The lock out problem with the fichet may be caused ,because over the years with vibration on the door the actual screws that hold the lock ,to the main lock casing have come loose.
in effect have separated,the lock may work ,but its not engaging the cam and throwing the bolt.
this may seem as if the lock is being blocked by a relocker,but in actual fact its just spinning.
try the lock for play,then gently tap the lock back to reseat it,then try and unlock it.
strip it ,and retighten and use a bit of lock tight on the screws,to stop it happing again.
hope this helps
