Default Re: Key stuck after radio install

Headlights on for a few hours is one way to kill a battery. Its always suggested to disconnect power, either battery disconnect or in certain situations, a fuse powering the circuit that's being worked on. Once battery voltage drops below around 10 volts, strange electrical and electronic events can occur. The ignition key not being released may be one of them. As long as this isn't recurring with battery charged, charging while driving, you can probably ignore this one time event. Consider what you did and look back. Did this ever occur before during ownership? And does it reoccur after this project? If not, as days turn into weeks without this reoccurring, this is probably due to battery voltage dropping well below operating range of electronics.
