OK, the instruction pamphlet is in tiny font and very badly translated but once you work it out this is great.First, clear the buttons:HOLD A + B for 3 seconds - the led flashes. Keep hold of B and tap A 3 times.To program a button (A in this example):Hold A for 3 seconds - the led flashes three times. wait a second or 2. Tap the source button on the other remote. The led will flash a few times then go solid on. That's it.

Worked perfectly first time. Before you buy check your remotes compatible and that should remove the 1 and 3 star reviews!First clear the buttons:Press and hold A and B for three seconds, the led will flash. Now keep hold of B and press A three timesTo programme a button press and hold it for 3 seconds, the led will flash 3 times. Hold the source remote near to this one and tap the button you want to map. The led will flash a few times and then become a solid light.DoneCredit to P. Abbott (previous review) for the clear instructions

Product works fine but you have to have a working, compatible existing key fob. Firstly it has to work on the 433Mhz frequency, this will be written on the fob or garage opener or instruction manual. Second it needs to have compatible RF chip (see photo). Without taking your existing fob apart you probably aren't going to have this marked up or in the instruction book so it is a bit of a gamble. It won't work with rolling codes e.g. the code changes every time the fob is used (like car remotes).It has four independent buttons A,B,C,D. You can programme one, programme all four for the same garage door open, programme for 4 different garage doors etc.To programme first clear the memory of all four buttons by handing A and B together until the blue light flashes, and while holding B down, release and press A three times blue light will flash again.To programme one of the buttons to your existing fob, hold the existing fob about 1cm from the top right of the fob then press and hold the button you want to programme, after the blue light has flashed three times press the button on your existing fob. The fob should flash blue again and (it will emit a signal to the opener)That's it, memory cleared, all four buttons programmed in less than 30 seconds. Working range is around 10metres. Comes with battery, but replacement is an A27 / MN27An original 433Mhz Cardale 650n replacement is £50+, two fobs for £13, very happy.

Having had quotes off £300 and £180 to obtain a spare key to my shop shutter (rented premises) a friend suggest a clone. The consensus was before spending hundreds try the cheap stuff first. Both keys took less than a minute to clear and clone - so simple!The next day I returned to open up and tried the key. Both work exactly the same as the original and better. The original keys breaks signal and causes shuttering (likely battery) but these keys provide a smooth clean close every time with no break in signal.I would highly recommend these keys before splashing out - my door isn't a garage door - it's a shop shutter so you just never know how lucky your day is gonna be!!!

What a wonderful product - Does exactly what it's supposed to and makes for a very neat remote control. A few niggles however - The instructions are so small a 10x magnifier is needed to follow them. I scanned the small copy and enlarged for printing. The setup is straight forward once you've had a go. Results are superb. Finally the cost. Ebay selling for a quarter of the price but are inferior products so be warned. Used mine for 4 function GSM Alarm System and perfect. These are highly recommended. Very pleased indeed.

OK so they do work, sort of. I followed the instructions correctly and they will open my garage door. However I have to press the button repeatedly the garage door will open after about 10 or 20 presses of the button. The range is about half that of the original fob. Save the hassle and buy a proper replacement for your garage door.

Does not work with rolling code controllers so no use to me did not not see this in description so don't buy if you need it for a rolling code device

Easy to set up (and there's plenty on the web to help) and works fine. It sometimes takes a little persistence to make it work but no more than the original. Recommended.
