Remove the postive cable from the battery (makeing sure that all gps ect have been unpluged) touch it to the negtive for 20 sec leaveing the neg hooked to the battery draining all power from the computer, them hook it back up. If this doesnt reset it find a loksmith shop that deals in transponder keys to help or at least point you to a shop that can help..
Hope it wors out for you!

1995 Mercedes C220 alarm issue.
It's normal for the alarm to go off if it was set with the key fob and then unlocked with the metal key. The manual should explain this.
