Linear Keypad & Intercom Repair Nationwide

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

Linear keypad and intercom repair in Dallas typically runs $145 – $385 installed, depending on whether we’re replacing a weather-worn keypad, a failed intercom board, or the full entry station. We stock Linear-compatible keypads and intercom parts on our trucks, so most repairs happen same day. How owners usually find us: the keypad lights up but won’t send a signal, the intercom buzzes but you can’t hear anyone, or the whole unit went dark after a North Texas thunderstorm rolled through.

We see it constantly in neighborhoods like Preston Hollow, Lakewood, and M Streets. A Linear keypad that’s been cooking in direct Texas sun since 2015 finally gives up in August, right when your teenager’s carpool buddy is locked out on the curb. The part itself is usually inexpensive. The job is knowing which Linear series you have, matching the right keypad to the right control board, and not frying the new part during installation.

Portcullis Gate Repair Dallas is an independent gate service company. We’re not affiliated with Linear, but we’ve repaired and replaced their keypads and intercoms long enough to know the product line inside out. Dean Prescott, our owner, will tell you something he learned early: most Linear keypad failures aren’t mysterious at all. “Tell me what it’s doing and what it stopped doing, that’s usually ninety percent of the diagnosis right there.”

Which Linear Models This Applies To

Linear’s keypad and intercom line breaks down into a few distinct families, and the part you need depends on which one is mounted at your gate.

The AK-11 is the most common exterior keypad we replace in Dallas. It’s a single-gang, die-cast keypad that pairs with Linear’s MegaCode receivers. If you’ve got the older AM-KP keypad or a AE-500 telephone entry system, that’s a different repair path: the AE-500 uses a modular board that can sometimes be rebuilt rather than fully replaced, depending on what the lightning took out.

For intercoms, the RE-2 and AE-2000 series show up on a lot of Dallas-area residential estates, particularly in Highland Park and University Park. These are two-wire systems where the intercom station at the gate talks back to a handset inside the house. If the outdoor station gets moisture in the mic or the board, the call function fails while the keypad still works.

The compatibility gotcha: newer Linear keypads are not automatically backwards-compatible with older receivers. A keypad marked “MegaCode” won’t just drop onto a system wired for the older Multi-Code format without a receiver swap. That’s the kind of thing that turns a simple Sunday afternoon YouTube project into a Monday afternoon service call with us. Before you order a part online, check the label on the back of your keypad, or send us a photo. We’ll tell you which one you need.

Signs Your Linear Keypad & Intercom Repair Is Failing

• Keypad lights up but the gate won’t move. The keypad’s processor is still alive, but it’s no longer transmitting a recognized code. This usually means the onboard transmitter has drifted off frequency or the programming got wiped. It’s rarely the gate operator’s fault.
• Buttons need to be pressed twice, or pressed hard, or in a particular mood. That’s a worn membrane pad. Linear keypads use a flexible membrane over the switch contacts, and in Dallas heat that membrane gets brittle. Once it cracks, moisture gets in and the contacts corrode.
• Intercom buzzes but you can’t hear anyone at the gate. The call function works, meaning power is fine, but the audio circuit has failed. On the AE-series units, that’s usually the microphone or a blown capacitor on the intercom board. You’ll hear the buzz, the visitor hears nothing useful.
• Gate opens on its own, or not at all, after a storm. Lightning doesn’t need a direct hit. A surge from a nearby strike traveling through the low-voltage wire will take out a Linear keypad or intercom board faster than you’d believe. This is a very common Dallas pattern, especially in areas with above-ground utilities like parts of Richardson and Mesquite.
• You can hear the click but the gate ignores it. The keypad relay is firing, meaning the keypad probably works, but the operator’s receiver isn’t accepting the signal. This could be a receiver issue or a wire that’s worked loose in a junction box. Either way, it’s worth checking before you buy a new keypad.

Replacement Cost & What’s Included

In Dallas, you should expect most Linear keypad and intercom repairs to land in these ranges:

• Linear AK-11 keypad replacement: $145 – $215 installed, parts and labor
• Keypad plus receiver (if the old format’s incompatible): $285 – $385 installed
• AE-500 or AE-2000 intercom board repair: $195 – $340 installed, depending on whether it’s a board-level fix or a full module swap
• Full entry station replacement (keypad + intercom + housing): $425 – $650 installed, depending on the series

The range exists because a straight keypad swap on a simple single-family gate is quick, while an intercom that’s been through a surge can require tracing wires, replacing the transformer, or re-pulling a section of two-conductor line. We quote the price in writing before any work starts, and our Kingswell Guarantee means if that repair fails inside 365 days, we come back and fix it at no charge. The parts we install carry the same written guarantee as the labor.

DIY or Call Us?

Here’s a realistic split. If your keypad is completely dead, check the breaker and the low-voltage transformer first. That’s a five-minute check and it costs nothing. If the keypad lights up but won’t open the gate, try reprogramming it using the instructions printed on the inside face of the keypad housing; Linear prints them right there for a reason.

What we’d hesitate on: wiring a new keypad directly into an operator you don’t fully understand. Linear keypads tie into gate control boards with low-voltage connections, but wire the wrong terminal and you can short the board, and then you’re replacing a $400 board instead of a $165 keypad. Same with intercom boards: the boards are sensitive to polarity, and a reversed wire takes them out. If you’re not comfortable reading a wiring diagram, that’s not a knock. It just means the smart money is calling someone who traces those wires every week. Call us at (325) 225-5440 and we’ll give you a straight answer about what you’re dealing with before we ever send a truck.
