Door lock?

[firemachine69]

I have an aftermarket door lock/unlock (part of a remote starter get-up).


When I hit the lock button on the remote FOB, headlights flash once signaling a lock. But the doors stay unlocked.

I can lock all the doors by inserting the key in the door and turning it counter-clockwise.

I can also unlock the doors with the unlock button on the FOB.



Any ideas what might be the issue?
