ok today my key is stuck in the ignition and got stuck. ive tried the powder graphite and some white grease and even lubricant worked before for a short period of time but now it had gone worse! So i went to see a mechanic they say for a 323,000 KM is it normal or possible that the ignition might be stuck. He suggested me to replace the key ignition cylinder, now i need to know if i replace it do i need to change anything in ECU or reprogramme it whatsoever?
