If the key of the anti theft door is broken, can you still use the broken key?

You can use a broken key with a new one.

When matching the key, the master will fix your broken key in the fixed groove of the mold, to ensure that the broken key is the same as the original good key, minimize the gap of the fracture, and then find the matching new mold key, and the rest will be handed over to the master with the key, and take it home to test whether the anti-theft door can be opened normally. However, it may be a little difficult to use because there is a gap in the middle of the original key. If the key can not open the anti-theft door, you can only find the master to match a handful, try to match a few more, you can save the troublesome process of changing the lock cylinder.

No, the texture of the key is different, and it doesn't work to take the upper half of it, either ask the master to take out the broken key and take it to match, or it is to rematch the lock core.

It's good to go to the place where the key is dispensed, why do you have to send questions online and wait for answers! Some stores have good conditions and equipment, and they can be matched, but if the conditions are not good, you must change the lock cylinder, and the situation is different.

You can find one close to home, and try it when you finish it.
