I think I might write this as newPk.startswith('15000')

How about changing this to ...

for newPk, newRecord in newKeyRS:
    if newPk.startswith('15000'):
        print (newPk, newRecord)
    else:
        print '---->', newRecord

It would be very helpful to have a full working example to
play with...
