Opel Insignia 2008: Anti-Theft System Issues, Key Battery Change & New Battery Solutions

Hello.
Has anyone encountered this message? Check the anti-theft system ?? I mention that first it happened with one key, I changed the batteries, but unfortunately nothing helped. We started using the second key and for about half a year everything was fine, after which it has been appearing again for two days. Sometimes, after hard trials, I manage to fire, but I do not hide that I am afraid that one day it will not fire.
After suggestions from colleagues from another group, I bought a new battery, but that's not it either.

Make diagnostics, there should be errors.

You've got the sc code card

Does anyone read the OPERATING MANUAL ????????? !!!!!!!!!!
That's where it is described .....
PS: INSIGNIA started coming out since 2009 ... so in the margins of your 9th in VIN is the number "9".

Please do not write stupid because I know which year is the car! In addition, yes, I read the user manual and nowhere is written about it!

Before I asked the question here, I studied the entire Internet, all social groups and nowhere is written about it!

Hi. I had the same problem with my Astra J5, I also found nothing on the internet, all the ideas and suggestions from forum members helped nothing, and none of the car repair shops
in my area didn't undertake the repair, while there was one workshop further afield, however, after the stories of its owner (scams) I started to dig into the subject myself.
Based on reading various forum members and a godson of a car mechanic, I came to the conclusion that no one had mentioned the immobiliser coil located at the ignition. I took apart the relevant part at the steering wheel (it's quite difficult, there's a description on YouTube) and replaced the coil itself, the module with the chip has to stay as the
computer of the car "sees" it through the bus and with another module will show an error. It turned out that the resistance of my car's coil and a good coil (easy to buy on Allegro, I gave £28)
differed by about 1 ohm. After fitting the coil I bought, everything works fine, the message disappeared too.
Maybe someone can help me with my story related to this fault and tell me how to deal with the message "too low coolant level", the level in the expansion tank is ok, I also replaced the coolant level sensor, but it did not help, maybe you need to delete the error counter, only how to do it without a computer, greetings.
