Key card door is known as the plastic card, similar to the credit card, that has the attached magnetic strip that is coded by the check in computer and read by the lock on the room door. The entire new key, with the different code is created for every room with every change of person. Basically, the codes from the previous use are wiped out by the computer and replaced with the new pattern that is also sent electronically to the room lock.
Apparently, the key card door is anonymous and easily changed, making it nearly impossible for the a bad person to pick up and break into the room. The only weakness of this technological version of room security is demagnetization. It is said that if the electronic key is carried too close to the magnet or the other credit card, it can lose its code.
In the game like Mad City, the key card door can be used to open prison doors. Therefore, the prisoner who has the key card door can use this one to escape or trespass through prison doors, and become the criminal. Other than that, this kind of card has no use than to let the other prisoners escape. In order to get the key card door by pickpocketing the police, the player should be a criminal or a prisoner, and then walk behind the police while holding “E”. Once the criminal or the prisoner gets the key card door, they are vulnerable death or arrest by the police officer as well as the hero.
In the world of Roblox, in order to open the door using the key card, you need a script. A site named Pastebin can be a good place to visit when it comes to the script. You can just go there and type the keyword on the Search bar without having to sign in to the site first. Then, the result will be shown after pressing Enter.
