What should I do if the key falls into the elevator gap and the property doesn't help me find it?

If the key falls into the gap of the elevator, you should first contact the property or elevator maintenance personnel immediately, inform them of the situation and ask them to help find it.

If this property doesn't help you find it, you can try the following methods:

1. Contact elevator maintenance personnel: You can try to contact professional elevator maintenance personnel who have the experience and technology to find and take out the key.

2. Seek help from other tenants: Ask other tenants if they have similar experiences, or seek their help to find the key together.

3. Buy a magnet yourself: consider buying a magnet, tie it with a rope, and put it at the bottom of the elevator or in the gap to see if you can suck out the key.

No matter what method you take, you should pay attention to safety. Don't try to enter the elevator equipment by yourself or try to dismantle the elevator, so as not to cause more trouble or danger.
