I've never seen this problem before...it must be trying to tell me something.
Symptoms:
-The LED display (the one that displays mileage, temp, etc.) is remaining on after the car is off with the key out.
-The lights in the dash that elluminate the symbols around the headlight switch also stay on.
-None of the remote functions on my keys function any longer.
What I've tried:
-Disconnected negative side of battery, reconnected. Problem seemed to go away; keys worked again, dash lights were out, that is, until I turned the ignition switch on and all the problems came back.

Also FYI, my inspection reminder is -700 miles overdue (not sure if this has any bearing on the situation).
Any suggestions...greatly appreciated.
