Something that has been bugging me for a while: the key itself doesn't open/close/lock anymore like it used to... I asked my dealer about this, he said many people have this issue and Duc is unable to solve... they recommend buying a new fob; that irritated me.

So, handy as I am (ahum), I started messing with it and managed to repair it; it's working once again like it was when brand new! Let me share a 10-step procedure:

Step 1: open the fob with a coin or a screwdriver; this separates the two black halves
Step 2: remove the spring-lock thingie by unscrewing the two black screws (gently, don't lose the screws)
Step 3: take out the spring
Step 4: blow (yes, with your mouth is ok) to remove dust/dirt and metal shavings
Step 5: put the key itself in 'open' position (180° rotation compared to closed and hidden inside the fob)
Step 6: put the spring back inside the opening (the hollow inside the button), the long pointy end (see RED arrow) of the spring aimed 180° away from the key itself: it 'locks' inside the push button, so it has to be either 0° or 180° anyway, and at 0° it doesn't work
Step 7: take the mechanism thingie (from step 2) and put it carefully back in place: the centre (see BLUE arrow)will slide exactly inside the spring and the spring's pointy end will fit inside the cut-out facing the same direction (see RED arrow again)
Step 8: put the 2 black screws back in, fasten them very well
--> you can already test the spring mechanism, it will work
Step 9: click the two black halves of the fob together again
Step 10: happy bunny again

I'll try to upload pics...

thx ;)

By the way: apparently the spring mechanism can fail in several ways, causing various symptoms... in my case the button didn't work anymore to 'open' the key... some people report that they can no longer flip the key back inside the fob at all (having to keep the flipped-open key in a pocket), some just say it won't stick to the 90° position (e.g. for opening the fuel cap) anymore. If you have similar issues, try this fix... if it helps, you'll be happy; if it doesn't help, you only lost 3 minutes of your time.

now now, first see if it actually works for other people before getting carried away here ;)

That being said: I never had any 'functional' issues with the key fob... when going out on a bike with a traditional key, it somehow feels weird now...

I had to go through all this when I got my new fob, dealer doesn't have the tool to cut the key, so i transferred the key part into the body of the new fob. You can also wind the spring a bit tighter, makes the key open with more snap. Break the spring if you overdo it.

I know this is an older thread, but I had the lazy spring issue and followed these instructions to fix my key just now. I have an additional step that makes the key work like new. On step 6 above, DO NOT point the "long pointy end" 180* from the key, rather point it right in line with the key. Then take the "mechanism thingie" and put it on top of the spring 180* (clockwise) away from where it is screwed down, rotate it counterclockwise 180* into place and screw down. This creates a very nice tension on the spring allowing the key to pop out like the day you picked up your Diavel.
