Is your unlock wire connected directly to the lt.GREEN/ black wire? It sounds like you must have the unlock setup like this: pin 85 to your unlock output from the alarm, pin 86 to 12v+, pin 30 and 87a to either side of the cut lt.GREEN/ black wire, and pin 87 to nothing. If you have your setup just like this, you may need to use a relay for the unlock pulse: so then put pin 85 to unlock output, pin 86 to 12v+, pin 30 to the lt.GREEN/ black wire, pin 87a to nothing and pin 87 to ground.

try using a relay for the unlock like I mentioned above, that is all I can think of. make sure when you pulse the wire with ground that it unlocks.
