anything, which speeds up the diagnosis by a lot.
- You have to enter the code twice every time. This is a failing relay inside the receiver, and it’ll get worse. The relay is cheap; the labor to swap it is about half an hour. By the time it takes three tries, the unit is usually gone.
Before
AfterReplacement Cost & What’s Included
In San Fernando, Linear access control installation work usually lands in these ranges: keypad replacement runs $240 to $390 installed, receiver replacement runs $280 to $460, and a full keypad plus receiver swap runs $420 to $680. What moves the number is whether the wiring is intact, whether the operator needs a new antenna mount, and whether we’re matching an existing system or adding a second entry point.
| Component | Typical Installed Price (San Fernando) |
|---|---|
| MegaCode keypad replacement (single) | $240 – $390 |
| MegaCode receiver replacement | $280 – $460 |
| Keypad + receiver (full refresh) | $420 – $680 |
| Wiring repair / antenna re-solder | $90 – $180 |
Every quote includes the part, the labor, and the documentation. You get the written price before we touch anything, and when we leave you get a photo log of the old part, the new part, and every connection we made. Under the Haven Standard, Clause 1 is the written price, and Clause 4 is the photographic evidence. Both apply on every single visit, no exceptions.
The installation work carries our 365-Day Done Right Promise: if the part fails or the install isn’t right within a year, we make it right at no charge.
DIY or Call Us?

You can safely check a few things before calling. Confirm the keypad has power, check that no wire has pulled loose from the antenna, and note exactly when the failure happens (after rain, in the morning, from one specific remote). What you should not do is open the operator housing and start moving wire connections around. The receiver board sits next to live motor terminals, and a slipped screwdriver can take out the receiver, the board, and the motor in one motion.
The other reason to call us instead of ordering a part online: your gate’s access control is the security boundary for your property. When a San Fernando homeowner installs a keypad and gets the wiring polarity reversed, the gate usually still opens, which seems fine until it doesn’t close and the homeowner doesn’t notice for six hours. We test every installation for open, close, and obstruction response before we call it done.
If you’re not sure what’s wrong, call us at (747) 260-0589. We’ll tell you what we think over the phone, and the quote we write when we arrive is the price you pay. Written, flat, before the first tool comes off the truck.
FAQs
In our experience across San Fernando, most Linear keypads and receivers last 7 to 10 years before the solder joints or relay give out, but units mounted in direct afternoon sun on west-facing gates sometimes fail by year 5. The heat accelerates the plastic aging and the internal connection fatigue. If your unit is past the 7-year mark and acting up, replacement usually beats repair on cost.
Sometimes, yes. If the issue is a broken antenna wire or a failed relay, we can repair the board for under $180. If the receiver chip itself has failed, it’s a replacement. We’ll show you the board and explain which one you’re dealing with before quoting anything. Call (747) 260-0589 and we’ll walk you through the symptoms to get a better idea.
Most keypad or receiver swaps are done in 45 to 90 minutes. If we’re rewiring the run from the keypad to the receiver or installing a second keypad at a new entry point, plan on 2 to 3 hours. We write the time estimate on the quote before we start.
Yes. We carry MegaCode and Multi-Code keypads, receivers, antenna wire, relays, and connector harnesses on every truck we send into San Fernando. We also stock compatible parts for LiftMaster, Mighty Mule, and Ghost Controls systems, so if the failure turns out to be something else, the truck is usually still ready for it. If we need to order a specific board, we’ll tell you the lead time and the exact part number before you commit to anything.
