King pin lock deters towaway theft of your fifth-wheel trailer. Heavy-duty aluminum collar fits around your trailer's king pin and secures with the chrome-plated, pick-proof steel lock. Can be keyed alike to match other etrailer locks.The lock was very easy to install! I received the original lock minus a key. I made a call and spoke to Neil, and had another order issued for a replacement lock and received within a week. I am very happy with the product and the service that etrailer provided.
Perfect. Fits right into the slot on the kingpin. It will be a good deterrent for the not so good doers to move on
It works as it should. Not a whole lot to complain about. The locking mechanism itself is a little strange in that once you insert the key you have to use the key to unscrew the lock, it's not just a twist and unlock. You have to use the key to thread the locking end off and on. A bit odd.
Fits well, does the job just like it is advertised to do.Extra protection in today's crazy world
Fits great, seems to fill the bill perfectly. Sure adds a degree of comfort when I leave my trailer unattended for a while.

Same as before. Still like it. While you cant ever stop the committed criminal, this does add the level of complexity that may dissuade them.
Well made, easy to take on and off. Gives me peace of mind knowing that someone can’t hook up to my trailer and take off with it. It’s part of my routine wither at home or traveling it goes on when I’m set up.
Fits very snug. I help with peace of mind with all of the thieves these days. The unit attaches securely to the king pin. It will slow someone down.
So far so good for our new 5’er. Little weird how you have to turn key (around - around) to undo the lock but will get use to it.
Have not used it yet, but it looks strong and dependable.
I will let you know if I have any problems.
Good quality and fit. Easy to use

Great, with all the trailers of all kinds being stolen lately this product has protected my personal property!
The King pin lock was exactly what I needed to feel secure with my 5th Wheel. I ordered the King Pin Lock and came quickly and the price was best. I have since sold my 5th wheel with the lock. Thank you etrailer.com for make my purchase easy.
Great product for peace of mind, especially when you have your trailer at a storage lot!
This device will not sit deeply enough on our pin to allow the locking pi to be inserted. Maybe the weld fillet on the pin "cap" is to large.

I will have Customer Service reach out to you. If you can send us a picture of the lock and pin we can see what the issue is.
Love it. Use it as a theft deterrent on a ag trailer, that uses a hitch pin.
Pair of matching key coupler locks. Great product
Easy to use with simple but effective design. Great price.
I was in search for a way to secure my fifth wheel and found etrailer.com and found just what I was looking for.
The product works great and was shipped quickly and the price was right as well.
Thank you etrailer.com as I will purchase from you again if I am in need of anything else for my camper.
Got it on time. Seems like a quality item. The key is actually a screw driver and not a key in the traditional sense. It’s a screw on lock. There should have been directions so that I didn’t spend 5 minutes wondering why turning the key 1/2 way didn’t unlock the device.
5th Wheel King Pin Lock arrived and I must say it is exactly as described on your site. Fits perfectly and the lock is heavy duty.
This lock appears to be of top quality. The locking bar is thick the full length of the bar. Not like some that are thin where the lock attaches. Should not be able to use a pipe to pry and snap the lock part off like can be done with cheap hitch ball type locks.Another thing is the key lock is very unique. If you give someone the key they probably will not figure out how it actually works. Good thing I read the directions. Overall I am impressed.
eTrailer is the best to work with! I called and had the privilege to work with Michelle S. She really knew her business and inventory. I needed a certain type of lock that matched the existing locks I've had for years. eTrailer made that happen with matching keys! The order was placed quick and my parts arrived withing days. To get this type of service, for quality products priced this low, is very rare these days!
GREAT product. My personal locksmith friend thought this was a brilliant product given he didn't know how to open until I showed him the "unscrewing part". I recommend that to everyone as an additional deterrent for your king pin lock needs!
E-Trailer is the best company for RVers, my sales person Hally C , was helpful, processed my order quickly and i received my order a day sooner.
E-Trailer has everything an RV owner would need,
if you need to order from E-Trailer please ask for Hally C.
the pin lock above is what i ordered, an to hold it in my hand it is so much better then the photo . if you buy from any other supply company you are making a mistake..
E-Trailer all the way and never look back .
I use this pin lock with my fifth wheel trailer used in the UK. Works perfectly. It is a requirement of my insurance to have a pin lock and this fits the bill. I always carry some disposable gloves as otherwise you can't avoid the grease when fitting and removing. Overall an excellent product.
