unlocking your car thru the cellphone??

[geez]

just read this from a forwarded message sa email entitled "things you never knew your nokia cellphone could do". the statement below made me think...possible ba talaga? has anybody tried this!?:innocent:
incidentally this is my first post

II*
* Subject: Have you locked your keys in the car? Does you car have remote keys?*

This may come in handy someday. Good reason to own a cell phone:
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 from 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).

Editor's Note: *It works fine! We tried it out and it unlocked our car over a cell phone!"*

according to other people in this forum, it doesn't work.

haven't tried it personally though, but I figured that the signal carried by the remote won't be able to piggyback through the signal transmitted by a cellphone.

Hmmm, my friends and I tried it when we were in Tagaytay 2weeks ago, and it worked with their cars. It didn't work right away though, you'd have to work with positioning the phone at the right spot for the alarm to pick up the signal.

Really? So how do you "position" the phone?

wow ok po a, pwede po pala yan! i heard it before pero then i believe myth lang sya imo, pano po ba ang positioning ng phone to the car para ma-receive nya yung signal nung keyless remote?

if possible naman po bka meron pong pic or video demos para mas maintindihan po. thanks po

This is the item in that thread which I am most interested.

Can you share us how you did it?

Haven't tried it though myself. This provides some degree of encouragement.

and also what car kaya ito?

hmm...maybe it also depends on how strong the signal is? baka sa sobrang trial and error sa positioning ay patay ka naman sa billing ng cellphone

paki post nyo na rin po kung anong specific brand ng mga keyless car security ang pwede using this method (e.g. Code Alarm, Clifford, Toyota OEM, Honda OEM, etc.) thanks po

hard to belive that it can actually work. we should asked the Mythbusters to try this out. if they havent already.

trial and error nga in trying to get the car to recieve the signal from the phone. the cars were a 05' sentra and 99' civic.

regarding infrared, though i am no expert, i think infrared requires a direct line of sight to the target. meaning kung naka talikod ka sa tsikot dapat di mag respond yun alarm when you press the button, like the remote of a tv.

Relaying remote entry system signals via telephone might work if the signals were sound-based, but they're not. An RKE system transmits an encrypted data stream to a receiver inside the automobile via an RF (radio frequency) signal, a signal that can't be effectively relayed via cell phone. (In any event, RKE systems and cell phones typically operate on completely different frequencies; the former in the 300 MHz range and the latter in the 800 MHz range.)

(More than a few people have inadvertently fooled themselves into believing the cell phone method of unlocking car doors actually works because they tried it and achieved the desired results — not realizing their cars were still within range of their keyless remote devices, and the signals that unlocked the doors were transmitted the usual way [i.e., through the air], not via cellular phone connections.)

It's possible this method might work with cars that use something different than standard RKE systems, but it doesn't work with the vast majority of models.

no need for mythbusters,here comes snopes.com

I believe alarms are not infrared since there is no infrared receiver on the car, even if you don't have line of sight (which is needed for infrared), you can activate/de-act the alarm. Isa pa, if its a code that is transmitted through RF, the cellphone will not relay that since iba ang modulation na ginagamit ng cell (GMSK for GSM), QPSK for 3G. Also, you can't just modulate the alarm's pulsating RF over the cell's RF signal dahil i-dedemod pa yan sa receiving side, which will filter the signal not intended for the receiver and it requires a modulator to make some signal ride over the other's.

Now you can install a device that could lock/unlock your car using your cell, that's more probable IMO.

i-try ko to mamaya as one-man Mythbuster!!

pero huwag lang dito sa work dahil ayokong magmukhang gago sa parking lot :bwahaha:

hi guys,

I tried this trick when i first read it and using a globe sim i was able to open my car. i tried duplicating the same trick with my cousins sun sim and it didnt work. maybe the network or the alarm brand has something to do with this...

[k2tingx]

i rcv the same e-mail and hurriedly tried on my fortuner...as expected, it didnt work.. i thought other brand (who claims it work) is better than my fortuner... maybe ..but not in this case..
