How to Find a the Lock Number to Choose a Replacement for H&H Door Key

Question:

I found the CH545 key on your website. Are all HandH doors keyed the same? How do I know which key fits? I just bought this trailer and I dont have a key to match or copy. thanks.

So, most small locks with round cylinders have numbers on them somewhere- usually they're on the face of the lock, but they can also be found on the backs or imprinted on the internal lock cylinder themselves. If they have these numbers, they're going to have a standard key that will work on all of the locks with that number tag.

The Redline Replacement Key # CHK545 will work on all #545 locks. If you can check the trailer lock and see if it has a number imprinted on it anywhere, that will tell you which key can be used to replace it. You may need to disassemble the door latch to get to where you can see the lock cylinder and check the number-depending on which type of RV door latch you've got. The other alternative would be to replace your door latches with something like the Global Link RV Entry Door Locking Latch # 295-000019 which has the option of matching all the latches you replace with locks and keys that match. This will make it so you only need 1 key to open all of your doors.

If you want to go that route, send me a picture of your entry door latch and I can recommend a replacement kit.
