Lotus Elise vulnerable to keyless remote hack

Was reading yet another article on car hacking today and was surprised to see that the researcher tested it on an Elise of all cars. I wonder if he's a member here...

I have partially bypassed my immobilizer but left the starter circuit such that the fob is needed. Seeing these makes me lean towards getting rid of it entirely even more

Already discussed a bit here:

Any kind of one-way remote without a clock in both ends is obviously vulnerable from a theoretical standpoint, so this isn't really news. Opening garage doors has been a DIY "getting started with Software Defined Radio" project for years now.

If someone commercializes a cheap device like this on the black market I suppose it could become an issue with joyriding, but honestly, it requires enough premeditation to use that I don't think people will do it on a whim, an Elise isn't lucrative to steal (you can't exactly sell it to the chop shop) and if someone has you targeted specifically, you have way bigger problems than key fob replay attacks.

Well, yes, but does this keyless hack extend the range at which the keyless entry can be effective (with the hack of course)? Probably not. The distance is limited by the antenna.

What's the lesson here? If you see someone next to your Lotus doing something weird, they are probably trying to hack your car. If they are more than 5 feet away, they will die of frustration first.

Living in Wisconsin with a Lotus sucks eight months of the year except for one thing... I've never locked my car. I don't ever keep anything valuable inside, and I figure anyone who really wants to get in will, so why force them to destroy the car in the process?...

I also calculate that your average two-bit thief is baffled by a manual transmission and/or a Lotus itself, while a professional won't be stopped by much of anything. I also don't think that a Lotus is a chop shop target for a number of reasons.

Fortunately a hackable key code for me is irrelevant.

Exactly the 1st thing I thought.

Criminal would have to be in the car with me....

...or at least next to me.

The poor range is actually a boon for the attacker, because the compromise revolves around the attacker receiving the key fob's signal while the car doesn't. Since the attacker could make a better receive antenna than the one in the Lotus out of a coat hanger, they're at the advantage.
