Hi

I have heard of some people being able to programming second hand key cards to new vehicles, I just wondered if anyone knew of hows its done.

Any Help would be good.

Replace chip, cards are very hard to take apart

You should always be able to match an used key card for Megane. For Laguna and other models you have to replace the chip.

With this software you don't need pin code

The ICC Immo Code Calculator (http://immo-code.com/#prices)can do the trick , but it`s very expensive ~ 500 euro for the basic package and the Renault stuff. After you get the pin i think a Clip or DDT will do the trick.

Am I correct in thinking then you replace pcf7946 in card, with something like this:

1 pcs IC Chip PCF7946AT PCF7946 Key Transponder Chip: eBay Motors (item 260614026401 end time Sep-01-10 11:48:20 PDT) (http://cgi.ebay.com/ebaymotors/1-pcs-IC-Chip-PCF7946AT-PCF7946-Key-Transponder-Chip-_W0QQcmdZViewItemQQhashZitem3cadce74a1QQitemZ26061 4026401QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccesso ries#ht_1881wt_939)


then you can reprogram into another car .:coffin:

or is there more to it ?


has anyone had success with this?

drivesure

yes you are correct obd master. replace 7946 and the chip must be in cipher mode and code into any of the renaults after that. done a few already.

Do i need a tool like tango or zed bull to put in cipher mode m8.


All i have at moment along those lines is gambit what tools can be used to put in cipher mode m8, or will chips come in cipher mode m8?

so you can use a card off a megane on a laguna 2 m8?

Bit of a thread bumper this, if i got a zed bull clone using transponder production id46 would this put pcf7946 chip in cipher mode, or could a zed bull clone put chips in cipher mode.

much thanks as always.

sorry misunderstood, i use oe zedbull and that will produce id46 Renault cipher ready for obd programming, cant comment on the clone zedbull but figure it won`t be too far away from the origional,
i`ve used it for secondhand clio II remotes but never successfully managed to get a key card apart without destroying it....

hi obd, if you put the chip on the card it is generally in cipher mode. i have only ever once found a card not in cipher. the zedbull original pre-coded this.

obdmaster
5th August, 2010, 03:51 PM
but would new chips come in cipher mode such as these:

10 pcs IC Chip PCF7946AT PCF7946 Key Transponder Chip: eBay Motors (item 250644475194 end time Sep-01-10 11:48:50 PDT) (http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=250644475194&viewitem=&sspagename=STRK:MEWNX:IT)


or would i need to precode them with ZED bULL .

drivesure
5th August, 2010, 09:42 PM
you can only read once soldered on a card. so best to buy a few and solder on a card and then read it. i think it will be in cipher mode.

Tried renault laguna 2 card comes apart nice, but renault megane is a bugger. lol

Here are some pics, ive changed pcf7947AT succesfully have no zed bull clone at mo so dont know if in cipher mode, but so far so good.

here are pics of internal of laguna 2 card.

could always cut a hole around the chip just enough to remove it quickly without damaging the rest of the plastic then either put the piece that was cut out back or just fill the hole with epoxy etc.

Might not look the best but would stop it falling to pieces easily.

MrSporty
23rd August, 2010, 07:24 PM
Are you 100% sure that a factory fresh PCF7947AT works.

I have a card that i have replaced the chip on. I know the chip is virgin as i can read and write it with my Hitag2 programmer. Its definately in cipher mode (first byte of config is 0E) and the transport key is 4F4E4D494B52.

I also have Renault Explorer 1.5 and although i can re-code cards that are already paired, the card i have with the virgin chip still won't pair up. Are you sure that either some of the config data or user data doesn't need to be changed to make them compatible ?

drivesure
23rd August, 2010, 08:35 PM
i use my hot air station with a very mild heat and heat up the plastic slightly and the cut with a scalpel. it is like cutting butter. be carefull not to put too much heat otherwise you damage the plastic. when done i just suplerglue back together. good result.

I havent tried to program on car yet, drivesure m8, have you any tips to help me and mr sporty m8, i see on zed bull transponder production renault laguna 2 is there but it says use blank pcf7946, not pcf7947at, that are in the cards.

Any help is appreciated.:smokin:

drivesure
23rd August, 2010, 10:25 PM
if your card have 7946 then replace with 7946 and if it have the 7947 replace with 7947 . i have had no problems with the cards i renew in this way. i have used successfully on renault megane, laguna and clio 2 remotes as well as on the clio3/modus 2 button remotes which i renewed. all coded in to the vehicle.

MrSporty

Hi,
The chip is pcf 7947 not 7946.

You have to prepare the chip for programing into the car which your zedbull will do.

Are you using genuine or clone?

Yes I prepare it before by genuine Zedbull. I try 2 cards, same result by zedbull.

Hi,
if you are using the correct chip pcf7947
make sure the battery is in the correct way up
Try pushing the unlock twice quickly

I have done loads of these with no problems, I have had it where the central locking didn't work before I made a key?

I have succesfully used and programmed a used key card by changing pcf7947 and using my m8,s original zed bull preparing card. Then i can programme into vehicle and locking works . If you dont precode vehicle will run , but no remote locking. Done this successfully on laguna 2. Only done it once as the price of used cards is far too high, for the amount of time opening the card without damaging it and soldering and precoding, i now use new.

With this model of Laguna 2 or Megane 2 we dont prepare the card, we use Zedbull just to find the code pin and program it with another device like T300........ or if u have a genuine Zedbull u can use the Obd lead.

Hi new keycards are prepared.
Repared keycards need the pcf7947 formating to then make them the same condition as a new one.The formating on the megane 2 is different to the Laguna

new card for Laguna 2 and Megane 2 are virgins. so u have just to change the pcf7947 in used keycard by another one Virgin and Have the code pin from Uch, u will b able to program the keycard to start the car.

