Yanhua ACDP supports CAS3 key programming via OBD. In this post, I will share a guide about using Yanhua ACDP to add key for BMW 08 3 series CAS3 via OBD.
Note: the ACDP software itself only support read and write CPU, if you want to do CAS3/CAS3+ key program, you could pay for the module:
First comes the video:
Car model: 08 BMW 3 series CAS3
OBD plug position:
insert the ACDP into the OBD plug
insert the car key
Turn to the Yanhua ACDP APP, and choose “BMW”->”CAS3 CAS3+”->”OBD mode”
There are 4 steps
Step1: Read CAS data
extract the key and wait for 5s then tap yes to continue
read IMMO data successful
save the data “CAS3_ORGKEYxxxx.bin”
check the BAV adapter connection and prepare a blank key
choose the IMMO data saved in step1
choose the key NO.
choose the way to program key, choose “add key with key”-> “not smart key”
insert the blank key
save the data “…DLRKEY…bin” that would be used in step3
Step3: update CAS data
insert the original car key before update CAS data
choose the key data “…DLRKEY…bin” increased in step2
choose the way to program key: add key with key
updating CAS data
updated data successfully
extract the original key and then insert the new added key
successfully turn on switch and start engine!
if the Steering Lock is fault then need to do the ELV synchronization
choose “special functions”-> “synchronize ELV with CAS”
synchronize ELV with CAS successfully
insert the new key again and turn on switch, start engine and see dashboard shows normal and no fault code!
