Removed subs/amps, now Key Light is on??

stealth23

Alright my 370 came with sub/amps and all that good stuff installed.

Since Im not into sounds or what not and know nothing about it, I decided to sell it. I sold the subs and amp yesterday. The buyer just checked if the subwoofers worked(which it did) and just unplugged the wires from the amp and the sub. And both of us left happy.

Later in the day, I went to my car, started it and noticed none of the gauges or odometer light came on, except for the KEY light. I plugged my key into the key slot but nothing. and for some reason, I had to hold down the Start car button to turn the car off.

So i thought maybe i had to unplug the power source of the amp, so i went to the battery and removed the wire that use to go into the amp. But that didn't change anything.

Can you guys help me figure out what i need to check or remove. Or if its just the Key its self and needs the battery replaced. Thanks

These are the wire from the amp


The top wire that alone is the one that went to the amp(I traced it)
