What Door Key Cannot Be Copied? A Comprehensive Guide to Key Duplication

Transponder keys are a type of key that use microchips to transmit a low-level RFID signal from the key to the receiver. If the receiver recognizes the serial number, the door is open. These keys are specifically designed with unique serial numbers, making it nearly impossible to copy them. Transponder keys are used in cars and cannot be copied because an internal computer chip sends an encrypted code.

These chips are programmed to prevent duplication and the codes cannot be deciphered with any existing instrument. They use resistors and have a built-in electrical modification. If the value of the current entered into the memory with a given engine wrench does not match that of the installed resistor, the car will not start. The VAT code can be duplicated to some extent, but it cannot be replicated if the original one is broken.

There are no rules or laws that prevent duplicating a password with the text “Do not duplicate”. While hardware store chains may refuse to duplicate these keys, locksmiths can often provide a duplicate key. An expert locksmith can also provide you with the information, locks, and keys needed to protect your business property from unwanted intruders. This is because only locksmiths are supposed to be able to make copies of these keys, and they will have to do their best to prevent this from happening and, therefore, make your home much safer.

Not only will the professional locksmith duplicate most keys, but he can also ensure that you know which keys can be easily duplicated and which ones could provide a better form of security.

Once you've made a duplicate from a restricted key, you should be able to duplicate the keys as many times as possible. This is done primarily for security reasons to protect homeowners or businesses that share key access with different people. High security locks require an access card and cannot be duplicated. Unfortunately, there's nothing you can do that makes your key truly unique or difficult for others to duplicate.

Landlords and property managers began spreading the message of “don't duplicate the key” in an attempt to control safety violations committed by laid-off employees, former tenants, construction workers, and others who were left with a key. There are several types of keys and it's useful to know which ones a locksmith will duplicate for you.
