Towing w/Tiptronic - 2004 Boxster S

[wroot]

Can anyone tell me how to get the car into neutral when it has locked up? I've had a problem with the central locking mechanism failing to disengage when they key is put into the ignition. The key won't turn, the wheel won't turn and the transmission lever will not move out of park. Jerking the wheel from side to side usually works, but not this time.

I have already replaced the ignition switch with the new model. That worked for about six months, but now the car is refusing to unlock again. I want to have it towed to the dealer so he can diagnose it when it is malfunctioning, but I can't figure out how to get it into neutral so it can be pulled onto the flatbed. I've been through the owner's manual twice and can't find any instructions how to do this. Does anyone know how to do it?

Thanks very much.
