your problem could be related to more then one issue

In order to know if the problem is in the Key motor or the comunication board to PQC , i need you to MAP the non working keys

each key on each unit - is it working or not ?
are the keys FLASHING on PQC ?

Once you tell me this info i can determone if it is motors or electronics

If you put a good motor in the spot where a motor was not working and the key starts working, the motors are burned out. You can order new motors from http://grapha.mybigcommerce.com/
