Look at what kind of door you are Wang Li, the community is bought in batches, the lock cylinder on the market can be universal, ordinary cheap, if it is a retail door bought by Wang Li store, it is difficult to buy the lock cylinder in the market, and the price is expensive.
Wang Li, change the lock cylinder 180 and upgrade the blade 380It also depends on the lock model of your door.
At present, the lock cylinder level is B-level and C-level, and the high-end is the fingerprint password.
You can find a local lock store, they can help you change it, and you can ask about the anti-theft level of their locks, the higher the anti-theft level, the more expensive the price. But you have to bargain, the spread is too high.
Now the locks are separated by the lock cylinder, that is, you only need to change the lock cylinder, as for the unlocking is not in place, that is, the lock cylinder is not installed, and the lock cylinder shrapnel is not the right lock cylinder gap! There are screws on the side of the lock to adjust, loosen a little, and then knock it back and forth a little, test the sensitivity with the handle, and then use the key to open it, and then tighten the screw.
