hello... when you attempt to get the display to show "- - - -"... does the radio display LOCK instead?
maybe this info will be helpful if it won't allow you to input the code. (see below)
When the theft-deterrent feature is armed or secure (SEC), the radio can enter the locked state if the power is removed from the radio for a long enough period or if the customer has accidentally entered the wrong number three times. (An error message is displayed after every wrong entry.) When the radio is locked, LOCK appears on the display and all radio functions are disabled. Before another attempt at the correct code can be made, the radio must be On and the display must show LOCK for an hour. After an hour, "- - - -" will appear on the display and the correct code may be entered if it is known. Perform the following steps to retrieve the code to unlock a locked system using a known code.
