I read this at Texas RV Travel Blog.
Does your car have remote keyless entry? If you lock your keys In the car and the spare keys are at home, call someone at home from your cell to their cell. Hold your cell phone about a foot from your car door and have the person at your home press the unlock button while holding the clicker close to their cell phone. The car will unlock.
Is that REALLY for real? Does that really work?! It blows my mind! I am itching, absolutely itching, to try it out. I guess I’d have to get a car with remote keyless entry first, though, right? :-p Someday maybe! :D
I’m a married mom with 4 kids. We live in Upstate New York in an old 1855 house with our five pets (yes, five, *sigh*). Life is never dull, and exciting things just seem to always happen to me... why me... when I'm not running around the house fixing things, I do freelance writing and blogging. My work and opinions have appeared in Salon.com, USAToday, eHow.com, iMedia.com, the Associated Press and I've even been interviewed by TIME and The Wall Street Journal about blogging. Can you believe it?! Here is where I express my zany, creative, motherly side.

Hey, thanks for the link! It did sound a little too good to be true.

I’ve actually heard this really works. Totally amazing.

Yes, I’m itching to find out too. That’s something incredible. The remedy is to carry a spare key in our wallet or pocket to preclude this eventuality. Thanks for the incredible post. God bless.
