Can I use my own lock?

Yes. However, they need to fit onto our door locks. The ones we sell are the correct size and of a suitable durability. Both contain a hardened steel shackle of either 8mm or 9mm in diameter. If you are bringing your own padlock, please check with us that it is suitable for use.
If however you are renting an 8×8 outdoor unit, these come with locks on the doors with keys supplied to you.
