First thoughts Looks like a euro or Thule key used ..very common
Cut the Thule and euro keys for many years and stood out straight away
Here's a better pick Of one Atlas deso and used for oil tanks locking lids .
Deso lock possible Euro / Thule cam lock.
The pics
Deso lock code 196
https://imgur.com/a/NXYzmVEUsually card 383 and usually coded keys 001 to 200
Space 161 256 350 445 539 in inch
Depth 0 . 268 1 . 205. 2 . 142 But looks too deep so would need to cut a key
Thoughts.
The one I've seen in pic I've posted up as code 196 looks like It does not match Series (but Sold on website)
But would need to see more to make a decision ..on the codes for atlas deso
If your asking what the Deso atlas 196 key is sold on the website
It's in photo above. 01222 is my First guess.... is it there master key maybe .
The Thule 196 being cut 12222 fyi .
Have they removed a wafer on this lock by any chance to a 4 wafer cut X0111
On a blank SILCA BT2 i'd cut 1110 from Tip then on same key 22210 From tip to try on a 196 code .
After that it's looking at the Blau cards 125 , 328 ,736 depths and space lol.

You do not need to remove the lock on many Thule cylinders as core removes real easy in unlocked position
With a blank key .. shoulders filed back.
not saying this will be the same but usually held in place by a ( locking 6 wafer that needs lifting ).
But nothing to report on the code software ..for years us locksmiths have had to reverse engineer
Keys purchased and brought to us for depth and space info .
No one likes to share the info after theyve got it ..last week I received a few hepco and Becker keys from Germany
To do exactly this and was completely wrong as to what I'd thought they where ..now I know so happy days
Till next week .ROFL
