Nissan Xtrail stolen

4 or 5G SIM modem used as a repeater ?

Does Nissan have an app allowing locking/unlocking of the vehicle ? Potential weakness giving access to the vehicle.

I use an old steering lock on my car and keep the keys in a tin which I've held next to the car to check it's not leaking signal to the keyless door receiver. Keep the keys in the microwave when I'm in the UK.

Well, you live and you learn.

One can acquire a pre-programmed box with an OBD plug. All one need do is break into a car, plug the lead into the OBD port and it will automatically disable the alarm, immobiliser and any other security and 'tell' the car that the required key is present. It takes about 20 seconds and one has to have a box specifically for that group of vehicles. No intelligence or skill is required other than knowing where to find the OPD port.

Clearly the scroats around here have go or made one programmed for an XTrail. I need to try and find the range of vehicles it will fit to know if the Murano is safe.

There are a number of solutions;

1) OBD lock - a bloody expensive metal block which fits to the OBD port and must be opened with a key.
2) An OBD socket with the wires totally rearranged into the wrong holes. Comes with an adaptor unscrambling teh wires for an ordinary OBD plug to work
3) Dummy but powered OBD socket which appears to be live but isn't. Comes with an adaptor to move the real OBD else where, typically within the glove compartment.
4) And OBD extension lead simply to more the OBD port elsewhere.

Of them all, 3) seems to me to be best combination of price and effectiveness though does involve a level of 'fitting'.

Turns out there is a 5th solution, and the one my wife has gone for.

She has had a remote fuel cut off fitted which is tied to a little tag she keeps separate from the keys but with her. One doesn't need to do, press or switch anything. But if the car gets more than about 50m from the little doohickey for more than 60 seconds it starts a routine which cuts off the fuel 60 seconds later.

Damned smart little thing, the tag is about the size of half a Wrigley's chewing gum strip, and absolutely no sign that anything is fitted at all. And since it's well up and inside the bulkhead, you'd not only have to know it was there, but also where it was, to disconnect it and reconnect the original wiring.

Makes the car impossible to nick and should one have it hijacked from you, then after you are ejected from the car you have 2 minutes to make yourself scarce before the villains get cross.

I can't find a link to it, but when/if I do I'll post it.
