You have to changue pcf7946(desorldel the used one and Solder a new unlocked) and after precode with the right tool, conclusion is better buy new ones :top:

no you cannot use it on another car for the remote but can program to start the vehicle.

you need to do as said before change chip and precode

just tried to program this on micra 2008 with avdi , but didn't find how to read 12 charters code , any help?

[keysph]

Glovebox label or bcm dump

[totalkey]

Micra K12 It's like the Renault clio 3. For this I use true Code. Retrieve the pin code automatic

This thread is about Nissan remote, NOT pincode...

Incorrect....

change chip precode with central locking with Zedbull or Hitag 2 or any other Hitag software
program to car
it will start & work the central locking once programmed
i have changed loads of the chip & don't have any problems

Not matter what car it came from
once chip is changed & loaded with the software for the central locking its new....
there are 2 types
1..with PCF 7946 chip soldered to the board
2..one with ID46 chip in the corner of the case

[obdsystems]

and with the ID46 (pcf7936) separate chip switch the ignition on 6 times and press lock button down while unlock 3 times (or vice-versa i cant recall :) )

you really did not read my answer .

in the present state the use remote cannot work in another car , unless you replace an item as said before , by viejomatius (http://www.digital-kaos.co.uk/forums/members/58418-viejomatius/)

[P&D]

Sorry not sure i don't have the program
does it have hitag built in the program if so yes

you just need the file for the central locking
do you have a zedbull if original it's built in to it

i have uploaded the file below

file 1....zedbull file
file 2..hitag2 file

these are the file you need to load to the chip before programming it to the car
so solder the chip to the board then load the file with the programmer

can you show a pic on the remote pages what bytes to write ?
a picture will be nice .

thanks cj

thanks brother , that was really nice of you , i am sure this will help a lot of people in the uk , my side of the world not see too much of these type remote .

but you never know when one will come .

[whiskeyman]

hi was trying this today
am i having a blonde moment
i load file same as in picture
i press write tm
but stops on first page as it only read?
the write button is not highlighted?
hitag reader wont write

does it need to be soldered first?

[kemaster]

Not sure if I understand you correct but are you saying you try to write page 0 IDE ? This is read only. And how you could write 7946 if it's not soldered. :)

[whiskeyman]

As never done before this why I ask mate

[drakov]

My question is why bother?

[P&D]

My question is why bother?


2nd hand remote ?2.50 - ?5
new case & blade ?2.50
new PCF7946 $3.50

Total cost of a new remote ?7.25 - 10

[P&D]

As never done before this why I ask mate
Yes needs to be soldered to the board 1st

And your hourly rate is? or do you charge per minute?

[whiskeyman]

i solder new pcf7946at chip to board
i load tm file in hitag
i press write
nothing?
where i go wrong?
wonder if got bloody dodgy chips

does it have to be some different pcf7946at?

and yes my soldering is very good

[whiskeyman]

either watch soaps with the wife
or tinker about with remotes.................................no brainer:chuncky:

[P&D]

And your hourly rate is? or do you charge per minute?

To renew 10 of the remote's cost's m 1 hour of my time
i'm not arguing with you...just answering your post WHY.......would you make a remote for a tenner.....or buy them @?40 +VAT each ??

10-remotes cost me call it ?15 each Max (?150) or buy from the NW or 3D in the for ?400+VAT

Again not pissing on your bonfire just answering your post.........

1st read chip
then load TM
then write then read make sure data there

could be dud chips where do you get them from ?? (if you want me to send you some for free just to check PM me i will pop them in the post & give you a link where to buy good ones)
does it have to be some different pcf7946at? (same chips i use bought & used maybe 3000+ yet to have a dud)

silly question but have to ask ;) lol are you sure the chip is the right way round lol

When you solder new 7946 to PCB and try to read it do you read it with success? Does it show you factory settings?

[whiskeyman]

was talking to cj today on skype
think ave dodgy chips
nothing seems to read the blank chip
and yes solder is ok on both the boards i solder onto
we even heat legs and pads again to double check
we try everything

[mikajna]

Friends, does somebody have precoding for PCF7936 Nissan Micra, effi just have for pcf7946 but I need just transponder only...can I write bytes for PCF7946 on PCF7936? Are they same?

Thanks in advance

There is some dodgy fake chips out there, I built a test rig out of an old remote key and a test socket.

I found the chips which are printed NXP tend to be the dodgy chips I had some pcf7947 that were all dead (I believe they have just got some worthless IC and reprinted them), and from another seller they were labelled pcf7947 but are actually pcf7946.

[lion0304]

I have 10x 7946 and 7947 blank. All are fake. Sold on pcb but cannot detect the chip

just program the 7936 in via the OBD no need to pre-code..........just needs programming.......

All my chips have the NXP on the chip........used them for the past 4 years without a problem
so i guess it's where you buy them from......is the problem Paul.......unless i'm just lucky ;)......Never have been before lol......good job i have bad luck otherwise i wouldn't have any .....lol

Would you like to share where you got them from so other members don't buy them ?

