I unlocked the front door with my key (Euro lock??) whilst a key was (unknowingly) in the barrel on the other side. Got in, and now the keys are out of sync. I can only remove both with the lock undone. If I lock the door the key will not rotate far enough to be removed. How can I undo this?!
Lock barrel out of sync?, I think possible it's broken as opposed to out of sync. Remove the cylinder and check it out of the mechanism, if it works as it should then it could be your locking mech, try it and come back with what it's doing... B J
"If I lock the door the key will not rotate far enough to be removed." Normally, after locking, you will need to turn the key back a bit to remove! Mr. HandyAndy - Really
Finally got round to this... The cylinder is out and the arm (?) that rotates is 180 degrees. I can't see how to adjust this, so I think a new cylinder is required.
If you were going to attempt to fix it, I would try to do what you did in the first place. Put both keys in, turn any one key only, to get it to the full turn(try not to let the other key turn). Then remove the key that you turned. Turn the other key full one way then full back, and remove it. Maybe it's reset. Maybe not. Mr. HandyAndy - Really
Hi Andy, I've tried to rotate one key whilst holding the other rigid, but it isn't happening! No problem, I've learnt a little about locks anyway!
Good u tube video from locksmart locksmiths, showing how to rectify it by removing c clip from one side of the arm, with key in and pulling barrel out very slightly (about 2 mm) and rotating arm to correct position. Push cylinder back in and refit clip. Worked for me, just be careful not to retract cylinder too far or you will not get it back together.
