I need a tool to precode PCF7946AT, PCF7947AT etc. chips

[allstar]

What tool i can use to precode PCF7946AT, PCF7947AT etc. chips.
And i will need the information i have to program to these chip ( the different info for the different cars, i know that every make have different info i have to put inside the chip and even car make have different info for the different models )
I think this info will benefit many user of this forum .

Thank You in advance.

ZedBull, TagKey, Tango...

The programming you need comes with the orignal Zedbull

ziggity ziggity zeddd bulllll

this tool can solve all problems in the world! :-)

will definitely work for what you read

[PierreTheron]

I probably i did not ask the right question, so i will change it.
I need a device that can precode these chips: PCF7946AT, pcf7947AT, pcf7942AT ( the chips that have the remote part inside a as well the transponder chip )
I am not interested in devices that can precode pcf7936 ( the chips without remote function inside)

I need to precode these chips and then program it with the official car diagnostic device or similar device
( i dont need a device for which i have to read the epromm of the ecu or the flash then to put the info from the chip in this dump and upload it back to the car ).

hi to precode the chips you need zedbull original

or something similar if no zedbull then you also need the central locking dumps to load on to the pcf chips

each car model has a different dump for the central locking

so there are many remotes these pcf chips fit...you need the file for each type of remote to program the central locking

clio...megane....Laguna....Kangoo & so on

Each has different file for precodeing locking

[allstar]

will the clone zed bull do the job and do this zed bull have these different file for precodeing remote locking for the different cars?

[coder5]

can fvdi precode these chips?

i bought some virgin pcf7946at chips ...... now i'm doing some tests.
I soldered a virgin pcf on a renault remote and now it sees it as id14.
how do i make it become an id46 so i can handwrite the pages with zedbull and program in the car ???
zedbull does not recognize me this id14 ....


thank you

[jodge]

try it with other PCB this looks like hardcore chinesium

edit:
solder only the 6-9 pins those are the coil legs

[joker01]

ok ... I try as you say to weld only 6 and 9 on the pcb of the second original key

[joker01]

the pcb of the original key is the same as the one in the photo above.
I tried the same to solder only pins 6 and 9 and read the tranponder but always the same reading.
i changed to a new pcf7946at but same result.
I then tried to generate image with sw zed-bull and effi 173 but in both sw it gives me "transponder error"
if I try to read on handy baby it reads me an "id14" on zed-bull "no transponder"
some help ........ my npx pcf7946at npx chips suck or my equipment can't do the job ???
thank you

Most lokely bad quality chips. To make sure use a used locked 7946 and put it on the same PCB and try to read. If the same thing happens with a used original 7946 then the issue is with the coil of the chinese PCB. If you can read it as ID46 normaly then the issue is with the "new" 7946 ICs.

[joker01]

done.....
putting pcf used on aftermarket pcb I read ok as id46 ....
putting pcf china on original pcb "transponder error"
I will try to buy new pcf ....
thank you

[joker01]

solved with other better quality pcf7946.....
thanks!!!!!

i replaced pcf7946 on 2 remote 1 botton renualt.
one is u original remote control and the pcf is unlocked (I can read and write all the pages) so I can reprogram it on another car.
The other is an aftermarket remote control (as soon as it arrived programmed on the car and 100% working) now I have replaced pcf7946 also on this but it is blocked.
I tried the procedure for unlocking but it does not make me modify any page ....... I ask for some info to understand what is wrong.
the pcf7946 come from the same supplier (same blister pack)
thanks as always in advance .....



I try to change with another pcf7946 ..... because as it seems to me it is already programmed and therefore blocked ....
