ignition controlled locking

I have install a DSI 7000 on a 1998 Dodge Durango the remote works the locks when armed and sisarmed as normal. But the ignition control is not working, the locks will not lock when the key is turned on, but when you turn the key off the locks try to unlock, I have discovered that if the key is left in the switch the locks will not lock, There is some kind of circut in the durango that prevents the locks from locking when the key is in the switch, does anyone know a way around this

No its not that, You can have all the doors open with the key out and the locks will lock, but the loks will not lock if the key is in the ingition, so when the key is turned on the ingition controled auto locking will not work, there is something with the Dodge Durango that will not allow the locks to lock with the key in the ingition, I need to find out how to bypass this
