Linear Access Control Installation Nationwide

Linear Access Control Installation: The Boca Raton Owner’s Guide

Linear access control installation in Boca Raton typically runs between $425 and $1,150 installed, depending on whether we’re swapping a failed component into an existing Linear system or running a complete keypad, receiver, and lock circuit from scratch. Most repair-grade installs on an existing Linear operator are done in a single visit because we stock the common Linear receivers, keypads, and transformers on the truck. What we see most often in Boca Raton is a Linear access system that worked fine for years, then one morning the keypad lights up but the gate doesn’t move, or the remote stopped working while the keypad still opens the gate. The failure is usually in one specific component, not the whole system, and replacing that one part correctly is the difference between a $300 fix and a $1,500 unnecessary operator replacement.

Key takeaways:

• Most Linear access control failures in Boca Raton are single-component failures, not full system failures.
• We carry common Linear receivers, keypads, transformers, and wiring components on the truck for same-visit repair.
• Every install includes a written price before work starts and a photo record of what was found and what was replaced.

Which Linear Models This Applies To

Linear built access control around a handful of receiver and keypad lines that show up over and over on Boca Raton gates. The most common are the Linear MGR and MDR series receivers, the AK-11 and AK-21 keypads, and the EXA and AE series transmitters that pair to them. If your gate operator is a Linear LDO or LSO swing gate, an LD or SL slide gate, or one of the Linear PRO series units, the access control component is almost always a separate receiver that mounts on or near the operator. Identifying your exact part takes thirty seconds: the receiver has a model label on the back or side with a letter-and-number code like MGR-2 or MDR-U. The keypad usually has the model screen-printed on the front face below the buttons.

One compatibility gotcha we run into constantly in Boca Raton: Linear produced both 318 MHz and 310 MHz receivers depending on the series and production year. The transmitter and receiver must match frequency, and they won’t pair across frequencies. If someone hands you an old Linear remote and says “just make it work,” the first thing we check is frequency, not programming. The second thing we check is the transformer. Linear systems run on 12 or 24 VAC depending on the model, and a transformer that’s putting out 9 volts instead of 24 will light up the keypad but never trip the relay. That’s the difference between a failed board and a $40 transformer, and it’s the kind of thing that gets misdiagnosed when someone replaces parts instead of testing them.

On OEM versus aftermarket: we install genuine Linear parts when the customer wants them, but we also stock quality aftermarket receivers and keypads from third-party manufacturers that are frequency-matched and tested on Linear gates before they go on the truck. The honest answer is that a good aftermarket receiver often outlasts the original in Florida humidity, because the original Linear enclosures from fifteen years ago did not seal as well as the current production. We’ll quote both options in writing and let you pick.

Signs Your Linear Access Control Installation Is Failing

• Keypad lights up but the gate doesn’t move. The keypad is getting power, which means the transformer is working. The problem is usually the relay or the wiring from the receiver to the operator board. We’ve also seen corrosion in the keypad’s ribbon connector from years of Boca Raton salt air.
• Remote works sometimes, usually from closer than it used to. The receiver’s range is fading, which typically points to a failing antenna connection or a receiver module that’s losing sensitivity. Before replacing anything, we test with a fresh transmitter to rule out an old remote battery, but a shortened range on multiple remotes at once is almost always the receiver.
• Gate opens on its own or won’t respond to any transmitter, even freshly programmed ones. This is common after a lightning strike or a power surge, and Boca Raton gets both. The receiver board takes the hit and either locks in a relay-open state or stops decoding signals entirely. A new receiver module usually fixes it, and we’ll add surge suppression where the transformer feeds from the board.
• Keypad buttons are stiff, unresponsive, or only work when you press hard. The silicone membrane inside a Linear keypad breaks down from UV exposure and humidity. In a coastal city like Boca Raton, we see this earlier than inland installs. The fix is a new keypad face or full keypad unit, not a new gate system.
• You hear a click from the operator but the gate doesn’t move. The access control half of the system is working – the relay is firing. The failure is in the operator, the limit switch, or the motor capacitor. We test the relay output voltage at the board to prove the access control side is good before looking at the operator itself.

Replacement Cost & What’s Included

For Boca Raton homeowners, a Linear access control component replacement breaks down like this:

• Receiver module replacement (MGR, MDR, or aftermarket equivalent): $180 to $320 installed, including programming all remotes and testing the relay output.
• Keypad replacement (AK-11, AK-21, or aftermarket equivalent): $150 to $280 installed, including weatherproofing the wiring junction and programming codes.
• Transformer replacement: $80 to $140 installed, including voltage testing at the board and correcting any wiring that was damaged by the failed unit.
• Complete access control install (new receiver, keypad, wiring, surge suppression, documentation): $425 to $1,150 depending on wire run length, conduit condition, and whether we’re cutting into stucco or running wire through existing conduit.

Every one of those numbers is a flat price we write down and hand you before we start. That’s Haven Standard Clause 1. The price includes the part, the labor to install it, programming every remote and keypad on the system, testing the relay output at the board, and the photo record we leave behind. It doesn’t include hidden fees because we don’t have any. If the job needs something unexpected – rotted conduit, a shorted wire run, damage we find when we open the housing – we stop and quote the addition in writing before touching it. Our work on Linear access control systems is covered under the 365-Day Done Right Promise, and the parts themselves carry their manufacturer warranty, which we’ll register for you if the manufacturer requires it.

DIY or Call Us?

There are a few things an owner can safely check before calling us, and we encourage checking them because it helps us diagnose faster. Check the keypad for power – if the lights come on, the transformer is getting voltage to the keypad. Check the operator’s power switch and breaker. If you have more than one remote, test them all. If no remote works and the keypad is dead, check the transformer outlet or the blue transformer-looking box wired to the operator; that’s the low-voltage supply for the access control side. Those are all safe, non-invasive checks.

What we don’t recommend is opening the operator housing and probing terminals with a multimeter. The operator runs on 120 volts at the power terminals, and the board has capacitors that hold a charge after the breaker is off. We’ve seen enough fried boards and near-misses from well-meaning DIY work to say plainly: if the problem is inside the operator enclosure, that’s our job. Wiring a relay wrong costs more to fix than the original repair would have cost. If you’ve already done some poking around and the gate still isn’t working, call us at (754) 666-7602. Adrian Vance will put eyes on it, show you what’s failed, and hand you a written price before any work begins.
