I have a padlock for my outdoor bike shed. In two years I've got through 2 of them. It is of the type pictured.
They have both jammed in different ways, but ultimately I need something that survives all weathers better.
What can you recommend for a UK based user, Convenience is key. Especially, since the shed is opened and closed at least 4 times a day!
The shed can be found here: https://www.shedstore.co.uk/6x3-trimetals-metal-bike-shed-anthracite
And the locking setup is like so (the silver bar swings up for the shed to open)
Final solution
Resorted to cutting a plastic bottle to cover the lock, and it works brilliantly, don't know why it took all the suggestions to do it!
