Linear Gate Access Control in Katy: What to Know First
We service Linear gate access control systems across Katy as an independent provider, meaning we fix keypads, receivers, intercoms, and card readers without pushing you toward a full gate replacement. Most Linear access-control repairs in Katy neighborhoods run between $185 and $520, and we can typically get a technician out within 48 hours for non-emergency work. You’ll get a written price before any tool comes off the truck.
This page is for homeowners with a Linear keypad stuck blinking, a remote that stopped working after a storm, or an intercom that rings but won’t release the gate. If that’s you, call (346) 818-3319 and a live person answers, any hour.
Key Takeaways
- Linear access-control repairs in Katy generally cost $185 to $520, with the price written before work starts.
- We service the Linear product lines most common in Katy homes: the old Multi-Code receivers, the APeX series, and the older IEI/LP keypads.
- Linear’s failure modes are usually electrical and specific: receiver drift, keypad corrosion, and relay cold-solder joints.
- We photograph every connection we touch and leave you a written record of the part number installed.
How Linear Products Fail - and How We Fix Them
- Multi-Code 1099/4120 receiver drift. These receivers were everywhere in Katy subdivisions built in the 2000s, and their tuning drifts over time. The symptom is a remote that works from 10 feet but not 40. The fix is a re-tune or, more often, a swap to the 3089 series receiver, which holds its frequency better. We carry both.
- APeX 2000 series keypad key corrosion. The membrane keys on these keypads fail in Katy humidity, especially on gates that face west into afternoon sun. A key that requires three hard presses has a corroded contact pad, not a bad board. We replace the pad and reseal the housing rather than selling you a new keypad.
- IEI/LP relay failure. The relay that fires the gate motor opens or welds shut, so the code reads correctly but the gate doesn’t move. This is a $40 part. The cheapest unnecessary repair we see in Katy is a full control-board replacement for what is, in Linear’s wiring diagram, a field-replaceable relay.
- Intercom phone-line incompatibility. Some older Linear phone-entry units were built for legacy copper pairs and won’t reliably trigger on VoIP lines common in newer Katy homes. We test the line voltage at the control box before condemning the unit. When the phone line isn’t compatible, we can add a cellular bridge without replacing the entire entry system.
- Water intrusion at the keypad backplate. Linear outdoor stations need the backplate sealed against the gate post. In Katy’s heavy spring rains, a station mounted without silicone around the top edge wicks moisture into the ribbon cable. We remount, reseal, and photograph the finished work.
Our Linear Gate Access Control Process

- 1
You call (346) 818-3319. A live person answers and asks what the system is doing, what brand and roughly what age the equipment is. No voicemail loop, no answering service script.
- 2
We send a technician with Linear parts on the truck. Before arrival you get the tech’s name and photo. He or she will know the difference between a Multi-Code and an APeX without asking you to read the model number twice.
- 3
Diagnostics on site. We test the control board, the receiver, and the wiring at the operator. We write down readings: voltage at the transformer, continuity on the relay, the keypad’s transmit range. Then we show you what we found.
- 4
Written price and parts decision. We quote OEM Linear parts where warranty compliance matters, and we’ll tell you when a quality aftermarket part does the same job for less. The price is handed to you before we start.
- 5
Repair and eye-witness test cycle. We fix it, test it 20 or more cycles, and check the safety edges and photo eyes after the access device is working. On garage gates and driveway gates alike, we confirm the gate reverses on an obstruction rather than forcing the motor through it.
- 6
Documentation and guarantee. You get a photo log of the before state, the work performed, and the after state, plus a written record of the part number and the date. Every Linear job is covered by our 365-Day Done Right Promise: if the repair isn’t right within a year, we make it right at no charge.

AfterWhat Linear Gate Access Control Costs in Katy
Here are the price ranges we quote most often on Linear access-control work in Katy:
| Job | Typical Range |
|---|---|
| Multi-Code receiver re-tune or replace | $185-$340 |
| APeX keypad pad replacement (parts/labor) | $195-$375 |
| IEI/LP relay or transformer replacement | $210-$410 |
| Phone-entry system line test and bridge | $260-$520 |
| Full Linear access-control integration with a modern operator | $420-$1,100 |
What moves the price is the age of the unit, whether the wiring at the gate post is corroded, and whether we’re matching to a modern operator that uses a different signaling protocol. You’ll see the number in writing before we start, and you’ll see the photo record when we finish. Call (346) 818-3319 for a free estimate on your exact setup.
Why Katy Homeowners Call Vance Gate Repair Katy for Linear Work

Because we write down what we find, and we leave the record with you. That’s the Haven Standard we’ve run since Adrian Vance started the company in 2014 out of commercial access-control work. Most Katy gate companies will give you a verbal estimate and a handshake. We give you a written scope, a written price, and a photo log on every visit.
We also don’t push you to replace the Linear system just because we sell something else. If it’s repairable, we repair it. And if the day comes when a new operator makes sense, we service LiftMaster, Mighty Mule, Ghost Controls, DoorKing, and the rest of the field, so you’re not told the only way forward is a brand you never asked for. A live person answers our phone 24/7. Name what you found. Name what it costs. Name what you left behind.
FAQs
Same-day service is possible for access-control emergencies in Katy, but we don’t promise a dispatch time we can’t keep. For a non-emergency keypad or receiver issue, we typically schedule within 48 hours. Call (346) 818-3319 and tell us what the gate is doing; we’ll give you an honest window for a visit.
If your Linear equipment is still under the manufacturer’s warranty, we use OEM parts and document the work so the warranty stays intact. As an independent Linear service provider, we’re not affiliated with or authorized by Linear, but we follow their wiring diagrams and torque specs on every job we touch.
Until the receiver board is cracked or the housing is structurally shot, a receiver swap is almost always cheaper than a full access-control upgrade. We’ll show you the re-tuned or replacement receiver working at 40 feet before we take payment. If you decide later you want phone or app entry, the new receiver doesn’t lock you out of that upgrade path.
For most Linear residential lines, yes. We stock Multi-Code 300-series receivers, APeX keypad membranes, IEI relays, and the common transformer sizes. If your unit needs a part we don’t carry, we quote it the same day and order it; no deposit, no obligation.
