Won’t stay cranked

Do you mean ignition ,, like coil, wires etc.... or do you mean key and tumbler? If it was the key and tumbler than you need to reprogram your key ... this is a long- shot but sometimes works /// hold the plastic side of your old key as close to the key slot as possible beside the new key ,,, try to start ,, if it starts than follow the on=line instructions on how to program your new key

Thanks man
