This may possibly be an MyKey reminder (Belt-Minder) setting that was programmed in before you bought the car. If you have another set of keys, try using it. If this stops the problem, then it is the admin key and the other one is the M-Key.
Read This and see if it applies to your complaint.
When you find the solution or even a explanation for the cause, please update this thread.
