My husband has lost the only key he had to his trailer hitch lock. It’s a Master no. 36 is there any way to get a replacement key for this particular lock?

We do have a replacement key for your MasterLock trailer hitch lock. The Replacement Key for MasterLock Coupler Locks # MLK1 is a universal replacement key, all you need to do is type your key number into the "Key Number" box, and a replacement will be sent to you.
