Guardian Trailer Locks

Hope maybe someone around the Tulsa area can help me out. Does anyone know if Guardian Hitch / Lock company is still in business in the Tulsa area. I have a Guardian lock for my boat trailer and I'm having a hard time locating a replacement key. I've called the number listed on their website (918) 249-8521 several times and do not get an answer. Maybe someone knows a better way to get in touch with them.

Why not just drop them a letter in the mail along with your phone number so they can contact you........that is, if they're still in business.
