[Electronics/Car Audio] On Star Police Shut Down
#31
Re: On Star Police Shut Down
EDITED after finding the link below stating using the key fob over the phone does NOT work. This was posted as a one more thing you could try if you were locked out rather than something to rely on. I have not verified if this does or does not work. If I had realized this might be used as a sole method to rely on I probably would have verified on my own before posting. Sorry...
My dad told me had my step mom do this to unlock his 2008 Chevy truck. After reading the link I posted in the following post I realize this may not be possible or I may have misunderstood or may have been something they heard of. When I heard it, I then assumed the fob worked on sound frequency, or some other type of frequency.
Having said that, this is it below...
If you need your doors unlocked and someone can get to your spare keys try this.
1.) Call the person who can get to your keys.
2.) You may have to put your phone on speakerphone.
3.) Have the person with your spare keys hold the key fob to the phone and hit the unlock button.

Unlock Your Car Door with a Cell Phone
Netlore Archive: Locked out of your automobile? According to this forwarded email, you can have someone transmit a signal from your spare remote key via cell phone and unlock your car door in a pinch.

Subject: Unlock your car from the outside!
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.

Analysis: Comforting though it may be to imagine you can unlock your car door in an emergency by receiving a distant signal via your cell phone, it can't possibly work %u2014 not with the technology as it presently stands, at any rate.
Here's why:
Your remote car key operates by sending a weak, encrypted radio signal to a receiver inside the automobile, which in turn activates the door locks.
Since the system works on radio waves, not sound, the only conceivable way a signal from your spare remote could be picked up by one cell phone and relayed to your car's onboard receiver by another would be if both phones were capable of sending and receiving at exactly the same frequency as the remote itself %u2014 which they can't be, given that all remote entry devices operate at frequencies between 300 and 500 MHz, while all mobile phones, by law, operate at 800 MHz and higher.
It's apples vs. oranges, in other words. Your cell phone can no more transmit the type of signal needed to unlock a car door than your remote key is capable of dialing up your Aunt Mary ... though no one can predict what miracles the future may bring.

Re: On Star Police Shut Down
OK, you guys have brought some great information to this thread and I'm convinced now that I do not want my OnStar antennae connected any longer. How do I go about disconnecting it without screwing anything else up? Is the radio antennae routed through the shark fin as well? Any helpful information would be greatly appreciated.
