DaveM Report post Posted January 19, 2010 Just as I suspected. 1. If you lock your keys in the car accidentally you can unlock it (if you know the code)2. You can allow others to enter your car without giving them the key. Works great for kids.3. You can leave your keys in the car when swimming, hiking or going to an amusement park or doing anything where you don't want to have keys in your pocket.4. You can lock (and unlock) the door while leaving the keys in the ignition and the car runningNumber 4 is against the law in most places plus if a thief breaks the window and drives away your insurance won't pay.
