I finally received my second master key from the dealership for a 2005 endeavor. The 2nd key will lock and unlock the doors but it will not turn the engine over. Every time I try it the immobilizer light goes off. I did try using the 1st master key in the on position and then inserting the 2nd in the on position until the immobilizer light blinks and then reinserting the 2nd key again to try to program it but it does not take. Any suggestions?
