ok i have fixed it key now works. done loads to try to get key working. was about to cut key open and replace the 10034a chip with new one , but thought i'd try this first. with ak90 i deleted key from used to unused and was going to drive as normal for few days and then try again, if it didnt work was going to cut key open. something said to me in my mind to look at key status with bmw 1.4. so i did and it said key ok. bingo key now works it reset the random keys so now lets key start the car.
now this error came up with bmw 1.4
F9  NO CAN message (ASC3)
anyone know what it means ?
