Technical Immobilizer - does not start

Hello, I have a Fiat Stilo 1.4. 16V 70kw.
I can't start it. It gives me the error "Check vehicle protection system". My immobilizer light is on (car with a lock). Once I came to the car, tried to start it and the battery was low. I took the battery out, charged it, put it back in and have had this problem ever since. The car won't even start, I turn the key and nothing happens. I tried starting via cables, power bank and nothing. I thought the problem would be with the batteries, but apparently it's not. I called the technician and he told me that there was probably a problem in the control unit, but after about three days I came to the car and it started normally, as if nothing had happened. I turned it off, tried to start it again and it wouldn't start again.
Sometimes when I try to start and take the key out of the ignition, the dash lights start flashing. About 7 seconds and then everything goes out. Has anyone encountered the same problem?
