Comment faire pour déverrouiller et verrouiller mon Xperia E5 à l aide des touches sonores ? 

How can I unlock and lock my Xperia E5 with the audible keys?

Hi @Nana05, sorry to hear about your power button not working.

I have translated your question to English as this is an International forum, please post any replies in English and will be easier for me and other users to assist you.

There is no setting in the device that will remap the volume keys to work as a power button, but there may be applications that can do this in the Google Play store, so if you haven't taken a look there, do so!

To have your device repaired, get in touch with your Local support team and they will arrange a repair for you and answer any questions that you may have regarding warranty, local service routines and consumer laws.

I hope that helps!
