Power key for forcing Italian and French CISA RS3/Bricard Chifral cylinders
Text in the video: Cisa RS3. Such a profile. Because profiles may be different. There are different cuts, different profiles. Such a force key. We will test in a situation as close as possible to reality, that is, in the door. Without armor plate, but in the door. RS3 S. We insert it as far as it goes and begin to turn it left and right, pushing the key inward as much as possible. I would also hit it with a hammer a couple of times. The cylinder may burst a little, but for us the most important thing is to turn the lock. You can do a couple of these light blows. Then we continue to move left and right, and press the power key inward as much as possible. It needs to be immersed as deep as possible and then there is less chance that it will break. Already a big backlash. So, well, the lock is turning. Doesn't catch because there's a thumb turn on the back. You can look from the back of the door now. If we have an armored plate, then of course we won’t be able to do this. Therefore, if we have a armor plate, let's just try to use the key from another lock, and the lock will open. The key is stuck. Well, this can be done with a key or something similar. The force key just hasn’t got a little. Of course, in this case we just take out the cylinder, take a screwdriver, and accordingly open the lock . This is the key to another lock. This is the situation with the RS3. We look at our force key, it is slightly bent. Very slightly. But it did its job. Therefore, it is very important to push the force key with this part, here it expands. So it’s better to hit with hammer at least once or twice and it will enter the lock with its thick part. Well, you don’t need to use a lot of force right away. If you put all your weight on it at once, then of course there is a chance that it will burst. Therefore, it is better to rock it, rock it slowly and apply lubricant.
