Good Afternoon, my name is \*\*\*\*\* \*\*\*\*\* ill be helping you, so sorry to hear about the issues here on the Yukon. I know how frustrating it can be to deal with crank no starts. If the battery was disconnected i agree that we are likely dealing with a security system issue. On this model you can reset it by turning the key to the on position and letting it sit there for 10 minutes and then turn it off for 30 seconds. repeat that process two more times. If the vehicle still will not start up you will need a locksmith to re-program the key to the vehicle and reset the security system that way.
