Linear Keypad & Intercom Repair Nationwide

Linear Keypad & Intercom Repair: The Pasadena Owner’s Guide

We repair and replace Linear keypads and intercoms throughout Pasadena, typically for $185 to $430 installed, and we carry the common replacement parts on our trucks so most jobs are finished in a single visit. The usual story we hear from homeowners in Bungalow Heaven and Madison Heights is that the keypad still lights up but the gate won’t respond, or the intercom crackles so badly they can’t understand anyone at the curb. Sometimes it’s a slow fade: codes work intermittently for a few weeks, then stop altogether. Cole Rafferty has been fixing exactly these failures for years, and the honest truth is most Linear keypads and intercoms don’t need a full replacement, just the right part matched to the right model. Tell me what it’s doing wrong, and I’ll tell you exactly what it costs to fix it, before I touch a thing.

Which Linear Models This Applies To

Linear’s access control line spans several generations, and getting the right part depends on knowing which one you have. The older AP-3 and AP-4 keypads, common in Pasadena homes built in the 1990s and early 2000s, use a different wiring harness than the current AK-11 and AM-KP series. Swapping an AK-11 keypad onto a gate wired for an AP-3 won’t work without a wiring adapter, and even then the relay timing can be off. Same story on the intercom side: Linear’s AE-100 and AE-500 units are not interchangeable with the newer APE-series intercoms despite looking similar from the outside.

Here’s the fallback if you’re not sure what you have: open the keypad housing (two screws, no danger there) and look for a label on the circuit board. The model number is printed in small block letters, usually near the wire terminals. Photograph it before you call us, and we can tell you in one phone call whether you need an OEM Linear replacement or a quality aftermarket equivalent. For most Pasadena homes we lean OEM when the original part lasted a decade or more, but we stock both and we’ll give you an honest recommendation based on your model. A final compatibility gotcha: Linear changed the keypad faceplate dimensions between the AP-series and AK-series, so a board-only swap won’t always fit the old enclosure. We’ve seen a few Pasadena homeowners order a board online and end up with a part that won’t seat.

Signs Your Linear Keypad or Intercom Is Failing

• Dead keys or unresponsive digits: The keypad lights up but ignores presses. This usually means worn membrane contacts on the faceplate, not a full board failure. Faceplate replacements are one of the cheapest fixes we do.
• Intermittent code acceptance: The code works some mornings and fails others. In Pasadena’s dry heat, solder joints on older Linear boards crack microscopically over time, and temperature changes make the gap open and close. We can resolder or replace depending on severity.
• Intercom static, buzz, or one-way audio: Most often a failing electrolytic capacitor on the intercom’s power supply, not the speaker itself. Caps dry out after 10 to 15 years in our climate. A cap replacement usually restores clear audio.
• Gate opens but won’t close, or vice versa: If the gate motor itself works fine from the remote, the keypad’s relay contacts may be fused or pitted. We replace the relay, which is a $90 to $140 job on most Linear units.
• Water intrusion or corroded terminals: Pasadena’s rare but heavy winter rains expose weak gaskets. Corrosion on the terminal strip causes ghost signals and intermittent shorts. Cleaning helps short term; a new enclosure or board is usually the long-term fix.

Replacement Cost & What’s Included

Installed Linear keypad replacement in Pasadena runs $185 to $310 for the common AK-11 or similar single-gate keypads, including the part, wiring check, relay timing adjustment, and programming your existing codes back in. Intercom replacement or board repair runs $220 to $430 depending on the model and whether we’re replacing the board, the speaker, or the whole unit. The biggest variable is wire condition: homes in the Linda Vista and San Rafael hills have older gate wiring, and if we need to pull new low-voltage wire through a long run, that pushes the labor up. Every quote is written down and agreed to before we start work, with no surprise line items at the end. The replacement part itself carries its manufacturer warranty, and our labor is covered by the 365-Day Done Right Promise: if the repair isn’t right, we come back free.

DIY or Call Us?

Keypads and intercoms are low-voltage, so you’re not dealing with dangerous line current, but you are dealing with fragile electronics and gate controllers that cost hundreds to replace if a wrong wire lands in the wrong terminal. What a careful owner can do: photograph the model label, note exactly which buttons misbehave, and check for obvious corrosion on the terminals. What we’d rather you not attempt: splicing a new keypad to an older Linear controller with mismatched wire colors, because the relay wires are not standardized across generations. One crossed wire can smoke a gate controller, and suddenly a $200 keypad job becomes a $600 board replacement. Also, the keypad talks to the gate motor through the controller’s logic board; if the motor is also misbehaving, the keypad isn’t the real problem. That’s exactly the diagnostic step we do before quoting anything. If you’re in Pasadena and would rather not guess, call us at (626) 657-5425 and we’ll tell you what we think over the phone, free.

FAQs

How long does a Linear keypad last in Pasadena? In Pasadena’s climate, a well-installed Linear keypad lasts 7 to 14 years depending on sun exposure. Units on west-facing gates in the hills degrade faster: the UV beats up the membrane, and the summer heat ages the capacitors. South-facing keypads under an overhang often outlast the gate motor itself.

Can you repair my existing Linear keypad instead of replacing it? Yes, and we prefer that. Keypad faceplates, relays, and power supplies are all replaceable components. We only recommend a full replacement when the board itself has failed or the enclosure has water damage beyond a gasket swap. We’ll show you the board and explain why before any money changes hands.

How long does a keypad or intercom replacement take? In most Pasadena locations, a keypad swap takes 45 to 90 minutes and an intercom board replacement takes about an hour, assuming the existing wiring is intact. If we need to pull new wire for an older property, add another hour or two. We carry the common Linear parts on the truck, so most jobs are one visit.

Do you stock Linear keypad and intercom parts on the truck? We stock AK-11 keypads, common faceplates, relays, power supply caps, and intercom boards for the most common Linear models on our Pasadena service vehicles. Less common AE-series intercom parts we order and install within the week. We also keep parts for LiftMaster, Mighty Mule, and Ghost Controls gates, and we’re factory-trained on all of them. Call (626) 657-5425 and we’ll confirm whether your part is on the truck before we schedule.
