 Hi,

If you need to do real key programing then you need some tools I already using them
Vpc 100 to get pass codes
Spk 900 for porsche and all most all other cars
Ak 90 key programmer for bmw
Ak500 for benz

Hope this will help you

I spend a lot time to know good key programing tools

   

  for benz and bmw  the digimaster3 works great. this tool is mainly for odometer correction but it is known to be the best for key programming on benz and bmw. also abrites commander but it has to be original, do not attempt key programming on this vehicles with the clone fadvi. you will be very sorry you did. for the rest of the vehicles there are many tools ck-100,ck_200,skp-900,tcode pro. etc.

http://www.wobd2.com/wholesale/auto-key-programmers/    all tools here are best quality tools  but above all they work 100% guaranty or your money back with a 12 month warranty. I know this site for more than 3 years and have tested many of their tools for quality control and functionalities. I make no profits  whats so ever just friends with them. before buying any tools register at the site and ask all the questions you want. make sure apple is logged in to chat with, usually after 9 pm eastern time which is 9 am in china the next day from sunday thru Friday. prices reflected on the site are not the real prices sometimes for example the maxisys pro its for 3900 dollars but if you chat with apple and tell her I jose sent you she will give it to any member here for 2300 dollars free shipping to usa, and every other tool with an 8% discount. Enjoy.

Which tools do you personally use? I do mobile diagnostics and programming and
have issues with keys all the time. Do you have a locksmith LSID?

 I have many key programming tools probably most of them but I mainly use the ck200
and the skp900 for what I do. Neither one does bmw and benz, for those I will say the
digimaster3 is probably the best one.

keep in mind guys just because they sell this tools it does not mean they are legal to use. china even sell machines to cut keys and code them. in many states is a 10,000 dollar fine if you get cough doing this. check you local laws  and get license or hide and make sure you don't get cough doing this. its the law and it applies  to many other country as well.  so stay away from cutting keys in public among other things  if don't have a locksmith license.

Which vehicles do you mostly work on?

Mostly Asian for key issues.

The ck-100 is the most affordable one but if you can afford the 200 model even better
also skp-900.
