    Hi fr1,
    it is possible to reprogram or to erase such a device with help of an universal device programmer even if the device has a JTAG lock active. The following 3rd party manufacturers have such universal device programmers: BPM Micro, Elnec or Hi-Lo systems. The same can be done with help of the Altera Programming Unit as well but this product has been obsoleted for a long time.
