I installed viper 791vx but the door lock/unlock didn't work for some reason.

What color wire are you using for the unlock/lock feature?
What color wire and where are you running to?

Read the book and reprogram it!

what kind of car?

 

[hybrid90accord]

it should be the blue/green wires

 

[aaa12345]

running the black/white to the door lock - and the black/red to door lock +

on the viper 791xv

green(-)lock (+)unlock
Blue(+)unlock (-) lock

those should be the two pin wires that plug into the side of the alarm brain.
