Replacement Locks for Under-Coach Storage Compartments

Later this year, we will full-timing in an urban RV park and by necessity will have our under-coach storage compartment full of needed items, some relatively expensive. I have been looking into more secure locks for those compartment doors and have found that, as I suspected, they are all the same, with only a few different keys.

Is there any way to make those compartments more secure? Some different type of lock? Obviously having the existing ones re-keyed is not the answer.

Thanks.
