Be aware that the diff locks work very much like synchros in the gearbox. 
Ie they won't lock (Or unlock) while under much load.
So.. If you have any 'residual driveline windup' the diff lock won't unlock.
Be patient, and wait until they come around.  If you want to sppe up the
process, it sometimes helps to drive in a 'zig-zag' or series of 'esses'
which may unload any wound up torque left in the driveliine.
(Or in otherwords, don't expect the lock to come off, immidiatly after
driving around a sharp corner on pavement. Drive straight ahead for a
while, and it will unlock though)

I hope this makes sense..

Regards!
