Thread: nanocom key programming

It should have a piece of paper stuck to the circuit board with the number.

If that is what you mean , you can always just try it without the 0 and with it.

Surely if the key comes with the code it should be prominent.

Ah ha! took the circuit board out, got the number. followed this
The problem I had with one of my ignition keys losing its association to the vehicle BCU has been resolved. For those who may experience the same problem, perform the following CAREFULLY:

1. Open the ignition key fob and remove the circuit board and battery in one piece.
2. Write down the 6 characters printed on the chip on the underside of the circuit board.

If you have another working key, keep it handy with the non-working key

3. Start Nanocom and select the Valeo BCU tab
4. Select "Utility" from the left pane
5. Perform an RF test with the working key. A success message will be displayed stating the key number
6. Select “Key Inner Codes” from the left pane of Nanocom
7. Click “Update” to display the codes stored in the BCU
8, Enter the number from step 2 into any of the key fields, except the field which is the one for the working key identified in step 5
9. Click “Set Code” next to the field you just added the key number from the non-working key.
10. Click update and check the new number was written to the BCU
11. Perform the "Key Sync" function
12. Disconnect Nanocom and check that the key works.

Key did not work. Hmmm.

Did you do a Rf Test on the new key ?

Yes, I get "A key signal was detected" I sync the key and I get sync successful or similar

Hi, IMO 0 can't be the first code number and the code is not the number OF the chip it must be on a paper label on the chip, see attachment, if your's doesnt have that i'm sure you can find a shop somewhere close to you where they have dedicated key programming equipment cos those dont need any code, it works like the little green programming device which is used by remotekey.uk http://www.remotekey.co.uk/land-rove...-1999-to-2006/

I've had another go and got the number 4****7. I was looking at the number on a chip next to the battery, then took the board out and saw the digits printed on paper, glued to the chip.

Still not able to program the key.

Is the O a letter or a number? Did you try both?
It's been a while but I think I found a utube video showing the steps which need to be followed to the letter.

Im sure when I programmed keys with the Nanocom, I didnt need the code, the Nanocom just worked it out.
