After market proximity key?

I recently saw an interesting episode of Top Gear highlighting a Mercedes car. I was wondering if there was an after market proximity key, such as for the Mercedes that would allow me entry into the truck and also start it with a push button? The Nissan Rogue has the feature and I'd love to integrate it.

So....

I take that as a NO?

Nothing like good old fashion turning a key.

The one thing that scares me about this is that the standards for RFID-based systems are somewhat lacking when it comes to encryption. The automotive manufacturers basically took off-the-shelf technology and adapted it to fir their purpose, without regard for potential security issues later.

To me, the bottom line on this is that RFID has been proven to be hackable. Using readily-available components, I can build a scanner that will let me pick up your RFID info fairly easily. I can then clone that chip, and use it as a means of stealing your car.

Here's a scenario: A guy with a backpack and an RFID scanner could walk past the restaurant's Valet Parking stand, scan the IDs of all the so-equipped keys, then simply start broadcasting the cloned IDs as he walks through the Valet Parking lot. Nicholas Cage never had it so easy.

Also: If you have one of the newer RFID-equipped passports? Be very careful where you leave it. There are even companies selling specialized wallets to block their signals now. When mine is up for renewal, I'll have to buy one.

There's a very good discussion here: http://www.schneier.com/blog/archives/2005/10/rfid_car_keys.html
