Front door - plastic or aluminum

Nevertheless, you cannot compare a car and a door. The rolling code cannot be copied; instead, the whole thing is cracked using a jammer. Although I wouldn't really call it "cracking" since the code is not copied. However, a jammer cannot be used on the door because when leaving, no radio signal is sent like with the car. Instead, the door automatically locks when the lock is closed, not only upon receiving a radio signal. When coming in, a radio signal is indeed sent to open, but you still cannot get in if a jammer is nearby, as the door does not open. So how is that supposed to work?

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

Yes, I looked it up now because I was interested. An article about a hacker who built a device that intercepts 2 radio signals and could use one of them himself. However, this assumes that the homeowner presses the remote control twice if the door does not open the first time, because of the mandatory jammer to be used. Let's say he actually does that without thinking anything of it. But then he would be INSIDE THE HOUSE when the hacker intercepts his signal, which becomes invalid after a short time. What use is that to the burglar, does he want to rob the house while the owner is at home? As I said, the house lock is not locked by radio signal like a car. So never when leaving, and only then would it make sense.

That already helps - he just goes in at night. Don’t fool yourself - there is no perfect security. And the system can also make the much-maligned front door attractive.

As stated, the code becomes invalid after a short time. At least with modern, newer systems. Perfect security definitely doesn’t exist, but the effort required to overcome the rolling code, if it is even realistically possible with a front door, is considerably higher than simply breaking a window if the owner is actually not at home. Or stealing the front door key from their handbag. However, I am not a security fanatic. We have 2 entrances, the great security door and a normal balcony door upstairs as the exit door to the ground-level conservatory. When I am home alone, I often go away for half an hour into the forest and leave everything wide open. So not just closed, but really wide open. That also happens from time to time when I go shopping. Of course, I find the security of the front door good, but it was mainly about the convenience of opening. And the radio key version is definitely not less secure than an ordinary front door that you open with a key, that is enough for me.

The remote key is not comparable to a car remote key, which is relatively easy to crack by intercepting and copying the radio signal. However, this is not possible with the rolling code, as no signal can be used twice

Car keys have had rolling keys for a long time. There aren’t that many chip manufacturers worldwide supplying the system components.

By the way, the keyword is "RollingJam" or "Anatomy of the RollJam Wireless Car Hack". No code is used twice here. The "first" code never even reaches the lock. When the 2nd code is sent, the "first" is cleverly sent by the RollingJam. So as long as no one else comes in the meantime, the "attacker" has the 2nd code. And you don't lock with radio anyway.

The fingerprint scanner as well, it doesn’t scan the surface. Absolutely not comparable to these pseudo fingerprint scanners on phones.

Apple’s is already "quite" good. But there aren’t that many fingerprint scanner producers. It’s just a question of the right materials. However, I don’t really see this as an attack vector yet; because obtaining the right ingredients (a good print) is difficult.

The problem with electronic burglary vectors is that you can’t see at all that a break-in occurred. So, if someone in your personal/close environment is suspicious about it, e.g. a neighbor or an ex stalking someone, possibilities open up :cool _O
