2017 Lacrosse theft lock out
 

I was trying things with RKE entry, Key only entry. I activated the theft lock out and now the car will not start. DCI is blank. How to reset. I have the RKE and it will unlock the doors, but nut all start of engine. Can anyone advise?????

Did you check to see what your owner's manual says to do?

Of course, Hanky.

Sorry about that, What if you checked with your nearest Buick dealership? A lot of times a salesman/woman will have the answer, worth cheking.

They say it is obviously broken and want to tow it to the dealership service dept. ($$$$$) It is not broken, just locked out., Somewhere there has to be a compilation of what to do with this sort of issue.
The car is 2+ years old and the service "secrets" have got to be available somewhere.. Oh well, I'll keep trying. I will share any info I learn along the way.

OK. Sit in car with RKE In hand. press and hold the Start/Stop button in for 1 Minute (60 Sec.). Release button, put the RKE into the slot provided in the seat console.
Put foo on brake pedal, press stop start/Stop button. Car will start. DIC is enabled and life is good again.
I can't believe now-one else had this info. good luck to all. Regards, Richard.
