I am not clear on the idea of 'button lock'. Will the button lock prevent the user from accidentally pushing down the button ( like in a backpack)?

Yes it should be fine, but maybe test it out with just water in it first. The button creates a pretty good seal and not easy to accidently push.

There is not a locking mechanism, though a pretty significant amount of force is required to engage the spring. It won't open from jostling in your pocket.

You have to push the button. But I have not liked this clock. When I pack it, the buttons are too exposed and either turn the backlight on that kills the battery or changes the settings. There is no lock-out button.

I like the case. It's really sturdy and protective. For a guy who's putting it in the pocket, it is pretty bulky, though. I don't even know that you need a case for the problem you're having, though. It's locks automatically within a few seconds of your last stroke and must be unlocked by pushing a side button for a couple seconds. Hope that answered your question.

You have to press the button and lock it. It does not have the automatic locking feature.

Yes you can depending on how you out it in case. If you don't want to access it in case you can turn it around so button is blocked.

Locks inside with a button. Does not unlock sutomatically; you have to turn the button.

No. You don't need to hold the IS button down. You just need to push down once and it will work for 5 minutes and then it will automatically turn off.

I don't think so. It takes concerted pressure to push the button down about an inch

If you mean a tiny padlock to keep someone from opening it, then it's yes. The case has two zipper controls that when closed together could be locked with a very small padlock.

It clicks shut but not opening on its own unless the button is pushed accidentally. It has leaked in my daughters backpack but that is only because she didn't lock it shut. We've used these since she was in Kinder and is now going into 5th grade.

Yes it locks great! There is a little button on top that you push down. Locks and unlocks very easily!

We have not had any accidental button push. Mom puts in in her purse and it bounces around all day. No issues.

Dear Sara. I bought it for my wife a "coon's age" ago. We've never used it (but I'm sure there is no lock). You just depress the top button to use. Sorry, can't help much.

No, but the button is flush with the screen. It is hard to accidentally push.

It has a hold feature on it, that keeps you from accidentally changing any of the settings. If that's not what you need to know, describe what you mean by "lock" and I'll try again to answer your question.

Hold the button down and it will lock in place. Release lock by repressing button
