Linear Keypad & Intercom Repair Nationwide

Linear Keypad & Intercom Repair: The Carrollton Owner’s Guide

Linear keypad and intercom repair in Carrollton typically runs between $185 and $420 installed, depending on whether we’re replacing the keypad face, the intercom board, or the entire housing. We stock Linear-compatible keypads and intercom modules on the truck, so most calls are completed same-day. The way most Carrollton homeowners discover the part has failed is simple: the gate works fine from the remote but won’t respond to the keypad, or the intercom rings once and then goes silent.

What we find underneath is usually a corroded ribbon cable, a worn membrane switch, or a power supply that’s been cooking in the Texas sun longer than it was ever rated for. Linear built these units to last, but the weather here in Carrollton doesn’t read spec sheets. Heat breaks down the adhesive layers inside membrane keypads. Moisture creeps into the housing through micro-cracks in the bezel. And then one afternoon the gate just doesn’t open, and you’re standing at the keypad pressing buttons harder, which doesn’t help. We know. We’ve been there, tools in hand, more times than we can count since 2014.

Which Linear Models This Applies To

If you have a Linear gate opener, the odds are good we can match the keypad or intercom on the first visit. The most common units we repair across Carrollton are the Linear AK-11, AK-11B, and AM-KP keypads, plus the ACP00879 and ACP00880 series access controllers. On the intercom side, we regularly service Linear AE-100, AE-200, and the AESS series telephone entry systems. The older Multi-Code 3089 and 4120 keypads also fall under this umbrella, because Linear absorbed Multi-Code and kept the part numbering alive for years.

Here’s the compatibility gotcha owners need to know: just because it says “Linear” on the keypad does not mean it will talk to your receiver. Linear has used at least three different radio protocols across its keypad line over the last twenty years. The AK-11B, for example, transmits on 318 MHz, but if your receiver is an older 310 MHz Multi-Code unit, you can mate them only if the receiver supports multi-frequency learning. We check the model number stamped on the back of the keypad and the receiver frequency before ordering anything. An aftermarket keypad will work in most residential setups and saves money upfront, but on Linear we lean toward OEM when the customer has a Linear DVS or MEGA CODE receiver, because the learn-mode handshake is tighter and fewer callbacks happen. When the aftermarket makes sense, we say so and price accordingly. We’re an independent company; we’re not married to any manufacturer’s catalog. LiftMaster, Mighty Mule, Ghost Controls, Linear. They all make parts, and we stock the ones that fail most.

Signs Your Linear Keypad Is Failing

• You press buttons and nothing happens, but the remote still works. This narrows the problem to the keypad itself rather than the gate motor or receiver. Usually it’s a dead battery, a corroded contact pad, or a failed membrane. If a fresh battery doesn’t fix it, the keypad needs bench testing.
• Some numbers work, others don’t. A membrane keypad with dead keys means the conductive traces under those specific buttons have worn through or oxidized. You can’t clean individual traces. The keypad gets replaced.
• The keypad beeps but the gate won’t open. This points toward a programming loss or a receiver mismatch. We see it after power outages and lightning strikes, which happen often enough in Carrollton that surge protection on the gate circuit is worth considering.
• The intercom rings once, then cuts out. That’s commonly the AESS series speaker or a failing power supply cap. The board sees the call, opens the channel, and then browns out. Replacement is straightforward, but the underlying power issue has to be corrected or the new board fails the same way in six months.
• Water inside the housing, fog on the display, or rust on the terminals. Once moisture breaches the seal, the board is running on borrowed time. We don’t patch water-damaged keypads. We replace the housing and address how the water got in, which on older Carrollton gates near the Arbor Hills corridor is often a mounting orientation problem from the original install.

Replacement Cost & What’s Included

In Carrollton, a Linear keypad replacement with parts and labor runs from $185 to $280 for a standard AK-11 or AK-11B. A full Linear intercom or telephone entry replacement runs from $320 to $420 installed, depending on whether the power supply and wiring need attention. If your unit is a newer AESS series with video, the upper end of the range applies, because parts are pricier and the wiring check takes longer. If it’s a worn keypad on an existing working system, you’re at the lower end.

Every price is written down before we touch anything. That’s the flat number, parts and labor together, handed to you on paper before the first tool comes out. If we find something unexpected once the housing is open, we stop and bring you a new written number. No surprises at the end, no “well, it turned out to be more.” Under our Haven Standard, the written price is non-negotiable after the fact. The work carries the 365-Day Done Right Promise: if the keypad or intercom we installed fails within a year, we make it right at no additional charge. You also get a photo record of what we found, what we replaced, and how the new part was wired, left with you and filed in the job record.

DIY or Call Us?

Here’s the honest split. If your Linear keypad has a dead battery, change it. That’s a twelve-dollar fix and takes two minutes. If the keypad is beeping but not opening the gate, you can try a reprogram, but Linear’s learn-mode sequence varies by receiver, and doing it wrong can wipe the codes you already have. If there’s water inside the housing, stop. Disconnect the power to the gate system at the breaker before you touch the keypad. A wet low-voltage keypad is not a shock hazard like a line-voltage panel, but the control board behind it is, and shorting it with a screwdriver while it’s live turns a $200 repair into a $600 board replacement.

What goes wrong when owners open the housing themselves: they pull the ribbon cable too hard and crack the connector; they re-seat the board with a static charge on their hands; they tighten the bezel screws too far and strip the mounting posts. The part itself isn’t dangerous to replace when the power is off. But matching the right part to the right receiver, and doing it without killing the board, is where the money goes. If you’d rather have it done once and documented, call us at (817) 778-4585. We bring the right part and the paperwork.
