Hello, what could be the reason why my kessy not working, it sometimes works and sometimes not, only the problem is the door handles, trunk and start button is working. I have change the key fob batteries and also the car battery also have changed last winter. But what its weird is that there is no fault codes at all... I also changed the driver door wiring because there was cracks. Sometimes in radio screen it show that 12v battery low, when there is still 12.3v when ignition is on, could it be the reason that it disables the kessy system?

Hello! I check my driver door wiring and there was many wires which insulation was cracked. Is it possible that it can cause some fault that car thinks it drains power somewhere? I also code a battery again so lets see if the battery low message disappears

I change it just as a precaution

Yes, the old battery was agm and it coded to fleece

How about this part, does it need coding because i changed it?

Okay thank you very much! I'll try that

Here is info

No, i have to buy that kind of voltmeter to 12v socket. When i change the battery control module and i think it dont work it should, i recharge the old battery and code serial number from 1111111111 to 1111111112. And then i change the battery and code the serial number back to 1111111111. What lf it now thinks there is old battery again, is it better to change it to 1111111113

I have coded it

Hello, my infortqinment screen shows sometimes that 12v battery low. I just changed new battery and battery control module which is in ground cable. Also kessy not working and soc shows 0% Then if i open the driver door and close it, then kessy is working and soc shows 90% Is is possible that driver door wiring is broken or something. There is pics what are the only trouble codes
