Universal RF remote control duplicator is capable of copying most fixed code or learning codeRF remote controls face to face, and can be used in many circumstances, such as cars, gates, garage door openers, barriers, home security systems, etc. So you will always have a backupremote control.

It's very useful to duplicate original remote transmitters to reduce costs, despite the potentials, a self-learning remote control duplicator is less expensive than original devices, and also permits to integrate several different remotes (both operating at the same frequency, such as 433.92MHz) into one single transmitter. So it is also very convenient.

*It's not suitable for original alarm, 2-way remote control and rolling code remote control.
