The other morning, my key would not turn in the ignition...after wiggling the key a few times, i managed to get the key to turn when I insert the key at a certain angle. The car started, however, the next day, The same thing happened with the key not turning, put it in at a certain angle, but the car engine would not turn over, and it cranked weird as well, sounding like the battery was dying or something. Should I replace the ignition cyliner or the switch?
