Keys Locked In Car? Use A Cell Phone.
OK. This is not a litigation technology good or service, but even people in our industry can be unlucky enough to lock the keys in the car.
If you have keyless entry fob, you push a button, a signal goes out and the car unlocks. That same signal can travel over your cell phone. Subsequently, if you have an extra fob at home, miles away, have someone there unlock your car via the phone.
How handy is that?
I tried this out myself.
