Four-button ECA compatible remote for 81CR, 82CR, 84CR and ACR-6 receivers
Matched to ECA receivers — look for the white Roman numerals
This replacement transmitter is engineered for ECA systems, covering the 81CR, 82CR, 84CR and ACR-6 along with all ECA receivers. The identifying detail to check is the markings on your current remote: it must match remotes featuring white Roman numerals, which is the signature of the compatible ECA family. Transmission runs at 433 MHz with rolling code security, so each press sends a fresh code that cannot be captured and replayed. With four buttons on board, a single unit can control up to four different doors or gates across the property. ECA receivers appear on gates and garage doors in many older Australian installations, and original transmitters can be hard to track down through general retailers.
Ready to code the day it arrives
The purchase includes a free 27A 12V battery already supplied, free coding instructions and a free key ring, so setup requires nothing beyond the box contents. The case is compact at 3 by 5.5 by 1.2 centimetres, small enough to vanish onto a keyring yet solid in the hand. Coding follows the included instructions and takes only a few minutes per receiver. At $17.95 this is an economical way to add a remote for a new driver, replace a lost unit or keep a programmed spare inside the house for guests and deliveries. Rolling code systems register through the receiver's learn procedure rather than simple cloning, which the instructions explain clearly, and noting the coding date on the manual helps when you add more remotes later.
Other gate systems covered in our range
Because gates and garages on one property often come from different suppliers, we stock the neighbouring brands too. The Mhouse MyHouse TX3 TX4 GTX4 remote control handles Mhouse systems at 433.92MHz, the BFT Mitto B RCB TX2 TX4 remote suits BFT motors, and Centurion owners can take the Centsys Centurion NOVA gate remote replacement. Each has its own visual match rules, so compare your existing remotes against the listing photos before adding them to the cart. One combined parcel beats chasing three different suppliers for three different gate brands.
Why order from The Remote Factory
ECA transmitters are a specialist item, and sourcing them is easiest from The Remote Factory, an Australian-based store devoted to replacement remotes and key fobs. All orders are dispatched within 24 hours, and standard delivery takes one to five working days for Australian addresses or two to eight working days to New Zealand. Pay at checkout with Visa, Mastercard, American Express, PayPal, Shop Pay or Apple Pay. The 30-day return policy covers any compatibility surprises, though emailing a photo of your current remote to contact@theremotefactory.com.au beforehand usually removes the guesswork entirely.
Frequently asked questions
How do I confirm this remote suits my ECA system?
Two checks apply. First, your existing remote must feature white Roman numerals, the marker of the compatible ECA remote family. Second, this transmitter works with 81CR, 82CR, 84CR and ACR-6 models and all ECA receivers, so confirm your receiver belongs to the ECA range. If both conditions hold, the remote will code to your system using the free instructions included.
What is included in the box with this transmitter?
You receive the four-button ECA compatible remote, a free 27A 12V battery already supplied, free coding instructions and a free key ring. Nothing else is needed to get started — the battery powers the unit immediately and the instructions cover the coding procedure step by step. The compact 3 x 5.5 x 1.2 cm case attaches straight to your keys.
Does this ECA remote use rolling code security?
Yes, it uses rolling code at a 433 MHz transmitter frequency. Rolling code changes the transmitted signal on every press, preventing code-grabbing attacks that can defeat older fixed code systems. That means replacing your original ECA remote with this unit maintains the security level of the system rather than weakening it, while the four buttons add multi-door convenience.
Can one remote operate several gates or doors?
It can. The four buttons can each be coded to a different compatible ECA receiver, allowing a single transmitter to control up to four doors or gates. That suits properties with a pedestrian gate, driveway gate and garage on separate receivers. Each button is registered individually during the coding process described in the included instructions, so you choose which button runs which door.
