How do you program a 2001 Toyota Sienna key with a transponder chip?

Answer 1

To program a transponder key for a 2001 Toyota Sienna, you'll need two working keys. Insert the first key into the ignition and turn it to the "On" position without starting the engine, then back to "Off." Remove the key, insert the second key, and repeat the process. After programming, the new key should start the vehicle. If you don't have two keys, you may need to visit a dealership or a locksmith with the appropriate equipment.
