Linear Keypad & Intercom Repair Nationwide

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

A Linear keypad or intercom repair in Burbank typically runs $145 to $385 installed, depending on whether we’re replacing the keypad head, the intercom module, or rewiring a corroded junction. Most jobs are done same-day because we keep the common Linear series parts on the truck. The usual discovery moment is unglamorous: the keypad lights up but the gate doesn’t move, or the intercom buzzes at the house but nobody can hear you at the driveway. You stand there pressing buttons with more determination, then you call us.

The fault is almost never the whole system. Linear keypads and intercoms fail in predictable ways: a membrane that finally splits after eight summers of Burbank heat, a wire nut that turned green inside the post, a speaker cone that dried out and cracked. We name the failed part, quote the repair in writing, and leave you with photos of what we replaced. That last part matters because nobody wants to pay for the same diagnostic twice.

Which Linear Models This Applies To

We service the Linear series that show up most often on Burbank driveway gates: the AK-11 and AK-11S keypads, the AE-100 and AE-200 intercom/telephone entry systems, the AM3Plus and ACP00840 access controllers, and the older GPG and L系列 retrofit heads still running on plenty of Magnolia Park gates. If your keypad has the Linear name embossed on the lower corner or the model number printed inside the battery tray, we can match it.

Here’s the compatibility gotcha that catches people: a Linear AK-11 keypad looks nearly identical to the older AK-10, but the wire pigtail color order is different. Mix them up and the gate relay chatters without opening. We’ve fixed that mistake on gates where a previous repair swapped the wrong head. On OEM versus aftermarket: Linear-branded parts carry a one-year manufacturer warranty and fit exactly. Quality aftermarket equivalents from suppliers like North Shore Commercial Door run 20 to 30 percent less and we’ve installed hundreds without issue. The deciding factor is usually age of the controller: if it’s a pre-2005 board, we recommend OEM to avoid trigger voltage mismatches. If the controller is newer, the aftermarket head works fine and saves real money.

Signs Your Linear Keypad & Intercom Repair Is Failing

• The keypad lights up but nothing happens at the gate. The membrane still passes power to the circuit board, but the output relay has stopped closing. Common on keypads over seven years old in Burbank’s summer heat, where the relay contacts oxidize faster than in coastal air.
• Some buttons work and adjacent ones don’t. One row of the membrane matrix has torn internally. This isn’t a programming issue and reprogramming won’t fix it. The keypad head needs replacement, which our techs can do in about 40 minutes.
• The intercom hums but voice transmission is garbled. The speaker cone has dehydrated and split, or moisture got into the electronics enclosure at the driveway post. Burbank’s dry heat pulls moisture out of rubber surrounds until they crack like old tires.
• The house unit rings but pressing the door-release button does nothing. The relay on the intercom’s main board has failed, or the two-conductor run between the house unit and the gate post has a broken strand somewhere underground. We tone-test the wire before condemning the board.
• After rain, the keypad works intermittently for a day or two. Water is entering the housing through a failed gasket or a conduit fitting that was never sealed. Linear keypads are weather-rated but not waterproof, and a standing puddle inside the post is the usual culprit.

Replacement Cost & What’s Included

In Burbank, a standard Linear keypad head replacement runs $145 to $225 installed. A Linear intercom module or telephone entry board runs $225 to $385 installed. The range depends on whether we’re swapping just the keypad head or replacing the intercom’s main board plus door strike relay, and whether the mounting post needs new hardware. You’ll know your exact number before the technician starts. The written price is handed over up front, per Haven Standard Clause 1, and it doesn’t change when the job is done.

Every repair includes the part, the labor, programming the new component to your existing codes, testing the full open/close cycle, and a photo log of what was found, what was replaced, and what the wiring looked like before and after. The 365-Day Done Right Promise covers the work for a full year. We are an independent service provider and not affiliated with Linear, which means we match the part to the gate rather than steering you toward a new opener.

DIY or Call Us?

The safe checks an owner can do: look for a model number inside the keypad battery tray, verify the AC power to the panel, and look for an obvious split in the button membrane. Those steps save the diagnostic time if you write them down before calling.

Where DIY goes wrong on Linear repairs is the wiring. A keypad works at 12 to 24 volts AC, which is safe to touch, but the wrong connection order can damage the controller board on the gate opener. We’ve arrived at gates where a well-intentioned swap fried the input channel and turned a $185 keypad repair into a $600 controller replacement. The intercom side is more involved: you’re matching impedance, polarity, and relay ratings across a two-wire run. Adrian Vance grew up in Queens and studied electromechanical technology before doing this work for two decades, and his crews have logged enough Burbank service calls to know which boards tolerate mistakes and which don’t. If you want the flat price for your model, call (213) 577-1120. We’ll tell you what’s likely failed and what it costs to make right.
