Inspiron 11 3000 series Security Slot

I recently received my Dell Inspiron 13 7000 and I had the same problem with my Kensington combination lock.

Researching information in the web, it looks like Dell changed the security slot to a shorter one (Noble security Wedge) for some Tablets, Ultrabooks (including Dell XPS 12) and Inspiron 14 (7437) - 7000. There is not information for Dell Inspiron 11 3000 or 13 7000 series but as I can see in some pictures the size of the slot is the same that the Inspiron 14 7000.

The new slot is using Noble security Wedge (Manufacturer Part# : TZ08 | Dell Part# : A6451164) and the link to buy it in Dell store this special security cable is:

I will buy this cable hoping it fits my Dell 13 7000.

The post by jisimonc is correct.

I just purchased a Inspiron 13 7000 last week. Two Dell presales reps said that the standard k-slot lock would work. It did not, but I was able to exchange it for a Noble security wedge, Dell PN A6451164. The Noble lock did work on the Inspiron 13 7000, and I think it also would have worked on the Inspiron 11 3000 I purchased in September. I wasn't able to try it, but the slots looked the same size.

This is not documented at all by Dell, as far as I was able to find. The Nobel wedge lock doesn't list the Inspiron 11 or 13 as a compatible device, and the notebook specs don't list the Nobel wedge as a compatible accessory, or even list what kind of security slot it has. Dell reps also seem to be unaware of this. I'm also disappointed by the selection of Nobel wedges available. I would have preferred a combination lock, but was only able to find a keyed lock.
