Service
The part number is on the key and can be viewed after unfolding the key blade as in Figure 1.

2. Replace keys as indicated by the following instructions:
^ For remote keys with part number 8E0 837 220A, replace all remote keys, not only the faulty ones, using the replacement kit containing two remote keys - see table below for part number information.
