same thingy happened to my R33,
open up the drivers side door, check all the rods, there should be a 2 rods going into the actuator, then follow the rods until they seperate, should be this little screw thing holding both of them together, push the to rods hard together and tighten the screw, then try your alarm or central locking, after that it should work, thats what happened to mine
could be same situation as yours but just give it a try
