Does anyone have any ideas what the issue is? Should I put the new skeem in as well?
The old key is the only one I have and it's in bad shape.
Thanks for the help.
The antenna ring isn't needed if the old one is not defectiv.
I don't know if the new Skreem from Needwings is a Clone of the old Skrem. In the Skreem are 8 keys programmed (the codes for the Transponder) key 1 and 2 is always used by the original keys.
I suppose, because nobody has managed to clone a transponder yet, that the transponders themselves still have a kind of serial number. And this number will be married with the Skreem when you use it for the first time.
That means if you have two transponders which have the correct code to unlock the immobiliser, they are unique because of the serial number and the transponder which is first used with the Skreem works, the other does not.
Would mean for you if the new key of Needwings is one with the code of key 1 or 2 and the workshop as suspected by onehundred80 has not installed the new Skreem module or has installed the new one and first used one of your old keys the new one can not work.
This is only a guess until now, because I can't create a transponder to verify this because I don't have the right hardware.
