If you have the KR55 Keymaker device you can upgrade your set to the WSP Keymaker which allows you to make new keys on the following car models:
- 2003-2007 Sprinter W901-W902-W903-W904-W905
The update allows you to make a new key in both cases: when you have one working key and when all the keys are lost.
- WSP software
- 2 new flip keys for Sprinter W901-W905
When you paid for updates, write an email to firstname.lastname@example.org and enter the order number and the SN number of your device (see manual below) to obtain the activation files.
