Locked ignition

Thanks for the reply. We were able to turn the steering wheel but the key would still not budge. We tried resetting the electrical system by unhooking the battery and then rehooking it. Initially we got the key to turn, but when we hooked the cables up to jump-start the car, then the key would not turn again. After checking other ideas on the internet, we tried tapping the key with the handle of a screwdriver which did work after many taps. So the key not turning and the incorrect cable connection when initially trying to jump-start the car may have been coincindental. We will check it again today.
