Have an 8 year old wireless alarm system. One pensive and basic but worked well. Came with one fob. The Chinese manufacturers seemed to disappear after a couple of years. I bought what elements I could as spares from my supplier. But couldn't get a fob.psu failed..used an old laptop charger. External solar siren failed..hard wired new on. The fob looked on its last legs, I could operate the keypad. But we got used to the fob. Took a punt on one of these. Forget the manual, it's like a word salad...there are instructions here and online. But for some reason they don't seem to work out of the bag. It took me two days to get it going.but it works well and better build than the original. Tip...the key thing is to get the indicator light flickering ( mine is blue). Use the two button a and b clear action one blue flash. Pair old and new buttons and hold until the light flickers fast. Repeat for others. Must have taken me 20 goes. You may have to hold the buttons for 1 Mon or longer...be persistent.Bout a second as back up if my original fails.Only 4 stars as manual useless and no battery replacement info ? Looks like the back unscrews.

Returned as didn't work

Worked well seems well made too.

Key fob broken. This new one programmed easily but on is A off is C which takes some getting to.

have bought 2 of these cheap garage wireless cloning devices, one worked perfectly, this brand does nothing. I dont recommend it, waste of money. They both say the same thing and look similar.
