Question:
Looking at the Trimax King Pen Lock. I have a couple of Questions. It is the key whole drill resistant. Just wondering if someone could drill through the keyhole and unlock the lock. If someone tried to drill the keyhole to try and defeat the lock and damage it to where the key will not work, how would you be able to get the lock off?

Hey Michael, thanks for reaching out, and good question. The Trimax King Pin Lock # TMX36RR is a solid lock, but in full honesty, no lock is completely theft/drill proof. If a thief has the right tools, plus enough time and motivation, they could defeat just about any trailer lock.
With pretty much any keyed trailer lock, if the core was drilled out, the lock would typically release and come off. If someone tried to drill it and it got stuck, you usually wouldn’t have too much trouble finishing the job yourself and getting it off, either by continuing to drill it out or cutting it off if needed. Worst case, it’s more of a removal hassle than being permanently stuck.
I try not to go down that rabbit hole too much though. Typically, a king pin lock that is super visible like the Trimax is enough to deter anyone with any ill intentions. Most theft is about opportunity, and a big, obvious lock like this usually makes someone move on to an easier target. If you want to lock your kingpin, that lock will serve you well and should stop the vast majority of would-be thieves.
If you’re looking for a little extra peace of mind, a lot of guys will pair a king pin lock with something else like wheel chocks, wheel locks or parking in a tighter spot to limit access. It’s all about layering deterrents more than trying to make it completely impossible. Here are some other products you might want to consider:

Where do you usually store the 5th wheel? A driveway, barn, or a shared lot?
