We stock and install Linear-compatible keypads and intercom components across San Jose, with most keypad replacements running $185 – $340 installed and intercom module repairs typically landing between $220 – $410 depending on the model and wiring condition. Same-day service is available when we have your specific part on the truck, which covers the most common Linear keypad models.
Most San Jose homeowners discover the failure the hard way: the keypad accepts the code but the gate won’t move, or the intercom rings but you can’t hear anyone on the other end. Sometimes it’s a dead keypad after rain. Sometimes it’s a code that works for the delivery driver but not for you. By the time we get the call, the part has usually been failing for weeks in ways that were easy to miss.
Which Linear Models This Applies To
Linear’s keypad lineup splits into two main families: the AK series (AK-11, AK-11P, AK-21) and the older AM series. The AK-11 is the workhorse we see most often in San Jose driveways, usually paired with Linear’s LRA or APeX gate operators. The intercom side depends on whether you have a Linear AE-500, AE-1000, or one of the legacy units wired into a multi-tenant box.
Here’s the compatibility gotcha that trips people up: the AK-11 and AK-21 look nearly identical from the front, but the AK-21 is a 2-door controller, not a single-gate keypad. If you buy an AK-21 thinking it’s a drop-in replacement for an AK-11, you’ll have a second relay output you don’t need and a wiring configuration that doesn’t match your existing harness. We see this mistake at least once a month from well-meaning DIY attempts.
For OEM versus aftermarket: Linear still makes genuine AK-11 keypads, and we prefer OEM for anything that lives outdoors year-round. The aftermarket equivalents can work, but in San Jose’s wet winters and dry summers, we’ve seen cheaper knockoff keypads develop membrane cracks within 18 months. If you’re replacing a keypad that’s already failed once, we’ll always recommend the genuine Linear part unless budget forces otherwise. We’re an independent service provider, not affiliated with Linear, but we work with their parts daily.

Signs Your Linear Keypad & Intercom Repair Is Failing
- Keypad accepts the code but nothing happens. This usually points to a failed relay on the keypad’s board or a broken wire between the keypad and the gate operator. The keypad beeps, the backlight works, but the signal never reaches the motor.
- Backlight is dead or flickering. Linear keypads are membrane-sealed, but after 4 – 6 years in San Jose sun, the seal starts to go. Moisture gets in, the backlight shorts, and corrosion spreads across the board. A flickering keypad won’t stay working much longer.
- Intercom rings but audio is garbled or one-way. This typically means a failing speaker or microphone module inside the intercom housing. On Linear units, the issue is often a corroded connection at the wiring block, not the module itself, which is a cheaper fix than most people expect.
- One specific code stops working while others still function. Linear keypads store codes in non-volatile memory, but a failing memory chip can drop individual user slots. It’s not user error. The board is telling you it’s on the way out.
- You have to press buttons multiple times before the digit registers. This is a failing membrane. Once the contacts under the buttons wear out, the only real fix is a new keypad. We’ve never seen a membrane repair that lasts longer than a few months.

AfterReplacement Cost & What’s Included
For a standard Linear AK-11 keypad replacement in San Jose, expect to pay $185 – $340 installed. That includes the part, labor, wiring inspection, and programming all existing codes into the new unit. If you’re dealing with an intercom module rather than a keypad, the range is $220 – $410 depending on whether we’re replacing a speaker, a microphone, or the full module, and how much of the existing wiring is salvageable.
The range depends on three things: which Linear model you have, how corroded the existing wiring is, and whether we need to run new low-voltage wire from the keypad or intercom to the operator. Every quote includes a written itemized price before we open the tool bag. The number on the invoice is the number we agreed to at your door.
Every keypad and intercom replacement carries our 365-Day Done Right Promise. If the repair fails within a year, Calder Gate Repair returns at no charge. That’s not a verbal promise. It’s written on the job paperwork.
DIY or Call Us?
There are a few things you can safely check before calling. Confirm that power is reaching the gate operator. Check the breaker. Look at the keypad’s wiring for obvious rodent damage or a pulled-apart wire nut. If you see a corroded connection at the keypad, tightening things up isn’t a safe bet with low-voltage wiring that’s been outside for years. The splices break, and a bad connection at the board can fry the new keypad too.
What we wouldn’t attempt as a DIY repair: anything involving the keypad’s internal board, the relay, or the intercom wiring block. Low-voltage doesn’t mean no-risk. A crossed wire at the operator board can kill the whole gate controller, which turns a $250 keypad replacement into an $800 operator repair. If the keypad isn’t working and you’ve already confirmed the breaker is fine, call us at (669) 666-6859. Nico Alvarez and the crew can usually have a Linear keypad diagnosed and replaced the same day.
FAQs
A genuine Linear AK-11 typically lasts 5 – 7 years in San Jose’s climate before the membrane seal degrades and moisture becomes a problem. If you’re on a south-facing wall with no shade, expect closer to 4 years. Aftermarket units usually need replacing every 2 – 3 years, which is why we prefer OEM parts for outdoor applications. Call (669) 666-6859 and we can look at your existing unit and give you a realistic lifespan for your install location.
Not in a way that lasts. The membrane, backlight, and board are a single sealed assembly on AK-series keypads. We can sometimes fix a loose wire or corroded splice, but when the membrane or board fails, replacement is the only repair that holds. We’d rather tell you that up front than charge you for a patch job that fails in six months.
A standard Linear keypad replacement takes 45 – 90 minutes on site, including wiring inspection and code programming. An intercom module replacement runs 1 – 2 hours depending on how much of the existing wiring we need to replace. We’ll give you a live, trackable arrival time when you book, so you’re not waiting through a four-hour window.
We stock the AK-11 and AK-21 series on our San Jose trucks, plus common intercom replacement speakers and wiring blocks. For older AM-series keypads or less common intercom modules, we can typically source the part same-day from our local supplier or have it in hand within one business day. Beyond Linear, we carry parts for LiftMaster, Mighty Mule, and Ghost Controls systems as well. Call (669) 666-6859 with your model number and we’ll tell you exactly what we have before you book.
If your Linear keypad or intercom is acting up, don’t wait for a full failure. A dead keypad means a blocked delivery, a missed visitor, or worse, a gate that’s stuck open when you need it closed. Call Calder Gate Repair San Jose at (669) 666-6859. We’ll have a live person answer, give you a straight answer on parts availability, and put the price in writing before any work starts.
