Replacing SmartKey batteries
Replacing SmartKey batteries
If the batteries in the SmartKey are
discharged, the vehicle can no longer be
locked or unlocked. It is recommended to
have the batteries replaced at an
authorized Mercedes-Benz Center.
Batteries contain materials that can harm
the environment if disposed of improperly.
Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.
Replacement batteries: Lithium, type
CR 2025 or equivalent.

Remove the mechanical key out of the
SmartKey (
page 357).
Warning!
G
Batteries contain poisonous and corrosive
substances. Therefore keep the batteries
out of reach of children.
If a battery is swallowed, seek medical help
immediately.
Warning!
G
SmartKey batteries contain perchlorate ma-
terial, which may require special handling
and regard for the environment. Check with
your local government’s disposal guidelines.
California residents, see
www.dtsc.ca.gov/HazardousWaste/Per-
chlorate/index.cfm.
i
When inserting the batteries, make sure
they are clean and free of lint.
i
When replacing batteries, always replace
both batteries. The required replacement batter-
ies are available at any Mercedes-Benz Center.
