What is actually in the vehicle may have the same part number, but the firmware on the board is not.
If you have the VIN of the vehicle the used MPX came from, run it. It's probably from a Trail or SR5 with a keyed ignition vs. smart key system.
When looking for replacement MPXs make sure you are running the vin for the vehicle prior to purchase to make sure that MPX is coming from an equivalent vehicle. You can google Toyota Vin decoder and run it that way.

Thanks for the reply, waiting for the seller to respond. For now I have reinstalled the orig MPX. I was poking around with techstream and did find a "configuration" area that read out the MPX part number that appeared to have a few extra digits at the end, presumably indicating a configuration. Have not bothered to reinstall the used replacement MPX to get the techstream readout. In your opinion should a used MPX from a limited with smart key be plug and play in mine?
