Master Lock Universal Trailer Coupler Lock, 389DAT is rated 4.3 out of 5 by 23.
Rated 5 out of 5 by from Master Lock Universal for my pontoons Wonderful company to work with and the product is awesome
Date published: 2020-07-20
Rated 4 out of 5 by from Good for its Price Bought to protect my utility trailer. While it may be removed by several hammer blows (prev. reviewer) that amount of noise will allow me to respond with an addt'l "protection device". Would probably spend 2-3 times more to protect a travel trailer, etc. but this will work for my needs just fine.

can i get keys if i lost mine

Asked by: Ed17
Hello. There should have been a key code stamped on the key. This code can be taken to a local Tractor Supply store to have a new key cut. Please call in advance to ensure this service is available at your location.
