Many thanks Doug, i'll take a lookJacobs is a brand name so they’ll have manufactured many sizes of chuck with different keys, usually there is a code on the chuck itself which you can google to see what size key you need.
Hi Doug, sorry to bother you with this question again... the code on my M2 chuck says 16mm JT6 but i can't find a key for that, only K3 C3 !! Do you think this one will work.... thanks...... 16mm Chuck Key 11 Teeth Rubber Coated 3-16mm Drill Chuck To Fit Jacobs K3 C3 | eBayJacobs is a brand name so they’ll have manufactured many sizes of chuck with different keys, usually there is a code on the chuck itself which you can google to see what size key you need.
Thanks a lot, the 11 teeth seem to be the 'key' here... Some are 13 !Was in the same boat just a week ago, lost a key to my 16mm Chuck. What made it worse is that the chuck had no markings on it apart from "16mm" (both m in capitals!!!)
Ordered the 4 way Chuck on Amazon, none of them fit, all were small.
Then I ordered this, perfect fit and quick delivery from this seller on amazon.

Hope this helps.
Also string/wire would have helped, i've just ordered some magnets to help glue my life together, looking forward to a future where small metal things are safe.Following all of this, realizing there are more varieties than I thought possible, I have resolved that:
- I will measure all of my chuck keys and count the teeth
- I will write this information on a sticker and stick the sticker to the tool/machine to which it relates
- I will do this now before I lose any chuck keys
