Every so often I get in a hurry and accidently lock my keys in my car. What a pain that can be. Some people don't go all out with their car insurance. So unfortunately to have someone come and get the door open, its not covered and its going to cost them some money.
Through my cell phone company, which is AT&T, they give you an option to get roadside assistance put on any of your lines. Let me tell you, that was one of the smartest things I have done with my cell phone.
With roadside assistance on AT&T you get some good coverage that really come in handy. If you lock your keys in your car they will locate you and send a person from your area to get you back in to your car.
Along with that you also get tow service when you need it, if you run out of gas they will send someone to bring you gas, and if you get a flat tire they will come and put on a spare. If you or anyone you know has roadside assistance on your phone I would recommend giving the phone company a call and checking it out!
