Try this
- Check that each person can access the home if you return at different times.
- Agree on an appropriate fallback for a lost key without publishing access details. Do not rely solely on one phone being charged and answered.
A worked example
“We should each take a key in case our plans diverge.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
Avoid leaving one person dependent on a phone response to get home.
