Storage lockers - 2003 Cobalt 240

[nlmajors]

I have several storage doors that can lock. I did not realize it until one locked behind me and I had to crawl through another to unlock it from the inside. They each have the same handle which it appears to have some method of locking it from the outside (pic attached). Is there a special key out there to fit these and lock them?
