Ideal For
Homeowners, small businesses, maintenance teams and installers who need a quick replacement or spare remote for 433 MHz access systems. Useful for workshops, property managers, delivery drivers and vehicle owners who want a convenient secondary key fob.

Why Buy
This 433 MHz 4-channel duplicator is an affordable, compact solution for replacing lost remotes or creating extras without reprogramming complex control units. Its multi-mode operation maximizes compatibility with a wide range of legacy receivers while the long control range and low power draw make it practical for daily use.

Important Note — Use Responsibly
For lawful and ethical use only: clone or program only remotes and devices you own or have explicit permission to modify. Misuse (unauthorised access to property or vehicles) is illegal and unsafe.

Interesting Fact
Many access remotes still use simple fixed codes or basic learning functionality because these systems are inexpensive and reliable. That’s why universal duplicators remain popular for maintenance and replacement — they bridge older legacy systems and modern convenience without requiring changes to existing control hardware.
