First key has never really been an issue. It is the second key that you can't get if you choose wrong path in a questWe have added one more thing to this update, the first key can now be found in the premium chest and sold on the market. This should help some players get their golden gun.
Are there any plans to add another possibility to obtain the second key? As far as I know, there is only one other way to get the key after choosing a different reward in 'The raid', which happened here and there in the early days when the 'Gentleman's set' was top notch and the use of the key was still unclear . That is, you have to be lucky in opening premium chests. At a price of 1500 nuggets/bonds each and a chance to find the key at around 0.55% (tw-clac.net) you have to spend more than 250,000 nuggets/bonds in average to get one.First key has never really been an issue.
