So, we lost the original key to my 85 RX7... We got some made down at the Mazda dealer here in SA. Got in the doors, got in the trunk, new keys wouldn't turn the ignition, so we assume that the ignition assembly is original, we ripped out the tumbler quite forcefully but the ignition switch seems to be fine. So at the moment im able to lock/unlock, but I'm starting with a screwdriver. I'm just trying to see if there is any way to just replace the tumbler? Anyone have a link to a website or something? :/ I'm assuming if all else fails i will have to replace the locks and the ignition/tumbler with a new set for new keys, but I would rather keep the old keys. Hell I don't care if any key can start it, I just get very nervous starting it with the screwdriver.

 

The ignition lock cylinder has to be replaced as a unit. Their is no replacement tumblers such as you see in early American cars.

If your new key did not fit the ignition switch then either the door locks had been changed or the ignition switch had been changed before as they are all keyed alike from the factory.

New full lock sets are no longer available for our cars. You can place a WTB thread to see if anyone has a complete lock set with keys for your car or get a used ignition lock cylinder and have it keyed the same as your doors.


Here is the link for a new ignition lock-
