2012 hyundai elantra

Hey everyone; i installed a remote car starter in a 2012 Hyundai Elantra a couple of weeks back and no bypass was needed, i hooked up the door locks with the aftermarket starter too. My question is, sometimes not all the time the doors wont unlock while vehicle is remote started, now when i say they wont unlock i mean when i lock the doors with the aftermarket remote starter and remote start it a couple hours later then hit unlock on the remote starter remote they will not unlock. I know if you use the factory remote & lock the doors and then try to unlock the doors with the remote starter remote they will not unlock. This puzzles me because this isnt a constant issue and it comes and goes, anyone ever run into this situation? Should i program the doors to unlock with a double pulse instead of a single pulse? You think that would change it? Im scratching my head here because all the wires are corrected right and the door lock color is:pink/black and the unlock is:yellow/black near fuse box, white 24 pin plug that's what it states. Any information would be helpful, thanks guys!!!Thanks, Bri

You could try it this way ( info from Omega ) :

 Lock        PINK\BLACK (- LOCK), BROWN (LOCK DETECT)   DASH FUSE BOX WHITE 24 PIN CONN, PINS 23 & 6

 Unlock    GREEN (-)       DASH FUSE BOX WHITE 24 PIN CONN, PIN 16 See diagram #240

Thanks Kreg- Looks like this might be the problem, now do you think this would refer to the 2012-2013 Hyundais?Thanks, Bri

The above info was listed for the 2012 Hyundai Elantra.Soldering is fun!

Kreg is right, you need to connect the detention wire. Be sure to diode isolate them.
