We repair and replace Linear keypads and intercom systems across West Covina, typically for $220 to $480 installed depending on the model and wiring involved. Most keypad and intercom repairs are completed the same visit because we stock Linear-compatible parts on the truck. You’ll usually notice the failure when the keypad stops accepting your code, the intercom audio goes scratchy or silent, or the gate simply won’t respond from one side of the property even though remotes still work fine.

What surprises most West Covina homeowners is how often the keypad isn’t actually the problem. The wiring between the keypad and the operator takes the beating, especially on gates that face afternoon sun or sit near sprinkler heads. We diagnose the whole circuit before we sell you a part. Lonnie Burke has been correcting misdiagnosed keypad issues across the San Gabriel Valley for over a decade, and the fastest fix is usually the one that starts with an honest check.
Which Linear Models This Applies To
We service the full range of Linear keypads and intercoms, including the AK-11, AK-21, AK-31, and AP-5 series keypads, plus the AE-1000, AE-2000, and RE-2 intercom and telephone entry units. If you have a Linear gate operator like the LDO50, LSO50, or the older LRA series, the keypad compatibility is usually straightforward, but there is one gotcha worth knowing: Linear changed wiring conventions between older and newer production runs. A keypad wired to a 2005 Linear board may not be a direct swap onto a 2015 board without re-terminating the connectors. That detail gets missed by generalist technicians and it causes repeat failures.
For OEM versus aftermarket, our position is simple. On keypads, a genuine Linear replacement is usually worth the extra $40 to $60 because the weather sealing and keypad membrane hold up better in Southern California heat. On intercoms, the opposite is sometimes true. A quality aftermarket speaker or microphone module can match OEM performance at a better price, and we have installed enough of both to know which specific modules fail early. We will tell you which way we would spend our own money.
Carver Gate Repair West Covina is an independent service provider and not affiliated with Linear. We also stock parts for LiftMaster, Mighty Mule, and Ghost Controls systems, so if your property has mixed-brand equipment, one visit covers it.

Signs Your Linear Keypad & Intercom Repair Is Failing
- Code accepted but no gate movement. The keypad itself is often fine; the relay output or wiring to the operator has failed. We test the relay with a meter before replacing anything.
- Buttons need hard presses or multiple attempts. The membrane or tactile switches are worn. This is the most common failure on AK-series keypads after five or six years of direct sun, and it is a replace-the-keypad situation, not a clean-it-and-hope situation.
- Intercom audio buzzes or cuts out on one side. Typically a corroded connection or a failing speaker module. West Covina’s morning marine layer plus afternoon heat cycles accelerate corrosion at terminal blocks.
- Gate opens from the house intercom but not the visitor station, or vice versa. This points to a wiring fault between stations rather than the intercom hardware itself. We trace the line and repair the break instead of guessing.
- Keypad works intermittently after rain. Water is getting into the housing. The fix is not just a new keypad; the mounting surface and gasket need attention or you will replace it again next wet season.

DIY or Call Us?
Here is the honest split. You can safely check three things before calling: confirm the keypad is getting power by checking if any backlight or LED responds, verify the breaker for the gate operator has not tripped, and visually inspect the keypad housing for cracks or water intrusion. Those checks cost you nothing and help us narrow the problem faster.
What you should not do is open a live keypad or intercom housing and start probing wires. Linear equipment runs on low voltage, but there is still a transformer upstream connected to line voltage, and a short across the wrong terminals can fry the operator board. That turns a $240 keypad job into a $600 board replacement. We have seen it happen in West Covina more than once. If the simple checks do not solve it, call us at (925) 268-7956 and we will be out with the right parts.
FAQs
Expect five to eight years from a Linear keypad in West Covina’s climate before the membrane or buttons degrade. South-facing keypads with no shade can fail in four because direct afternoon sun bakes the plastic and dries out the internal switch contacts. A shaded or north-facing keypad often lasts at the upper end or longer. Intercom modules follow a similar pattern, with corrosion from moisture being the bigger variable. Call (925) 268-7956 if yours is acting up and we will tell you honestly whether it is worth repairing or replacing.
In most cases, a failing Linear keypad is replaced rather than repaired. The membrane and switch assembly is sealed at the factory, and opening it compromises the weather seal. Where repair does make sense is on wiring, connectors, and mounting surfaces. Those we can repair cleanly and warrant the work. Call (925) 268-7956 and we will tell you which category your keypad falls into before you spend anything.
Most single-keypad replacements take 45 to 75 minutes from arrival to test. Intercom module swaps run 60 to 90 minutes. A full telephone entry system replacement can take two to three hours, depending on how much of the existing wiring can be reused. We test the entire access cycle before we leave, including every code and both audio paths on intercom jobs.
Yes. Our West Covina trucks carry AK-series keypads, common intercom modules, wire, connectors, and relays so most repairs are completed the same visit. For less common Linear models, we source the part usually within one to two business days. Call (925) 268-7956 with your model number and we will tell you before we arrive whether we already have what you need.
If your Linear keypad or intercom is giving you trouble in West Covina, call us at (925) 268-7956. We will give you a written price before any work starts. The gate either works right or it doesn’t, and we make sure it does.
