Ordering a Replacement or Additional Key

Replacement Key
The key replaces an existi ng key, which can then no longer be used. A key can be replaced a
maximum of two times.
Additional Key

ones supplied with the vehicle ca n be programmed for a total of 8 keys. Each additional key can be
replaced twice with a repl acement key.
Register Vehicle as Preset
For each procedure involving drive authorization level 4 (FBS4), the vehicle must first be regi stered
as present in Xentry Diagnostics. This ensures that the vehicle is actually present in the workshop.
Extended Authorization for Key Programming

disabled key track. If this authorization is available, an unprogrammed key can be directly
programmed in the vehicle using Xentry Diagnostics.

Before introducing to the workshop for vehicle registration, both for the on-line
(programming "unprogrammed" key) and the off-line process, the availability of the part for
the unprogrammed FBS4 key must be checked or queried first.
If the unprogrammed FBS4 key is not available, the vehicle's workshop visit should be
rescheduled for a date when it is available.
For safety reasons, after vehicle registration , programming of the key on-line in the
workshop or off-line in Fort Worth Key & Lock, is only possible for a limited period. This is
why, in an off-line case (dependent here on part availability) , the order must be placed
within 24 hours in the logistics ordering system , to ensure that the programming is
conducted promptly in Fort Worth Key & Lock. Once the period has expired , programming
is no longer possible and the vehicle has to be registered again.
If you have not checked the availability of the part, the customer may suffer the
disadvantage of having to visit the workshop at another date. Please check for part
availability, to ensure that this does not happen and that the customer enjoys the best
possible service.
With extended authorization, replacement or additional keys can be programmed on-line in
the vehicle. A training course must be attended before such authorization is granted.
The vehicle is present in the workshop (see the item "Vehicle sign-on procedure") .
Xentry Diagnostics has an on-line connection to the central system . If there is no on-line
connection , contact the Diagnosis User Help Desk.

No diagnostic equipment is required for this.

In the case of a replacement key, the message "Key is being taught in, please wait" may appear in

It is not permitted to hand over the key to the customer without first checking the key works
in the vehicle.
