Lost key... is there an app that can find it?
 

I remember reading in the user manual that mobile phones can interfere with the key being recognized by the car if they are too close to each other.

Is there an app that can tell me if I am near the key?

Also any idea on the cost of replacement for a key like this below?

I am sry to say that this might be the stupidest question/comment yet on this site that i read, wtf do you think is inside the key? Bluetooth mini computer wih wifi access?

But dont feel bad i lost the key with the plate that has the numbers on it within 2 days off owning the car i think thats gotta be a record, stupid jacket with shitty pockets...

Sry on sencond thought it might be possible somehow but way more work then its worth, you would need the app to recognize the code thats broadcasted by your other key and then detect it by walking around all over where you think you might have lost it, but i doubt he key broadcast very far so you might be in visual range of the key b4 the app would even see it, i am thinking like 1-2meters.

@Alabang BRZ I hear what you're saying; you'd need some way to detect the radio from the key fob, only thing is the key fob doesn't broadcast unless the button is pressed.

Question was asked on another forum "How can I detect the signal from a key fob?" http://www.nerdkits.com/forum/thread/2133/

And the short answer is a 315 mHz +/- 2.5 mHz detector, etc.

Are you sure it doesnt broadcast? So when you walk up to the door pull the handle the car broadcasts to find a fob and then then fob broadcast back?

Yeah I need some way to detect the key fob. I know the fob constantly transmits a (low power) signal because by just by walking beside the car door the interior lights turns on without me touching the door handle.

Is there an android or iPhone app that can read that frequency? I just need it to detect a signal source. Don't mind searching one room/car for it rather than 6 cars and 6 rooms.

Note: light turns on during the evening. Daytime it doesn't happen. Where I live is now 321pm.

Found out from dealership key fob cost about 250+ half hour programming and guy wasnt sure if it was just the fob or came with the metal key

contact Apple. They'll be able to tell you if "there's an app for it" or not.

I was about to post that until I saw your post. Good idea but lets see how far it gets.. It can be used as an easy tracking system for creepers also.

This looks incredibly cool, it's too bad it's iPhone only at the moment.

OP, it's not necessarily a matter of having an app to do it, the phone would need to be able to detect/use the same frequencies as the car/fob. I have no idea what the car uses. If it's RFID and you have a newer phone that has an RFID scanner or a NFC chip, you may be onto something.



There's a bunch of other similar products out there that work on Android or iOS.
