My Controll A Door can be activated by another item that emits a 433MHz frequency. Is it possible to upgrade the control motor with a new micro chip with another frequency instead of replacing the whole unit as it works perfectly.

  • How old is the opener? Pretty much in the last couple decades, all openers are using technology that makes it very difficult to accidentally (or maliciously) open the door without a programmed/recognized remote. What 'other electronic devices' can open the door? – gregmac Sep 27 '14 at 19:44
