Trying to find a key code location for 89 toyota tercel hatchback one key fits all

Hello

I did a key code search on a 1993 toyota corolla . The key code was located on the passenger front doors lock cylinder (door lock tumbler). You have to disassemble the door panel and remove the lock cylinder from the door to read the tiny numbers on the lever of the lock cylinder..I would recommend calling your local toyota dealer and confirming it is on the lock cylinder before tearing apart the door....You would have to give them the code to get a new key cut. hope this info helps..
