Tamper-proof features are a must. Look for a lock that attaches with tamper-proof screws. These make it near-impossible to remove the lock without a power tool (something few intruders will risk). For additional security, choose a lock that also includes nuts and bolts. These secure the lock by fastening on the inside of the door.
If using a padlock, ensure that both the padlock’s shackle and the lock’s staple are resistant to cutting and sawing. Ideally, look out for components made from hardened steel. This is harder to cut than stainless steel, though can be more prone to corrosion.
If you live by the coast, stainless steel won’t corrode in the salty air.
Particularly for households, the best shed lock is generally a combination lock. These avoid the necessity of having to cut several keys, yet still mean the shed can still be accessed by different people.
With this in mind, I’ve chosen the Sterling 110 mm Locking Bolt as my top-recommended shed lock. It features a combination lock and has a sturdy zinc die-cast body that is corrosion-proof and nearly indestructible. This, alongside its anti-tampering fixing screws, makes it virtually impossible for thieves to gain access.
It can also be positioned either horizontally or vertically, allowing you to use it for gates and cupboards as well as sheds.
