Opening a Door Lock without a Key: Simple Wardrobe-Style Lock Solutions for Lost Keys

Hello,
I have an unusual problem, when I went on a short trip, I locked one room with a key in front of the eyes of the people who looked after the cat that remained in the apartment. I lost the key and I don't want to destroy the door to get to the room ...
A lock is a simple key, similar to those for a wardrobe, how to open something like that? can it be bored or something? I will have to buy a new cartridge anyway ...
I am asking for help and best regards,
Raphael

Such a key

or such

Like the first one, drill the lock. Like the second one, it is a lockpick.

Welcome
If it's a regular lock, try this one

best regards

the latter type of key, only that it was not flat, and had cuts from the top

Could you take a picture of this insert and show it on the forum?
In such cases, I have always reamed the typical inserts.

@ tadkli9743 Your way has worked it is true that I did not pat the nail so nicely, because it is late in the day but I opened it, thank you everyone for your help
Have a good night.
