2008 gmc serria

I added some door lock motors to this vehicle. I used two relays and they work fine. The only problem is you cant get out of the truck while the engine is running.( doors programed with ignition lock/unlock) Is there something about the truck from the facotory that im missing(child saftey ect...) Or is there something I need to do diffrently? Never run into this before. Thanks in advance. Brian

Can you draw us a diagram, or at least tell us how you have the relays connected?

How is the door locks being activated and also are they OEM actuators or just aftermarket ones ? You can program out the ignition controlled door locks and if your unit has the speed sense door locks, you can program it for that instead.

Jeff,

   This is a 2008 Gmc Serria with no factory ddor locks.. The factory does have them wired for the Onstar to remotely unlock them.. I just used aftermarket acuators to operate the factory doorlock rod. The customer loves the locks but has to turn the ignition off to exit the vehicle.. I have never run into this before. The relays I added are only wired to the acuators. Is this something that is normal for this vehicle? Thanks for your input. Brian

Is there a way to turn this option off? 

Yes I can turn the ign. Locks off. Why would that make the doors not open though?

some vehicles just don't automatically unlock the door when you pull on the handle from inside the vehicle.

Man, haven't seen you post since 2003.

It's kinda strange to see an independent door lock system can be controlled by the vehicle. The only thing that can explain it is some sort of safety electro-mechanical device that prevent the latch assembly to be unlock.

im no help but let us know the result.

sounds right, if you have igniton controlled door locks turned on they lock when you turn key on and vehicle doesnt automatically unlock an aftermarket actuator when you pull the handle, i would either turn off ignition locks and/or install a switch to lock and unlock or at least unlock the doors, hell just use a momentary(programming button) switch on the unlock relay so he can hit it when he wants doors unlocked while truck is running

Did you add lock unlock switches or did you integrate it into an aftermarket keyless entry/alarm/remote start?

I am going to guess that you added this to an aftermarket system. The vehicle options have absolutely nothing to do with it since it does not have power locks from the factory, if there are no actuators (factory) onstar cannot unlock the doors and they CANNOT operate yours.

If you turn off ignition locks on the unit the doors will not lock when they ignition is cycled so they will not be locked when he tries to get out of the car with it running. That is why they are telling you to turn off ignition locks

If you do not want to cut hole for lock switches why not just do a momentary switch within easy reach under the dash to operate the locks. You can do one for lock and one for unlock, am sure you have some momentary switches laying around or you could buy a rocker switch and mount it under the dash, again, easily assessable.

ok, to make things clearer.....the vehicle locks and when the door handle is pulled the locks do not unlock. RIGHT? this has nothing to do with the aftermarket locks. its the way the FACTORY latch assembly was made.  you do realize there is a lock/unlock button/pull that the customer can move with his/her fingers to exit the vehicle. if this is a problem because of the passenger door...well you should of used a lock kit that was 5 wires and it would of been controlled from the drivers door lock/unlock pull.
