Chastity and orgasm denial discussion

Does anyone have any tips on unjamming a master padlock? The key turns about 1/4. Used enough force to bend one of the keys and stopped. Have some masterlock oil in the mail. It goes through a stainless steel cage thru my PA, no play or wiggle room so i dont see how it could be cut off safely. At least its not causing any discomfort. The lock is brand new and has only been on for 2 weeks without a key being in it.
