does anyone try to replace the power/lock button in lumia 520? ... I plan to do it by myself and need some help to get the right decision and tools.

Why is it not working? How that happened? If it suddenly stopped working, did you try removing the battery and putting it in again?

There are several videos on YouTube that will teach you how to disassemble your phone and the tools needed for that. Just YouTube lumia 520 disassembly.
The bitton and the tools can be purchased via eBay or Amazon.

Dont know your exact situation but its a suggestion.. A temporary and instant solution for your problem.. try following apps.. first enable double tap to wake your phone and secondly let this apps lock your phone..
One Touch Lockscreen | Windows Phone Apps+Games Store (India)

in this app you can find "Lock Button" and pin it to home page..

i have this problem too, if your warranty haven't void, i suggest you to send your phone to nearest nokia care around you, you can go to Nokia Lumia 520 - الدعم، التحديثات، التنزيلات وأدلة المستخدم، استكشاف الأعطال وإصلاحها - Nokia - مصر to find it

this happen when i have another external cover putted in, the cover covered the button and causing me need to use more pressure, sometime i pushed too hard, and the wire that handle it has loosen, you can still use it but you need to press it at a different angle

Even I have the same problem . My lock button doesn't work most of the time . So here is what I did
1) To unlock the device , use DOUBLE TAP TO UNLOCK from touch settings
2) To lock the device , use the LOCK SCREEN app from the store .
