BMW key programmer to use: Xtool X100 Pad 3
BMW – auto search and show you what system it has. Manually after the model will also show what kind of system. It’s better to make a copy of the time before making keys after lunch. There is always something to come back to.
Please note that: after obd xpad3 probably will do it too, but it’s better to have a copy in case of failure. Turn on the charger when you’re about to work after noon.
CAS3 or CAS3+?
Will depend on what region or country you are in. You should try determining exactly which CAS either 3 or 3+ Either way. Much safer to remove CAS and program on bench
To avoid Bricking CAS module.
2007 can easily be Cas3+
If you attempt via OBD2 you will have a good chance to brick the CAS module
ALWAYS do these on bench.
The extra 10 minutes is well worth the 5+ hours to recover the CAS module.
