AfterLinear Access Control Installation: The Gardena Owner’s Guide
Linear access control installation in Gardena typically runs $450 to $1,200 installed, depending on whether we’re replacing a failed keypad, adding a new telephone entry system, or modernizing an older Linear controller with newer hardware. Most Linear access control swaps on a sliding driveway gate take us two to four hours on site, and we carry the most common Linear entry components on the truck. Homeowners usually call us after the keypad goes dark, the gate stops responding to remotes, or a tenant’s access code simply stops working one afternoon.
We’ve been working on Linear equipment in Gardena driveways since the early 1980s, and the pattern is consistent: these systems work quietly for years, then one component fails and everything downstream acts strange. You don’t need a whole new gate. You need the right part matched to your Linear model and installed by someone who has done it a few hundred times. That’s the job we do.
Which Linear Models This Applies To
Linear manufactured its access control line in overlapping series over the decades, and the compatibility details matter. The most common units we see in Gardena are from the MegaCode and Multi-Code families, along with newer PRO Access and AE series controllers. Older Garage Guard and Delta-3 receivers still turn up on estate gates in the Hollywood Riviera and along Western Avenue, and they have their own wiring quirks.
Before you order any replacement part, look for the model plate on the controller housing or the receiver module. It will list a model number like AP-5, AE-1000, MCT-3, or similar. That number determines everything: wiring layout, remote compatibility, and whether you can mix newer transmitters with an older receiver. Linear’s MegaCode protocol uses rolling-code technology, so a MegaCode remote will not talk to a Multi-Code receiver, even though both names start with “Multi.” That single gotcha has cost Gardena homeowners plenty of wasted time over the years.
The OEM-versus-aftermarket decision for Linear is simpler than most brands. Linear keypads and receivers are still widely available as genuine OEM parts, and the price difference for aftermarket equivalents is rarely worth the risk of mismatched wiring harnesses or weaker weather sealing. For remotes and transmitters, quality aftermarket clones from companies like Remocon work fine and save real money. For the controller board itself, we always recommend OEM Linear. The board is the brain, and a $40 savings on a no-name board is poor economy when it fails in a year.
Signs Your Linear Access Control Installation Is Failing
- The keypad lights up but the gate won’t move. This usually points to a failed relay on the controller or a broken connection between the keypad and the gate operator. The keypad is talking; the signal isn’t reaching the motor.
- Remote transmitters work sometimes, but not consistently. Intermittent operation on Linear systems often traces back to a weakening receiver or antenna corrosion, especially on gates close to the marine layer in Gardena’s lower streets.
- One access code stops working while others still function. This is almost always a programming issue within the controller itself, not a failed part. A failing memory module can also drop learned codes, and that means replacement rather than reprogramming.
- The gate opens fine but won’t close without holding the button. This points to a failed safety input or a misaligned loop detector, not the access control itself. But on combined systems, the controller can be the culprit if it’s sending a constant open command.
- You hear a click at the controller but nothing at the gate operator. That click means the relay is trying to fire. If the operator is fine, the likely cause is a burned relay contact inside the Linear board, a common failure after years of daily cycling.
Replacement Cost & What’s Included
For Gardena homes, a straightforward Linear keypad replacement typically lands between $450 and $650 installed. A new receiver and controller board runs $600 to $900. Full replacement of an aging Linear telephone entry system with a modern keypad, new receiver, and reprogrammed remotes sits around $900 to $1,200. Parts are roughly 40 to 60 percent of the bill; the rest is labor, wiring verification, and programming. Every price is settled before we touch a bolt.
Here’s what your installed price includes: the correct Linear or quality-compatible part for your exact model, removal of the old component, verification of the wiring between the access control and the gate operator, programming of all existing remotes and keypads, and a walk-through test of every function before we pack up. The work is covered by our 90-Day Done Right Promise in writing. If something isn’t right, we come back and make it right. No paperwork, no arguing.

| Receiver / controller board replacement | $600 - $900 |
| Full telephone entry system modernization | $900 - $1,200 |
| Additional remote transmitters (each) | $40 - $75 |
DIY or Call Us?
There are a few things you can safely check before picking up the phone. Confirm the keypad has power: most Linear units have a small LED or backlight. Check the breaker for the gate circuit and make sure an errant sprinkler hasn’t been soaking the keypad box for years. If the keypad is dark and the breaker is on, that’s a replacement, not a repair. Programming instructions from Linear are available online, and if you’re comfortable matching wire colors and terminal numbers, a keypad swap is within reach for a careful homeowner.
What you shouldn’t attempt is any work inside the controller itself or any wiring between the access control and the gate operator. Gate operators carry 120V or 240V, and the capacitor inside an operator stores enough charge to hurt you long after the breaker is off. We’ve also seen more than one Gardena homeowner accidentally short a controller board while probing it with a multimeter, turning a $500 fix into a $900 one. If you’re not certain, call (916) 398-2696 and talk it through with a live person. We’ll tell you straight whether it’s a phone consult or a service call.
FAQs
A well-installed Linear system typically lasts 10 to 15 years in Gardena’s climate before the controller board or receiver needs replacement. Salt air closer to the coast, sprinkler overspray, and constant sun on the keypad housing can shorten that to 7 or 8 years. Keypads exposed to afternoon sun on west-facing gates fade and crack sooner than shaded ones. If your system is past year 12 and acting unreliable, a targeted replacement now beats a full failure at 6 a.m.
In most cases, no. Modern Linear controllers are solid-state boards, and when a relay burns out or the memory module fails, the board gets replaced as a unit. Component-level repair on these boards is rarely cost-effective compared with a new OEM Linear part. We’ll always tell you if a repair makes sense, but on Linear access control specifically, replacement is the honest answer more often than not. Call (916) 398-2696 and describe the symptoms; we’ll give you a straight read.
Most single-component replacements, like a keypad or receiver, take two to four hours including programming and testing. A full system modernization with new telephone entry and multiple keypads is usually a half-day to a full day. We settle the price before we start, and most Gardena jobs are finished in a single visit. You’ll know the schedule before we arrive, and we’ll be there when we say.
Yes. We keep the most common Linear keypads, receivers, remotes, and controller boards on the truck for same-day service across the Gardena area. For less common Linear components, we can typically source them from our South Bay suppliers within a day or two. If you need a part matched to an older Linear model, call us with the model number from the controller plate and we’ll confirm availability before we roll.
If your Linear access control has finally given up, or it’s been acting unreliable for weeks, call Ironworks Gate Co. at (916) 398-2696. Victor Salinas and the team know Linear equipment the way a gardener knows the difference between Santa Ana wind and marine layer humidity. A gate should open when you need it to. That is the whole job. We’ll quote a fair price, show up when we say, and stand behind the work in writing.
