can i open my iphone with imei

No that number is used by your carrier.

Some use the IMEI or MEID number.

Neither one will help you open the device.

if you can’t get into it you may meet to restore it.

I’d follow this article 

If you forgot the passcode

When you set it up again try restoring from an iCloud backup. If you have it great if not you will need to set it up as new and get sighted back into your accounts. 

Hope that helps
