As I understand it they are just sequence numbers. You can get keys 1,2,3,4,5,6 etc.
They are made by HuffCell and they are a series of keys that your BeCM can understand from the Base pair (1 &2). So, if you lose key 1 from the first pair, you can get key 3, then 4, etc.
There is a relationship between the keys you must buy from the main stealer/HuffCell and the base number programmed into your BeCM.
Buying from flea-bay probably does not work.

Sticker has rubbed off on mine. All I can remember is #1 on it when I first got the car.

1-4, no key 5 or 6 as far as I'm aware. 1 and 2 come with the car. 3 and 4 are replacements.

ta!... I had hoped it was a limitless supply so I can be really careless rather than car-less.

There is no *easy* way of telling what key # you have (unless you come visit me in Swindon, or send a fob) if the sticker has rubbed off the back of the fob.
There is one way of finding out if you have a key #1 or #2 on vehicles with memory seats. If you superlock the vehicle and then lazy unlock the vehicle (press and hold the unlock button) then the memory seat will move to either memory position #1 or #2 depending on what fob unlocked the vehicle. Key #3 or #4 won't have any affect on the memory seat. That does rely on you being willing to superlock the vehicle and hope that all the doors actually unlock again and don't stick in superlocked mode!
I have a fob checker that was made for me which decodes the fob transmission and will give me the hardware code the fob transmits - from that I can work out if it's a Key #1/2/3/4.
There are only 4 possible keys that work for a vehicle - ones from eBay won't work without capturing their code and programming that lockset to the BECM - but you will lose functionality of any existing remotes. The BECM is programmed with the ID of a Key #1 and then it will accept transmissions from that key and the next 3 keys. (to give a total of 4 in a lockset). So as a random key from the likes of eBay isn't from the sequence of ID's that the BECM will accept, it won't work - unless the starting ID is programmed to the range that the replacement key is in. The chips in the keys that the hardware ID is programmed into is One Time Programmable only - so even if it were possible to find where in the chip memory the ID is programmed, it isn't possible to change it - (which would then make it possible - to reprogram a key into the range the BECM would accept)
If anyone is passing Swindon way (and I'm actually home and not away working) and doesn't know what key # they have, then feel free to get in touch and I'm happy to try to read the transmission on my tester and work out what number key you have.
