If you can't retrieved the plates, the best and safest way to get a car transporter to transport it or tow it between locations. We remind you that you can withdraw license plates for a car (if they have not been cut off by police), even if it does not have a valid inspection, if it is in a normal condition. The owner then signs a statement to this effect and brings the car to inspection immediately after the numbers were put on. Further information is available here.