I'm not saying all the NXP chips are fake, just that it seems who ever is faking them seems to be using the new logo.

So for now at least if you can find the philips ones its more safer than the NXP printed ones, although I'm sure the fakers will start printing the philips logo if people start asking for the philips ones.

of course if you buy from a decent seller in the key trade they will probably be ok.

[P&D]

Not saying you was Paul sorry if it came across that way.......I totally agree with you & it....sum's China up down to a tee.

Anyone want good chips 3.5usd http://www.supercarkey.com/05-chanpin/p-001-1.asp?id=1211
been using these for a while NXP chip but never had a problem with them

Thx phil

I purchased on Ali an year ago from electronic sellers components. That is my fault.
Just buy 10x from here: http://www.aliexpress.com/item/Free-shipping-10pcs-lot-Original-Brand-New-For-Renault-Pcf7947-Transponder-Chip-For-renualt-car-key/32253095507.html
I'll test them when i received.

[mikajna]

Thanks @P&D on answer its really good tip to know, is there any other car than Nissan, which accept blank pcf7936 without precoding? I never heard that for ID46, for Megamos and 4D ok, but I was think that all ID46 must be precoded before programming, without exception.

Hallo

Just a quick question to this interesting thread.
If i understand well, Nissan remote are reuasble if you have the patience to replace the pcf7946 on the board.
By the way after replacing you need to precode the chip, remote part must precoded with the example provided by P&D Member.Right?
The Hitag remote page could be programmed manually inserting the value on pages, or loading the file provieded by this user.
Can i use Tango to precode or load the file provided?
I've heard that pcf7947 are usable instead of pcf7946.
Is this true?Can I use pcf7947 instead of pcf7946?
Thank you very much for the grat info.

In Reneult remote key can use 7946 or 7947 without problem.
I did several by myself. Just input the correct bits with RF section.
For Nissan, not yet.

I'm tring to reuse some nissan remotes.Before made some mistakes is better to ask expert.
The user P&D post some file about hitag2 remote config.
The first file about Micra is readable with hitag2 software but the Nissan navarra file for zedbull have strange value, so i think it's incorrect format for my zedbull software.
I need precoding for navarra remote.
What value i have to write in hitag2 pages? Only remote pages or also sk high in transponder memory page ?
With hex editor i think i have find the remote page configuration.
For Navara are:
SK Low 4D494B52
SK High 00004F4E
Config: 00640205
Synch: E9B8FD23

Are these values correct? if not what value i've to write to remote page?

For Micra (as displayed in hitag2 software)

SK Low 4D494B52
SK High 00004F4E
Config: 00640205
Synch: E0C92BDF

The Sk high in transponder memory must be changed or i can leave the original one?
The config file in transponder memory is 06AA4854 and it's the same on every reading only sk high in transponder memory is different.
Can i leave the original from virgin pcf or i have to write the value displayed in the file.For Navarra seems : 3ACC4F4E and for Micra is AA1C4F4E

355129355130355131
The last image is taken from tagkeytool and it's a reading from a virgin pcf7946.
Any info are welcome.
Thanks

Just to revamp this thread.
Last week i've tried to do a key forn Navarra.
Readed BCM code with SBB and converted in working pin.
I've a remote key with changed pcf7936.
First i've manually program the hi-tag pages and remote pages with AVdi, than i've tried to
precode the key with AVDI function (Precode Micra Remote key).
In all cases the remote part are the same.
Than with SBB using Nissan NAts coding function, i've learned the key.
The key now start but remote not working.
Is there a function to do remote sync or something goes wrong during coding key (or in precoding data).
Which is the best toll to do remote coding?
After coding i've re-read the key and the pcf7936 is not locked so if i want i can change the values.
In the next weeks customer return to do another job so i can retry the procedure.

Thank you

[P&D]

If the chip is a 7936 programming the remote for the doors is manual....


1. Turn the ignition switch from Position 0 to ON 6 times within 10 seconds.
2. Then turn ignition switch to OFF position. Take key out of the ignition.
3. After 2 seconds, the system will enter programming mode and will flash the warning lights twice.
4. Press and HOLD the unlock button on the Plip.
5. While pressing the unlock button, press the lock button 3 times.
6. Release the unlock button.
7. The warning lights will flash once to indicate successful programming.
8. Repeat procedure 4 to 7 for up to 4 plip key’s.
9. When completed turn ignition ON, and the warning lights will flash 2 times.
10. Remove key, and check all plip key’s for operation.


Not sure about the Navarra tho
Also once you program a 7936 carbon chip it should lock

[armpower]

Hallo

Juts to add some info.
I've precoded the key with AVDI function.
I have coded the key with the help of Nissan function of AVDI software.
The key have inside a pcf7946 so during key learning the remote was also programmed.
Key and remote work without problems
Thank you guys
