My tip for the day. Locked out of car?

Question

This only applies to cars that can be unlocked by remote button. Should you lock your keys in the car and the spare keys are home.

If some one has access to the spare remote have them telephone you on your cell phone.

Hold your (or anyone's) cell phone about a foot from your car door and have the other person press the unlock button, hold it near the phone.

Your car will unlock. I tried it and it works. Saves someone from having to drive your keys to you. Distance is no object.

Did you know that?

Answer 1

No, it does NOT work! You may have tried it but you discovered that it's a load of rubbish.

Car remotes use one of two technologies to communicate with the car -- radio or infra-red light. Neither of these can be passed over a cell phone or any phone line for that matter.

Phones transmit voice frequencies ONLY. The only way that this could possibly work is if your remote used audio frequencies in the range that phones can transmit, around 100Hz - 2KHz. There are no remote systems for cars that use those frequencies.

So, you know that doesn't work since you tried it and it DID FAIL. Why are you posting such an idiotic comment then? I can only assume that you are a seriously sad case without any semblance of a life -- or you're trying to wind up those readers who are.

Answer 2

Urban legend, wrong, proved so on snopes and myth busters.

See http://www.snopes.com/autos/techno/keyless.asp

This has been around, and wrong, since 2004.

Bottom line is this, cell phones carry audio signals, not radio frequencies. It is a radio signal that unlocks the car, not a sound, so it doesn't work. See http://auto.howstuffworks.com/remote-entry1.htm

Answer 3

BS. Carry a spare key in your wallet.

Answer 4

no i dont think so that will work
it is the actual infra red waves in right frequency
that open the door not the ordinary sounds

Answer 5

Answer 6
