Hey Marc, thanks for reaching out. Yes, we can provide a key for that. What you'll need is the following:
- Replacement Key for MasterLock Coupler Locks # MLK1
I'll just need you to provide your key number. When you go to the part page for the MLK1, there is a box where you can enter your key number. Just enter that number in the box before adding the key to your cart. That will get you a matched key to go with your lock.
What do you use the lock for?
