I paid for a license of obd jscan for my vehicle since it is specific to Dodge/Jeep it can do everything, including activation of features and access to all data in the vehicle. I had to buy a more expensive vlink adapter, but it was only $20 or so. It has saved me tons of money so far. I was able to program keys, activate remote start (had to install a hood switch), and have been able to diagnose several issues with things like tpms and abs.
