Reprogramming Car Keys
Car keys with transponders are believed to make vehicles more secure and less likely to be duplicated by thieves. A key may have to be reprogrammed in the event that it is damaged or lost.
You can change the programming of your key fobs at home, but you need to be aware of the correct procedure. For the best results you must have the following items:

The majority of modern vehicles require a transponder key to operate. This gives security and anti-theft protection. These keys are programmed by a locksmith or authorized dealer to function with your car's system and specific model. It is expensive to replace them if they're lost, so it's better to have spares available. You can purchase key fobs to replace them in online stores, as well as numerous brick-and-mortar auto shops. How can you know that the key you purchased is genuine? Can you tell if it has been programmed to work with another vehicle or if it is able to be reprogrammed to fit your vehicle?
To program a new car key, you must first ensure that your car is running. Insert the key you wish to program into the ignition without turning it. You have only a few seconds before the system resets all commands and then exits the programming mode. It is important that you move quickly and do not wait between each step. Turn off the engine to prevent this. You can check the car's system by turning the key to the "on" position, then back to the "off" position. There should be a chime indicating that the process was successful. The door locks will cycle.
Some newer cars use a rolling key technology that prevents thieves from using stolen cars' key to start it. This feature is still vulnerable to a technique called replay attack. It allows thieves to record and reproduce the signal from the key fob of the vehicle to open the car. To stop this, manufacturers introduced security features known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.
Some manufacturers use a special encryption on their keys that cannot be decoded using a simple program. These kinds of cars require to be programmed by a professional. Therefore, you should only attempt this process only if you've worked with electronics. It is recommended to read the owner's manual for your car or look up the manufacturer on the internet, since these steps vary by vehicle type.
Transponder chips
Car keys with transponder chips require a special reprogramming to work. While any hardware store can cut keys for you, the main challenge is making it function in conjunction with your particular car. The key must be programmed to match the exact identification number on your vehicle, or else it won't be able to start.
Transponder chips are a common feature in modern cars and are designed to stop car theft. The chip is a small microcircuit that emits a radio frequency signal when the ignition key is put in. 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 will also shut down if the frequency is not valid. This makes it difficult for thieves with no experience to wire a vehicle hot and then turn it on.
The chip and the key are connected via the circuit board which includes an induction coil. When the key is put in the ignition the magnetic field is generated around the transponder. This produces a signal which is amplified by the coil which then transmits it to key's identification number. The key's identification number is sent back to the car and the engine is started when the identification number is in line with.
There are a variety of ways to program a transponder, but each requires the use of a specific tool. These tools can be purchased through the internet or from many automotive locksmiths. They are not cheap, but they are vital for programming the chip in your vehicle.
You could also use a resettable key that was programmed for a different vehicle. In this instance, you must ensure that the key hasn't been damaged or that the transponder isn't altered in any way. To do this, you'll need a scanner or a computer with an USB port to scan the chip and determine its identity.
Reprogramming an transponder is a simple process, but requires specialized software. It also requires a scanner tool. It's best to ask an auto locksmith for assistance in case you're not an expert. Don't buy used keys since they may already be programmed and won't work with your vehicle.
