DIY Series 38: Euro Profile Cylinder Lock

Euro Profile Cylinder Lock (Disassemble & Replacement)

The euro cylinder lock is one of the most commonly used lock profiles by locksmiths and architectural ironmongers since it is so easy to install, modify with additional security measures, or replace; it is seen in both domestic and commercial properties, offering protection and security for a variety of premises and facilities.

Symptoms: 

Unable to open the lock using the key. Suspect the lock mechanism stuck.

First time trying to understand this Euro Profile Cylinder Lock. Found out there are so many types in different dimension. 

This time I bought the parts from local store due to urgency. It is almost double the price.

I can get it online at half of the price or even lower.
