Linear Access Control Installation Nationwide

Linear Access Control Installation: The Houston Owner’s Guide

We stock and install Linear-compatible access control parts across Houston, and a full installation typically runs $450 – $1,100 parts and labor, with most jobs completed the same visit. When a Linear system quits, it’s usually the keypad, the receiver board, or the power supply that gave out, not the gate itself. Tell me what the gate is doing – or not doing – and I’ll give you a real number before I ever touch a wrench.

Most Houston owners discover the failure the annoying way: the keypad lights up but the gate won’t move, the remote works only from three feet away, or the whole system goes dead after a hard rain. Linear builds solid equipment, but Houston’s humidity, afternoon thunderstorms, and clay-heavy soil that shifts with every wet-dry cycle put real strain on low-voltage wiring and outdoor keypads. We’ve pulled apart Linear keypads in Sugar Land where the membrane buttons had corroded from condensation alone. The part number is still legible on the back; the fix is straightforward if you know what the gate is doing or not doing.

Which Linear Models This Applies To

This work covers the Linear access control systems most common on Houston residential and light-commercial gates: the AE-100, AE-500, and AE-1000 telephone entry units, the AK-11 and AK-21 digital keypads, the AM-KP keypad, the MGR and MGT gate receivers, and the APeX series controllers. If your property has an older Linear entry system from the early 2000s, we can still source parts or match a compatible replacement; Linear’s product line has shifted over the years, but many components interchange across generations if you know which revision you’re holding.

Here’s a compatibility gotcha most people don’t catch: Linear keypads and receivers operate on either 318 MHz or 310 MHz, and the frequency is stamped on the circuit board, not always on the outer housing. Buy the wrong frequency and the new part will power up fine and never talk to the gate. Also, Linear changed the mounting footprint on the AE series between older and newer production runs, so a drop-in replacement isn’t always drop-in. We check the board revision and mounting dimensions before we quote, so the part that shows up on the truck actually fits.

On OEM versus aftermarket: for control boards and receivers, we prefer genuine Linear or Linear-certified equivalents because the programming and frequency tolerances are tighter. For keypads and housings, a quality aftermarket unit often matches OEM specs at a better price, and we’ll tell you which is which before you spend a dollar.

Signs Your Linear Access Control Installation Is Failing

• Keypad beeps but the gate doesn’t move. The keypad is sending a signal, but the receiver board isn’t hearing it. This is usually a failed relay on the control board or a frequency drift in the receiver, both common after five to seven Houston summers.
• Remote range shrinks to a few feet. The receiver’s antenna or the remote’s battery is the easy suspect, but in Houston we often find moisture in the receiver housing has corroded the antenna connection. The receiver works; it’s just deaf.
• Whole system dead after a storm. Linear power supplies are sensitive to surges, and a nearby lightning strike or a transformer spike will take out the low-voltage side before you notice anything else. The keypad goes dark, the gate stays put, and the fix is a new power supply and a surge protector on the line.
• Keypad buttons need to be pressed hard or multiple times. The membrane button contacts wear and oxidize. Houston’s humidity accelerates this; a keypad that worked flawlessly in spring can get cranky by August.
• Gate opens randomly or won’t close. This is often a loop detector issue rather than the Linear unit itself, but when it’s the Linear controller’s relay sticking, the board is on its way out. We replace the board before the relay welds itself shut and leaves the gate standing open all night.

Replacement Cost & What’s Included

In Houston, Linear access control installation runs $450 – $1,100 installed, depending on which component failed and what’s already on the property.

• Keypad replacement (AK-11, AK-21, AM-KP): $250 – $450 installed
• Receiver board replacement (MGR, MGT): $300 – $550 installed
• Power supply replacement: $200 – $400 installed
• Full system upgrade to APeX controller matching existing wiring: $800 – $1,100 installed
• Keypad plus receiver replacement (common pairing): $450 – $700 installed

The price includes the part, the labor to remove the old component and wire in the new one, programming, and testing at the gate. You get the number in writing before any work starts, and it doesn’t change at the end. Every Linear access control installation we do in Houston carries the Kingswell Guarantee: written price, real arrival window, clean job site, and a written guarantee on the repair. If it fails within 365 days, we come back and fix it at no charge under the 365-Day Done Right Promise.

DIY or Call Us?

You can safely check a few things yourself before spending any money. Make sure the keypad is getting power (the backlight or beep confirms it). Check the gate’s manual release to confirm the gate itself moves freely. Look for obvious water inside the keypad or receiver housing. Those checks take five minutes and they tell us a lot.

Where DIY goes wrong is when the wiring comes out. Linear access control wiring is low-voltage, so you won’t get a dangerous shock, but a miswired relay or a crossed wire can smoke a brand-new control board in seconds. We’ve been called to enough Houston properties where a well-meaning weekend project turned a $300 keypad replacement into a $700 control board job. If the part you’re replacing involves anything beyond swapping a battery or tightening a terminal, call us at (325) 378-0676 and let a background-checked, uniformed technician handle it. The estimate is free, and the price is in writing before we touch anything.
