We install, repair, and replace FAAC access control systems across San Antonio, and we stock the parts most likely to fail on a Texas fence or gate. A typical FAAC access control installation in San Antonio runs between $450 and $1,200 installed, depending on whether we’re replacing a keypad, adding a card reader, or wiring in a full telephone-entry setup. Most owners discover they need this work when the keypad stops responding, the card reader quits mid-cycle, or the gate starts opening on its own because a relay welded shut.
We carry FAAC-compatible keypads, card readers, antenna modules, and control boards on our service trucks, which means we can usually handle an access control repair or installation the same day we diagnose it in San Antonio. You’ll get a written price before we touch anything.
Which FAAC Models This Applies To
FAAC builds access control panels and accessories for nearly every gate opener they’ve sold in the last two decades, but the parts aren’t one-size-fits-all. The 455 D, 400, 412, 770, E024U, and C721 control boards each have their own access control wiring points and compatibility requirements. The gotcha most San Antonio owners run into: an older FAAC 400 board won’t accept a newer FAAC keypad without a small adapter module, and if someone wires the keypad directly to the wrong terminals, you’ll burn out the input circuit on the board itself. That’s a $300 mistake waiting to happen.
We match the access control component to the exact FAAC board revision you have. If the board label is faded or missing, we read the component layout and connector count to identify it, because FAAC made silent revisions to the same model numbers over the years. On OEM versus aftermarket: for control boards and radio modules, we recommend FAAC original parts. For keypads and card readers, quality aftermarket equivalents from brands we’ve vetted match the OEM spec at 30 to 40 percent less, and we’ll show you both options before you choose.
Styles & brands we work with
Signs Your FAAC Access Control Installation Is Failing
- Keypad accepts the code but the gate doesn’t move. The relay on the access control output is usually the culprit. It clicked for years until the internal contacts pitted and stopped conducting. We replace the relay or the keypad module itself.
- Gate opens or closes on its own, no one around. A failing antenna module or a shorted keypad wire can send phantom signals to the board. We’ve seen this on San Antonio gates near FM radio towers and high-voltage lines, where stray RF interference walks the gate open.
- Card reader beeps but won’t release the gate. The reader itself may be fine while the connection to the board has corroded. San Antonio humidity plus afternoon heat ages wiring insulation fast, especially on west-facing gates in neighborhoods like Alamo Ranch or Stone Oak.
- Telephone entry unit calls but won’t open the gate when you press 9. The DTMF decoder on the telephone entry board drifts out of spec over time. It’s repairable on some FAAC units, but if the board is over eight years old, replacement is usually cheaper.
- Backlit keypad works sometimes, dead other times. Intermittent power to the keypad usually means a failing power supply on the main board, not a bad keypad. We test voltage at the keypad leads before selling you a new one.
Replacement Cost & What’s Included
For most FAAC access control installations in San Antonio, expect $450 to $1,200 installed. A basic keypad or card reader swap lands between $450 and $650 including the part and labor. A full telephone entry unit with programming runs $700 to $1,200. A control board replacement adds $300 to $600, depending on the FAAC model.
Every quote we write includes the part, the labor to install and test it, programming of codes or cards, and cleanup of the old wiring. You’ll see the part cost and the labor broken out separately. The number we write down is the number you pay. If we open the unit and find additional damage, we stop, call you, and send a revised price before proceeding. No surprises at the invoice.
We also stock parts for LiftMaster, Mighty Mule, and Ghost Controls systems, so if you have a mixed setup on your property, one visit covers it.

You can safely check the basics: confirm the keypad lights up, verify the gate still opens with the manual button or remote, and check that no visible wires are chewed through near the hinge posts. Those checks cost you nothing and help us diagnose faster over the phone.
Beyond that, this is low-voltage electrical work tied directly to a motor board, and the wrong connection can fry a $400 control board. FAAC boards are not forgiving of wiring mistakes. If you’re not certain about the board revision, the wire order, or whether the power supply is functioning, call us at (361) 314-4803. We’ll come out, identify the failure, and send you a written price before we open the toolbox.
FAQs
A keypad or card reader swap takes 45 to 90 minutes on site, including programming. A full telephone entry installation takes two to three hours. We quote the time before we start. Call (361) 314-4803 for a free estimate.
Yes, in many cases a failed relay, loose antenna wire, or drifted decoder can be repaired for less than a replacement unit, and we’ll tell you honestly when repair is the better call. If the repair won’t hold up for at least a year, we recommend replacement instead. Call (361) 314-4803 and we’ll give you a straight answer.
Keypads and card readers typically last 5 to 8 years in San Antonio’s heat and humidity before buttons or circuit traces fail. Control boards last 8 to 12 years if the gate operator is maintained and the wiring isn’t exposed to standing water. Units on west-facing walls fail faster from UV and thermal cycling.
We keep the most common FAAC keypads, card readers, relays, and antenna modules on our service vehicles, so we can usually install the same day we diagnose the problem in San Antonio. If your unit needs a less common board revision, we order it and schedule return installation within a few days.
