Linear Keypad & Intercom Repair Nationwide

Linear Keypad & Intercom Repair: The League City Owner’s Guide

We stock and install Linear keypad and intercom repairs throughout League City, with most jobs running between $185 and $420 installed depending on whether we’re replacing a membrane keypad, a full housing, or an intercom module. Same-day service is available for most keypad failures since we keep the common Linear parts on the truck. The way most League City homeowners find us is when the keypad still beeps but won’t open the gate anymore, or the intercom crackles so badly no one can understand a word from the driveway. By the time we arrive, they’ve usually been typing the code twice, three times, then walking around to the other side to trip the exit loop just to get in their own driveway.

If your Linear keypad is dead, intermittent, or the intercom sounds like it’s underwater, we can typically match the exact part to your model and have it working the same day. Here’s what that actually looks like.

Which Linear Models This Applies To

Linear gate keypads and intercoms show up on a wide range of residential and light commercial gates across League City, but the parts are not interchangeable between series. The most common units we work on are the Linear AK-11, AK-21 and AK-31 keypads (the -11 is a single-unit digital keypad, the -21 uses a separate control box, and the -31 is the backlit version), plus the Linear AM-KP and MGTKP units that came paired with Mighty Mule and Linear gate openers. Intercom jobs are usually the Linear AE-100, AE-200, or AE-500 series telephone entry units, which are more common on HOA gates near South Shore Harbour and gated communities off Egret Bay Boulevard.

The key gotcha with Linear is that keypad wiring varies by generation. Older AK-11 units from before roughly 2012 used a four-wire hookup, while newer revisions shifted to a different common terminal layout. If you wire a new keypad to an older control board without checking the revision, the keypad powers up but won’t trigger the open relay. We check the board revision and the keypad label before anything gets wired. For OEM versus aftermarket: we generally recommend genuine Linear or Linear-compatible OEM parts for telephone entry systems because the intercom audio quality on cheap aftermarket units is often unacceptable at driveway distances. For simple digital keypads, quality aftermarket equivalents from companies like North Shore Commercial Door work fine and save $40 to $80.

Signs Your Linear Keypad & Intercom Is Failing

• Keypad beeps but the gate doesn’t open. This usually means the relay in the keypad or control board isn’t closing, or a wire has worked loose at the terminal. The beep tells you the keypad itself has power, so the problem is downstream.
• Intermittent access, especially after rain or humidity swings. League City humidity and Gulf Coast salt air get into keypad housings through cracked gaskets and corrode the contact traces. A keypad that works in the morning but not the evening is classic corrosion.
• Intercom audio is garbled, quiet, or one-sided. Most Linear intercom failures are the speaker element or microphone degrading from moisture. It’s rarely the wiring, and replacing the whole unit when a $40 speaker was the issue is the mistake we see most from other companies.
• Buttons require hard presses or multiple attempts. The silicone membrane under the keypad face loses rebound over time, especially on west-facing gates in full sun. UV and heat cycles in Texas kill these membranes within 5 to 7 years.
• Keypad is fully dead with no backlight or beep. Before assuming the keypad failed, check the low-voltage breaker or the transformer. A dead transformer is a $35 fix, and we see it frequently at League City homes where the transformer was installed outdoors near sprinkler heads.

Replacement Cost & What’s Included

For League City Linear keypad and intercom repairs, here are the installed price ranges you should expect:

• Digital keypad replacement (AK-11, AK-21, equivalent): $185 to $260 installed
• Backlit keypad replacement (AK-31, MGTKP): $240 to $320 installed
• Keypad membrane or button pad only: $95 to $140 installed
• Telephone entry intercom repair (speaker, mic, or module): $190 to $340 installed
• Telephone entry full unit replacement if beyond repair: $420 to $650 installed

The range depends on whether we can salvage your existing housing, what generation of Linear board you have, and whether the wiring is sound or needs re-terminating. Every job follows The Haven Standard: you get a written price before we touch anything, so there’s no surprise invoice at the end. The work is covered by our 365-Day Done Right Promise, which means if the repair isn’t right within a year, we make it right at no charge, no argument. Before we leave, you get a photographed record of what was found, what part number was installed, and what the keypad does now that it didn’t before. That’s Clause 4, Evidence on every job, and it’s included on every visit.

DIY or Call Us?

There are a few safe checks you can do yourself before calling us. Confirm the keypad is getting power – a dead transformer or tripped GFCI is a quick fix. Check that the wire connections at the keypad are tight and not green with corrosion. If you have a multimeter, you can verify the keypad’s relay is actually closing when you enter the code. That’s where DIY should stop. The danger isn’t the keypad itself; the danger is downstream at the gate operator, where a wrong wire landed on the wrong terminal can send 120VAC where low voltage should be or fry a control board that would cost more to replace than the original repair. If the board looks anything other than clean and dry, or the wiring doesn’t match the diagram, call us at (346) 787-1751. We’ll give you a written price to re-terminate the wiring or replace the board, and you’ll know the cost before we start.
