The part number

(lock number?) is stamped into the metal on the key.

Toyota will do a new key, but you will have to show them proof of your Id, proof of address, proof of ownership of the car.

Think they also need the reg/chassis number.

Tell them if you want a master key or a valet key

(the valet key does not open as many locks on the car).

Note that some turbo cars did not have remote central locking so even the master key would look like a plain key.
