hey all?
I was reading some txt yesterday that got me thinking…
If you lock your keys in the car and the spare keys are at home, call
someone at home on their cell phone from your cell phone.
Hold your cell phone about a foot from your car door and have the person at your home press the unlock button, holding it near the mobile phone on their end. Your car will unlock.
Saves someone fro having to drive your keys to you. Distance is no object. You could be hundreds of miles away,
and if you can reach someone who has the other “remote” for your car, you can unlock the doors (or the trunk).
how true is this??? well both use radio signals but different frequencies and how about the modulation and demodulation schemes???
