Linear Access Control Installation: The Chatsworth Owner’s Guide
A Linear access control installation in Chatsworth typically runs between $485 and $1,150 installed, depending on whether we’re swapping a failed keypad, adding a telephone entry unit, or replacing an entire controller board. We stock Linear-compatible keypads, receivers, and control boards on our trucks, so most replacements happen same-day. The way owners usually find us: the keypad works intermittently for a few weeks, then stops reading codes entirely, or the gate opens on its own at 2 a.m. because the receiver has drifted off frequency. By the time the call comes in, the part has usually been failing quietly for a month.
We’re an independent gate repair company, not a Linear dealer or affiliate. That matters because we’re not here to steer you toward replacing the whole system. We match the failed part, quote the installed price before we touch anything, and leave you with a photo record of what we found and what we installed.
Which Linear Models This Applies To
Linear’s access control line spans a few distinct generations, and the compatibility picture is where most Chatsworth homeowners get lost. The older Multi-Code and MegaCode series (AP-5 keypads, MGT gate transmitters, 3089-series receivers) operate on 318 MHz. The newer ACT-series and Linear Pro Access units run on a completely different protocol. A keypad from one generation will not talk to a receiver from the other, even though both say “Linear” on the housing.
The fastest way to identify what you have: look at the back of the keypad or the side of the receiver housing. There’s a model number stamped into the plastic or printed on a faded sticker. AP-5, AK-11, AM-KP, DVS, and ACT-31B are the common ones we see in Chatsworth. If the label is gone, we pull the unit and read the board revision number, then cross-reference it before ordering anything.
On the OEM versus aftermarket question for Linear specifically: Linear OEM parts are reliable, but the keypads have a known weak point, which is the membrane seal. After a few Chatsworth summers with UV and heat cycling, the membrane cracks, moisture gets in, and the board corrodes. We stock both OEM and a quality aftermarket line that uses a thicker silicone membrane rated for direct sun. For most residential installs, the aftermarket keypad lasts longer here. For receiver boards and controller logic, we use OEM. That’s the honest split.
Signs Your Linear Access Control Installation Is Failing

- Keypad accepts some codes but rejects others. This is rarely a programming issue. It’s usually corrosion on the keypad ribbon connector or worn contact pads under the membrane. The board reads partial inputs and drops others.
- Gate opens without anyone pressing anything. A receiver that has drifted off its tuned frequency will occasionally lock onto stray RF from garage door openers, wireless doorbells, and older cordless phones. In dense Chatsworth neighborhoods, that interference is constant.
- You have to stand closer than you used to. Transmitter range drops when the receiver’s antenna connection degrades or the transmitter battery weakens. If a fresh battery doesn’t restore range, the receiver front-end is failing.
- Keypad lights up but the gate doesn’t respond. The keypad is sending a signal, but the receiver isn’t decoding it. Common cause: mismatched code format after a power surge, or the receiver’s relay has welded open.
- Humming, clicking, or a burning smell near the control box. A failing transformer or capacitor on the control board. This one needs attention quickly, not just because the gate stops working, but because a failing transformer can overheat.

AfterReplacement Cost & What’s Included
Here’s what Linear access control installation actually costs in Chatsworth, installed, with the written price in your hand before we start:
- Keypad replacement (AP-5, AK-11, or compatible): $285-$460 installed, depending on whether we’re running new wire or reusing the existing run.
- Receiver replacement (3089-series or newer): $290-$480 installed. The receiver itself is the cheap part; the labor is in matching the code format to your existing transmitters.
- Full controller board replacement: $425-$750 installed, depending on the model and whether the enclosure is reusable.
- Complete keypad-plus-receiver swap with new transmitters: $680-$1,150 installed, which includes reprogramming every remote and testing the safety edges.
The range depends on two things: whether the existing wiring is intact, and whether your Linear unit is old enough that we’re also replacing corroded connectors. You get a written flat price before any work starts. You get a photo log of the old part, the new part, and the finished install. And you get our 365-Day Done Right Promise: if it fails within a year, we come back and fix it. No charge, no argument.
DIY or Call Us?

Here’s the honest split. You can check your transmitter batteries, confirm whether the keypad backlight comes on, and read the model number off the housing. Those three things tell us a lot before we even arrive. What you should not do is open the control box and start swapping terminals. Linear control boards run 24-volt low-voltage power, which won’t shock you, but the relay side often carries 120-volt line voltage for the gate motor. Short the wrong two terminals and you’ll be replacing a $400 board instead of a $50 keypad.
If the keypad membrane is cracked or the receiver is doing anything intermittent, that’s a parts diagnosis job, not a YouTube tutorial. Call us at (661) 495-2023 and we’ll read the model number with you over the phone, tell you what the likely failure is, and quote the installed price before we dispatch.
FAQs
A Linear keypad in Chatsworth typically lasts 5 to 8 years before the membrane seal fails, with south-facing keypads in full sun often failing closer to the 5-year mark because UV degrades the silicone faster. If your keypad is over 6 years old and starting to miss inputs, replacement is more economical than repair. Call (661) 495-2023 and we can confirm the failure over the phone.
Sometimes, but not often enough to recommend it. If the failure is a corroded ribbon connector, we can clean and reseat it and get you another year or two. If the membrane is cracked or the board shows water damage, repair is a temporary patch, and you’ll pay twice for the same part. We’ll tell you which one you have before we quote anything.
Most Linear keypad or receiver replacements in Chatsworth take 45 to 90 minutes on site, including reprogramming transmitters and testing the safety edges. A full controller board swap with new wiring can run 2 to 3 hours depending on the condition of the existing conduit. We’ll give you a written time estimate with the price.
Yes. Our Chatsworth trucks carry Linear-compatible keypads (AP-5 and AK-11 form factors), MegaCode receivers in both 318 MHz and 390 MHz, and controller boards for the most common Linear series. We also stock compatible parts for LiftMaster, Mighty Mule, and Ghost Controls systems, so if your gate motor is a different brand but the access control is Linear, we can handle both on the same visit. Call (661) 495-2023 and we’ll confirm we have your part before we roll out.
