Tenant locked themself out of the house.

[Brad Spies]

I recently had a tenant lock herself out of her house at 9:30 at night. Luckily, I was available and only live a few miles away to come unlock it for her. Does anyone have a good system in place to deal with this. I’ve talked with our local locksmith in town and they only take calls during normal work hours. Me going over to unlock it even if there is a fee is not ideal to say the least. Any comments would be appreciated!
