In the past, cars relied upon simple metal keys to unlock their doors and start their engines. Keys like these were easy to duplicate of and were easily lost or stolen. Most vehicles now include key fobs with a transponder inside. These chips link the key to the car's security system, making sure that only the authorized person can open and start the car.

This process uses a scan tool to read the unique identifier in the new key or remote and then transmit the information to the vehicle's system.

This feature is vital because it will help you save time and money as you don't need to wait for the correct part from a different country.
Transponder Chips
Many modern cars come with transponder chips that communicate with the car's computer system. The chip emits a digital code each time the key is inserted in the ignition barrel. This unique code identifies the key as a genuine key. This technology adds a security layer of security to modern cars and lowers the risk of theft. To benefit from the added security features on cars, it is necessary to have the key properly cut and programmed. This service can be provided by a certified auto locksmith or dealer.
The first step to changing the transponder's programming is to make sure that the key is equipped with a circuit board or transponder that is of the right type. The key must be compatible with the on-board computer of the vehicle, and also have a keyring that is correctly placed around the ignition barrel.
This type of reprogramming typically done using the transponder cloning machine which is able to copy a specific circuit board or transponder. This equipment is available from important blank manufacturers as well as reprogramming specialists. The cloning device must be able to read the data transmitted by each transponder that is being cloned. Some cloning devices are upgradeable and can be used to copy the most recent transponders that are released.
A locksmith who provides transponder key programming will have the tools needed to ensure that the new key is cut properly. They can supply the replacement key using an authentic transponder or a generic key that works on the vehicle. They can also help the customer in obtaining the right blank key.

The transponder chip makes it virtually impossible to start a vehicle without the use of a key. A professional locksmith will install the transponder chip and program it into the car to allow the car to start.
PIN codes
PIN codes can be utilized in various ways to shield private data from cyber and physical attacks. PIN codes are a sequence of numbers, generally four or six digits, that is used to authenticate transactions using banking systems and other card-based devices, governments with citizens, companies with employees, and computers with users, among others.
Many automakers require keys to transmit the VIN number of the vehicle along with the transponder code. These additional security measures often require specific key programming procedures which are not available to independent mechanics unless they have access to a dealer only tool like Autel's Immobilizer scanner tool IM608 or Launch Tech’s XProg3 scanner.
When programming a new key, it's important to choose an encryption method that is simple to remember, however, it is difficult for anyone else to figure out. This is why most experts recommend using an assortment of letters and numbers. It is also a good idea to avoid using personal information like birth dates, phone numbers or social security numbers as these are easily deciphered by hackers. Make sure your PIN has at least six numbers for the most secure protection. This makes it harder for hackers to crack your PIN. However there are methods that can help you overcome this.
Data Transfer
Data transfer results in a pair of persistent copies one at the origin and one at the destination. If the destination doesn't need an existing copy of the data, this may not be a problem - however, it could be a problem in the event that the data is evolving or needs to be updated constantly. Idealy, one copy of data should be discarded when it is no longer needed.
In certain situations the transfer of data may involve a third party - such as an IT department or cloud service provider. In this case, it's important to understand who is responsible for overseeing the process of transfer and the data being transferred. This will help avoid any issues that could arise from unauthorized access or corruption of the data.
Key programming is an excellent tool for auto repair shops, however there are limitations that technicians need to be aware of. First, Putrino said that a shop will need to procure an ID for locksmiths (LSID). This credential grants technicians access to the vehicle's immobilizer as well as PIN codes by using the National Automotive Service Task Force's Secure Data Release Model.
Other considerations include ensuring the shop has the appropriate scanners needed to manage the process. car key programming will need to be capable of extracting the PIN code directly from the modules, as well as permitting technicians to program a new keys. Many OEMs also require that the key transmit more than its ID code. VW, Chrysler, and other companies require that the key transmits the VIN number unique to the vehicle. These additional transmissions are programmed using a a special key program tool.
Key programming is a difficult procedure that not many technicians offer, but it can be a lucrative business for those who can. For shops looking to get started, Putrino recommended considering a professional key programming tool, such as the AutoPro Pad from XTool USA. This tool is able to perform a variety of functions including EEPROM read/write and BMW CAS3/2 Key Learning, remote learning for Mercedes Benz, and more.
