Following on from my previous post about things mobile phones can do, I finally met with some friends yesterday and tried to unlock my car by sending the signal from my mobile to my friends mobile to the car.
I was in the house totally ought of sight and reach of the car and phoned my mate who was about 1 foot from my car. I pressed the unlock button and hey presto...opensesame! I then locked the car the same way and successfully done it all over again too make sure.
I should add that it only worked when the traffic was quiet, the interference created by the surrounding noise seems to get in the way. So anyway, there you have it. If you are locked out of your car and are miles from home, get someone to unlock it via your mobile from wherever the spare key is and you're back in business! I just realised, we could have tested it by going from landline to mobile as well, oh well, I'll do that another time.
Hardare used in the test were:
1 2003 VW Polo and key fob
1 LG KG 810 mobile handset
1 Sony Ericson mobile handset
