Car stolen? Throw away your key!

There's an interesting article in Wired magazine about how reluctant -- to put it kindly -- US insurers are to pay out on auto theft claims when the stolen car in question has a transponder-equipped key system, as our cars do. Basically the insurers have become convinced that cars so equipped are unstealable (unless towed) and as a result, if your car is actually stolen, shows no signs of having been towed, and you have all your keys, they are likely to accuse you of fraud and deny your claim. I was particularly fascinated by the discussion of back doors in most of these cars, which give you a way to start the car even with a dead key. The notion of a back door isn't that surprising, just how it may be implemented. In the case of the author's Honda Civic, a series of handbrake pulls before twisting the key allows the car to start even with the transponder disabled. Bonus points to anyone who finds out the Volvo back door!

I'm not aware of anyone here who has had the misfortune of having their S40/V50 nicked, but I guess the moral is to approach your insurer carefully if you ever do.

Does anyone know the backdoor to our S40/V50s?

My battery is dying already and I haven't been able to find a back door in the manual. What can we do to disable the alarm in case the battery runs out and we're forced to use the aluminium key?

Re: (VolvoINSIDE)

I bought my V50 from a dealership owned by Jim Pattison. Anyone familiar with the BC area, will know the name. Few dealerships he doesn't own, not to mention billboards, publishing, etc.

Anyway, if my V50 is stolen, Jimmy P will give me a cheque for $4000. Well, so long as it is not recovered. That's how confident they are in the Volvo security.

Even if someone knew, I don't think it would be smart to post it in a public forum...

Just get a new battery.

Re: (VolvoINSIDE)

The battery enables the fob's lock/unlock buttons. The key itself is a passive RFID device and you'll be able to enter your car with the aluminum blade, and start your car without any battery in the remote at all.

Try it! But be prepared, because the siren will go off when you enter the car after unlocking without the remote. It will stop when you insert the ignition key.

I doubt there's a back door. But, anything's possible. There are many ways to steal a car.

I tend to believe that there's a BD here. Considering that in software business it's a matter of good practices to always create a backdoor and the fact that our cars are pretty much computers with wheels - there should be one. The other thing is that you won't find the description in the owner's manual, or it'll become a thief manual.

You are correct Tom - you don't really need to steal the car f you want to get a possession of it, it damages the hardware. Quite enough to take a gun and politely ask the owner to vacate it on some relatively remote parking lot. I'm sure everyone will comply. I will, for sure. This way is getting implemented in Toronto nowadays.
Another way - on a cold winter morning many drivers first warm the car up while sipping their morning coffee inside. Most cars remain unlocked. Do you homework and pickup whichever one you like.

I would go with "common practices" but in cases of security I wouldn't consider it "good practices". I would be more inclined to consider this a horrible idea especially in this day and age with how quickly information is shared via the web. If Volvo saw fit to implement a "backdoor" as an end around to their expensive secure ignition system then that system really isn't going to be secure for too long. They might as well just dump the system and go back to a standard steel key. If there is a backdoor the info will get out at some point and make our $300+ keys little better then the old steel keys. Of course with how often I have had to "reboot" my car to get some "feature" to work properly again, a backdoor wouldn't surprise me.

But the point of the article is that such backdoors do exist (along with many manufacturers giving locksmiths key blanks that can be used to create RFID key clones when the original key is lost), which means such cars are quite a bit more stealable than insurers, and many others perhaps, want to believe they are. Not saying that Volvo has done either one, but if they haven't, they may be the exception.

I caught that, as they do in many forms of software. That was why I stated

I was just clarifying that it may be a common practice but not a good practice in a case involving security.
