Incorrect !
The 3u114 is not the lock the 3U pick was made for, the 3U pick was made for the 3U115 lock, the non bs , as the make up key is made to the Number 6 height, therefore unless you have the make up key machined down to the No7 height and introduce a new row of pins for the No6 height, it cannot pick a Chubb 3U114 with a number 7 lever in it.
so the 3U kit although handy isnt the tool for this lock, the union kit is the one, as the 3U and the union 2134 are the same lock, just tighter curtain, worth noting that the union kit struggles on some of the older 3U locks as the curtains are too tight.
