Basically you will have to determine whether the CDs are mechanically jammed or there is something amiss with the electronic control system with your player.If the CD is mechanically jammed , then the player will have to be dismantled to gain access to the CDs. Alternatively the CD player may just require "rebooting"...so if you have the code then remove the fuse,(or battery) for 5 minutes , replace , enter the code(s) then hopefully it should reset itself.
