stereo double din turns on and works when battery is just connected but not any other time periodically turns on while driving, any ideas? No fuses are blown and every time the battery gets unplugged and replugged it works just fine until the car is shut off, btw I do have an ignition cylinder and passlock issue occasionally because my key doesn't have the chip like the original key for it, I had a spare remake made cause I lost my keys out of town awhile back, could the passlock possibly be the culprit? Or is it most likely a wiring connection issue?

 

Check the remote wire would be my first guess, then make sure the rest of the radio connections are correct.
