Refrigerator Pickled Eggs

Hello, I am new to pickling and decided to pickle eggs. I used a recipe I found online but when it came to storing the eggs it didn't say whether pr not to let the brine should be hot, warm, or cold when putting the lid on and putting it in the fridge. So, I let my brine get to room temperature before putting the lid on because I am afraid of bacteria growing in the jar. It looks like the lid did not seal though. I can still push the lid popper down and it pops back up. Is this going to ruin the eggs or will they be okay as long as they are stored in the fridge? Thanks.
