Linear Keypad & Intercom Repair: The Laguna Hills Owner’s Guide
We repair and replace Linear keypads and intercom systems on driveway gates throughout Laguna Hills, with most jobs completed the same visit and most replacements installed for between $285 and $520, parts and labor included. That price is quoted and agreed before we turn a single screw. The typical call starts the same way: the keypad works some mornings, not others, or the intercom rings but no voice comes through, and one day it simply stops responding altogether.

If your Linear keypad is not accepting the code, or the intercom crackles but won’t release the gate, you’re dealing with a part that handles weather, wear, and voltage every single day. Here’s what we’ve learned fixing hundreds of them in Laguna Hills and southern Orange County.
Which Linear Models This Applies To
We carry parts and repair know-how for the Linear AK-11, AK-21, AK-31, and AM-KP keypads, along with the older MC-series keypads still common on gates installed in the 1990s and early 2000s. On the intercom side, we service the Linear AE-100, AE-500, and AE-2000 telephone entry systems, plus the MGT and ACP series gate operator control boards that connect to them. This is important: Linear intercoms are not one-size-fits-all. An AE-100 keypad will not talk to an AE-2000 board without the correct interface wiring, and an AM-KP wired for 12V will fail fast on a 24V system. That’s the kind of mismatch we catch before a new part gets burned up.
We’re an independent service company, not affiliated with Linear. That means when an OEM part is backordered or priced like it’s made of aerospace material, we can offer a quality aftermarket equivalent that fits, seats correctly, and carries our same 90-Day Done Right Promise. The decision is yours, and we’ll lay out both options with honest numbers before ordering anything.
Signs Your Linear Keypad or Intercom Is Failing
- Keypad works only when pressed hard or at an angle. The membrane or individual buttons are worn. Linear keypads use a carbon-contact pad under the membrane, and once that contact starts to flatten, the code entry gets unreliable no matter how carefully you type it.
- The gate opens on its own or won’t close after a code entry. Moisture intrusion is the usual culprit. The gasket at the keypad edge dries out under the Laguna Hills sun, cracks, and lets ocean-tinged morning air into the board. Corrosion follows within a season.
- The intercom rings but no voice (or only static) comes through. Usually a failed speaker or mic element, but we also find corroded terminal strips where the intercom wire enters the master box. The wire itself sometimes tests fine and the termination is the problem.
- The visitor calls, you press 9 to open, and nothing happens. That’s either a relay stuck on the intercom board or a broken connection between the intercom and the gate operator. We’ll check both sides before we quote a board replacement, because replacing a board in the field when the problem was a $6 relay costs you money you shouldn’t spend.
- The display is dim or the keypad lights flicker. Low voltage at the keypad, usually from a tired transformer or a wire splice that’s failing underground. Linear keypads are rated for a specific voltage window, and anything outside it shortens their life fast.
Replacement Cost & What’s Included
A Linear keypad replacement in Laguna Hills typically runs $285 to $420 installed, depending on the model and whether we’re doing a simple swap or replacing the housing, gasket, and mounting plate. Intercom systems run higher: $380 to $520 for a direct Linear intercom replacement, and if a new control board is required, that’s additional and always quoted before we start. The price you’re quoted is the price you pay. Parts, labor, wiring, programming, and testing are included in the number we give you at the beginning.
What drives the range is straightforward. A surface-mounted AK-11 on a well-maintained pedestal is a twenty-minute job. An AE-2000 in a sun-baked enclosure with degraded wire and a suspect transformer might take us an hour and a half to do right. Either way, the work is covered by our 90-Day Done Right Promise, in writing: if it’s not right, we come back and make it right at no charge.

DIY or Call Us?
Here’s our honest split. You can safely check a few things before calling: make sure the breaker for the gate circuit hasn’t tripped, confirm the keypad doesn’t have visible cracks where water could enter, and try a second code if you’ve programmed one. That’s about where we’d stop. Linear keypads operate at low voltage, so the shock risk is minimal compared to a gate motor or the primary electrical run. But the diagnostic risk is real: a miswired keypad or intercom can take out the gate operator board, and those are far more expensive than the keypad itself. If the LED lights don’t illuminate at all, or the intercom keypad buttons are dead, call us at (213) 587-4828 and we’ll come see it in person.
We’d rather tell you a part is fine and tighten two terminals than sell you a keypad you didn’t need. Our technicians do both tests in one visit, so you get a straight answer either way.
FAQs
In our experience, Linear keypads here last 5 to 8 years before the membrane or gasket fails, and intercom boards typically last 8 to 12 years. The coastal humidity and intense sun exposure in Laguna Hills shorten those lifespans compared to inland installs, which is why we replace a lot of gaskets before the board itself fails.
Sometimes. A sticky button or cracked gasket can be replaced if we have the part on the truck, and wiring or terminal corrosion can be cleaned and re-terminated. But once the board itself is corroded or the membrane is torn, the repair cost approaches replacement cost, and we’ll tell you that straight.
Most Linear keypad replacements take under an hour on site, including programming and testing. Intercom replacements usually run 60 to 90 minutes depending on wiring condition and whether the existing enclosure can be reused.
We stock common Linear keypads, gaskets, and replacement boards on our service vehicles, including parts that also work with LiftMaster, Mighty Mule, and Ghost Controls systems. If the exact part for your model isn’t on the truck, we order it and return for installation once it’s in. Call (213) 587-4828 for a free estimate, and we’ll let you know before the first visit what we expect to find.
