Renault Used Key Card Programming?

**indienick** · 5th September, 2012, 03:35 PM

can someone tell me some information about this key?

i don't know Renault very well.

how many different smart cards are there?

do they work in more than one country?

i.e. just using random countries as an example....if the renault smart card in France is not compatible with the renault smart card in Spain, etc, we need to crack both, not just one.

if each country uses a different smart card, i need to crack them all, if we want the remote to work.

any good info out there regarding this key and it's compatibility?

and what is the professional reference for it - "key card", or "smart card".

thank you

Hi,
as far as I am aware the difference from country to country is frequency not the contents of the chip.
Pages 6 and 7 differ as far as virgin dump goes from car model to model.
So for example a Megane 2 has a different virgin dump to a Laguna. But as long as we can re-write the chip, 7946 and 7947 thats no problem.
Megane scenic clio are all interchangable as virgin cards. Laguna espace and Velsatis are all interchangable

when i worked with the BMW....the software appears same for 315mhz and 868mhz...but they don't work together. i have to make two separate procedure to unlock them. i hope it is not same for renault KEY CARD hehe

I dismantled two Megane MKII cards, one 315MHz and the other 432MHz. The only difference between them was the oscillator and the ceramic caps near it.

Megane II/ Scenic II- 2 types:
Normal with PCF7947
Hands free PCF7943AT/422
Laguna II/ Espace IV/ Vel Satis- 3 types:
Normal 2 buttons PCF7947
Autolock 3 buttons PCF7947
Hands Free 3 buttons (no hole) PCF7936+ rf board.

PCF7946 can be used instead 47

Megane Hands free does not use PCF7947
it uses PCF7943AT/422

What tool can prepare card to program to new car without opening card? And is it possible to program used card with carprog, or card must prepared new and precoded first?

Most important part inside of card (normal) is transponder- usually PCF7947 that can be programmed just once. So you CAN NOT PROGRAM IT MORE THAN ONCE OR/AND MAKE IT WORKS WITH OTHER CAR THAN IT WAS PROGRAMMED!! If you open "used" card, replace transponder, solder it to the board, precode it (or buy precoded), then card become "new" and can be programmed with car.

"Used" card with fresh chip become "new".

Is that clear?

Clear. What tool can precode new chip? Zed-bull clone can? Or other tool?

Zed clone can if you know how to ..

(You will need a bit off reading here on dk and some needed transponder (Precode files)

The problem is that with whatever reader we have we can not see alll info that can be in the chip ..

How can i explain it???

The manufacturer off a certain key programmer actually wants to sell us something to only do what they want us to do ..

So they must have developed some reader that can see more than us ( Some backdoor software ) . So they give some software part we can only see on the chip and manipulate .

All i know is that once chip locked to car some info gets hidden .

(there must be a backdoor or software that must allow you to see what happened to that data...)
