4 Bands 315/418/433/868MHZ Multifrequency Universal Automatic Car Cloning Remote Control Copy Duplicator for Door Light

Item is a piece of junk. No instructions supplied. Not worth it's price

Item doesn't work. It's impossible to clone from current remote key.

there are no instructions to program it. I managed to program it. Instructions: 1) The rest of the new remote control: a) keep A and B pressed simultaneously b) without letting A give 3 impulses to B after this reset, when the keys are pressed, the LED does not emit any light. 2) Programming: a) press and hold down button A on the new remote control, press and hold down button A on the old remote control until the LED on the new remote control stops. b) continue in the same way for the other keys.

Great, it works perfectly, programming it was very easy, much easier than you can imagine. Perfect I recommend!
