The switches inside still continue to work.

I got the lock button to function on the key fob but not unlock

Wired the 451m according to what was listed in the manual :

"wiring diagram c directly wired reversing polarity switch circuits."

I chose to wire the banvie as a negative trigger

As far as I understand it that's how it should be set up.but it doesn't unlock...
