Linear Access Control Installation Nationwide

Linear Access Control Installation: The Keller Owner’s Guide

Linear access control installation in Keller typically runs $350 to $800 installed, depending on the keypad model, whether we’re pulling new low-voltage wire, and how many entry points are tied into the system. We stock Linear-compatible keypads, receivers, and control boards on our trucks, so most replacements happen in a single visit. The usual discovery goes like this: the gate worked fine last night, this morning the keypad beeps but the gate won’t move, or it stopped accepting a code that’s worked for five years.

That moment is frustrating, and it’s almost never the gate itself. It’s the access control telling the gate what to do. The good news is that Linear systems are built simply enough that a failed part is usually identifiable in the first ten minutes of diagnosis. Victor Salinas grew up in Keller and has worked on enough Linear keypads and receivers that he can usually tell you what’s wrong from a short description over the phone before we even roll the truck.

Which Linear Models This Applies To

Linear built access control around a few core product families, and we stock parts for all of them. The most common in Keller driveways are the AK-11 and AK-21 keypads, the MegaCode and Multi-Code receiver sets, and the older AM-KP and AP-5 entry keypads. If your system uses a Linear AE-1000 or AE-2000 telephone entry unit at a small community or multi-home gate, we service those as well, though they’re less common on single driveways here.

Here’s a compatibility gotcha that catches a lot of Keller homeowners: a Linear keypad that says “MegaCode” on the face will not talk to an older Multi-Code receiver without a bridge, and vice versa. The easy way to tell what you have is to pull the keypad faceplate off and look at the label on the circuit board. The model number is printed in small type near the bottom edge. If it’s too faded to read, we match by counting the wiring terminals and noting whether it’s a 3-wire or a direct 3-terminal setup. For OEM versus aftermarket, we recommend genuine Linear parts when the system is still under any warranty or when it’s tied into a receiver. For older systems where Linear has discontinued the exact board, we keep quality aftermarket equivalents that match the voltage and relay specs precisely.

Signs Your Linear Access Control Installation Is Failing

• Keypad lights up but the gate won’t respond. This usually means the receiver lost its programming or the relay on the control board finally gave out. It’s one of the most common failures on Linear systems that are ten years or older, especially after a hard Texas thunderstorm.
• A code that worked for years suddenly stops working. The keypad itself is usually fine. This is typically a memory corruption issue in the receiver, or a button on the keypad has worn to the point where it reads as a different digit. We see this most often on keypads that sit in full afternoon sun on west-facing Keller driveways.
• The gate opens on its own or won’t close all the way. On Linear systems, this points to a failing relay that’s chattering, or moisture inside the board enclosure causing intermittent contact. It’s not a ghost and it’s not the gate motor. It’s the control board sending phantom signal.
• You have to press the keypad multiple times before it registers. The membrane contacts inside the keypad degrade over time, and once they go, they go. This is a wear item, not a programming issue. We replace the keypad and the problem disappears.
• The intercom or telephone entry unit rings but the buzzer doesn’t open the gate. On AE-series units, this is almost always a dead relay or a failed power supply inside the unit. The audio still works because that’s a separate circuit. The fix is a board replacement, not a full system rip-out.

Replacement Cost & What’s Included

In Keller, a straightforward Linear keypad replacement runs $350 to $450 installed. That’s the part, the labor, the programming, and testing. If we’re replacing a receiver or control board rather than the keypad, expect $400 to $550. A full access control system with a new keypad, new receiver, and fresh low-voltage wiring from the house to the gate typically lands between $600 and $800.

What drives the range is the wire. Homes in older Keller neighborhoods like Hidden Lakes or Marshall Ridge often have original 3-conductor wire that’s been underground for twenty or thirty years, and if it’s degraded or spliced poorly, we run new wire rather than band-aid a failing line. The price is always quoted and agreed before any work starts. You’ll know the number before we touch a single screw, and every part and labor hour is covered by our written 90-Day Done Right Promise. If it isn’t right, we come back and make it right. No paperwork, no arguing.

DIY or Call Us?

Access control work is low-voltage, which makes it safer than line-voltage electrical, but there is a real way to get hurt here. If the keypad or probe is mounted on the gate itself, the gate is still a moving structure. Reaching across it to test wiring while the operator is powered is how fingers get pinched and tools get thrown. Beyond the physical risk, the electrical risk is to your existing equipment: wiring a 12-volt keypad into a 24-volt receiver input will fry the board before you realize what happened.

What an owner can safely do is check the obvious: confirm the breaker to the gate operator isn’t tripped, make sure the keypad isn’t caked with dirt or spider webs, and verify the wire connections at the keypad aren’t visibly loose or corroded. If those all check out and the gate still won’t move, call us at (254) 330-8718. A phone call costs nothing, and we’ll help you figure out whether it’s a ten-minute swap or something deeper.
