Where to get CGDI Mercedes Benz key programmer tokens for free?

Just buy this CGDI Mercedes Benz key programmer and how to have free token , were to buy token ?

Solution: 
Step 1. You need to activate your CGDI MB tool first by your seller.
CGDI MB Activate Steps:
1. Download Benz Monster software from official website http://www.cgprogcar.com/ , there will be user manual too in the software catalogue
2. Install software on your laptop and read out serial number of your CGDI
3. Send the serial number to the seller, when activation is done, please restart CGDI Prog Benz and the Benz Monster software, it will be ready to use.

2. After the tool is activated, it needs to connect to server by internet, and you'll see at the right task bar.

3. CGDI MB Tool can calculate the password twice free each day for the first half year (from the day you activate device). Each day 2 PSW query + 10 generate key dump for free.

It will cost 70USD for another half year tokens, and after you pay for it, you can calculate online two times per day too. (to get new authorization for tokens, it will take about 12hours after you pay 70USD to us)

What's more, if you have CG100 PROG III Airbag Restore Devices or CGDI Prog BMW MSV80, you can pass us serial number to bundle them together and you can have more tokens too.
