For the failure to open the situation and solutions:

1. There is a problem with the lock cylinder, and it cannot be driven when the handle door lock is pressed down. So the diagonal tongue can't rebound. The solution is to check whether the plunger is easy to use after opening the panel. If it works, then it can be determined that it is a lock core problem.
2. Another possibility is that the diagonal tongue is stuck on the baffle. In fact, it is also a problem with the lock cylinder, but it can be repaired. Try it with a screwdriver. If that doesn't work, you can only change the lock body.
3. There is also a third type. Of course, this possibility is very low, that is, the lock cylinder has a problem. When it is twisted open, the lock cylinder cannot be automatically returned due to being too tight, causing the lock cylinder transmission to fail to rebound, and the slanting tongue Can't stretch out. Try twisting the key a few more times to see if it works. This probability is very small, try the first two first.
