[giuliani77]

Hi.Need help to add new key for a golf 5 plus year 2008.
I write CS in a TP 23 and lock the transponder.Add with pin and vcds and result :Safe with the second key.
Error :implausibile signal.On the programmed key are 2.
Car start with the original key.
What Im doing wrong.
1 dont need to lock the transponder ?
2 must to stay with the new key in ignition some time after programming?
3 must disconect the battery after programming?


Thanks in advance.

Precoded chip must be locked before programming so everything is OK but maybe you have wrong CS written. What tool did you use to read and write CS?
