Remove Key message. Won't start.

When I insert key, I get a "Remove Key" prompt in instrument panel LCD.
When I turn key, nothing happens, no solenoid, no starter, nothing.

What gives ?

Thanks

Do you have another key? Try it first- may have a bad key- common problem. E.I.S could be fried also. Try another key first

Get the error message if I try to start with driver door open. Doh!!!
