You can order the part from a southeastern Toyota dealer for $299. The install is not very difficult. My brother purchased from a local dealer here in NC and installed himself. He lives in TN. Nice ride!
I have the keypad on my 21 orp. You can lock with keys in it. You cannot open from the door handle even with the keys laying on the seat. But..... you can start the vehicle from inside when locked with the keypad.
