Keys !!

Is it easier to keep all towers of a certain area on the same lock number ?
As most of you know im new to this and currently only have 20 towers and each ahve a diffrent key number ! I can imagine it being quite pricey to put all new locks in each machine can any one suggest any ideas other than individual key tags all in 1 bag lol.

Buy a jailors keyring off ebay, alot easier than keeping them loose, you obviously need a laqbel keyring on each key though. I have one of these for each different round
