For your trailer tongue lock part # 379DAT the correct part number for a replacement key is the part # MLK1. But you will need to know what key number you need. If you do not know what key number is needed there is no way to know.

How many key numbers are there? I am in the same situation. Is there a master key?

@CarltonP There's a couple hundred different key numbers and no there isn't a master key. If you don't have the key number written down it's going to be best to replace the padlock.
