How to determine whether a BMW G-series BDC key is encrypted based on the key itself or its appearance?

BDC2 keys are relatively easy to identify: if the key’s circuit board has a long encrypted chip, it is a BDC2 key. All BDC2 key are encrypted.

Many device will add key BDC2 by removing BDC2 module and make key on bench. CGDI K2 now will copy BDC2 key via reading data from the original key. No need to remove BDC2 module anymore. Keydiy and more tools will follow this solution.

 

How to determine whether a BDC3 key is encrypted?
Open the key shell and check the marking at this location on the casing. If there is ‘Hungary’ letter, it indicates an unencrypted key. If there is no marking or if it is marked “Mexico,” it indicates an encrypted key.

How to determine whether a BCP key is encrypted?
Open the key shell, and you will find a laser marking here. If it displays “CG,” it means the key is a low-spec, unencrypted version. If it displays “CA,” it means the key is a high-spec, encrypted version with UWB functionality.

CGDI K2 now will copy all versions BDC2 BDC3 BCP keys. Keydiy will also release this function.
