Got it figured out. Its a Tracking device that was used by some Buy here pay here car lots. For when u dont pay your bill, they know where to find it to repo it.

Actually, there are too many wires for a tracker. Unless it's a CAN sniffing device, there are normally three, 12v+constant ignition sense and ground. Most immobilisers use 8, 2 x grounds, 12v+constant, ignition and 2 circuit cuts. I'l run with the tracker although it's rather small and where are the antennae?

well the way it was wired to the relay, there was only 3 wire connection into the car. and i wa told the round thing, is the antenna, i cracked it open, and its just a big cirular pattern of copper wire, soldered to the end of the 2 wires that ran into it.

Still can't make up my mind whether you're describing a tracker antenna or an RFI proximity touch key! If there was relay involved, it could have been a tracker plus immobiliser as already stated.

With antenna shielded by the body, it's probably a RFID etc.
But the why the mechanical key - is that the "key" for the RFID.
But if it's too easy so get to, it's easy to defeat.
Some car-yard enabler makes sense in case someone has duplicated the vehicle's key.
Though maybe it is for echelon targeting?

Shush don't mention Echelon! Signed paranoia Howard. Let's face it they can probably tag you from the individual EMF signal given off by your engine management!

Locally i've come across stand alone immobilisers that resemble that in his picture! ------------- COMMIT YOUR WAY TO JEHOVAH AND HE WILL ACT IN YOUR BEHALF.

Howie - that's why I hate this forum - I can't post in small font!
I don't use wireless - all my comms are hard-wired and TEMPEST protected. My windows and walls are pink & white modulated with anti-reflective coatings.
I use my vehicles anti noise "muffler" systems for the acoustics.
But don't tell anyone - that's between you & me only.
As to stand-alone immobilisers - that's presumably is an RFID system since I assume the plug-in dongle shown must be concealed - otherwise it is easily defeated. Or is there 3rd part of the system not yet shown or described?
