Lost car keys

Dec 16, 2018 Last reply: 7 years ago 14 Replies

Can't get a replacement due to an unresolved issue with the V5. And no, they don't fit Adam's van. Is there such a thing as a key finding device that can help track them down - obviously it's not possible to attach a transmitting tile to them before locating them. I'm hoping there might be something that can detect the RFID chip in the key. It's for a Vauxhall.



cheers NT


In short, I would have thought "not a chance". The range of RIFD chip reading is low, so unless your key was within range of a reader AND you knew the code of the chip AND that the chip code was registered with some sort of key finding service, you're never gonna track a key that way.

There ought to be a way of pinging it and tracing the reply signal, I'd have thought. Have you searched on YT? There's always someone that's had any given problem before.

I'd say unlikely given how that chip is powered and the very limited range it requires.

Yes there is a means of doing that, a non linear junction detector. But if you have to ask about the price you cannot afford one.

If you can't negotiate / bluff your way through the 'highly secure' dealer key / transponder supply chain then It might be easier to buy a matched set of ECU/immobiliser/ignition key from a breakers.

Unless you are an eastern European car thief possibly? Brian

It doesn't matter what code a scanner returns, just that something is returned on the right frequency. Anyone know what the range of these things is? It's not a remote unlocker, it just oks the ignition. It takes a coin cell.

They key situation got sorted, so I'll get an rf trackable tile for future times.

Coin cells are usually for the remote unlocking (or a torch). The RFID is an unpowered passive device.

You wouldn't want an immobiliser dependant on a device that could go flat.

snipped-for-privacy@gmail.com presented the following explanation :

The RF ID chip is a grain of rice size and derives it power from the device which interogates it, a coil around the ignition lock. Rang is just a few inches. The coin cell is only for the remote un/locking system.

snipped-for-privacy@gmail.com explained on 16/12/2018 :

The only solution will be with the V5 and a trip to a Vauxhall dealership..

Having just fitted a new case to one of mine, it doesn't. The battery only powers the remote control side. That chip isn't connected to any power source. Bit like a credit card.

why would anyone specialise in stealing Eastern European cars?

Well there was an advert in a hairdressers near me for an Eastern European hairdresser.

In Shepherds Bush Road there used to be a "Ladies Colonial Hairdresser".
