Linear Keypad & Intercom Repair Nationwide

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

We repair and replace Linear keypads and intercoms across Dallas, and most jobs run between $210 and $460 installed, depending on whether you need a keypad swap, a full intercom station replacement, or a wiring repair at the gate post. Same-day dispatch is realistic for keypad-only failures when the part is on the truck, which it usually is. The way owners discover this problem is almost always the same: the keypad looks fine, but it stopped reading codes, or the intercom produces static where the visitor’s voice used to be, or the outside station works intermittently after rain.

If your Linear keypad lights up but won’t open the gate, or the intercom has degraded to a hum, you’re not looking at a full automation replacement. You’re looking at one failed component, and it’s a part we diagnose in writing before we touch a screw.

Which Linear Models This Applies To

This repair scope covers the Linear access-control lines we see most often on Dallas driveways and private entries: the AK-11 and AK-21 digital keypads, the AM-KP keypad models, the RE-1 and RE-2 telephone entry systems, and the AP-5 and AE-1000 intercom/entry stations. Many Dallas properties also run the older Linear AE-500 and AE-2000 access controllers paired with a remote keypad, and those have their own failure patterns we’ll get to.

Identifying your part matters before we can quote a written price. On the keypad, the model number is printed on a label inside the housing or on the back plate. On the intercom, it’s usually on the bottom edge of the enclosure. If the label is gone, we go by wire count and keypad dimensions, which is accurate enough that Adrian Vance can often ID the unit from a photo before dispatch. One Linear-specific gotcha: the AK-11 and AK-21 look nearly identical from the outside, but the AK-21 is a 12-volt DC unit and the AK-11 runs on 24-volt AC. Wiring a replacement onto the wrong voltage works for about a week before it burns out the relay, and we’ve seen that exact mistake from handyman installs in Plano and Richardson. For OEM versus aftermarket parts, we use genuine Linear replacements for the controller and relay boards because the tolerances on those matter. For keypads, a quality aftermarket equivalent is fine when the customer wants to save money and we confirm the voltage spec.

Signs Your Linear Keypad & Intercom Repair Is Failing

• Keypad backlight is on, but codes don’t open the gate. This usually means the relay on the control board has failed, or the keypad’s output transistor is dead. The keypad thinks it’s working, which is why it’s deceptive. We’ve replaced dozens where the homeowner assumed the gate motor was the problem.
• The intercom station buzzes, but you can’t hear the visitor. That is the speaker driver failing or the audio amplifier on the station board. Dallas heat accelerates this, especially on west-facing gate posts where the enclosure hits 130-plus degrees in July.
• The keypad works sometimes, usually after rain or cold nights. This is a moisture intrusion issue at the keypad’s weather seal or a corroded connection where the wire enters the gate post. It’s the most common intermittent failure in Dallas, and the fix is often a new keypad gasket plus re-terminating the wiring.
• Visitor can hear you, but you can’t hear them through the intercom. That points to the microphone element in the outdoor station. Linear used an electret mic in most residential intercoms and it degrades with age, especially in humid Texas summers.
• The keypad accepts the first digit, then freezes or goes dead. This is a power supply problem feeding the keypad, not the keypad itself. The processor resets mid-entry. We trace the voltage at the keypad terminals to confirm it before quoting a part replacement.

Replacement Cost & What’s Included

A Linear keypad replacement in Dallas typically runs $210 to $320 installed, which includes the part, the labor, and the programming of your existing access codes into the new unit. A full intercom station replacement, like the outdoor speaker/mic assembly, is $280 to $460 depending on whether we’re replacing a standalone station or one integrated with a camera and keypad. Wiring repairs between the house and gate, or between the keypad and main control board, add $75 to $160 when the damage is from moisture or UV-brittled insulation.

Every price is written and handed to you before any work starts. That’s Clause 1 of The Haven Standard and it isn’t a courtesy, it’s the way the company has operated since 2014. You get the part number, the labor cost, and the total before we pick up a tool. If the existing codes matter to you, we transfer them and test each one at the keypad before we leave. All work is covered by the 365-Day Done Right Promise: if it fails within a year, we make it right at no charge.

DIY or Call Us?

There are two things an owner can safely check before calling. First, confirm the keypad has power by holding any key and watching for a backlight. Second, confirm the gate motor itself still operates from the inside control or your remote. If the remote opens the gate but the keypad doesn’t, the keypad is the problem, not the motor. That’s the extent of what we recommend doing yourself.

This is low-voltage work, so it won’t throw you across the yard, but the reason to call us isn’t danger. It’s the fact that Linear keypads and intercoms are wired into the same board that controls your gate’s open and close limits. A wire landed on the wrong terminal can send the gate into a full-open cycle or disable the photo-eye safety circuit. We’ve corrected enough botched DIY keypad swaps to know the pattern: the gate opens, the keypad works for two days, then the controller faults because a wire was landed on the wrong screw. Call (469) 299-5902 and we’ll have a background-checked technician out with the right part and a written price before you open the gate post.
