There are two different Centurions in Australian driveways, so identify yours before ordering a remote. Centsys Centurion gate motors use the NOVA remote family, while Avanti Centurion garage door openers take TX4-style remotes. The two families are not interchangeable, so check the brand on your motor housing first and the right replacement becomes obvious.

Two Centurions: Centsys gate motors vs Avanti garage openers

The name Centurion causes more confusion than any other in this category. Centsys, a gate automation maker, sells sliding and swing gate motors under the Centurion name, and those systems answer to NOVA remotes. Separately, Avanti markets Centurion-branded garage door openers, and those units respond to TX4-type remotes. Searching for a Centurion remote without knowing which camp your motor sits in is how people end up with a transmitter that will never pair. Walk out, read the label on the motor itself, and note every model reference you can find.

The quickest tell is where the motor lives. A unit mounted beside a sliding or swing gate at the fence line is almost certainly a Centsys gate motor. A unit bolted to the ceiling of the garage, driving a roller or panel door, points to an Avanti Centurion opener. Once you know which one you own, the remote family follows automatically, and everything on the product page will either line up with your references or clearly rule itself out.

NOVA remotes for Centsys gate motors

If your sliding or swing gate runs on a Centsys motor, the Centsys Centurion NOVA Blue replacement remote is the straightforward swap. It suits households replacing a single lost or worn transmitter. Where two cars need access, the NOVA Blue remote two-pack for Centsys covers both drivers in one order and means each vehicle keeps its own transmitter rather than sharing one across the household.

TX4 remotes for Avanti Centurion openers

Garage doors are a different story. Avanti Centurion openers pair with TX4-style transmitters, and the listings to look for reference TX4 alongside MPS, DPS and SDO21/12. A single Avanti Centurion TX4 compatible garage remote sorts a lost or broken handset, while the Avanti Centurion TX4 remote twin pack suits anyone who wants a spare in the kitchen drawer as well as one on the visor. Compare the references printed on your original transmitter with those in the listing before you commit.

Which remote family do you need

Programming through the onboard receiver

Both families learn new transmitters through the receiver built into the motor unit, and the routine is similar in spirit even though the button locations differ. In broad terms: get safe access to the motor head, find the learn button on the receiver board, press it to put the unit into learning mode, then press the chosen button on your new remote until the motor acknowledges it. Test from a few metres away, then again at normal driveway range. While you are at the motor, it is worth deleting any lost remotes from its memory if the manual shows how, since a cleared receiver is the simplest protection after a handset goes missing. For model-specific walkthroughs, see our guide to programming garage remotes for ATA, Merlin and Centurion systems, which covers the common learning sequences step by step.

Check the code type before you buy

A quick compatibility check saves a return. First, photograph your existing remote front and back, since model references often hide near the battery door. Second, confirm the motor brand and model from its label. Third, remember the general rule that rolling-code remotes cannot be duplicated by fixed-code cloning devices, so a genuine learning sequence at the receiver is the reliable route. If anything about codes or frequencies still feels murky, our explainer on garage remote frequencies, codes and model matching breaks down what actually has to line up.

Every order leaves our Australian warehouse within 24 hours on business days, with delivery across Australia usually taking between 1 and 5 working days. As an Australian-based specialist store we deal with these remotes daily, and a 30-day return window applies if a transmitter does not suit your motor.

Frequently asked questions

Are Centsys NOVA and Avanti Centurion TX4 remotes interchangeable?

No. They belong to two unrelated product lines that happen to share the Centurion name. Centsys gate motors learn NOVA transmitters, while Avanti Centurion garage openers learn TX4-style transmitters, and neither receiver will accept the other family. Before buying, read the label on the motor unit itself rather than relying on the word Centurion alone, because the brand on the label tells you which remote family your system actually needs.

How do I program a new remote to my Centurion gate or garage motor?

Both families learn new remotes at the receiver inside the motor unit. The general sequence is to access the motor head safely, press its learn button to enter learning mode, then hold a button on the new remote until the unit signals acceptance. After that, test operation at normal range. Exact button names and light signals vary between models, so check the walkthrough in our programming guide or the manual for your specific motor.

Can I clone my existing Centurion remote instead of programming one?

Generally no. Modern gate and garage systems use rolling codes, which change with every press, and rolling-code remotes cannot be copied by fixed-code cloning gadgets. The dependable approach is a compatible replacement learned directly at the motor's receiver, which registers the new transmitter the same way the original was registered. Cloning only ever worked for older fixed-code systems, and relying on it today usually ends in a remote that operates nothing.

What should I check before ordering a replacement gate remote?

Three things. Note the brand and model printed on the motor unit, since that decides the remote family. Photograph your current remote, including any references near the battery compartment, such as TX4, MPS, DPS or SDO21/12 on Avanti units. Then compare those references against the product listing. If every reference lines up and the motor brand matches, the replacement should learn normally; if anything differs, ask before buying rather than guessing.
