Universal 433 MHz RF remote

The Ruth's sister 433 MHz 4‑button RF remote control operates at 433.92 MHz using ASK modulation. Four channels let you clone commands for garage doors, vehicle alarms or home security systems. A 12 V 27A battery is included and the unit draws 8 mA while transmitting at 100 mW. The ABS housing keeps the device light and pocketable.

Compatibility check before ordering

Verify that the target receiver works on 433 MHz with ASK encoding before purchasing. The cloning procedure requires physical access to the original transmitter so both units can be placed side by side. No smartphone application or software configuration is supported. Ensure the device you intend to control accepts a 4‑button layout.

Build and daily use

The ABS plastic shell resists everyday knocks and fits easily in a pocket or on a key ring. Four tactile buttons provide distinct control points without accidental activation. Power comes from the supplied 12 V 27A cell, delivering 100 mW output for reliable short‑range operation. The simple clone method means new codes can be added in seconds.

Questions about this item

Does the remote arrive with a battery or must I buy one separately?

A 12V 27A battery is supplied inside the handset so no separate purchase is needed.

The product lists a single 4‑button version; is there any capacity or frequency choice to make?

Only one variant exists — four buttons at 433.92 MHz — so there is no capacity or frequency option to select.

What does the 433.92 MHz figure mean once the remote is paired with my garage door?

It sets the radio carrier frequency; the clone procedure copies the original remote’s code so the receiver recognises each button press.
