How much did the ecu cost? Mine occurred in the hot afternoon. The car suddenly can not start for the first time after years.
400+. But no point. Nothing solved after ECU change. For me u change because proton centre told me my knock sensor code could be also ECU problem. Never went back to that proton edar again.
Anyway I suspect battery getting weak and that somehow triggered the issue. Incidence was a lot less after I change battery. How old is your car battery?

This is a secondhand car, when I gt the car, the key ady gt problem. Sometimes, when I press the button hard. I still cannot open the door. Before the car was unable to start, I didn't drop the key. Maybe I placed it in my tight pocket that caused the problem?
It's the sponge that pressing on unlock button getting flattened by long term pressing it. Try open it up, add some paper bits in between your button overlay and the button on the chip.
If you hardly drop your keys, mostly the immobilizer chip is not damaged. Original immobilizer chip of Persona is plastic type, not glass tube type. Even drop also won't be so easy to spoil.
