Door Lock Pops Out Of Locked Position

My current door lock keeps popping up into the unlocked position and I feel maybe it's time to replace it. When I and/or pets bump the door just a little it pops open. I removed it and the lock snaps fine. Just wanted to make sure it's a match and if there's anything you might tell me about this situation.

I cleaned out the hole punch and it has not popped in over a week. Might ride it out and see what happens. At least now I know where I can get a replacement.

Thanks!
