Product attributes:

The retrofitting of the original comfort key / Keyless Go / Keyless Entry is possible on all AUDI A6 / S6 / RS6 4A C8 models of all years of manufacture, all body styles (Avant, allroad, sedan) and all equipment variants.

Please note the current exclusion for vehicles from model year 2024 with installed PR number NI8 (NI8 = Without UNECE CS (R155) and SU (R156) with SFD2-SG). Unfortunately, these models cannot currently be retrofitted. As soon as this is possible, we will inform you here in the product description of this retrofit package.

Installation information:

The external door handles are not changed (these always fit) but the original sensors are installed inside the existing door handles; currently only "blind caps" are installed in all four door handles.

In addition to the two Keyless Go antennas already installed (1x in the center console and 1x in the trunk), a total of 4 antennas are now installed in the vehicle; these two missing antennas for upgrading from KeylessGo to KeylessGo+Entry are located in the doors.

INFO: Antennas are already installed because of the standard function of starting the engine via start button (= Keyless Go).

The existing vehicle keys are already functional and do NOT need to be replaced.

The cable sets run from the comfort control unit (= BCM2, this is located in the trunk) to each door.

Please check the compatibility of the comfort control unit (= control unit address 46), in around 50% of all cases this has to be replaced with a Highline control unit due to the equipment. You are welcome to write to us about this together with the chassis number and the currently installed part number, and we will check this for you.

If a replacement of this comfort control unit is necessary, we can also offer it to you under article number: 10771.
