From the other thread - Help programming RKE transmitter for 2016
After doing some research, the locksmith told me that this key apparently does not have the proximity sensor found in our original keys
This seems to likely be the case. I'm taking a shot in the dark with a different key/remote that has not been discussed (costs $30, I'm on the hook for 20% restocking + shipping ($10) if it doesn't work). I have two working keys already, but I'd like to solve this puzzle, and having another spare wouldn't hurt.
If you're someone who is ready to crack and go to the dealer, hang on for a week if possible, I should have the remote key Sat or Mon,(Edit, I just found out the seller shipped via DHL..... so it's going to be sometime next week.... probably later in the week) and I'll post whether or not it was successful (and details if it is successful).
