I just looked at a radio all already to re-enter code. The vehicle was lent out and when returned the radio came back with 1000 on the display. If you power it off and back on, it displays SAFE for a moment and then goes right to 1000 without user intervention.
Could someone have pressed those two buttons and held them until the working radio went to SAFE mode and then to enter code mode? Any other reasons this could have happened?
This is a first for me. I have the owner trying to contact the dealer, or previous owner, for the code since she recently purchased this car earlier this year and I could not find the code in usual places like on the radio. No she does not have the original owner's manual.
TIA
