Notes:
Do not give the master key to an unauthorized person.
We recommend that you carry the flat key with you and
keep it in a safe place (e.g. your wallet) so that it is
always handy. Never leave the flat key in the vehicle.
Obtaining replacement keys
Your vehicle is equipped with a theft deterrent locking
system requiring a special key manufacturing process.
For security reasons, replacement keys can only be
obtained from your authorized Mercedes-Benz Center.
