Go to the local RV dealer. See if they will give you/let you borrow a 751 key (that’s the most common key).
Man, from reading these responses, most of you seem to think that rvs use legitimate locks.
My rv key also unlocks a storage bldg I bought years before.
Drill it out and install new locks.
Flat screwdriver does the trick. Turns the whole lock.
These are the most easy locks to pick, with a small flathead and a paper clip type thing you should be able to do it, basically just give it a little tension and then rake the pins, jiggling around a bit. I wouldn’t drill it because you can probably just get a replacement key for it online pretty easily.
There is a number engraved on the lock. They are universal.
Find the number, then either borrow or buy a key off amazon for $3
