Unfortunately the opposite is not true, where installing an immobilized ECM in a non-immobilizer car eliminates the immobilizer function.

That's what i'm wondering. Can you just purchase a non immobilizer xD ecu and then just remove the immobilizer from the steering wheel and just run a regular tumbler and get new keys cut to match.
Therefore key turns tumbler to activate starter and ignition, no immobilizer to turn off the engine.

The key probably just has an RFID chip in it. The transponder coil is just a length of wire wound around the tumbler that acts as an antenna to "ask" the key what info it has. The transponder ECU converts the wireless signal into control/commands for the ECM, saying "go ahead and crank, it's the right key". |

That makes sense from a design standpoint: our shift-by-wire products have to have a secondary communication system in case the direct line to the TCM fails. It's not always a second CAN line, so the K-line would be a viable backup.

OR.....
Someone could leave all of the immobilizer parts intact, tow the car to the dealership, pay the techs $200 to try their best.....and possibly get answers for the whole community. If they fail, no big deal and you disconnect the ECU. |

Beyond the dealership, it is possible to clear the existing transponder key data from the ECM (so that you can add new keys, as if the ECM is brand new), but that requires opening the ECM an desoldering and reflashing the EEPROM that stores the data.

A fellow dealership tech I know said you should be able to program keys via a locksmith too, I believe they can come to your house so it's worth a shot.
The unknown element here is "IF" the Yaris immobilizer system will communicate properly with the Xd ECM.

They haven't changed anything about it since then, it is still the same procedure for lost keys and the such. We used to do them all the time for customers. Not sure how so many of our customers lost all their keys, but we did lots. Some of the nuances of the newer cars might have changed, but I know we were doing the newer cars, too. Like 2014's new.
Not sure how it would work for a swap like this, but it can probably be finagled. I hope I don't seem like I'm being an ass or anything, I just worked at our Toyota dealership for 11 years. Seven of those were as a manager, and I was one of the ones who would authorize key codes requests and stuff like that, I just wanted to give a broader set of options for dealing with stuff like this. If a dealership is telling you otherwise they are probably just being difficult, or don't have any master techs that have access to complete wipes and reprograms. We would also run into this when people would bring in a valet to try and program a new master key and they would have to do a complete wipe and reprogram it all from scratch. |

I know on the older vehicles that do need a ecm replacement if the master key is lost, they will do a one time free ECU replacement to get new master keys programmed to it. I know as a precaution our techs always just programmed all keys to the vehicle as master keys.
I know when I was at Toyota if there wasn't a replacement documentation for a TSB like the one I linked to, it usually still applied. Toyota was usually really good for stuff like this. I do miss working for them sometimes. They were usually so organized and fantastic to work with. Now chrysler and hyundai, now that's a different story, LoL. |

No, just commuting to work, and I wasn't afraid of using wot to make some passes....and the a/c was running always...so expect an "average" of 30mpg combined.
