OK I feel like an idiot. The truck does not have a OEM security so I'm using the WHITE/ green for locks through a 315 and 620 ohm resistors. When I ground lock wires with resosrtor installed locks work fine. Now that I hook the RS to the locks and press lock and unlock with remote the doors lock with both signals. So I conntected a relay thinking ground was not good enought and now they only unlock. WHAT AM I MISSING????? I'm connecting a Crimestopper2016 that uses a neg for the lcok wires. This is not my first rodeo. Figured I will add that. posted_image

315 is ok but the other one wont work. 620 ohm? lock is supposed to go through an 820 ohm resistor. that could be the problem.

But when I ground the locks to chasis they lock and unlock just like they are suppose to. I'm puzzled????????

the remote start may not have enough of a ground to provide what is needed. I install DEI systems and most of them come with a 451m relay pack. its 2 relays in one housing that makes the negative locks from the starter trigger relays that provide a direct pulse to ground.

*EDIT*

I reread the post and I have no idea why when you use a relay they only unlock. all I can think of maybe you have the wrong resistors???