8th December, 2010, 12:13 PM
HI,
I think you miss understand. Its probably a language thing.
A new pcf7947 has to be formated, depeds on the type of keycard its being fitted in, in order to be programed to the car.
oddmaster reffers to it as "precoding" same thing.
A new unformated chip will not work the central locking.
I do loads.

Hi mate . Must precode with Zedbull . Then remote will work .

seems like you wasted a good pcf7947 at there.


Will have to use another chip and precode..

step by step instructions for you:

1. Buy a used card
2. Remove the chip
3. Fit a new chip to card
4. PRECODE the chip (if you dont PRECODE it the remote part wont work)
5. Extract pin code from car
6. Take your newly PRECODED card to the car
7. Program the transponder chip to the car with Zed Bull or whatever tool
8. Write invoice for customer and get your well earned money

Its as simple as that but you dont seem to understand the difference between PRECODING and PROGRAMMING the transponder. Basically it works like this, before the chip can be successfully PROGRAMMED it needs to be specially PREPARED first, when you prepare the chip this is called PRECODING the chip. PRECODING is a very important procedure that needs to be done before programming the transponder chip, so PRECODING the transponder and PROGRAMMING the transponder are 2 completely different procedures. When you buy a new card from the dealer it already comes PRECODED from the dealer so therefore the PRECODING step is not needed for new cardsm ONLY used cards, hope this explains it better for you

Thank you for your brief tutorial. Very useful.

Since I am kind of new in the key programming theme, I would like to ask a couple of questions.

a) For the precoding of the card, how or where do I get the precode for the card?
b) To extract the pin code from car, what tool or software I must use. I really don?t know.
c) Does chineese clon zed bull can do this kind of procedures?

Thanks for your prompt reply and help.

my company can do it. someone send me sample, i can help. PCF7946 is not so hard.
the chip will still need to be precoded, but at least you don't have to remove / reinstall.

well, i say that it must be precoded.....the precode is same for all these cars? or each one is different?
if it is same for all the cars, we can precode it, too

Hi,
once you program the key to the car ( say clio using pcf7946 since you say that one is easy ) The pcf7946 goes into cypher mode and can not be re-writen. In thoery it can if you know the lock code. but thats the big secret.

So how are you going to re-use a programed key?

same way i do the chrysler PCF7941, mitsubishi PCF7941, bmw pcf7945, bmw pcf7953

saab, land rover, jaguar smart keys

gm flip keys

the list goes on and on....almost every locked key in USA we can unlock now.

if there is demand for it, we can certainly try it. i have sample for renault smart card on way to me, i can post updates in here. normal it takes 2 or 3 days to crack a key, so maybe in one to two weeks i have some news.

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

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?

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...)

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


I can do a bit more with this chip id 46 for renault .

I can write vin number
I can write customer info or change
I can write service information to it .

I can see km reading on it

i can see tyre pressures if fitted ..

I can see oil level

I can see fuel level .

So this chip can have a lot off info on it ..

Do you want me to send the reader to you ???.

Actually have no use for it exept to write my info onto card when i repaired .




But off course that is with a different reader that only allows me to do only this..:help:

The PCF7947 could be re-used if we had the lock code, but its a secret only used once to lock the chip, each car being different.

So when we program a "new" card to the car the equipment must send the lock code.

My point is that we must know the lock code at that point, so the equipment makers could tell us the lock code it has just used.

If that happened then we could at least re-use the pcf7947 if we made a mistake, say forgot to pre prog the vigin chip.

We may even be able to re-use the keycards if we new which car they were locked to using the aformentioned lock code, thats hoping the code is unique to the car and not to the chip.

I have re-used many second hand cards. First cut card apart with a sharp stanley knife. (mind your fingers) then remember which way up the pcf7946 eeprom goes. de-solder old pcf7946 and re-solder new. All new pcf7946 are in password manchester mode. Only re-prog car on a zed bull if you want the card to be in cipher mode.

I am not talking about re-chipping the card. New chips are in cipher and then go to Locked when adapted to a car.

I am talking about hacking the security on a used card.

Hi,
once you program the key to the car ( say clio using pcf7946 since you say that one is easy ) The pcf7946 goes into cypher mode and can not be re-writen. In thoery it can if you know the lock code. but thats the big secret.

So how are you going to re-use a programed key?
Hi

if we have the reader capability's to unlock this chip??

Who knows .. then we might get closer to decypher some more different chips

and then we need a DECODER FILE TO GET SECRET CODE ..

Hi ,
I have 2 used megane 3 button cards. And also bought one new card from Renault. At least the person who I bought told me it was new and never programmed.
I try to read with ZedBull all the 3 card. The 2 used cards I can?t read them. It always say "No transponder" or "Could not read chip" depending or card position. Is this normal ?
I can read the new card. ZedBull says:
ID: C9CA1154
Mode: LOCKED
Type: 46 CRYPT Philips

Mode Locked means that this card has already been programmed ?

Thanks

Hi,
Today I received some Megane 2, 3 button key cards from China. They are new, to be programmed.

Are you sure that "Locked" means that no programming is possible ?

If you cannot read the cards (all green lights = unlocked) you get all red lights = locked

open the used card You buy cheep
chage the PCF7947 Chip ( i testet it with this One ; other One are also Supportet) in ebay you Can buy a Lot of for 15 Eur
if you buy a precodet it is easier But not more stromg
if you change the Chip PCF7946 you take the TAG keytool . In the top on legt you can Choice precode / Pepair
than you take your Modell , look for the right IC and Start.! Importanz you must do this After change the Chip and before you learn it to the Car.
