I entered a new password for the app lockbox and when i opened all saved password were garbeled. what can I do?

You probably need to connect to your new wireless router.

Open the Alexa app.
In the Alexa app, open the left navigation panel and then select Settings.
Select your device and then select Update Wi-Fi. If you're adding a new device to your account, select Set up a new device instead.
On your Echo device, press and hold the Action button for five seconds. The light ring changes to orange, and your mobile device connects to your Echo device. A list of available Wi-Fi networks appear in the app.
Note: The Alexa app may ask you to manually connect your device to your Echo device through your Wi-Fi settings.
Select your Wi-Fi network and enter the network password (if required). If you don't see your Wi-Fi network, scroll down and select Add a Network (for hidden networks) or Rescan.
Optional - Save your Wi-Fi password to Amazon: Any Wi-Fi passwords saved during setup automatically appear when you connect a new Alexa device to the same Wi-Fi network. The password is also remembered if you switch between saved Wi-Fi networks. For more information, go to Saving Your Wi-Fi Passwords to Amazon FAQs.
Optional - Connect to a public network: Enter any required information if you are connecting to a public network that requires a web browser to sign in, like a school or hotel. The information could be a pre-shared password, room number, or just a button to accept conditions for using the network. This information cannot be saved to Amazon. Contact the network owner for more information.
Select Connect. After your device connects to your Wi-Fi network, a confirmation message appears in the app.

and win, every time.

My wife and I experienced the exact same problem yesterday with Lockbox. The only explanation I have is that I just recently updated the IOS software, but really don't know why this happened. I was able to fix it doing a "restore" from an iTunes backup I had done for both phones just 4 days earlier. The app works again and all information was restored. This should work for you as well and hopefully you have done a recent backup of your phone because you will lose things on a restore that occurred after the last backup (e.g. photos, calendar entries, notes other app information, etc.). If your last backup was a while ago, you should probably first try to transfer or identify some of your more recent photos and things so you can save or reload those things. Good luck!

Try changing your password back to the old number and it should hopefully unscramble.
