Hiow important is the RED key
 

And why have the RED key. whats its function.???

Its got the chip for registering other keys to the ignition/immobiliser. You'll never need it if you don't lose the black keys.

I was told by dealer that if you lose red key & you then either lose both black keys or need another black key, you are f**ed!!! Basically, a complete rewire/new wiring loom is required. Something about the immobiliser being paired with the red key. I think it would cost lots of ����/$$$$$ to sort out & would have a not insignificant effect on resale value..... Anyway, how hard can it be to put the red key along with your passport, birth certificate, other valuables etc. into a cheap home safe.

As said above if you loose the red key, and the 2 black ones, you'll need a new ECU, new igintion barrell, new seat lock and the whole thing will cost A LOT of money.

Also if you try to flog a bike without the red/black keys only a breaker's yard will buy it off you for spares and give you little for it. No one will want to buy as it will look well dodgy.

cheers Guys... so ye`s are sayin, as long as the two black keys are safe. its all hunky dora...as number 13 came along today at a good price...13 unlucky fur some..no red key,, the guy bought it fae a dealer, an never got a red key.. al need tae put the spare black key in ma safe....cheers

Ish....
 

Well your bike is worth less as u dont have a red key and you cannot get a second key cut from the black one, so u godda be VERY careful not to lose the first black key. Ask the previous owner and or the dealer if you can BUY the red key if they can find it........

I'm in the same situation, i put my red key somewhere so safe, i can no longer find it. A real pain in the arse, i've looked everywhere, and to make matters worse, i had a massive clear out just before realising it had gone, so its probably in a landfill somewhere.

Gulp!!!
I also read somewhere that you can accidentally 'erase' the black key magnetically or intereference from other electrical sources. You then take 'erased' key along with original red key to dealer, who will reprogramme black key using red key data. So: DON'T LOSE RED KEY AT ALL COSTS!!!

You also can make a copy of the black key without the red one. I thoght it was impossible but not.

Red paint for sale:hb:

maybe YOU have the red key hidden away.????:sad4:

I cannot remember if it came with one. I seem to think when I traded it in for the Tenere It was the first time I had seem a red key.

I was told it will cost over �600 to replace the immobiliser etc if you lose the red key and need to re-program a black key.

I would have thought a bike is worth a fair bit less without a red key.

If you are stuck & have lost your red key & unable to start your bike because of lost keys, contact me via PM for help.

I will not give the info on how to start a XT660 without the keys in the open forum & I won't give it to anyone we do not know or have not been on this forum for a while, as this info could get into the wrong hands & anyone could steal these bikes without the orginal keys, I have done it twice to a X & R & save the forum members a lot of money with no ECU replacements when they lost all their keys.
