The radio won't turn on. - 1993 Toyota Corolla

If your radio is just saying "locked" without any numbers after it then just turn on ignition and turn radio on and leave until code appears..... Depending on how many wrong attempts have been made will depend on the wait! Could be minutes or hours...... Just turn on and wait!

The radio and BCM needs read for codes. No reason for the radio not to work after a FOB program. Just a guess, but if the battery power was to low, radio is locked out.

sounds like the rke module (Remote Keyless Entry) module losing power, I hope that helps you out

It is in Theft lock from the loss of power. Contact your local dealer for help getting it unlocked.

Your radio is in theft lockout, you need the security code that came with the owners paperwork new.

battery dead.

check all the battery leads both ends

radio code can only be provided by outlet where radio was purchased. you cannot crack this easily.

I found a paritally blown fuse. When the fuse blew metal pieces ended up partially making contact. After replacing the fuse everything worked great.
