Bought a replacement DEI AVITAL RPN 474L EZSDEI474S REMOTE - 474T 474P 474V which is listed as compatible with my Automate remote start system; however, the programming instructions refer to a "learn" button. I have taken down the remote start and traced all the wiring, but there is no "learn" button anywhere. Is there any way to directly program the new remote using the one working remote that I have?
