I used CGDI BMW to program key to 2016 BMW 5-series, it's perfect!

For making keys it has worked great. I have made about 7 keys so far all CAS types except CAS4.

I have BMW Explorer and have used Autohex as well, but if you only need to program keys and your not concerned with ISN for DME swaps, I would buy the CGDI before those tools.

For the money its worth it just to be able to program the CAS3 keys. It works super fast literally less than 2 minutes beginning to end. Faster than BMW Explorer for sure. I have yet to successfully do FEM key with Explorer so as far as Im concerned it has the same key programming capability as the CGDI.

Programmed BMW E65 all keys lost within 2 minutes. Very impressed.

well i finally got the job done and all went well.2005 bmw e64 645ci,all keys lost,i ordered 2 new blank keys and unlocked them and then programmed them and then locked them,then cut the key,diamond style,remote,now just need to make second key,and delete non existing keys,and leave the system ready to accept new keys and remotes,another great tool good job guys thank you!

I bought the CGDI Bmw so I could install a used mechatronic / EGS module in my 2014 X3 F25. This tool was needed to clear the ISN code. Without this the car would not shift out of park. This worked flawlessly and only took a few minutes to complete
