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*4)

I wanted to use these for extra garage door openers. None of them would mirror my current openers. Unable to use, so unable to provide factual feedback on the functionality of these.

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.

La verda lonprove porque se veia muy bueno cuando lo vi pero ya que lo conpre y prove no me funciono trade y trade pero simplemente, no me funciono.

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.

I have tried everything to get these devices to copy and nothing works. I have missed my return window for these pieces of junk. Don't buy them!!! If I could give zero stars I would.

all good, works perfect

Veuillez effacer le code de test avant la copieVeuillez appuyer et maintenir enfoncés les premiers seconds boutons de la télécommande (exemple 1). En même temps jusqu'à ce que le voyant clignote rapidement 3 fois, puis relâchez le deuxième bouton de la télécommande et cliquez 3 fois sur le deuxième bouton (notez que ne relâchez pas la première touche pendant ce processus.MÉTHODE DE COPIEAppuyez d'abord et maintenez enfoncé le bouton correspondant de la télécommande en double, comme le bouton A, puis appuyez et maintenez enfoncé le bouton correspondant de la télécommande d'origine (comme le cercle rouge sur l'image) jusqu'à ce que le voyant clignote puis s'allume. . puis appuyez sur la télécommande copiée pour voir si vous pouvez contrôler l'appareil.MODE DE RÉCUPÉRATIONSi vous effacez accidentellement le code de la télécommande de copie, vous pouvez restaurer le code par cette méthode, tout en appuyant et en maintenant enfoncés les deux boutons inférieurs de la commande de suppression, tels que C et D. la récupération est réussie jusqu'à ce que le voyant clignote 3 fois.

Very easy to follow instructions and set them up for 2 different gates.

très bon produit en 2 clic c est fait , envoie très rapide , acheter les yeux fermer (( les deux yeux ))

Reçu mais j’arrive pas à les connecter à mon portail

Programmation bien détaillée, fonctionne parfaitement
