HOW do you find the Toyota key code for new keys to replace lost keys?

Late mode Toyota key codes can be determined by VIN. This applies from approx 1990+

Toyota dealer will be able to supply limited ability to provide a code. The vehicle will have to have NEVER had the locks replaced, and they only go back a certain number of years.

Locksmiths subscribed to NASTF can both access the Toyota Factory database, or decode a worn key, or decode a lock with no code at all.

On most Toyota year models; the code number is roll-stamped to the passenger door lock cylinder body. This approach requires removing the lock from the door.

Your Locksmith can handle a situation where the vehicle was rekeyed, where ignition is mismatched from door, as well as older cars that the dealer no longer supports.

No matter which method you use, you will likely be expected to prove ownership of the vehicle, via driver license and either current insurance certificate or registration.

Cars with TRANSPONDER antitheft technology will require locksmith to PROGRAM the keys to the car. Dealerships typically will only do this by towing the vehicle in to do this, while locksmiths use technology that is portable.
