Toyota 4Runner ECU - Remove, Reflash and Reinstall 93c56 EEPROM to learn new ignition keys.

Here's a run through on how to blank a Toyota ECU so you can learn new ignition keys. If your ECU went bad and are replacing it with a used one or if you've lost all of your keys you'll need to do this or pay the dealer way too much money to do it for you. I would imagine this process will work for many Toyota vehicles from the mid 90's through the mid 00's that uses transponder keys.
