What about customs?
We are not responsible for any custom fees once the items have shipped. By purchasing our products, you consent that one or more packages may be shipped to you and may get custom fees when they arrive to your country.

Keychains and module work. The first time, the keychains were connected, but the mode of operation could not be changed. Reset by pressing the button on the board 8 times. For that, once pressed the button on the relay board until the LED was lit and even then pressed the button on the key fob once. You can also change the modes by pressing the button on the relay board twice or times. Everything works. Tied two keychains in this way.

Thank you for your detailed feedback! We’re glad the keychains and module are working as expected. Your explanation of resetting and pairing modes will surely help others. Enjoy your project! 😊
