Elite Keypad & Intercom Repair: The San Mateo Owner’s Guide
Elite keypad and intercom repair in San Mateo typically runs $280-$520 installed, depending on whether we’re replacing a surface-mount keypad, a vandal-resistant intercom station, or both on the same visit. We stock the common Elite-compatible boards and housings on our trucks, and most residential jobs in San Mateo are completed same day once the model is confirmed. Most owners figure out something’s wrong when the gate stops responding to codes entirely, or when visitors press the call button and hear static instead of the house phone ringing.
Which Elite Models This Applies To
Elite has produced several keypad and intercom lines over the years, and the part you need depends on which generation is mounted at your gate. The Elite EK series (EK-200, EK-300, EK-500) are the surface-mount keypads you’ll see on most residential swing and slide gates in San Mateo - they’re identifiable by the white label inside the battery compartment or on the rear housing that starts with “EK-” followed by a three-digit code. The Elite KP-300 and KP-500 vandal-resistant units are the heavy-duty cast-metal housings common on commercial properties and some newer HOA installations near Hillsdale and the Baywood area.
For intercoms, Elite branded the EIS-100 and EIS-200 series (Entry Intercom Station) through roughly 2018, after which the naming shifted toward the EL series. The gotcha: an EK-300 keypad housing will accept an EK-500 circuit board, but the mounting footprint differs by about half an inch. We’ve seen two San Mateo homeowners buy the wrong board online, discover the screw holes don’t line up, and call us to sort it out. We carry both OEM Elite replacements and quality aftermarket equivalents from Preferred Technologies and Security Brands - the aftermarket units run about 15% less and carry the same one-year warranty, though we always confirm compatibility against the existing wiring harness before quoting.
To identify your unit: open the keypad housing (two screws on most models), photograph the label, and note whether your system uses two-wire, four-wire, or wireless communication back to the house. That single detail determines which replacement will drop in without rewiring.
Signs Your Elite Keypad & Intercom Repair Is Failing

- Keypad buttons stop registering presses, or require multiple tries. The silicone button matrix underneath the faceplate degrades with UV exposure - San Mateo’s 260+ sunny days per year accelerate this. Moisture intrusion through cracked gaskets is the second culprit we find, especially on west-facing gates that catch afternoon fog and sun in the same day.
- Gate opens with some codes but not others, or the master code no longer works. This usually points to memory corruption on the control board, not the buttons themselves. Elite keypads store codes in EEPROM, which can fail after roughly 7-10 years of power cycling. We test the board on-site before replacing anything.
- Intercom produces static, buzzing, or no audio at all. The speaker and microphone elements are separate from the keypad circuitry in most Elite units. Corrosion at the terminal block - where the station wire meets the board - is what we find most often in San Mateo’s coastal microclimates. The fix is often a new terminal block and fresh wire seating, not a full replacement.
- Backlight flickers or goes dark while the keypad still functions. The LED driver circuit or the ribbon cable connecting display to board has fractured. This is repairable in some cases, though the labor to micro-solder often exceeds the cost of a replacement board.
- Gate responds to keypad entry but the intercom no longer rings the house phone. The communication path between station and controller has failed - could be wiring, could be the station’s communication chip. We isolate this with a loop-back test before quoting any parts.

AfterReplacement Cost & What’s Included
| Service | Typical Range (San Mateo) |
|---|---|
| Elite keypad replacement (EK series, surface mount) | $280-$380 |
| Elite vandal-resistant keypad (KP series) | $340-$460 |
| Elite intercom station replacement (EIS/EL series) | $320-$440 |
| Keypad + intercom combo replacement | $420-$520 |
| Wiring repair or terminal block replacement (no new unit) | $180-$260 |
What drives the range: the part itself (OEM Elite vs. quality aftermarket), whether the existing mounting box is intact or water-damaged, and whether we need to rerun low-voltage wire from the gate to the control box. Every quote is written and handed to you before work starts - Haven Standard Clause 1. The price you sign is the price on the invoice. Our 365-Day Done Right Promise covers all completed work; if the new keypad or intercom fails within a year, we replace it at no charge, including labor.
DIY or Call Us?

There’s a safe middle ground here. An owner can check the obvious: confirm the breaker feeding the gate controller is on, verify the keypad display lights up (proving it’s receiving power), and look for visible corrosion or insect nests inside the housing. If you’re comfortable with a screwdriver and a non-contact voltage tester, that’s as far as we’d push it.
Where DIY goes wrong: Elite keypads communicate with the gate operator through low-voltage wiring that also carries safety-sensor circuits. Miswiring can disable photo-eyes or reverse-loop detectors without obvious symptoms until someone walks through the gate path. We’ve documented three San Mateo jobs where a homeowner’s keypad swap created a safety-system fault that didn’t surface for weeks. The intercom wiring, meanwhile, often shares conduit with 120V landscape lighting - not a place to guess. If your Elite keypad or intercom is failing, call (650) 293-9440. We’ll confirm the model, quote the repair in writing, and handle the wiring verification as part of the job.
FAQs
Most Elite keypads last 8-12 years in San Mateo before the button matrix or board fails; intercom stations average 10-15 years if the housing gasket stays intact. Coastal fog accelerates corrosion at terminal blocks, so units within a mile of the Bay tend toward the shorter end of that range. Call (650) 293-9440 if yours is showing age - estimates are free.
Sometimes. Button matrix replacement and terminal block cleaning are repairable, but board-level failures (memory corruption, communication chip failure) require a new unit. We test on-site and tell you which path makes sense before quoting. Call (650) 293-9440 to schedule a diagnosis - there’s no charge for the assessment if you proceed with the repair.
Most Elite keypad or intercom replacements take 45-90 minutes once we’re on-site, assuming the wiring harness is intact. If we need to pull new wire from the gate to the controller, add 1-2 hours. We stock common Elite-compatible units on our trucks, so most San Mateo jobs are completed in a single visit. Call (650) 293-9440 to confirm same-day availability.
We stock replacement keypads, intercom stations, and common circuit boards for the EK, KP, EIS, and EL series on our service trucks. For discontinued Elite models, we source quality aftermarket equivalents with identical wiring footprints - no waiting on your end. Call (650) 293-9440 with your model number and we’ll confirm what we have.
We’re independent service providers - not affiliated with Elite Access Systems - and we also stock parts for LiftMaster, Mighty Mule, and Ghost Controls gate operators and accessories.
Name what you found. Name what it costs. Name what you left behind. That’s how we work every job in San Mateo, whether it’s a single-family keypad near Baywood Park or a commercial intercom station downtown.
