Reprogramming Car Keys
Car keys with transponders are believed to make vehicles safer and are less likely to be duplicated by thieves. However, keys may require reprogramming when it becomes damaged or lost.
You can change the key fobs you own but you must be aware of the proper procedure. To get the best results, you'll need the following items:
Keys
The majority of modern vehicles require a transponder keys to operate. This is a security feature and anti-theft protection. The keys are programmed by a locksmith or an authorized dealer to function with your car's system and the specific model. It is expensive to replace them if they are lost, so it's a good idea to keep extras on hand. You can also find replacement keys fobs at various online stores and in many brick-and-mortar auto shops. How can you ensure that the one you purchased is authentic? Can you tell if the unit has been programmed to work with another vehicle, or if it can be programmed again?
To program a new car key you must first ensure that your vehicle is operating. Insert the key you want to program into the ignition, but do not turn it. There are only a few seconds left before the system resets all commands and then exits the programming mode. Therefore, it is essential to move fast and not pause between steps. Shut off the engine to prevent this. Change 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.
Some newer vehicles use rolling keys to keep thieves from using stolen keys to start the vehicle. The feature is still vulnerable to a technique called replay attack. It allows thieves to record and then reproduce the signal from the vehicle key fob to unlock the car. To counter this, manufacturers have introduced an additional security feature known as the CAN bus protocol to thwart attacks on hacking.
Certain manufacturers employ a specific encryption on their keys that can't be decoded with an easy program. You should only attempt this method if your previous experience is in electronics. It is a good idea to refer to your car's owner manual or search for the manufacturer online, as the steps will differ depending on the car model.
Transponder chips
Car keys with transponder chips need special programming to function. Any hardware store can make you a new car key, however the real challenge lies in making it work with your car. The key must be programmed to match the exact identification code on your car, otherwise it won't start.
Transponder chips, used to prevent car theft, are a common feature of modern cars. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is placed. The car then scans for the signal and then starts the engine if it matches the original frequency that was programmed into the vehicle. The vehicle is also programmed to stop when it detects an incompatible frequency. This makes it much more difficult for car thieves with no experience to connect a vehicle with hot wires and start it.
A circuit board that has an induction coil that connects the chip to the key. When the key is placed in the ignition, it creates a magnetic field around the transponder. This creates a signal which is taken up by the coil before being sent to the key's identification number. The ID number of the key is transmitted back to the vehicle, and if it matches the engine will begin to run.
There are many methods to program a key transponder, however each requires a special tool. You can buy these tools online or at most locksmiths in the automotive industry. These tools aren't cheap but are essential to program your car's chip.
You could also use a unreprogrammable key that was programmed for a different vehicle. In this scenario, you'll need to make sure that the key has not been damaged or that the transponder has been altered in any way. The chip can be read with a scanner, or a computer equipped with an USB connector.
The process of reprogramming an transponder's key is simple, however it requires an expertly designed software and scan tool. It's best to ask an auto locksmith for assistance for those who are new to the process. You should also avoid buying second-hand keys as they're likely to be programmed and will not be compatible with your car.
