Having problems with your 2006 Pontiac Montana ?
I have a 2006 pontiac montana and a starting disabled light comes on and the vehicle shuts of when its running , and sometimes it doesnt start on the first try
Most likely the PassKey circuit is going bad. Something to try is to connect a 10 amp battery charger to vehicle and leaving the key in the on position for 10 minutes. at the end of that, turn key off. You are supposed to do this procedure 3 time to relearn the security system. At the end, turn key off, then try to start it. Sometimes it works. Its worth a try. Otherwise you will have to replace it.
