I absolutely concur with "deanyel". My ignition went out in '04 on my 92 400E. There is no warning it just freezes or perhaps those times when I thought that the wheel was off center and I held it to turn the key were warnings...hind sight is 20/20. But yeah, just go to the stealer and order the tumbler. May as well order a new one for your drivers door as well. Its probably not far behind...dont ask me how I know
