Greetings!

A body shop called us for a no-start condition after they switched out the switch housing/unit start stop (part GRY7-67-5S0E) on a 2020 Mazda. The original part starts the vehicle just fine, but the customer gets an intermittent key warning due to the FOB sensor in the vehicle. 

I have dug around a bit, but I can't find anything documentation that suggests this is either the immobilizer or a programmable module that would prevent the vehicle from starting. 

Does anyone have experience with this particular part?

Thanks in advance!

Mitchell states that the start/stop unit needs programmed after replacement as it's part of the immobilizer system. It does appear this part holds the key codes for the immo.
