Can the old fashioned Panpan security door replace the C level lock cylinder?

It will be different in different periods, you can send a photo and let everyone help you see it.

The most critical thing about the anti-theft door is the lock cylinder, and now the highest civil anti-theft level on the market is the C-level blade lock, you can use Sogou to ask "the anti-theft door lock is broken, want to change the lock cylinder, is there a recommendation?" The picture inside looks more intuitive.

I also read this post, and the Baodi C-level anti-theft lock cylinder I bought, I have been using it for almost half a year, and it is really good. I called the lock picking company, and they said that the lock could not be opened at the moment, so the key should never be locked in the house. There is no way, to prevent theft, the level of prevention must be increased.

Yes, as long as the model is right.
