Remote doesn't work, radio/dash lights stay on

[Techbones]

The most likely cause for your dash lights and radio staying on is a faulty ignition switch. The electrical part. It is not turning completely off internally even though you have turned the key to off and taken it out off the ignition. This would also cause the "gong" to sound when opening the door because the car still thinks the key is in the ignition. This is a common problem on 986's and 996's.
