Use Yanhua acdp to add new key for cas3+ keyless go key, the key and remote can work, but keyless doesn’t work.
CAS3+ must be written on Key1 and Key2, and CAS must be rewritten before it has smart.
The method to match CAS3+ smart key:
1. Delete the smart key that was lost on the first 2 key positions.
2. Program new key on the same key positions.
3. A smart key needs to rewrite the data that is generated in step 2.
