Missing Keycard

I’ve been working in OGP for about 3 months now and every day when I clock out, I make sure to put my keycard back in the key box. Today I went to check out a keycard and I was not allowed to grab one because apparently I forgot to put my card back after my last shift, I was almost certain I remembered to put it back the last time I worked but apparently I didn’t. I looked all over in my home and car to make sure I didn’t take it home on accident but I still can’t find it. I don’t work again for another two days but should I tell management about the issue or just wait until my next shift and ask my team lead? Update: It was just put in the wrong slot by me and that’s what caused me being locked out so it’s all been resolved. Thanks for the advice!
