If you are looking for a good locksmith, then I advise you these guys https://door-repair-toronto.ca . I contacted them once, I urgently needed their help. They arrived very quickly, they arrived with all the necessary tools, they worked very carefully. They were able to fix my door so I didn't need to change the lock. I'm very pleased with their work and recommend them to friends.
A locksmith turns out to be rather expensive (I don't know about other countries but in Boston, America his work's gonna cost you a lot), so that's why sometimes it's better to do some personal involvement. Once my lock to the barn got rusty, I just melted it with that cool device - https://finderiko.com/laser-cutter. No lock, no problems, right?
