How do I unlock the ignition with the electronic key or transformer key? I pulled it out and put in back into the ignition but it will not unlock. Cannot find anything clear in the manual. Thank you.

i have the same problem on my c200 2001 kompressor. it take some times to trigger infra red & unlock the steering. anybody have same experience like this... pls share with us. tq

you may wanna try a new key

Have you checked the battery in your key?

Most likely the key itself that is the problem as the man before said Have you tried the spare key?
