Difference between MVP and ZED-BULL

A lot of my customers always asked me about MVP key programmer and ZED-BULL key programmer, what is the difference between MVP and ZED-Bull? Which is more suitable to their car? Where can free technical service?

Both MVP and ZED-Bull are very good car key programmer, but they have many differences between its working principle and applicability.
1.MVP copies chip according to car model, while ZED-Bull copies according to chip model. Btw, MVP can not do 4D chips
2. MVP key programmer can still make key even if all of keys lost because MVP interface connects directly to the OBD diagnostic socket to read chip data; ZED-BULL can only write the chip of an old key into a new key or empty key.
3. MVP can read immobilizer pin code, ZED-Bull can not read immobilizer pin code, ZED-Bull can only directly copy and duplicate keys

Price issue: MVP is a little expensive than ZED-Bull, but not very much. Both MVP and ZED-Bull price is in the range of $160 to $200.

Furthermore, Godiag T300+ and SBB are more or less the same with MVP, and AD900 is more or less the same with ZED-Bull. People who are interested with car key tool can get to know about them.
