Where can I buy the valve key (one valve per household) above the heating pipe?

1. You'd better find the supplier of this valve and see if you can match this key.

2. If not, replace the valve.

3. Go to the hardware store or the after-sales service department of the valve supplier.

You can knock off the lock. Buy the lock yourself and change it yourself.

For reference.
