I want to reset all opening code and start with a new

You didn't say what brand or model, so here's a generic answer:
Find the instructions to reset it to factory codes. Sometimes this is as easy as removing the battery and waiting an hour (or a day) and other times you have to enter special codes, or disconnect a jumper, or connect 2 points with a wire to erase the codes. Once you have the lock reset, put brand new batteries in and follow the instructions for programming a brand new lock.

If you don't have the instructions, you can often find them online by entering the brand and model # into the search box of Google or YouTube along with a word or phrase like "instructions" or "manual" or "getting started."

Only one person is supposed to know your password. When logging in, on that page is a button, forgot password or something like that. Press the button and you will get an email, on the address you gave the site while setting up your account. Follow the instructions in the mail and everything will be ok in just a few minutes.
If you can access your account, goto settings and there change password. Be aware they again ask you current password before you can give in any changes.
If someone hacked your account and did change the settings, you don't get an e-mail, you won't be able to claim the account. You have to setup a new account.

follow this instruction and fix it. God bless you
