I am having a heck of time getting my 73' door keyed lock installed correctly. I cannot get the key out when it is locked and tried rotating the barrel in millimeter increments and still can't get the key out. There has to be a trick I am missing. Instructions say to rotate the barrel a quarter turn if the key doesn't come out when locked. Tried that. I tried it with the key inserted and with the key out (put back in to lock). Anyone have any suggestions? It is a OEM Toyota lock.
