I had a problem that I could not reformat/renew the Mercedes keys with Autel im508 xp400. Are there other ways besides this one?
Aute can’t clear/renew original Mercedes key. OEM keys do not work. Only BE keys.
The type of this key can’t renew of this way, but you can use other way desolder nec chip put it on adapter read data chip and renew.
You must be able to reset Chinese v51 keys. Original keys can only be reset or programmed thru nec programer, i.e AK500.
That mean you must desolder nec chip from inside the key, put it in programmer that can program nec chip, and program key file. Can not be done thru ir by any programmer.
You can also use ak500 to rest the nec ic and write back file with vvdi mb.
