تم تجربته على جميع الانواع ولم يعمل الا مع نوع واحد فقط

Bought these to replace a worn out fob. The first one lasted 9 months of use probably 20 or more times every day on an overloaded keyring with loads of heavy keys and other fobs. They get thrown around and knocked about in my pocket so for such a low price, they're perfect. The instructions are small as others have mentioned but there's a photo of the instructions on the listing, easy to follow, they take two minutes to set up.Probably not compatible with rolling codes but fine for what they are. They're cheap, last nine months each, probably not worth changing the batteries if they get abused like mine but they are what they are. Will buy again.

I agree with the other comments that the instructions are very small.I can program buttons A,C and D, the blue LED flashes quickly when one of these buttons is pressed, but with the B button when pressed the blue LED flashes twice after a few seconds and then remains off. This happens on both the key fobs I have.I have tried.1) Clearing the codes by pressing both the A and B buttons.2) Removing the battery for a few seconds.Is this a "special" feature of the B button.Any ideas !Found it , press the the C and D buttons to clear...

I purchased this as a spare/backup for a garage door remote control. The instructions are a little small in the package so I referred to comments from another review. The device wouldn't reset initially so I removed the cell by taking the back off which is easy to do but a small jewellers screwdriver is required. It then reset and cloned the original fine. The range is better than the original and the device has a nice thumb guard to prevent accidental operation. Good value for money product that works well.

I purchased a light box from China and guessed the remote was RF (radio frequency) rather than IR (infra red) as 2 IR remotes I had didn't copy anything. The Chinese supplier never got back to me regarding a possible frequency, so I purchased this item with a frequency range. Programming 4 buttons took about 20 sec:1) Press on the cloning remote A + B simultaneously: an LED (the only one on the cloning remote) will flash;2) Keep pressing button A (do not release this), but do release button B and then press this button B 3 times: the LED will flash again;3) You can now release both buttons on the cloning remote if you haven't already done so;4) Get the remote to be copied, place it close to the cloning remote (instruction say less than 10mm (1cm or 1/3 inch) and continually press the button to be copied;5) On the cloning remote, simultaneously continually press the button you want the old button copied to (I began this step 5) after step 4), in case this makes a difference): the LED will flash first intermittently and then almost constantly (with very rapid flashing) when the code has been copied;6) Release the buttons (I released the new cloning button first, followed by the old button, in case this makes a difference).7) If you think you've mucked it up or you start and don't finish copying at least one of the buttons, the cloning remote appears to need resetting. Do this by pressing both buttons C and D together: the LED will flash and the cloning remote will have been reset to normal operating mode, with any saved buttons still saved.I don't have experience with garage doors or similar but the couple of RF cloning remotes I received have worked well for me with an RF remote control device and were at a great price.

Bought 2 of these to control the security gates at our new flat. Very quick to setup. Seem well made. I like the sliding button cover and they work as expected
