I intend to buy key programming devices for mercedes benz but having difficulty in understanding the meaning of some terms used for benz key programming.
So can someone explain these please;
BGA KEY
BE KEY 
NEC KEY
MOTOROLA KEY
Which year and models use these keys.
For now the model years available in my area are between 1995-2010, such as
W202, W203 and rarely W204
W210, W211, and rarely W212
I like to buy VVDI MB but it is pricey for me, may be CGDI as alternative but can CGDI do W202? Never came across a video showing that.
