I was out in the shed getting the shop-vac, and when I walked past her car, the panic-button alarm started beeping and the lights flashing. I went inside and was prepared to meet a hysterically laughing wife, but she was upstairs, and both sets of keys for her car were in the kitchen on the hook. She never pushed the button. I cancelled the alarm with the fob. She didn't do it. She thought I did it. Could someone in town possibly have a device running the same RF?
