I haven’t tried this yet so I don’t know if it’s true. If it is…it’s good stuff to know.
If you ever lock your keys in the car and your spare is at home, call someone on your cellphone and have them get the spare set. But instead of driving to wherever you had your brain poot, have them hold the spare set next to the phone. You hold your cell phone pointed at your car and have them press the unlock button.
I’m told the magical beep your remote emits will travel over the cell phone waves and unlock your car.
Don’t know if this works…but I’m anxious to try it.
