If you drop me a PM or post the 6 digits off the sticker I can generate the barcodes

If the barcode tag was NOT attached to the key, how would I know to substitute the normal "N" for this "P". Is there any code reader that can identify the I/Cs programming / coding - so as to identify if a different letter has been incorporated in the coding.

Or if one has a key without the barcode tag, do you just use a trial and error approach, selecting different letters in turn. Does anyone know how many alphabet letters MG Rover / Valeo used?
I had the mistaken belief that, in the barcoding industry, "N" indicated the small sized barcodes. How wrong was I.

Maybe this could be the reason that some garages here in my home city have not been able to code some of the remote keys. And this may be the reason that my friend believed his T4 had failed.

Bruce.

FYI.....

Some codes that Valeo used for identifying fobs (first letter of the barcode)

N = MGRover
G = LandRover
U = BMW Mini
J = LandRover USA
X = BMW Mini USA
M = LandRover SLS
I = LandRover 315 MHz
P = MGRover 315 MHz
D = Rover 600
C = Rover 800

Barcodes all based on the standard Code 39 with modulo 43 check digit.

My friend has the use of the dealers T4 and asked to come around as his T4 wasn't working. After trying to install the remote code with my unit, I now understand why he thought his T4 had packed it in.
I may discuss this further as there are a few anomalies with this remote tag.

Meanwhile, here are my figures.

Code on the remote circuit board: 3 D 7 6 4 3

Top string:
Barcode listing: P 3 D 7 6 4 3 3 D 7 6 4 2 F F /
My calculation: N 3 D 7 6 4 4 3 D 7 6 4 3 F F /
Second string:
Barcode listing: F F F F F F F F C 2 8 9 B C 2
My calculation: F F F F F F F F C 2 8 9 B B 1

7th. and 11th. items in top string differ. 14th. & 15th. items in second string differ.

Regards,
Bruce.

The correct codes for 3D7643 should be

N3D76433D7642FF_ (last character is a space)
FFFFFFFFC289BC2

The second string will never change regardless of the first character on string 1
