I have a Decathlon cable lock which was cheaper and has a fairly solid key. This however has a very thin key. As a result the key bent and snapped off in the lock on the second use.
I'm sorry to read that the lock has snapped on this lock. Please return it to us for a refund or an exchange.

Great item awsome price
I’d have to recommend you buy a bigger lock for mountain bikes.
