This is ok, but read-ed as pcf7936, for proper remote must select pcf7946 and from picture user page 2 & 3 rewrite on RCF & sync page on 7946.

Question and Answer on Vectra C 3 Button PCF7946 precode
Q: After writing remote data is no more visible.Is that normal?
A: it isnt normal … must see sync & rcf page, only if you set cfg byte on page3 different

Q: Just found out, if is because TMCF byte is 0E and not 06.If it is 06 then pages are visible.
Can anyone confirm coolsoda precode works?
A: thats byte about i talking, first in page3, in pcf 7936 that 06 password mode, if 0e thats crypto mode, but on pcf 7946/7 you can see what exactly switch … work for sure if rcf & sync are as last 2 pages on coolsoda picture, tried many times …

Finally, confirming Coolsoda precode works. Coolsoda precode works with TMCF byte set as 0E, direct as Coolsoda
