Just happened today, valet pin was programmed in to valet mode, try to unlock it with pin code it locked me out saying wrong pin, so I called a service department, and I was tolded to try this pin code 1926 and it worked they was getting ready to charge me $187 to unlock it.
I hope it works for you whoever need it.

 

This car continues to disappoint, It was a very expensive car!!. Never expected to go through the issues I have had to deal with. It is always doing crazy things, I never know from one day to the next if it's going to run with or without electronics!! Thanks for posting!!
