Simple Scenario:-

* You may have shut your boot & locked your car keys in

* You may be a long way from home

* But you have your mobile on you

* You call a relative at home who locates your spare key with remote attached

* Ask the relative to activate the "Unlock" button on your spare remote (next to their phone) whilst your phone is near the car

* Your car unlocks

Sinister Scenario:-

* You might have a valuable car

* You can be parked anywhere

* Two thieves...

* #1 is near your side and sees your key with remote attached

* #2 goes outside into the carpark with his mobile to wait for car lights to blink

* #1 with his mobile, calls #2 and activates "Unlock" on your remote (near the phone)

* Your car unlocks

P.S. If your battery in the remote is getting weak, press the "Unlock" button whilst placing it next to your neck > you get a couple more goes at it, before battery exchange.

Have you ever dried it before?

I did with my alarm system in the 33 when i locked my keys in the car.

Called up home (35-40 mins away) and got them to do this exact thing. Note that both batteries were fresh, as i had changed both within the week.

All i got was a buzzing through the phone. Didnt unlock. So i gues it depends on how the remotes work.

Scenario 2.. BS.

I have found the Arcing your arm to your neck does seem to work however. It also works for a distance thing. Like if think youve forgotten to lock the car and have already walked away.

Mobile phone's use licensed radio frequency spectrum to transmit audio information (sound) encoded into data, and car alarm keyfobs use unlicensed RF spectrum to transmit lock and unlock codes.

So,

- they use different RF frequencies

- they dont understand each other's data

So - it sounds like bollocks to me, but i'm not an expert.

Of course, people without security engineering backgrounds regularly design security systems. These systems are easily cracked because the designers assume that just because they can design a system that they themselves cannot break that it is therefore secure. WEP encryption from Wifi networks is an example of this.

Hey,

You're talking about transmitting the radio-toggle-lock-code over a voice call on a mobile network, right?

Typical car remotes operate at 300-400MHz - way outside the "voice range" (say 0-2.4KHz) that could be successfully transmitted over a mobile phone.

Even if the signal were in the voice range, the compression that operates on mobile phone calls would probably prevent successful transmission.

Cheers,

SW

It works with some of the commodore remotes, my father locked the keys in his hsv, he called my mother who was some 20km away, she pushed the remote and held it up to the phone and it worked. Confussed the shit out of me because I was always told it doesn't work.

My car remote only disables the immobilizer for my car.

The doors uses good old keys, so if I locked my keys in, its either crow bar time or call RAC...

After locking my keys in my car before, I made it a habit to always use the keys to lock my doors so that won't happy again.

Interesting find! :thumbsup:

I will give it a go when I get a chance.

chin idea works - been using that for 20 yrs.

It's been theorised that the skull creates a resonant cavity at the frequency used (433MHz) - and that empty cavities work best.

Oops!! Hi Chris :)

As for holding up a remote to your mobile phone... LOL doesn't quite cover it. FKN LOL!!! gets close. You're dreaming.

    • Its also worth mentioning that 30 years after it left the factory and god knows how many missed oil changes since, there is every possibility that one or more lifters are ticking because they are sticky/gummed up. To resolve that you need to pull the cams then pull each lifter, disassemble, clean, reassemble, soak in oil and re-install, and they should come up good as new.
    • What air filter are you running? Is it a panel filter in the stock air box, or a pod filter? Is the air filter the type that is oiled?   If you unplug the IACV, what rpm does the engine idle at?
    • Reading through the engine service manual their advice is do a cylinder balance test. Unplug one injector at a time and see if the idle drops a consistent RPM. You can also do this using a Consult cable which is easier. They also call for unplugging the power transistor, then with the engine off and the fuel rail unhooked from the manifold verifying that you have good fuel flow (even injection, no dripping/leaks, etc) when you twist the CAS by hand. Also verify the spark by pulling the spark plugs and allowing the plugs to ground and turning the CAS by hand. I would also start doing the sensor checks and idle valve checks in service manual. Make sure the MAF tests reasonably, the intake air regulator is sane, etc. You may have to get new spark plugs.
    • This sounds very old of me, however since buying the Tiguan shit box, my view on shit boxes have changed.
    • I've looked up the parts number (41011AL501). It's around $700 OEM. Usually our Infiniti G35 here in Canada have interchangeable parts with my Stagea but the parts number are not the same. I have looked around and it seems the JDM 2005 V35 Skyline (which is the same as our G35) has the same caliper but I cannot confirm. And I can't find a repair kit. The inner brake pads drags on the rotor, seems to be rusty piston. Thanks for the info by the way
