Review of Thule Accessories and Parts 853-1251

Today we're going to review part number 853-1251. This is the Thule universal change key for Thule locks. This key will allow you to remove your Thule lock with this master change key and replace it with a Thule one key system lock, which we sell separately. This will make all your Thule locks key to like. This will work with all of the Thule one key system locks. Basically I want to show you how this would work is if you have let's say this is a foot pack off of a Thule roof rack.

It already has a lock in it. You have a matching lock cylinder. The number on it is N115, this is a N115. So you want to be able to put this into another Thule product you have on your vehicle. In this case let's say you have, I got an example here of a lock housing for a Thule snug tight hitch lock that you might have.

If you look at it the key says N140. It's a different lock. Instead of having this key and this key you can change it all to the same key basically. You will unlock the lock and then take this universal change key, stick it in, and as you can see it'll remove the locking cylinder. Take the one you want to replace it with, stick it in there, hold it in, pull the key out.

Now it is changed to the N115, which will match that one. You can use this key that works in the roof rack and you can use it to lock your snug tight hitch lock. That's the way this universal change key would work. You can use it to change out locks on any Thule one key system products. That should do it for the review on part number 853-1251, the Thule universal change key for Thule locks..

My locking key can’t be removed in the unlocked position in order to insert universal change lock key. What now?

I would try lightly tapping the back of the key to see if you can loosen it up a little. You might also be able to spray some lubricant into the lock (if you have any openings visible) to try to loosen things up.
