Higher security locks?

[mlts22-HILO]

With a Hi-Lo trailer, I'm wondering what type of lock is present on the main door. The reason for this is that some trailer locks that I've seen tend to be easily picked, while others will actually take some effort (and more risk of getting caught.)

Are there high security locks available for Hi-Los, by chance? Please excuse the dumb questions.

Hi-Lo's come with a dual lock. One is the standard lock on the door handle and there is also a keyed dead bolt lock. One key handles both locks.
