Weatherproof d-lock

Id like to be able to leave a d lock at work. At the back there’s a fence that everyone uses to leave their locks hanging up, which is in between a couple of buildings but not covered. I had an onguard d lock that estates had to angle grind off for me this morning after a night shift, after it being outside in the awful weather over Monday and Tuesday meant it seized up, frustratingly only after I’d unlocked it to get it off the fence then relocked my bike with it.

Can anyone recommend a lock that they leave outside in all conditions that is a bit tougher against the weather? Kryptonite seem to have a slightly different locking system for example – is there one that’s particularly good against water ingress?

Thanks

I left an Onguard lock at work for a few years – cycle shed had a roof but it was still pretty exposed,  I just used to blast it with WD40 or chain lube every couple of months and it survived OK.

Grease. Lots of it.

Definitely NOT onguard IME, you can keep them going with effort and oiling but they’re not built for weather. Awesome value, they do some very useful locks for peanuts but weather is their one failing.

Ah curses securityforbikes are out of shackles for their excellent d-locks (but not out of locking parts!)

Occasional squirt with some cheapo lidl level tin of spray oil keeps the insides functioning smoothly

Another vote against On Guard for this type of usage, the one I left at the station seized with very little warning.

Agree with using the occasional squirt of something to keep them smooth, but I’d go for spray grease, I think you need something heavier than light spray oil.

FWIW my Litelock makes an attempt at protecting the key hole from the elements. But I would still want grease on the moving parts.

My Kryptonite D-lock is (counts on fingers and toes) over 20 years old. I bought it just after they redesigned their lock mechanism so you can’t pick it with a Bic pen lid.

It’s one of the few products I’d buy an identical replacement for without hesitation.

I’ve a cheapy 20 year old Halfords d lock at work, left on the stand. It’s been there 8 years now.. Occasional squirt of WD40 keeps it sweet.

Yah but the nature of the beast is you do it religiously then you think “well it’s working perfectly” and forget about it after a year or two and then it ****s you.

Abus and Kyprtonite seem pretty weather tolerant, my Commuter lives outside 24/7 with a Kryptonite D-lock which is many years old and still works fine.

Surely graphite is better for this application than grease?

I’ve an old Kryptonite New York lock we lock a bench to a block of concrete with in our front garden. Every year or so I check it for release. Every year it’s been OK with a little more grease smeared on any crusty looking bits.

Onguard locks are cheap n nasty. Had two and they both eventually seized up with little to no warning causing slight panic at the rack and that’s with constant use which you’d think would keep them free.
