Went to the dealer today and got a key cut. Here is the procedure they said would work, insert key in ignition and wait 10 minutes, repeat again, repeat again and then then after the third time the key should be synced and will start the car.
I lost both sets of keys to my 2007 Yukon, I'm heading to the dealer tomorrow to get a new key cut, do I need to do any thing special or should the key work normal.
