Faulty bike lock - what is reasonable

[kiethton]

The lock that secures my bike outside the flat seems to have stopped working this morning (key and all spares turn half way but not beyond) leaving me on the train.

The lock and chain are about 6 weeks old so will be returned to the big jungle but the other issue is actually removing the thing. Is it reasonable to assume that they will refund the cost of a locksmith removing it as well? If not would claiming this direct cost be a lost cause?

Thanks for that all, makes sense.

Is it something that Robert Dyas would sell? If not I'm likely to just WD40 it and get it sent back for a refund - always seemed a bit temperamental/st (Oxford HD)

Thanks for all the pointers guys, got it unlocked that evening with some lube as advised.

Think this'll be an added job alongside the chain lube/tighten and checks when I do them.
