That’s entirely normal. They check just for a check of CAL/CVN, not that it matches something random on the car. I’ve passed emissions when relocked to stock 4 years running. You don’t need to under any circumstance realign the whole car and all ECUs. Point is that ECUs have a match on CALID/CVN when going into emissions check in CA.
