Sometimes these batteries are shelved a long time before being purchased and loose voltage over time, that's just a fact of life.
Since you did not have these issues before the battery change, it is the FOB battery causing it, no gremlins have attacked your car!
It is possible to get a brand new battery that is below voltage the CR2032 requirement, which is labeled as 3V but a brand new 2032 battery is usually 3.30V and an actual 3.00v is borderline and not good, lower than 3v will malfunction in the FOB. So take it back apart and check the battery voltage with a multi meter you want above 3v anywhere from 3.05 ~ 3.30v will be good, with the 3.30 lasting a lot longer. Ry
