I've removed many panels over the years as a DIY'er. The plastic clips every manufacturer uses seem to hold the panels slightly less tight after going through a removal/reinstall cycle. I learned early on to replace all of them when you take a panel off. It avoids the worst case scenario of getting a rattle and having to pull it again just to replace one or more clips. Also, they can be rather fragile, so one or more are likely to break when coming off. You need to have a couple spares on hand for that situation anyway.
