After renew eis i could write vin in all eis what i have.

Renew eis dont erase mileage. So if you renew eis and program to difrent car mileage stay in eis .
With keys work with almost all. Dont work with BE keys from MBE. I have 4 keys from no immo and read them only in 50%.

If your work on table, make sure you have above 12,5v, any thing less calculation for password failed.
