Lock Lubricants
Graphite, WD-40, and KPL
We all know locks wear out. There are things we can do to limit the degradation of our locks. One of those things is regular lubrication and cleaning. There are several options when it comes to lock lubrication and cleaning. The main contenders being Graphite, WD-40, and KPL. There are some distinct differences between them, some you should use, some you should avoid at all costs.
Graphite
Right out of the gate weโre going to knock down this horrible product. Okay, itโs not THAT bad. However, in high humidity climates, like the West Coast of Canada, itโs awful. Imagine putting gritty wet sand inside your lock. Thatโs graphite. When used in a high humidity climate it clumps up, and gunks up your lock worse than before. Some locks have a higher tolerance for this, such as a WR5 keyway from Weiser. In something like a Weiser SmartKey though, youโve pretty much just bricked your lock.
WD-40
Ah, good olโ WD-40. It makes things move. Itโs not a lubricant though. WD-40 is a penetrating oil, so it will make your lock move because it will remove the crap clogging up your lock. However, once it dries up youโre going to be left with metal on metal friction. Youโll need to follow up with a real lubricant.
KPL
KPL, which stands for Knife Pivot Lube, is wonderful. Originally designed to bring life back to a folding knife. Weโve discovered it also works great for your locks. Best of all, because itโs intended for use on a knife, itโs non-toxic. Which is great because just like a knife, youโll be touching your keys a lot.

How We Perform Lock Maintenance
First, we take your lock apart, this means removing it from the door and entirely disassembling it. Once entirely disassembled, we clean each piece of the lock with WD-40, removing any built-up grime. We then dry the excess WD-40 with a shop towel, and apply a liberal dose of KPL. Once reassembled, we put a few more drops of KPL down the keyway and spin the lock a few times with the key. Ideally this should be done once a year.
