Question:

Greetings, I have an older Master lock like the ML 377KA. Its not been on a trailer in several years and now I have misplaced or lost the keys. Im assuming it should still be functional. Where can I send the lock assembly to get replacement keys? Thank you, in advance for your assistance.

Without having a key or the key code for your Master Lock 1-7/8", 2", and 2-5/16" Trailer Coupler Lock # ML377KA your only option would be to contact a local locksmith. There is no guarantee they will be able to create a replacement key or replace the lock cylinder but you will need to discuss this option with them directly.
