Linear Access Control Installation Nationwide

Linear Access Control Installation: The Fort Worth Owner’s Guide

Linear access control installation in Fort Worth typically runs between $425 and $1,600 installed, depending on whether you’re replacing a failed circuit board, adding a keypad, or upgrading to a full telephone-entry system. We stock Linear-compatible parts on our trucks and can usually diagnose and complete most access control repairs in a single visit. That matters because when your Linear keypad stops accepting codes or your gate won’t respond to the remote, every day it’s down is a day your driveway becomes a parking lot for anyone who notices.

Most Fort Worth homeowners don’t discover their access control has failed until they’re standing at the gate in the rain, punching in a code that worked yesterday. Sometimes it’s a dead keypad. Sometimes the gate operator hums but won’t move. Sometimes the system works fine for one code but not another, which means the board is failing rather than the wiring. The specific part matters a lot here, because Linear made several generations of access control equipment, and they don’t all talk to each other. We’ll get into that below.

Which Linear Models This Applies To

Linear made access control gear under several product families that we see regularly in Fort Worth neighborhoods: the AE series telephone entry systems (AE-100, AE-500, AE-1000), the AM-KP keypad line, and the APeX series controllers. The compatibility gotcha with Linear is that older AE systems used a proprietary communication protocol between the master board and slave units. Linear’s newer APeX boards won’t speak to older AE slave modules, and vice versa. You can’t mix generations on the same gate, which catches people who buy a replacement board online thinking one Linear board is as good as another.

To identify what you have, look for the model sticker on the inside of the cabinet or on the back of the keypad housing. The model number usually starts with the series letters, like AE-500-3 or APeX-I. If the sticker is gone, take a clear photo of the board itself before calling anyone. Linear boards have distinctive traces and chip layouts, and we can identify most of them from a photo. For Fort Worth homeowners, we generally recommend OEM Linear boards for the controller itself and quality aftermarket equivalents for things like power supplies and enclosures, where the aftermarket part is often built better than the original.

Signs Your Linear Access Control Installation Is Failing

• The keypad accepts some codes but rejects others. This almost always points to a failing memory chip on the control board rather than a keypad problem. The board forgets codes in blocks, not one at a time. We see this a lot on AE systems that are eight or more years old in the Fort Worth heat, because prolonged heat exposure degrades the board’s onboard storage.
• The gate operator clicks but won’t move. The access control board sends the open signal but the operator relay isn’t engaging. This can be a worn relay on the Linear board or a low-voltage problem at the operator. Cody Beckman usually tests this first thing on site, because swapping the board only fixes one of those two causes.
• The system works after rain, but not after a dry spell. This is a grounding issue. Fort Worth’s soil shifts between wet and dry cycles, and gate circuits on older installations lose ground continuity over time. The access control works intermittently because the ground path is being completed through moisture, not through the actual ground rod.
• The telephone entry system rings but you can’t open the gate. This is frequently a relay failure on the Linear board. The call path works, but the relay that closes the circuit to the gate operator has burned out. We replace the relay or the board depending on the board’s age and overall condition.
• The keypad lights up but nothing happens when you press buttons. The keypad’s membrane contacts are worn past their service life. On Linear keypads, this is typically a full keypad replacement rather than a repair, and it’s a part we keep on the truck for most common Linear models.

Replacement Cost & What’s Included

Here’s what Fort Worth homeowners can expect to pay for Linear access control installation work in 2025, based on the parts and labor we quote most often:

• Single keypad replacement (Linear AM-KP or similar): $180 – $420 installed
• AE series control board replacement: $350 – $750 installed
• Full telephone entry system upgrade (AE-1000 or APeX): $900 – $1,600 installed
• Relay or power supply replacement: $120 – $350 installed
• Diagnostic visit (applied toward repair if you proceed): $89 – $149

Every quote includes the part, the labor, the connectors, weather sealing, and thorough testing of both the access control and the gate operator together. You’ll see the full written price before we touch anything, and that price is what you pay unless we find something else wrong and you approve new work in writing first. The 365-Day Done Right Promise covers the labor and the part we install. If it fails within a year because of our work or a defective part we supplied, we come back and make it right, no argument and no service fee.

What drives cost up or down is mostly whether the system is a standalone keypad or a full telephone entry cabinet, and whether the old wiring can be reused. Some Fort Worth installs from the 2000s used unshielded wire that was adequate for single-gate setups but causes interference with newer boards. Rewiring a keypad takes about an hour of additional labor and a spool of shielded cable.

DIY or Call Us?

An access control panel is a low-voltage system, which means you don’t face the same shock risk you’d have with a main panel or a line-voltage operator. What you do face is the risk of miswiring the release relay or shorting the board with an incorrect power supply, and those mistakes turn a $200 repair into a $700 board replacement. If you want to check something yourself, start with a photo of the model sticker and a test of the operator’s manual release button. Those two steps tell you whether the operator itself functions, which narrows the problem to the access control.

Beyond that, we’d suggest letting us handle the board-level work. Linear boards have specific voltage tolerances, and they don’t forgive reverse-polarity wiring. One clip done in the wrong order and the board is dead. Fort Worth homeowners call us for this because it’s cheaper than buying a second board. If you’d like us to take a look, call (682) 841-5749 and describe what the gate is doing. Tell me what the gate is doing, and I’ll tell you what it needs, usually those are two different conversations.
