Keys
Almost all modern cars require some kind of transponder key or fob in order to operate, ensuring security and protection against theft. The keys are programmed by a locksmith or an authorized dealer to work with your car's system and the specific model. It's expensive to replace them if they're lost, so it's best to have spares available. You can find key fobs that can be replaced in online stores and numerous brick-and-mortar auto shops. How do you ensure that the one you have bought is authentic? Are you able to tell whether it has been programmed for a different vehicle or if it can be reprogrammed for yours?
If you want to program a new key, the first step is to ensure that your car is on and running. Insert the key you'd like to reprogramme into the ignition, but do not turn it. You have only a few seconds left before the system will reset all commands and leaves the programming mode. It is crucial to move quickly and don't be patient between each step. Shut off the engine to avoid this. Switch the key from "on" to "off" to test the system. The door locks should cycle, and you will hear a chime signalling that the process has been successful.
Certain cars with more modern technology have rolling key system, which stops thieves from using a stolen vehicle's key to open it. This technology is still vulnerable to a technique known as replay attacks which allows thieves to record the signal of the key fob of the car and reproduce it later to unlock the car. To prevent this, manufacturers have introduced an additional security feature known as the CAN bus protocol to thwart attacks on hacking.
Certain manufacturers have a unique encryption on their keys, which can't be decoded with a simple program. You should only attempt this method if your previous experiences are with electronics. It is recommended to read your car's owner manual or search for the manufacturer on the internet, since the steps will differ depending on the car model.
Transponder chips
Car keys that feature transponder chips require a special reconfiguration to work. Any hardware store can make you an entirely new car key, but the real challenge is in making it work with your car. A reprogrammed key will need to be matched with the specific identification number of the vehicle, or it won't start the engine.
Transponder chips are a standard feature of modern automobiles and are designed to stop car theft. The chip is a microcircuit which emits a radio frequency signal when the key is inserted into the ignition. The car is able to detect the signal, and starts the engine only if the signal matches the original one that was programmed into the vehicle. The car also shuts down if a frequency is invalid. This makes it much harder for car thieves with no experience to hot wire a vehicle and start it.
The chip and the key are linked by an electronic circuit board that contains an induction coil. When the key is put in the ignition the magnetic field is created around the transponder. This creates a signal that gets taken up by the coil, which sends it to the key's identification number. The key's identification code is transmitted back to the car and the engine is started when the identification number matches.
There are a few different methods to program a transponder key however, all require an instrument that is specifically designed for the purpose. These tools can be bought online or from most automotive locksmiths. These tools are not inexpensive, but they are vital for programming the chip in your car.
You may also use a reprogrammable transponder key that was previously programmed for a different vehicle. In this scenario, make sure that the key hasn't been damaged or the transponder is not altered in any way. To accomplish this, you can use scanners or a computer equipped with a USB port to identify the chip and establish its identity.
Reprogramming a transponder is a simple procedure, but requires special software. It also requires an scanner tool. If you're just beginning it is recommended to seek help from an auto locksmith. Avoid buying used keys as they could already be programmed and will not work with your vehicle.
