In my Sienna there is an immobilizer circuit embedded in the switch.
I need to replace the tumbler part, but a replacement key has to be programmed with the immobilizer code. I found online the instruction for how to program a blank transponder key for Siennas of later models, but could not find the particular sequence of actions for the XLE. UPDATE: As expected from finding the procedure of later Sienna's and other Toyota cars, there is a simple procedure for registering keys on the model that does not require a shop Scan Tool something like open and close the door 5 times, press the brake paddle 6 times, etc. Unfortunately, I could not find it with online search. #Obdwiz licence key for free#įortunately, a very nice local mechanic was able to print out the procedure, that he found in a subscription based forum site, and gave it to me for free Out of courtesy to his generosity, I cannot post it here. Insert ignition key into ignition lock cylinder. If the registration was complete and system is operating normally when ignition key was removed from ignition lock cylinder, the SECURITY indicator light should flash. If programming additional ignition keys, repeat process starting with step 1.
