We stock and install Linear keypad and intercom repair parts across San Antonio, with most jobs running between $185 and $420 installed. Same-day service is available when we have your part on the truck, which covers the majority of Linear keypads and intercom modules still in service. The typical discovery looks like this: you tap your code, nothing beeps, or the intercom picks up but your voice sounds like static to whoever is standing at the gate. Sometimes it works in the morning and quits by afternoon. That heat-related flakiness is the number one failure pattern we see in this part of Texas, and it almost never fixes itself.
Which Linear Models This Applies To
Linear’s keypad and intercom lineup splits into two main camps: the older AP-5 and AM-KP series, and the newer IEI-style access keypads Linear distributed under the NAPCO/Linear umbrella. The compatibility gotcha most San Antonio owners hit is this: an AP-5 keypad wired for a 24-volt Linear opener will not talk to a 12-volt system, and the labeling on the back plate doesn’t always make that obvious after a decade of Texas sun has faded it. We read the voltage off the existing wiring or the opener board before we quote the part, because guessing here creates a return trip and a dead gate.
For the OEM-versus-aftermarket decision on Linear specifically: the original Linear keypads have a rubber membrane that lasts reasonably well, but the aftermarket equivalents we carry for the AP-5 often use a harder plastic key face that resists San Antonio UV damage better than the original for about 70 percent of the price. We’re an independent service provider and not affiliated with Linear, which means we carry both and recommend based on what actually holds up on a south-facing gate post in full sun. If your keypad has a small plastic dome over a speaker grille, that’s an intercom-combo unit, and those almost always need the audio module replaced along with the keypad face.
Styles & brands we work with
Signs Your Linear Keypad & Intercom Repair Is Failing
- Keys beep but the gate won’t move. The keypad is receiving power and registering presses, but the relay inside isn’t closing. That relay is a $15 component inside a $90 keypad assembly, and when it fails, the whole board goes with it. We see this after 7 to 9 years on average in San Antonio’s climate.
- Intermittent operation that gets worse in direct sun. The membrane or circuit board traces expand in heat, breaking a hairline connection. It works at 8 a.m., fails at 2 p.m., works again after dark. Once this pattern starts, it won’t stop on its own.
- Intercom audio is faint, buzzing, or one-directional. The electret microphone in the intercom module degrades from humidity and heat cycling. If a visitor can hear you but you can’t hear them, or vice versa, the audio board is dying, not the wiring.
- You have to press a key two or three times before it registers. The carbon contacts under the rubber membrane are worn through at the most-used digits. Everyone’s code has a 4 and a 7 in it, so those wear first. That’s normal wear, and it means the keypad is on borrowed time.
- The keypad light stays on constantly or never comes on. A stuck LED usually means moisture has gotten inside the housing, often through a hairline crack in the case from a weed whacker or a backed-in pickup. The circuit board is corroding even though the keys still respond.
Replacement Cost & What’s Included
In San Antonio, a Linear keypad replacement runs $185 to $310 installed for most residential units. A keypad-plus-intercom combination runs $280 to $420 installed. The range depends on whether we’re matching a newer digital keypad or working around the wiring left behind by a 2012-era AP-5, and whether you want the OEM Linear part or the quality aftermarket equivalent we recommend for sun-exposed posts. Every quote includes the part, the labor, the wiring check, and the programming of all existing codes into the new unit before we leave. You get the written price before any work starts, and it doesn’t change unless we open the box and find something genuinely broken behind it, in which case we stop and call you first.
Every repair carries our 365-Day Done Right Promise: if that keypad or intercom fails within a year, the return visit is free and we make it right. Cole Rafferty built this offer because a keypad that dies again in three months is not a repaired gate, it’s a second invoice waiting to happen.

You can do two things safely without us: check the keypad’s power light, and check that the breaker for the gate opener hasn’t tripped. Those two checks rule out about a third of the no-response calls we get. After that, I’d stop, because inside the keypad housing are exposed low-voltage terminals tied to your opener board, and a crossed wire can send voltage where the board wasn’t designed for it. We’ve replaced lift arm boards that died this way, and a $40 keypad mistake turns into a $600 opener repair faster than most people expect. If you’ve got a multimeter and want to check whether the keypad is getting its expected voltage, that’s fine, but the moment it requires opening the plastic and touching terminals, we’d rather do it. Call (940) 531-3336 and tell us what it’s doing. Tell me what it’s doing wrong – I’ll tell you what it costs to fix it, in writing, before we start.
FAQs
Seven to nine years is realistic for a Linear keypad mounted on a gate post that gets direct afternoon sun in San Antonio. Shaded or covered keypads often reach 12 years. The intercom modules fail faster, usually between five and eight years, because the microphone elements degrade from humidity cycling even when the keypad itself is protected.
For membrane wear, relay failure, or audio board corrosion, no – those components are not sold separately for Linear keypads in a way that makes repair dependable. We can clean terminal corrosion and re-seat loose wiring, and we’ll do that for the service call minimum if that’s genuinely the fix. But once the board or membrane is done, replacement is the honest answer. Call (940) 531-3336 and we’ll tell you which situation you have after a quick phone diagnostic.
Most Linear keypad or intercom replacements take 45 to 90 minutes on site, including removing the old unit, checking the wiring, mounting the new one, and programming all existing codes. If we’re replacing a combination keypad-and-intercom unit with a separate intercom module, add about 20 minutes for the audio wiring and speaker adjustment.
We keep the most common Linear keypads, AP-5 replacements, and intercom modules on the truck for same-day San Antonio service. For less common configurations, particularly older intercom-only Linear units, we order the exact part and usually install it within two to three business days. We’ll confirm what’s available before we schedule, so you’re not waiting on a guess.
We test the opener board and the wiring path before we replace anything. About 20 percent of the time, the issue is a failing connection at the opener terminal or an opener board that isn’t recognizing the keypad signal. If we find that, we’ll show you the test readings and give you a new written price for the actual fix before we do anything else.
