2001 Mercedes-Benz E320 Q&A

2001 Mercedes-Benz E320 Question: Key sticks, after a while is ok only after we have a conversation..

Smart key sticks in ignition, is there a solution to this or do I have to replace keys, ignition etc. Would a electrical lubricant/cleaner help? Thanks -
Answer 1
first line of diagnosis is to have multiple keys ,test each key for a day ,or unless it happens right away ,then probably want to take it in and narrow it down to an EIS electronic ignition switch ,or it could just be low voltage in the vehicle , hope this helps -

Thanks for the info... I sprayed the smart key with a electrical lubricant and the key isn't sticking, at times it seem to want to but with a little preasure it turns. -
