4 часа??? Жесть..
Диагноста хорошего у вас нет.

Блок КОС который хранит ключи записал ошибку о том что принял неправильный сигнал ключа.

Скорее всего неисправен ключ.
Диагност если бы умел то попробовал прописать ключи заново. Хотя может он и пробовал и поэтому порекомендовал замену блока.
Хотя если вы ему оба ключа не отдавали и они оба заводят машину то не пробовал.

Code No.B1A08 Keyless/KOS key1 performance
Code No.B1A09 Keyless/KOS key2 performance
Code No.B1A0A Keyless/KOS key3 performance
Code No.B1A0B Keyless/KOS key4 performance


caution When replacing the ECU, always check that the communication circuit is normal.
DIAGNOSTIC FUNCTION


The mechanism which automatically changes a code for lock/unlock each time a lock operation is performed is referred to as a rolling code. If KOS-ECU receives wrong signal (out of synchronisation of a rolling code) from the keyless operation key, KOS-ECU memorises the diagnosis code No. B1A08, B1A09, B1A0A or B1A0B.
JUDGMENT CRITERIA



B1A08: If the difference between the rolling code for the keyless operation key 1 (the first keyless operation key registered with KOS-ECU) and that memorised by KOS-ECU is large, it is judged as abnormal.
B1A09: If the difference between the rolling code for the keyless operation key 2 (the second keyless operation key registered with KOS-ECU) and that memorised by KOS-ECU is large, it is judged as abnormal.
B1A0A: If the difference between the rolling code for the keyless operation key 3 (the third keyless operation key registered with KOS-ECU) and that memorised by KOS-ECU is large, it is judged as abnormal.
B1A0B: If the difference between the rolling code for the keyless operation key 4 (the fourth keyless operation key registered with KOS-ECU) and that memorised by KOS-ECU is large, it is judged as abnormal.
