Linear Keypad & Intercom Repair Nationwide

Linear Keypad & Intercom Repair: The North Hollywood Owner’s Guide

Most Linear keypad and intercom failures in North Hollywood come down to three things: a worn keypad membrane, corroded wiring terminals, or a power supply that’s quietly dying. We stock Linear-compatible keypads, intercom modules, and power supplies on our trucks, and most repairs run between $180 and $420 installed, depending on the model and whether we’re replacing the keypad alone or the full intercom station. Same-day service is usually available when you call before noon.

What you’ll usually notice first is an intercom that works when it wants to, a keypad where one or two numbers stopped registering, or a call button that buzzes but never rings the house. By the time a Linear keypad reaches that point in North Hollywood, the cause is rarely mysterious, but it usually is specific. Adrian Vance has opened enough of these to tell you the difference between a $12 wire repair and a $400 board swap in the first ten minutes on site.

Which Linear Models This Applies To

Linear built a lot of keypads and intercoms under different names, and not all of them play nicely with each other. The AK-11, AK-11A, and AK-21 are the most common exterior keypads we see on North Hollywood driveways, and the AE-100, AE-2000, and AE-500 are the telephone-entry and intercom systems that show up on the gate side. The AK-11 and AK-21 share a housing but not a wiring pattern, so a keypad that looks right on the outside can still be wrong on the inside.

One compatibility gotcha worth knowing: the AK-11 series expects a 24-volt DC supply, while the older AK-11 Exterior model shipped configured for 12-volt systems. Wire a 24-volt transformer to a 12-volt board and the keypad lights up for about two days before it quits. We see that after a previous repair more often than we should.

If the label is faded, check the back of the keypad or the inside of the case for a stamped model number. When there’s no label at all, photograph the keypad and the gate control board and text them to us before the visit. It saves a trip when the part turns out to be a clone rather than a genuine Linear. For OEM versus aftermarket: genuine Linear keypads from Nortek are well made, but the aftermarket AK-11 equivalents we stock for Vance Gate Repair North Hollywood are built to the same footprint with sealed membranes that hold up better in direct sun. In North Hollywood, where a west-facing keypad bakes for six hours a day in summer, the membrane is the first thing to fail, and the aftermarket versions use a thicker overlay.

Signs Your Linear Keypad & Intercom Repair Is Failing

• One or two keys stopped responding. The membrane contacts under the button wear through first on numbers people actually use, and once one digit goes, the whole code is useless. We usually replace the keypad rather than trying to rebuild a membrane.
• Intermittent ring or call failure at the house. Corrosion on the intercom’s screw terminals or a failing power supply can look exactly the same. A meter reading at the station tells us which one it is in about five minutes.
• Keypad beeps but the gate won’t move. This points to the relay output on the keypad or a dead input on the gate control board. If the keypad’s relay clicks and the gate still doesn’t respond, the keypad is fine and the problem is further down the line.
• Intercom works one direction only. One-way audio on Linear AE-series intercoms usually means a dead speaker or a broken wire in the conduit, not a board failure.
• Display blank or flickering. A flaky 12-volt or 24-volt transformer is the suspect more often than the intercom board itself. We check supply voltage before quoting a board replacement, because in North Hollywood a $40 transformer is still $40.

Replacement Cost & What’s Included

Installed Linear keypad replacement in North Hollywood runs $180 to $320 for most AK-series models, and full intercom or telephone-entry replacement runs $280 to $420 depending on the system and whether we’re reusing the existing wiring. The written price you get before we start includes the part, labor, new terminals or connectors where the old ones are corroded, and a photo log of what was found and installed.

• AK-21 keypad replacement: $220-$320 installed
• AE-100 intercom module replacement: $280-$380 installed
• Telephone-entry board replacement: $320-$420 installed

DIY or Call Us?

There are two things you can safely check on your own. First, confirm the keypad has power: if no beep at all, the transformer may be dead, which is a $50 fix, not a $300 one. Second, check the wire connections behind the keypad faceplate. If a wire has pulled loose, you’ve found the problem.

Beyond that, this work involves wiring that may be live and components matched to a specific voltage, and a wrong guess can damage the control board. We don’t say that to scare you out of a simple fix; we say it because we’ve replaced boards that died from a miswired transformer in North Hollywood. If the keypad is beeping weird or the intercom is half-working, call us at (213) 566-1045 and we’ll sort it out on the first visit. A free estimate comes with every call.
