Bob is interested in home automation, but he's concerned with security. Can it run amuck? Leo says that it's such a new thing, we don't really know all the downsides yet. Keyless entry is the challenge, especially with a car. A car uses keyless entry with the keyfob signal by proximity. You can actually buy a booster to send it out further. But that's a security flaw. Anything with a computer can have flaws and bugs in programming. So it is possible and Bob's right to pay attention to it. But we're in the very early days. Just remember that a lock is an illusion, not a security feature. It's a statement to the honest to stay away. but it doesn't stop a criminal, does it?
