If you mean you forgot your iPhone Passcode, depending on what you see on the screen see these links:
If you see an iPhone or iPad unavailable message or Security Lockout screen - Apple Support
If you forgot your iPhone passcode, use your Mac or PC to reset it - Apple Support
In either scenario, you will have to erase the device. Hopefully, you've been backing up and can restore it from backup after you get back in. If you haven't backed up, your data is gone.
