The control unit is only installed together with the
Advanced Key option.
It is located at the right of the dash panel, behind
the glove compartment.
It evaluates the signals from the outer door handle
sensors and then activates the antennae for access
and start authorisation.
The capacity-based operating sensors in the outer
door handle detect any contact on the handle and
send a signal shortly afterwards to the antenna
read-in unit for keyless access authorisation.
The antenna read-in unit evaluates the signal and
then sends a query to the vehicle key via the
antennae for access and start authorisation.
The sensors switch off after approx. 80 hours once
the vehicle is locked or after 20 actuations without
an authorised key.
