A hide-a-key is only good if you put it back after you have to use it. Just learn this morning that my wife who is in Greenville this weekend locked her keys in the car at a convenient gas station. She'd used the hide-a-key to gain entrance sometime last week that I was unaware of. Short version.. It cost $45 (after hours) to get someone to come and open the door. I am glad she did not have to call an HVAC company.
