Keys copied7/14/2023 Only then can you start your car using the new transponder key.īesides, the transponder keys are the standard of car key manufacturing. Therefore, you have to first reprogram the immobilizer system and sync it with your car’s RFID. But that system will prevent you from starting your car using a replica key. You can make a replica of a transponder key from hardware or locksmith. Otherwise, the immobilizer or anti-theft system will not allow you to start the car. Moreover, the car will only start when both the codes match. This system is responsible for verifying the code of the RFID chip in the key and the code programmed in the car’s sensor. When you insert the key in the ignition, your car recognizes the code, which is programmed into the car’s immobilizer system. The purpose of that chip is to mitigate the risk of car theft. Transponder KeyĪ transponder key, also known as the chipped key, has an RFID chip installed in the head. That’s the first type of car key we’ll discuss. Therefore, the car key manufacturers decided to introduce RFID (Radio Frequency Identification) technology in car keys. Since the locks were finite in number, and the mechanical combination was simple to break, car theft became common. The purpose of this struggle is to keep the security of the cars intact.įrom 1950 to 1980, when only mechanical keys were standard, it was easy for thieves to try their luck on any car with a random key. The automobile industry kept on changing the car key standard with varying technology. So, if you want to make a copy of your car key, first, you have to know what type of key you have and what you want as a replica. The car’s security sensors will detect that a replica of the original key is trying to mechanically unlock the door. Even if a person having negative intentions copies your car key, they won’t be able to get inside your car. The key fobs were introduced to enhance automobile security. That data inside the key fob is encrypted, and thus, there is so far no machine that can decrypt that data. Even though it has the mechanical key attached, you can’t access your car’s security sensors without a key fob. Moreover, it works electronically and stores data about your car. A key fob is a handheld remote device attached to a key.
