Linear Access Control Installation Nationwide

Linear Access Control Installation: The San Antonio Owner’s Guide

Linear access control installation in San Antonio typically runs $450 – $1,150 installed, depending on whether we’re replacing an existing controller board, adding a new keypad, or wiring a full telephone entry system. We stock Linear-compatible parts on our trucks and can usually get a failed unit diagnosed and swapped same day. Most owners discover the problem when the gate stops responding to a keypad code, a remote quits working, or the entry system powers on but nothing actuates.

Here’s the common scenario we see across San Antonio: the gate opener itself is fine, but the access control module that tells it when to open has failed. That’s often a burned relay, a fried controller board after a storm, or a keypad that’s taken years of direct Texas sun and the membrane buttons have finally cracked. Our techs, led by Nico Alvarez, diagnose the exact failure and give you a written price before anything gets unbolted.

Which Linear Models This Applies To

Linear’s access control line spans older AP-5 and AE-1000 telephone entry systems, the AK-11 digital keypad, the AM-KP keypad, and the more recent MegaCode and Multi-Code receiver families. If you have a Linear gate opener like the LDO50, LS050, or a legacy Linear slide operator, chances are the access control side was either factory-installed or added later as a separate keypad or receiver board.

The compatibility gotcha we run into most often: Linear changed receiver protocols over the years. A MegaCode garage receiver won’t talk to an older Multi-Code remote, and a keypad from the AP-5 era won’t integrate with a newer controller without a protocol bridge. Before ordering anything, we match the part number printed on the circuit board or the model label inside the keypad housing. For gate openers specifically, we’re also factory-familiar with LiftMaster, Mighty Mule, and Ghost Controls, so if a Linear retrofit makes more sense than repairing an obsolete module, we can have that conversation honestly.

On OEM versus aftermarket: we install genuine Linear parts when the controller board, transformer, or keypad logic matters. For wear items like keypad membranes and antenna mounts, quality aftermarket equivalents from brands like North Shore Commercial and GTO work fine and often cost 20 – 30% less. We’ll show you the difference in writing before you decide.

Signs Your Linear Access Control Installation Is Failing

• Gate won’t respond to a keypad code, but remotes still work. This usually points to a dead keypad or a failed receiver channel on the access controller, not the gate opener itself. The keypad sends a signal, but nothing on the receiving end hears it.
• Intermittent opening after rain or humidity swings. San Antonio’s spring storms push moisture into old keypad seals and corroded terminal blocks. If the gate works fine on dry mornings and quits after an afternoon downpour, water intrusion is the likely culprit.
• Keypad buttons need to be pressed repeatedly or hard. The membrane switches wear out from UV exposure and repeated use. Once the tactile layer cracks, no amount of cleaning brings it back.
• Relay clicks inside the control board, but the gate doesn’t move. The access controller is doing its job, but the relay contacts have pitted or welded. This is repairable at the board level, but many older Linear boards are easier to replace entirely.
• Telephone entry system rings the house, but audio is static or one-way. On Linear AE-1000 and similar units, this is usually a failing power supply capacitor or a degraded telephone line interface board.

Replacement Cost & What’s Included

Here’s what we bill for access control installation in San Antonio:

• Diagnostic visit: $59, waived if you approve the repair on the spot.
• Keypad only (AK-11, AM-KP, or equivalent): $180 – $320 installed, including weather sealing.
• Receiver board or controller swap (AP-5, AE-1000 logic board): $350 – $650 installed, depending on board revision and availability.
• Full telephone entry system replacement: $800 – $1,150 installed, including wiring check and programming.

Every quote includes the part, labor, programming, and a written warranty. The price we show you before opening the toolbox is the exact price on the invoice when we finish. Nico’s rule stands: if the price isn’t in writing, it isn’t real. And every repair carries our 365-Day Done Right Promise: if the fix fails within 365 days, we return at no charge.

DIY or Call Us?

You can safely check a few things before calling: confirm the opener has power, verify the breaker is on, and test the keypad with a fresh set of codes in case one was accidentally reprogrammed. But access control wiring involves low-voltage logic lines and, on some Linear units, line-voltage transformers inside the same enclosure. A crossed wire on a controller board sends 120 volts where 12 volts belongs, and you’re replacing a $400 board instead of tightening a terminal.

If the issue is anything beyond a tripped breaker or a dead keypad battery, call us. We’ll text you a live arrival time, diagnose on site, and hand you a written quote before any work begins. Reach Calder Gate Repair San Antonio at (361) 314-4803.
