Hey @KCRock, so sorry to hear you dropped your bottle and now the lid doesn't lock! It doesn't look like we sell the lids separately here at REI but you can get them directly from GSI Outdoors.
I believe this is the water bottle you have?
If so, here is where you can purchase the lid for that bottle. If that's not the bottle you have let us know and we'll get you to the right lid!
Happy Trails!
At REI, we believe a life outdoors is a life well-lived.
