Crafter

Sombody today moved my mothers car, she normally does not let any one drive it but was only accross the bowling green car park! They said they knew what they were doing and the consequence of their actions is we can no longer select park with the gear lever, is it like there is something blocking it. He even removed the keys without the vehicle being in park. I did not think this was possible. I think the person has just forced the car into gear without either pressing the foot brake or pushing the knob on the gever lever, but the big question is does anyone know what is wrong and how do we repair it? Anyone any ideas of a way forwards? thank you
