My sons 93 corolla will not open with the key. All four doors will not open nor the trunk.
Sounds like somebody replaced the lock cylinder for the ignition. That would mean that the key for the doors and trunk is coded differently. If you can get the trunk open remove the lock cylinder and look for the key code stamped on the outside of the housing. You can have a new key made, using this code, by a locksmith. HTH. -Jim
