ᐅ Front Door – PVC or Aluminum

Still, you can’t really compare a car and a door. The rolling code can’t be copied; instead, the whole system is hacked using a jammer. Although I wouldn’t really call that “hacking,” since the code itself isn’t copied. With the door, however, a jammer can’t be used because when you leave, no radio signal is transmitted like with a car. Instead, the door locks automatically when you pull it shut, not after receiving any radio signal. When entering, a radio signal is sent to unlock the door, but you won’t get in if there’s a jammer nearby, since the door won’t open. So how is that supposed to work?

The breach itself is intercepted and the algorithm is copied. Every system is vulnerable.

Yes, I looked into this because I was curious. There was an article about a hacker who built a device that intercepts two radio signals and then uses one of them himself. However, this requires the homeowner to press the remote control button twice if the door doesn’t open the first time due to a mandatory jammer being used. Let’s say the homeowner actually does this without thinking much of it. Then the homeowner would still BE INSIDE the house when the hacker intercepts the signal, which becomes invalid after a short time. What good is that to a burglar who wants to break in while the owner is at home?
As I said, the house lock is not operated by radio signal like a car. So it is never locked with the remote when leaving, and only then would it even make sense.

That already helps – it just goes inside at night.

Don’t fool yourself – there is no perfect security.

And the system can also make the often criticized front door more appealing.

As mentioned, the code becomes invalid after a short time. At least, that's how it works with modern, newer systems. Perfect security is certainly impossible, but the effort required to bypass the rolling code—if it is even realistically possible for a front door—is significantly higher than simply breaking a window when the owner is not home, or stealing the front door key from their handbag.
That said, I am not a security fanatic.
We have two entrances: a high-security door and, upstairs, a regular balcony door leading out to the ground-level conservatory. When I’m home alone, I often leave for half an hour to go for a walk in the woods and leave everything wide open—not just closed, but fully wide open. This also happens occasionally when I go shopping.
Of course, I appreciate the security of the front door, but my main concern was convenience when opening it. And the wireless key system is definitely not less secure than a standard front door that you open with a key, which is sufficient for me.

The wireless key is not comparable to a car remote key, which is relatively easy to hack by intercepting and copying the radio signal. This is not possible with rolling codes, as no signal is used twice.

Car keys have used rolling codes for a long time. There are also not many chip manufacturers worldwide that supply the system components.

By the way, the keyword is "RollingJam" or "Anatomy of the RollJam Wireless Car Hack." No code is ever used twice. The "first" code never actually reaches the lock. When the second code is sent, the "first" is cleverly sent by the RollingJam device. So, as long as no one comes in between, the "attacker" ends up with the second code. And you don’t usually lock with a remote control anyway.

The fingerprint scanner doesn’t scan the surface, either. It is absolutely not comparable to the primitive fingerprint scanners on smartphones.

Apple’s is already "quite" good. But there aren’t many fingerprint scanner manufacturers. It’s just a matter of using the right materials. However, I don’t really see it as an attack vector yet, because obtaining a good fingerprint copy is difficult.

The problem with electronic burglary vectors is that you can’t tell if a break-in has occurred at all. So if someone close or personal—like a neighbor or an ex stalking someone—is suspicious, certain opportunities arise :cool _O
