Master LockHeavy Duty Biometric Padlock [Weatherproof] [Fingerprint Lock and Back-Up Directional Lock] [Long Shackle] 4901EURDLHCC - Ideal for outdoor applications, Black

Swapped out an old padlock that basically rusted itself shut outside and picked up one of these Master Locks. Needed something that could actually handle being out in the elements, especially with the non-stop rain we seem to get here. Happy to report it's been absolutely fine, locks and unlocks smoothly every time, no signs of seizing up yet. Feels really sturdy too. Spot on, does the job perfectly.

Great padlock weather and rust proof, Extremely strong.

This lock was frustratingly difficult to open. Scissors were too large to fit through the bar to cut, and not strong enough to cut through the tab that hold the keys. I had to saw the keys free using a knife, which then allowed me to open the lock!I eventually got to use it on the lock-up I am renting, it fits perfectly, and seems to work well. It feels very sturdy, so far so good.

So far, a very sturdy seeming lock. It has a long enough shaft to secure my shed lock and the keys(5 of them) seem uncopiable. Good quality but let's see what happens when it rains or we have some frost. Need a Stanley knife to extract it from the packaging

This is a heavy duty lock and fits the description except i didn't look at the width so doesn't fit into my outside Keter lock up. I will keep it to use elsewhere so money not wasted

Fantastic lock. Doesn't take much effort to open or relocked it and flap to protect key slot is a flap so doesn't jam or stick. So far preferred spending that little bit more to upgrade to this lock for my garden gate than the previous master

Bought to secure some ladder brackets on the wall of the house. It seems to be a nice solid lock, claims to be 10/10 for security level, but more importantly for me is weatherproof as the ladder and brackets are outside on the side of the house, not in a shed or garage.Also, no annoying plastic over the hasp stopping it from getting through the hole on the brackets. So many of the "weatherproof" locks claim to have a hasp the right diameter, but then when you look closer, they've given you the diameter of the metal and not of the plastic covering on top of it so they don't fit. No such issues with this lock, as there's no plastic covering on the hasp, which meant I could buy it relatively safe in the knowledge that it would fit straight away, and it did.

After the disappointment of numerous other cheap locks for a garden gate that rusted or seized up, I settled on this one.The mechanism is smooth. I'm not convinced the rubber flap covering the keyhole is completely weatherproof, it is a bit flimsy. But this is a good lock.So here's a tip if your lock is going to be outside in all weathers:Get a small ziplock bag, and cover the lock with it. Yes, it really is as simple as that. It keeps the rain off, and you won't find yourself cursing at not being able to open the thing.I've done this for two months now in wet autumn conditions – the lock has stayed dry, and is working perfectly.If you don't want to do that and are fed up with 'weatherproof' locks that don't work, buy a marine grade lock instead. There's no guarantee it'll stand up to freezing temperatures, but it should protect against water ingress. I bought one for the second lock on the gate, and covered it with a ziplock bag too. It's stayed dry and still working nicely.
