[Kprog]

Hello, I wanted opinions of which is more complete and better, since CGDI has been on the market for a long time, I suppose there will be a clear opinion.
Regardless of price.
Which one does more?

What differences between them?

If someone has both and can comment, I appreciate it, I don't know which one to buy !!

Make some new key.
Adapt used EZS when the car's EZS is broken.

I have a question, a friend has VVDI MB and the same thing always happens to him.
Is there any way to fix it?
or is this always the case with VVDI?

VVDI, we have desoldered the NEC from the key to obtain the pass. then solder the NEC back and the key no longer syncs with the EZS.
VVDI says. "if the key does not synchronize, insert and remove the key several times in the EZS"
But even doing that doesn't work.
For it to work I have to unsolder the NEC again to erase it and make it new

Some people say you just need to leave it in for more time. But me - I think it saves time and makes it easier to just renew the key each time after the pass is extracted.
