3 Pcs 433MHz Copy Remote Opener, Universal Garage Door Controller Wireless Cloning Key Fob 4 in 1 Remote Control Duplicator, for Electric Gate Car Alarm doors Home Store Roller Shutters Smart Home

I bought after reading reviews to get a spare parking garage door remote instead of my old bulky 433Mhz fob.Set up was fast, all 3 fobs programmed and work.The fob is compact, sized like an AA battery and operates using 27A 12V battery.I used instruction from a review by Darren Knott: In my case programming went like this. 1) Press A&B together (make certain the light doesn't come on, if it does try again, you must press down at the same time. 2) Keep pressing B let go of A and press A down 3 times - light will flash. 3) let go of both buttons. 4) Press original remote button and the clone remote button together, KEEP holding them for a good 30-60 seconds - the clone light will (eventually) flash x2 quickly, pause flash x3 slowly pause then flash x2 quickly. 5) let go of both buttons and test the clone remote.

I ordered at about 02.30 in the morning and paid a little extra for delivery later that day before 10pm. It arrived at about 7.30pm as promised, brought by a cheerful delivery driver. Five stars for that, but...I tried the product immediately on receipt. The instructions were reasonably clear by modern standards, though I had read them before online, and that is where satisfaction ended. Following the instructions, I cleared the memory of the new product then took my old unit to program the new. I followed the instructions and got all the responses described on the new unit. I tried to open the door: the receiver unit on the door flashed a response but the door remained shut. I tried again three times with no response. I then opened the door using the manual controls, and tried to close it with the new unit, but it failed to work so I checked it out using my original contoller successfully.I thought that, perhaps, it was just a defective unit, so I tried with the other two units supplied. They failed equally to open anything, one not even responding as it should to clearing its memory. The whole kit was lacking in function and not of the quality demanded. While trying to set it up, two other points were noticed: firstly, when pressing the buttons they tended to stick in when the edge of the button caught under the edge of the hole it fitted into; secondly, the whole device was flimsy and I had no doubt that, had it worked, it could be easily damaged even with gentle use, and would fail quickly due to poor design and manufacture.My advice would be to leave it alone, do not touch it, and to look at other products.

I bought this set to solve the problem of one remote (gate entry) for three cars. Good for security/safety as my Granddaughter did not like having to get out of her car in the early hours to key in the keypad code as there is a lot of bushes close by.Before i bought this product i read the reviews and noted that most reviewers had a problem programming one or more devices. I followed the instructions exactly and i did not experience any problem. The old remote had a delay of 4 seconds before the gate opened. So i waited for the new ones to operate in the same way and each one worked as expected.

These seemed fine at first, easy to program and they all worked first time but only last a few days, then you need to reprogram them again and that also only lasts a day or two. I keep getting stuck outside my gate! Will be changing for a different brand. Buy cheap & buy twice.

They do work if you get the programming sequence correct, unfortunately as is evident below this changes depending upon the batch you receive. In my case programming went like this. 1) Press A&B together (make certain the light doesn't come on, if it does try again, you must press down at the same time. 2) Keep pressing B let go of A and press A down 3 times - light will flash. 3) let go of both buttons. 4) Press original remote button and the clone remote button together, KEEP holding them for a good 30-60 seconds - the clone light will (eventually) flash x2 quickly, pause flash x3 slowly pause then flash x2 quickly. 5) let go of both buttons test the clone remote. This worked first time on the second and third remotes, and they all tested correctly.

Tried and tried but couldn't get it to program

very easy to use worked verry well

This was a bit of a gamble but product was marked as free return so nothing to lose. However it worked first time, there were 3 in the pack and small set of folded instructions. Picture shows the fob next to the unit it replaced. Old unit had sliding switches inside but obviously the new unit just copies the radiated signal, very happy for the price!
