Yet another reason to NOT buy a new car. At least with a physical key, the thief was slowed down a bit. Electronic keys are too easily spoofed if you have access to the OBD port.

I had NO idea that thieves could use the OBD Port to clone a key until I read this article. The article mentions ODB Port locks, so I searched for that and, bingo, found a bunch of them.

Here's one:

It clamps around the OBD port making it very difficult for anyone to access the OBD port. It will take a lot of time to be able to break this off or drill it out. The main body is full aluminum but the top plate is made of hardened steel to make it harder to drill out. It also has an anodized coating to weatherproof it.

Just don't lose your OBD Port lock key.
