So I was just wondering if anyone else has had any problems similar to mine.

Last year I bought a evo series 4, and several months later it jammed. I took it back to the shop I purchased it from, they inspected it and said it was faulty or something and replaced it. Fast forward several more months, second series 4 jams. I take it back to the same shop and they say there is no visible reason it should be jamming and upgrade me to a New York u-lock (this was Novemeberish). Fast forwrd to today, and my stinking New York u-lock is jamming.

My bike sleeps inside and is stored inside any time I am at my apt for more than an hour, and ALWAYS if I am home and it is raining/snowing. My lock rides inside my bag anytime I have one or In my waistband, and has never been mounted on the frame so it has never been subjected to road spray. The only time the bike and lock are outside in rain or snow is when I am in class, and classes are only 1.5 hrs or 3 hrs, and when it is raining or snowing I try to lock to the covered racks as often as I can.

(Oh and another fun fact...I bought a series 4 for my brother and he had it jam up on him in several months as well and had his bike stolen while going to get the lock serviced)

Anyone fed up with Kryptonite too? Have any tips on keeping it from jamming?

Is there a lock brand out there that can offer the protection of a New York U-lock? Cause I think I'm done with Craptonite locks all together after this


edit: in all instances key inserts cleanly and has clean action while turning
