Is there a way to lock bootloader without a computer? I have to send in my phone...

There is an app called boot unlocker. It can relock your device quickly although I'm not sure its what you need since your sending it back

Thank you both for your help. I have managed to lock bootloader but I'm having some trouble trying to restore the phone to stock.
