Linear Keypad & Intercom Repair Nationwide

Linear Keypad & Intercom Repair: The San Antonio Owner’s Guide

We stock and install Linear-compatible keypads and intercoms across San Antonio, with most replacements running $210 to $480 installed depending on your model and whether we’re swapping a keypad, an intercom station, or both. The typical repair takes 45 to 90 minutes, and we arrive with the common Linear parts on the truck so the first visit usually finishes the job. Most San Antonio homeowners discover the failure the same way: the keypad lights up but the gate won’t move, or the intercom crackles and the visitor’s voice never comes through clearly.

These are among the most weather-exposed parts on a gate system, and San Antonio’s combination of intense summer heat, dust, and occasional heavy rain ages keypad membranes and intercom speaker cones faster than almost any other climate in Texas. The good news is that Linear parts are widely serviceable and we match them by model number, not guesswork.

Which Linear Models This Applies To

We repair and replace keypads and intercom hardware for the Linear access control lines most common in San Antonio: the AK series keypads (AK-11, AK-21, AK-31), the AP-5 exterior keypad, the IEI-branded Linear keypads, and the MGR/ACP intercom and telephone-entry stations that pair with Linear gate operators. If you have a Linear AE-500, AE-1000, or Teleplus system, those take a different part family and we cover those as well.

The compatibility gotcha with Linear keypads is the wiring format. Older AK-11 and AK-21 units run on a simple two-wire connection, while newer AK-31 and MGR intercom stations may use a proprietary four-wire configuration that looks similar but will not fire the operator if mismatched. We always check the sticker inside the housing for the exact model and revision before touching anything. A quality aftermarket keypad typically runs $70 to $110 for the part alone, but for Linear specifically, we’ve had better longevity with direct OEM replacements in San Antonio because the aftermarket membrane buttons don’t hold up to the UV exposure and fine limestone dust that gets into everything here.

Signs Your Linear Keypad & Intercom Repair Is Failing

• The keypad lights up but the gate won’t activate. This usually points to a dead relay inside the keypad, not a programming issue. The keypad has power, but the relay contact that sends the signal to the operator has burned out over thousands of open-close cycles.
• You have to press buttons multiple times or very hard. The membrane layer under the keypad has degraded from San Antonio heat and UV exposure. It’s not a cleaning fix; the membrane itself has broken down and needs replacement.
• The intercom rings at the house but you can’t hear the visitor. Water intrusion has corroded the speaker cone or the microphone element. We see this most often on units installed without a weather hood on north-facing walls that catch the brunt of winter storms.
• The intercom stalls mid-conversation or drops audio. The power supply inside the intercom station is starting to sag. It’s still producing voltage, but not enough to drive the amplifier cleanly under load.
• The keypad works but only sometimes, usually in the afternoon. This is classic heat-related failure in San Antonio. Components inside the housing expand and contract, and a solder joint or ribbon cable connection that’s marginal will open when the metal housing hits peak summer temperature.

Replacement Cost & What’s Included

In San Antonio, a standard Linear keypad replacement runs $210 to $320 installed, and an intercom or telephone-entry station runs $280 to $480 installed. When both the keypad and intercom are on the same failing circuit or you’re upgrading from a standalone keypad to a full intercom with call buttons, the combined job usually lands between $420 and $680. You’ll see the exact number in writing before we touch anything, and that price covers the part, labor, re-wiring, programming, and testing.

What drives the range is mostly the part itself: a basic AK-11 swap is quick modular work, while an MGR intercom with multiple resident call buttons takes longer to wire and program. We don’t pad the labor; we quote the book rate for the specific model. Every repair carries our 365-Day Done Right Promise, which means if that keypad or intercom misbehaves within a year, we come back and make it right without arguing about it.

DIY or Call Us?

There’s one safe check you can do yourself: confirm the keypad has power and the breaker for the gate operator hasn’t tripped. That takes two minutes and we’ll ask you to check before we dispatch. What we’d discourage is opening the keypad housing and probing wires. Linear keypads run on low voltage, typically 12 to 24 volts DC, so the shock risk is low, but most DIY diagnostics end with a stripped wire or a shorted terminal that turns a straightforward replacement into a re-wire.

We’ve also seen plenty of San Antonio homeowners buy a keypad online, install it, and then discover the two-wire/four-wire mismatch we mentioned earlier. If you’d rather not gamble, call us at (325) 252-5195 and we’ll match the right part to the label inside your existing unit.
