We stock and install Linear access control systems across San Diego, with most installations running $450 – $1,150 depending on the keypad, reader, or intercom model and whether we’re upgrading an existing opener or adding standalone access. We keep the most common Linear entry components on our trucks, so a failed keypad or dead reader usually gets replaced same-day in most San Diego neighborhoods. The call usually starts the same way: a homeowner punches their code, nothing beeps, and now they’re either late for work or locked out of their own driveway. That moment is exactly why we carry Linear parts ready to go.

Here’s what matters before you spend a dime: you need the right Linear part for your specific opener and the right wiring setup for San Diego’s coastal air. Get either one wrong and you’ll be replacing the same component again in eighteen months. This page tells you what to look for, what it costs, and when to stop guessing and call us.
Which Linear Models This Applies To
Linear access control installation covers three main component types: the digital keypads (like the older AK-11 and the newer AM-KP series), the telephone entry systems (AE-100, AE-500, and the still-common AE-2000), and the radio receivers that sit inside or beside your opener and talk to remotes and keypads. Most San Diego homes built between 1998 and 2012 have Linear openers paired with an AK-11 keypad, which is now discontinued but still serviceable with aftermarket match parts that fit the original housing.
Identifying your exact part matters more with Linear than most brands. Flip the keypad faceplate or open the receiver box and look for the model number printed on the circuit board, not just the housing. Linear reused the same plastic enclosures across multiple board revisions, and the internal connectors changed between versions. A homeowner at a house in Clairemont showed us a keypad labeled AK-11 that actually had a later AM-KP board inside from a prior repair. That kind of mismatch is common, and it’s the first thing we check before quoting anything.
On the OEM versus aftermarket question: for Linear receivers and keypads, we typically recommend OEM Linear boards when available because the frequency matching (318 MHz on most Linear residential gear) is tighter from the factory. Quality aftermarket shells and faceplates are fine, but the electronics inside are where we prefer genuine Linear. We’ll walk you through the tradeoff in plain terms before any work starts.
Styles & brands we work with





Signs Your Linear Access Control Installation Is Failing
- Keypad beeps but gate doesn’t move. The keypad’s transmitter still sends a signal, but the receiver board inside the opener is no longer decoding it. We see this most often on Linear units that have lived through several wet winters in coastal areas like Ocean Beach or Point Loma, where salt air corrodes the receiver’s edge connector.
- One or two buttons stop responding. The keypad membrane has worn through on the keys used most. It’s always the same two buttons for most homeowners: the one you press at 6:40 a.m. and the one your teenagers mash. We replace the membrane or the entire board depending on which Linear series you have.
- Gate opens on its own or after a delay. This is usually a failing relay on the access control board sending a phantom trigger to the opener. On Linear telephone entry units, the relay contact points oxidize over time, especially in the marine layer that rolls through Mission Valley and up into Tierrasanta.
- Call box rings but audio is dead or crackling. The microphone or speaker on an older AE-series entry panel has corroded from moisture. You can hear the visitor trying to talk, but the signal is too degraded. We swap in a new audio module rather than replacing the whole access panel when the board is still good.
- Multiple remotes and the keypad fail at once. This points to the receiver, not the transmitters. The onboard Linear receiver has a capacitor that fails with age, and when it goes, every wireless device stops working the same day. Homeowners in Rancho Bernardo and Poway call us more often for this in summer, when heat accelerates capacitor wear on electronics mounted in metal enclosures that bake in direct sun.

AfterReplacement Cost & What’s Included
In San Diego, expect to pay $450 – $750 installed for a Linear keypad replacement, $650 – $1,150 for a telephone entry or access control panel replacement, and $250 – $400 if we’re just swapping a receiver or adding a second receiver to an existing Linear opener. These are installed prices for residential work, including the part, labor, programming, and testing. Commercial jobs in places like Kearny Mesa or Sorrento Valley run higher because we’re usually integrating with existing access infrastructure.
What drives the range is simple: the specific Linear model you have, whether we need to run new low-voltage wire from the panel to the opener, and whether the old wiring is salvageable. Sun-baked, brittle wire jacket is common in San Diego’s inland neighborhoods, and sometimes the fastest fix is a new wire run rather than chasing a short inside forty feet of degraded insulation.
Every quote is a written price before work begins. You’ll see the part cost, the labor, and the total, and that total is what you pay. This isn’t optional at Calder Gate Repair, it’s how we operate. If the repair fails within 365 days, we come back at no charge under our 365-Day Done Right Promise, and we’ll show you the failed part on the first visit so you’re never taking our word for it blind.
DIY or Call Us?
You can safely do a few checks yourself before calling. Confirm the keypad is getting power, check that the gate opener itself still works from the manual controls, and look for any obvious water intrusion or antenna damage on the access panel. Those observations help us diagnose faster when you describe them on the phone.
But access control installation on a Linear system means low-voltage wiring and sometimes line-voltage connections, and that’s where we recommend stopping. A miswired relay can fry the opener’s logic board, and a poorly sealed outdoor splice will fail again inside a year thanks to San Diego’s coastal moisture. That second failure is the expensive one, because now you’re paying for an access panel and a logic board. We also need to program the new component to your opener, which requires knowing the Linear-specific programming sequence for the receiver’s learn mode. Nico Alvarez has handled enough of these that he can usually identify the failure from a photo before dispatch, and our technicians arrive in uniform with a live arrival time you can track on your phone. Show you the part, write you the price, fix it right the first time. Call us at (619) 541-7844.
FAQs
In San Diego’s climate, expect 8 – 12 years from a Linear keypad and 10 – 15 from a receiver, but coastal salt air in areas like La Jolla, Del Mar, and Point Loma can cut lifespan on the low end. Inland heat in places like Santee and El Cajon is harder on capacitors, which shortens receiver life. If your unit is older than a decade and showing intermittent issues, replacing it now costs less than nursing it another year.
Sometimes, yes. If the failure is a corroded connector, a blown capacitor, or a worn keypad membrane, we can often repair the board or swap the membrane rather than replacing the whole unit. We’ll tell you honestly which option makes sense for your Linear model and how much each costs before we do anything.
Most Linear keypad and receiver replacements take 30 – 60 minutes on site. Telephone entry or full access panel swaps run 1.5 – 2.5 hours when we’re running new wiring or replacing the enclosure. You’ll know the exact timeframe when we quote the job.
We stock the most common Linear keypads, receivers, and access panel components on our trucks, along with aftermarket match parts for discontinued models. If your specific Linear part isn’t on hand, we can typically source it within 1 – 3 business days and give you a firm install date when you book. We also keep parts for LiftMaster, Mighty Mule, and Ghost Controls on hand for multi-brand properties.
If you’re dealing with a dead Linear keypad, a receiver that stopped hearing every remote at once, or a call box that’s gone silent, call Calder Gate Repair San Diego at (619) 541-7844. A live person answers 24/7, we’ll get you a written price before any work starts, and we’ll schedule a technician with a real arrival time that you can track.
