tango.....

[sharingkey]

regard the tango ,you read the virgin data from one new laguna card,and copy the data to the new 7947 chip!
after that you can using the renault key programer or other tools to program it ! if your data not correct,then your key cann;t open the door only can start the car!

[NiZaTroniC]

yes thats right for the pcf7947 used in scenic and megan un need to write this value A1 01 0F 07 to get a full working card

pour les pcf7947
La page 6 ( RCF ) correspond ? la centralisation.
Il faut la valeur A1 01 0F 07 pour qu'elle fonctionne

Sur certain lot chinois, cette ligne est vierge, et la condamnation ne fonctionne pas
cheers

some chinese sites are saying that you can use pcf7936 for megane card system (put carbon chip in blank case - only for starting), anyone tried this? or need any pre coding first?

This seller has sold only one device. And it is unclear what kind of quality. I've had one such device mint, high risk.

There is some specific data to pre code a 7936 then you can program by obd, I just need that data!

I will try to copy pages from a 7947 and give it a try

Let us know if it worked for you please

[kleidaras]

If i remember right you need a transponder on Crypto mode. Change on page 3 the 2 first digit. Now is 06. You need to make it 0E.
try it!!

Hi all,
For a scenic 2 (PCF7947) (3 button card) can someone give the codes to precode (I can use the codes from post 9?) but I need also the REMOTE part.

I can confirm, for a scenic 2/megane 2, 3 button key card, you have to write at line 6 (USER 2) the code A1 01 0F 07 (given by COOLSODA and TERMINATOR1000) and than when I read again the PCF I found at line 6 (RCF) from REMOTE part the code A1 01 0F 07 (Maybe I could write it directly to the RCF line from the remote part but I didn't tried).
See original china PCF 7947 and the same PCF after precoding

I used a ZED BULL MINI clone to precode the PCF and than a CLIP Clone to write it to the car and now everything works remote and engine start.
Thank you all for your help
