Topbox recommendations

Hi,
I keep breaking the key to my topbox. In fact, the key design is so bad that I managed to break the last one with my fingers, whilst wearing thick padded gloves! I've currently got a Kappa monokey topbox. Has anyone else had this experience with kappa? Any recommendations for alternatives (that use the same mounting plate, ideally)? is Givi any more realiable?

Don't know about comparison to Kappa, but I've used a Givi monokey topbox with no issues. I suspect it's the same mechanism though as they're made in the same factory, I've read.

I stripped mine down and shaved a bit of the locking bit do it locks really easy now. That was 8 years ago after the first key broke after only 6 months. Mines a e45 top box and the locking part could be removed and fettled.

If it is just the key that breaks - probably the red or blue plastic bit coming off the metal - then get a solid metal key cut.
You need a JMA-made BL2 blank, as shown in the pic. My local Timpsons did them for me.
I have done this for all three types of Givi / Kappa boxes I have, and yes they are from the same factory and share badge-engineered designs..

But if the box is not sitting on the plate correctly maybe you are having to force the lock - as marks152 mentions - and you need to adjust the clearances. The rubber supports at the corners can be shaved and the lock staple can be adjusted too, but not easily. Check what is happening and try pushing down on the box towards the plate when locking. You should not need to force the key.

Thanks Steve. I'm afraid not though. It's the key itself that breaks, i.e. part of the key narrows quite a bit after one of the teeth and seems to be a weak spot. One snapped in the lock, then I had a solid key cut and it snapped in my fingers. Maybe I just need a different lock barrel aka different key profile?

I'm not saying it'll sort your issue, but as a general point White Grease really does make "notchy" locking mechanisms run smoothly. Well worth periodically using on bike ignition & pannier locks, plus household locks generally.

I've used givi for 16 years on my FK, never a hint of a problem (well, until a 'Defender' driving phsycho ran into the 45 litre top box, (twice !!!) after which it developed a slight leak.
I then bought a fairly hefty Givi Maxia- 56 litre (to accomodate my new photo bag...) Again, a great box except that, because of its curved shape, it can be a bit difficult getting enough purchase to close it. (be careful not to shut the lid with the keys inside though)

Thoroughly satisfied with Givi build quality....

Sounds like a new barrel is appropriate, but first check clearances etc. as in my second para.

Does the lock work OK when the box is locked when not on the plate? i.e. all you are doing is locking it free-standing as you would if you left it in a room. If that is OK then clearances are the problem, not the lock.

Have you tried to put your box on someone else's plate for comparison? and vice versa?

Sounds like you have a key pattern which is causing the issue.
Key barrel swaps are easy on Givi boxes.
Either a circlip, nut or screw holds barrel in place.

Kappa look very similar browsing images for Kappa lock sets on fleabay.

Suggest a lock change before one of keys breaks in the lock barrel.
