Linear Keypad & Intercom Repair: The Houston Owner’s Guide
Linear keypad and intercom repair in Houston typically runs $180-$420 installed, depending on whether the fix is a simple keypad swap or a full intercom station with wiring troubleshooting. We stock the common Linear keypad and intercom components on our trucks, and most Houston-area calls are completed same day. Homeowners usually discover the problem on a humid Houston morning when the keypad won’t accept their code, the intercom crackles with static, or the gate simply sits silent after they press the call button.
Which Linear Models This Applies To
Linear keypads and intercoms span several product families, and matching the right replacement matters more than with some other brands because Linear uses proprietary communication protocols between certain entry devices and their control boards.
The ACP (Access Control Plus) series covers most residential keypad installations in Houston, including the ACP00960 and ACP00970 wireless keypads. These communicate on Linear’s MegaCode format, which means a generic keypad won’t handshake with a MegaCode receiver. The AE (Access Elite) line handles heavier commercial traffic. For intercoms, the Linear RE-1 and RE-2 residential entry systems remain common in gated communities from The Woodlands to Sugar Land, while the AE-100 and AE-500 series serve larger properties.
To identify your unit, check the label inside the keypad housing or on the intercom base station. We need the model number, the frequency if it’s wireless (318 MHz is standard for older Linear), and whether your system uses the two-wire or four-wire intercom configuration. The two-wire setup is more common in Houston homes built between 1995 and 2010, but we’ve found developers in Cinco Ranch and Cypress favored four-wire runs for longer driveway distances.
OEM Linear parts guarantee protocol compatibility and carry the factory warranty. Quality aftermarket equivalents exist for keypads, though we avoid them for intercom master stations because the audio matching rarely satisfies. We’re an independent service provider, not affiliated with Linear, so we stock both and will tell you what it needs, not what sells.
Signs Your Linear Keypad & Intercom Repair Is Failing
- Keypad buttons become unresponsive or require hard presses. The membrane switch beneath the buttons degrades from Houston’s UV exposure and humidity cycling. On south-facing gates in Memorial and Bellaire, we’ve seen this failure in as little as four years.
- Intercom audio is garbled, faint, or one-way only. The speaker or microphone element has failed, or corrosion has set in at the wire terminals. Houston’s coastal humidity accelerates this; we find green copper oxidation at the junction box on roughly half the intercom calls we make near Clear Lake.
- Keypad accepts the code but the gate doesn’t open. The keypad’s output relay has failed, or the wireless transmitter isn’t reaching the receiver. Distance matters: a wireless keypad at the end of a long River Oaks driveway may lose signal where a wired unit wouldn’t.
- Backlight works but no numbers register. The controller board inside the keypad has separated from the button matrix, often from thermal expansion in direct summer sun. Black housings absorb more heat; we’ve measured keypad surface temperatures above 140°F in July.
- Intercom call button triggers the gate but no voice connection. The call routing circuit is intact but the audio path is broken, usually a failed transformer or corroded connection at the gate’s base.
Replacement Cost & What’s Included
| Service | Typical Range |
|---|---|
| Linear keypad replacement (wired, standard) | $180 - $290 |
| Linear keypad replacement (wireless/MegaCode) | $240 - $340 |
| Linear intercom station repair (single component) | $160 - $260 |
| Linear intercom station replacement (full unit) | $320 - $420 |
| Wiring troubleshooting or run replacement | $85 - $150 additional |
What drives the range: wireless units cost more in parts, long wire runs add labor, and intercom systems with multiple substations take longer to test end-to-end. Every quote is itemized before we start. A square deal: upfront price, no surprises on the bill. The 90-Day Done Right Promise covers all work, and we apply our standing $50 Off Any Repair Over $250 if your total qualifies. Senior and veteran discounts run 5% always.
DIY or Call Us?
There’s safe checking, and then there’s the point where a homeowner can turn a $200 fix into a $600 one.
What you can safely do: verify power at the keypad or intercom (look for any backlight or LED), check that the circuit breaker hasn’t tripped, and confirm the gate operator itself still responds to remote or manual commands. This tells us whether the problem is isolated to the entry device or system-wide.
Where DIY goes wrong: Linear intercoms run low-voltage, but the gate operator’s control board carries line voltage nearby. Crossed wires can damage the board. Keypad mounting holes rarely line up between models, so drilling without knowing what’s behind the stucco or brick invites water intrusion. And programming a new Linear keypad to an existing MegaCode receiver requires a specific sequence; done out of order, you can lock yourself out entirely. We’ve had calls from Tanglewood and West University where a homeowner spent a Saturday on this, then needed us to sort the programming and repair the housing damage.

FAQs
In Houston’s climate, expect five to eight years for a keypad and seven to ten for an intercom station, assuming direct sun exposure and normal use. Units under covered entryways or facing north last longer; we’ve replaced keypads in Spring Branch at twelve years that were sheltered by oak canopy. Call (888) 799-8389 and we’ll assess whether yours has life left or is due.
Sometimes. A failed button membrane or corroded terminal can be repaired if the controller board is intact. Intercom speaker elements are replaceable individually. But if the main circuit board has failed, replacement is more reliable than board-level repair, which we don’t warranty. We’ll tell you which path makes sense when we see it.
Most Linear keypad swaps take 45 to 90 minutes on site. Intercom replacements run 60 minutes to two hours if the wiring is sound and no trenching is needed. We carry common Linear models on the truck, so one visit handles most Houston jobs. Same-day scheduling is typical.
We stock ACP series keypads, RE-1 and RE-2 intercom stations, and common replacement components on every service truck. Less common AE series parts we can source within 24 hours. When you call, we’ll confirm your model and reserve the right part before we head out.
