We already tried on more than 30 cars, it works great, easy to use and its update itself every year. So no need Subscription no extra pay.

I purchased the Autel MaxiIM508 to add keys to my BMWs. I added two new keys to my 2009 without having much of an issue and now I have three working keys. I also reprogrammed a keyless entry remote for my 2005 F-150. So far, so good…seems like a legit key programmer. I used just the IM508 with the included XP200 for the key programming I mentioned, I did not need any of the additional add-ons that are available. You may need the add-ons for other makes/models, I don't know...The IM508 also has diagnostic features and live data, so that is a plus for the tool
