D2 Immobilizer and external radio interference

greg - g,
You are not alone it seems.

Some interesting experiences here.....

Schneier on Security: Denial-of-Service Attack Against Electronic Car Locks

Thanks everyone for your comments, most interesting.

I had a close look around the area today and found nothing surprising.

It was parked outside a Dentist's at 38 Brisbane St, Launceston, Tasmania. The buildings either side are real estate offices, and across the road is a small office block. None of the buildings had scanners, or any other modern retail equipment. There are no phone towers in the immediate vicinity.

There is a lot of computer gear etc starting to come out that uses the 433 MHz (Key fob frequency?) band for communications. I'd love to find a radio scanner to see what's going on.

I guess that I was lucky this time in that I wasn't in an absolute rush, the local dealer was nearby, and I had my emergency code.

Thanks

Greg

you get around 4Bee,,:D

its interesting how people have no idea how the doors unlock.

Actually there used to be an amcal chemist in that area, but not any longer. I think it's the real estate most likely after dad had trouble in the same area.

I just found the following in the latest RACT "Motoring News" in reply to someone that had the same problem in the vicinity of the Princess Theatre. The type of vehicle wasn't mentioned.

That part of Launceston is notorious for the problem. High-voltage cables running under the road produce electrical interference on the same frequency as the remote controls for some vehicles. I doubt the interference would cause problems for pacemakers. The Launceston City Council is already aware of the problem.The most effective solution is to roll the vehicle a few feet either way - the remote should work normally again. Drivers regularly experience the same issues on Mt Wellington because of electronic signal from the transmission towers

From the Manager of RACT Roadside Assistance.

I have had this problem several times with my Disco 2004. It has occurred in suburban areas when I have parked near pole transformers and high tension wires. In the latter case, the HTW were about 100m away and while I can park facing away from the HTW without problems if I park facing its stops me from re-entering my vehicle. With the pole transformer, I need to park 30m or so away. In both cases I just enter the code and all works ok. I recommend keeping your code and the operating sequence in your wallet as, if you are like me, you can't remember the process from one occurance to another.

The RAA have erected signs at Mount Lofty Lookout carpark advising to do this due to the many call outs they have had due to the high concentration of RF interference at this high point.

The alarm system can be programmed to be disarmed with both the key and fob. Aust. vehicles are set to NO-KEY disarm.
