Linear access control installation in West Covina typically runs $850 to $2,400 installed, depending on whether we’re adding a standalone keypad, a telephone entry system, or a full card-reader setup tied into an existing gate operator. Most jobs take one visit, and we carry Linear-compatible keypads, receivers, and controllers on the truck so we’re not sending you back to a supply house. The way most West Covina homeowners discover this problem: the gate stops responding to the remote that worked yesterday, or the keypad lights up but won’t trip the operator.

What we usually find is a failed receiver board, a keypad with corroded contacts, or an access controller that lost its programming after a power surge. The gate motor itself is often fine. Linear systems are sturdy, but the access control side takes the daily abuse: sun, rain, the occasional sprinkler overspray, and a lot of button presses.
Which Linear Models This Applies To
We work on the full Linear access control line: the AE-100, AE-500, and AE-2000 telephone entry systems, the AM3Plus and APeX series operators with built-in receivers, and the MEGACODE and multi-code receivers paired with older swing and slide gates. The compatibility gotcha most owners miss: a Linear APeX operator uses a different receiver frequency than the older MEGACODE systems. If you buy a keypad or remote that doesn’t match your receiver’s frequency, it simply won’t pair, no matter how many times you follow the programming steps.
For Linear specifically, we stock OEM boards and controllers when the job calls for them, but we also carry quality aftermarket equivalents for the common failure points: receiver logic boards, power supplies, and keypads. The honest trade-off is this: OEM Linear parts cost 30 to 50 percent more but come with the manufacturer’s exact firmware and connector layout. A good aftermarket board works, but it may not support every feature of the original, like call-forwarding on a telephone entry system. We’ll tell you which one makes sense for your gate before we order or install anything.
To identify your Linear part, look for the model label inside the operator housing or on the back of the keypad. The label will show the series (AE-, APeX, AM3Plus) and a frequency code if it’s a wireless receiver. That frequency is the number that matters for pairing.

Signs Your Linear Access Control Installation Is Failing
- The gate opens sometimes, but not every time. This is the classic failing receiver symptom. A worn relay on the receiver board makes intermittent contact, so the signal gets through on some presses and dies on others. It tends to get worse over a few weeks.
- The keypad beeps but won’t open the gate. The keypad is sending a code, but the controller isn’t accepting it. Often this is a programming loss after a power blip, but we also see it when the keypad’s output wire has corroded inside the conduit, especially on older West Covina homes where the original wiring wasn’t sealed well.
- Your remote works, but the visitor keypad doesn’t. Two separate receivers or a split controller board. In Linear systems, the remote receiver and the keypad can be on different boards. One can be dead while the other works fine.
- The gate opens on its own, or stays open after a close command. A stuck relay on the access controller can send phantom open signals. This is more than annoying; it’s a security problem on a property where the gate exists to keep people out.
- You hear a click but the operator doesn’t start. The access control is triggering, but the operator isn’t receiving the signal. Usually a bad connection at the terminal block or a failed low-voltage transformer. We check the whole chain, not just the part that’s obviously dead.

AfterReplacement Cost & What’s Included
Here’s what Linear access control installation costs in West Covina, with typical ranges we quote before the job:
- Standalone keypad or card reader (replace failed unit): $450 – $850 installed
- Receiver board replacement on existing operator: $400 – $750 installed
- New telephone entry system (AE-100 or equivalent): $1,100 – $1,800 installed
- Full access control package with controller, keypad, and two remotes: $1,400 – $2,400 installed
Every one of those numbers is a written price delivered before we start work. The range depends mostly on two things: the Linear model you have, and the condition of the existing wiring and conduit. Older installations with corroded connectors take longer, and we won’t reuse wiring that’s past its useful life. The written quote covers parts, labor, programming, and cleanup. The repair is covered by our 365-Day Done Right Promise: if it fails within a year, we come back and fix it at no charge. That’s not a policy we advertise on a decal; it’s in writing on every invoice.
DIY or Call Us?
There are a few things an owner can safely check before calling: confirm the operator has power, look for a tripped GFCI or breaker, and check whether the keypad’s display lights up. If the keypad is dead and the breaker is fine, that’s not something to open up and probe yourself. Linear access control boards run on low voltage, but the operator itself carries line voltage, and opening that housing without isolating power is how people get hurt. The wiring between a telephone entry system and an operator also involves relay logic that’s easy to miswire if you’re not looking at the right schematic.
The gate either works right or it doesn’t, there’s not much in between. If you’ve done the basic checks and it still isn’t responding, call (925) 268-7956. We’ll diagnose the failure on site, show you the failed part, and hand you a written price before anything gets replaced.
FAQs
Most Linear keypads, receivers, and controllers last 8 to 12 years in this climate before something fails. The sun and the occasional wet winter are harder on outdoor keypads than the electronics inside a covered operator housing. Keypads mounted on the sunny side of a West Covina yard tend to age faster than shaded ones.
Sometimes. We can rebuild certain receiver boards with bad relays or capacitors if the board is otherwise sound. But when a board has corrosion across the traces or a failed processor, replacement is the honest fix. We’ll show you the board and explain what we’re seeing before we recommend either path. Call (925) 268-7956 to have us look at it.
Most standalone keypad or receiver swaps take 60 to 90 minutes on site. A full telephone entry system install runs 2 to 3 hours, including programming and testing. If we find wiring problems inside conduit, that can add time, but we’ll tell you before we proceed.
Yes. We carry Linear-compatible keypads, receivers, relays, and controller boards for the most common models, plus parts for LiftMaster, Mighty Mule, and Ghost Controls systems. If your part isn’t on the truck, we can usually have it within one business day.
If your Linear gate access isn’t doing what it should, call (925) 268-7956. A real person answers, and we’ll get your gate back to working right.
