Car model and year:
Mercedes Sprinter 906
I only have one key and I want to make a new one.
Cheap tool option:
CGDI MB tool
For the cheaper way you need to know how to remove ezs and read secured Motorola processor, then need to write nec key manual
If you want only the key and cheapest way is use locksmith service.
Benz it not simple key and doing that is very risky if you don’t do it sometime before.
That is my own advice
Also the fastest way by OBD is CGDI MB tool. no need remove anything, all over OBD.
