The Remote TX278 4-button key chain duplicating learning remote control copies from existing remotes to duplicate the signal. With code switch and fixed code types once it has learned the signal no additional programming would be needed. With rolling code type remote once it has learned the signal it would then have to be learned by the opener before it would work. Since this universal duplicating learning remote control can copy from different formats (code switch, fixed code and rolling code remotes) it has more flexibility over many other models of learning remotes that are typically limited to either fixed code or rolling code or have specific operating frequency range. With the Remote JH-TX278 remote you can combine up to four devices into one compact remote control that can be uses as a key chain remote or secured to the vehicle using the included adhesive hook and loop fastener. The Remote JH-TX278 also features a 8 second time out function that stops the remote from transmitting after 8 second in case a button is accidentally held down and preserves battery. Since each button is independently programmable you are not limited to the brand or types of remote that it can copy from as long as it is within the frequency range range of 280MHz to 870MHz. Comes with remote, key chain attachment, self adhesive mounting pads, battery and programming instructions.
