What is difference of OBD 48 Copy and 96 BIT 48 Copy? Why do you need both?

OBD 48 copy needs use a data collector via OBD way to collect car data with OBD device(like VVDI2)…it can program new keys when all keys are lost but needs a OBD device that is able to read data.

As for a transponder 96bit, it’s used when you have an original 48 key; that is, you can copy a new key from an original key, without collection with the OBD and car. But attention please, here you must have the original 48 key.
