Download kies3 in ur PC and connect ur S5 and go to firmware upgrade and initialization than it will ask ur model no. and mobile serial no. (written below battery) enter it and wait till it download files for ur S5 it can be more than 1.5GB after this process ur imei no. will be restored to normal/true vales

Be sure that ur phone battery is more than 70% before doing this

Yes Shri Krishna by kies3 you can restore your phone IMEI no. & S/N no. just follow the steps as I mentioned above
I don't know about relocking, your phone might get locked again ( I don't think so but still there are chances )
better make a nandroid backup of your phone if it is rooted and then copy backup file to you PC in case if your phone gets locked again restore that backup to unlock it

I am happy to help you sir
if u need more assistance msg on AndroidPit

Android Kitkat 4.2.2 is best and I am also using it better
wait for 5.1.1 don't go for 5.0.1 it has many bugs
