Cloning Remote Control Keychain, Replacement Garage Door Electric Gate, Duplicates and Replaces Original Factory Remote Controls for Vehicle Central Locking Systems, Electronic Garage Doors (KT01-4)

A pesar que la frecuencia es la misma, no funciona ninguno...

This remote uses 433MHz and older garage door openers use 315 to 390 MHz. I am not sure if that's the issue on why I was not able to clone the remote.

All 4 of these remotes work well at opening the Ghost Controls gate and have similar range to the original Ghost controls remote.Details: I purchased 4 of these remotes to see if they would work with the Ghost Controls gate I installed at my parents farm. I also dabble in radio electronics so I checked the frequency output of the original Ghost Controls remote and compared it to the 4 replacement remotes. I used a high end spectrum analyzer to analyze the center of the transmit frequency and found that the original Ghost remote was broadcasting at 433.991MHz. I then programmed the 4 replacement remotes and verified on the spectrum analyzer the playback center frequencies of each of the 4 remotes. Interestingly, each remote had a slightly different center frequency and none of them, including the original, were exactly centered on 433.92 MHz. The 4 learning remotes meausured the following center frequencies: 433.771, 433.815, 433.885, and 433.942 MHz . I was using a uncalibrated wideband antenna located about 3 meters away from the remotes when performing these measurements. Roughly speaking, the original Ghost Controls remote was about 30% higher power than the 4 replacement remotes. Finally, I brought the remotes out to the gate for testing. All 4 of the replacement remotes reliably opened the gate from over 500 feet away. I could not tell any difference in performance/range despite the original remote having slightly higher output power.

Update:After one week later, both remotes stop working even with new battery replaced.It works great with my Topens PW502 gate opener, only took a few minutes to set it up.

Got these to replace some really old remotes that were the same we got with the house. I had replaced batterys on them, but they were losing range, got these new ones in a 4 pack and wow, range is back to really far away again, very easy to use and program and worked well with strong battery included. Very happy.

No way to program them, I followed the instructions precisely and they just blinked and did nothing more.

had an issue with a weak battery or something. one paired up just fine and the other looked like it would but looked like it was weak. when trying to see if it would work ... it didn't.this was pairing to a tennis ball machine slinger bag.Got a replacement and the other one worked just fine after cleariingTo clear:1) hold A + B, let it light up.2) while still holding A, press B 3 times and the light will flash quick3) I did it again but holding B.To pair:1) press the device and hold it down2) get remote close and hold the button you want to pair (I've only use A button).When pressing the Button it should light up solid and NOT bling. if blinking or weak it didn't pair correctly if you press it after pairing.

Got pretty much what was expected, and they even came with batteries. Only issue I ran into was I am trying to program these to an arduino compatible rf receiver, and the receiver would not register these remotes even with the receiver learn setting enabled... What I had to do first was program these remotes to the remote that originally came with the Arduino receiver (had to find an odd size battery for that remote, as well, which took a an hour or so of driving around to find a store that stocked it since it was getting late at night already), and then they finally worked with the receiver.I'm assuming that these remotes came sent blank programmed, where I thought they were already programmed on their own rolling code algorithm, where you also had the option of reprogramming them to another compatible code transmitter... This is potentially an issue for me as I was planning on making a few sets of these with unique remotes that could not control each different Arduino setup, so will need to figure this next step.That being said, these remotes do in fact work, are the size, form, and design factor I was looking for, and have adequate range. (Tested range was through 1 thin aluminum plate (box enclosing the Arduino receiver), 2 wooden walls and approximately 25 feet distance. This was without the receiver attena attached to the receiver chip (has to be soldered). Have not tested farther as these I'm assuming would cover all my intended purposes.If can figure out how to program unique codes to these, will likely be getting more for multiple projects.

Not one of these remotes worked! What a complete and utter waste of money. They simply would not program and we knew how to program them having used them in the past. I would have left zero stars but sadly I wasn’t able to!

I bought them and followed all instructions.They do work and copy remote controls but not rolling codes as they claim.The control I tried to copy was even featured in there video. It does copy it according to the instructions but does not work in use.You can not return these remotes as the company has a no return policy.I pointed out to Amazon that in the UK all things sold by mail order are covered by distance selling regulations and give you a right to return for any reason for 14 days from delivery.They gave me a refund.If you have any trouble with these just call amazon customer service and quote distance selling regulations.They will send you a refund straight away.

Worked perfectly as stated. Configuration was easy although the instruction manual can be improved upon. Works with rolling code and with long range.

Cloned all 4 remote's easy but not testing for 2 weeks 🤞

The media could not be loaded.  I got one in blue and one in silver without a keyring clip, not a massive issue but just a bit odd.The big issue is that they simply do not work.I've paired them 7 or 8 times now, they take about 2 minutes of fiddling about trying to get them to pick up a signal and when they do, they just don't work haha.As you can see in the video, the remote is paired but doesn't actually do anything
