The Basics of Key Programming
It's not as easy as it may seem. Most people will go to a locksmith or dealer to do this.
With the right equipment in place, brick and mortar parts departments can handle key programming. This article will provide a few of the fundamental concepts of key coding so that you can start.
Modern Vehicles
Modern vehicles utilize a variety of electronic devices to communicate with the vehicle's internal systems. These systems include key fobs and remote start systems. Vehicle key programming has become important to the automotive industry as it helps ensure that these devices function correctly.
In the past, automobiles relied on simple keys made of steel to unlock doors and start engines. These keys were easy to make copies of and were easily stolen or lost. Today, the majority of vehicles are equipped with key fobs with a transponder chip inside. These chips are used to connect the key to the car's system to ensure that only the authorized person can open and begin the vehicle. This is important as it makes it more difficult for thieves to steal a car and allows owners to replace a lost or damaged key easily.
Many modern vehicles come with security features which prevent them from starting until the correct key is in place. These systems are great to protect your car from theft. However they require you to learn how to program your keys correctly.
If you're a locksmith or auto technician having the ability to program keys is a must. You may require this service in three different situations:
In the beginning, you may be able to assist someone who is having difficulty getting their car to start. This is usually the result of the remote control or key isn't programmed correctly. This issue can be fixed by using a key programing tool that is compatible with the model of your vehicle.
You might also need to perform this procedure if you're adding an extra key to your vehicle. Onboard key programming is available on most modern vehicles. This process utilizes a scan tool to read the unique identification in the new remote or key and transmit this information to the vehicle's system.
Some key programming tools are bidirectional, allowing data to be transferred between two vehicles. This is especially useful in situations where an element needs to be replaced or flashed. This is important as it can save time and money by cutting down on the time it takes to wait for the right part to arrive from overseas.
Transponder Chips
A lot of modern cars are equipped with transponder chips that communicate with the car's computer system. The chip emits a digital code each time the key is inserted into the ignition barrel. This unique code identifies the key as a valid key. This technology adds an extra layer of security for modern cars and helps to reduce the chance of theft. However, in order to take advantage of this security enhancement the key must be cut correctly and programmed. This service is offered by a qualified auto locksmith or a dealer for cars.
The first step in changing the transponder's programming is to ensure that the blank key has a circuit board or transponder of the proper type. The key should also be compatible with the vehicle's onboard computer and include a key ring that is positioned correctly around the ignition barrel.
This type of reprogramming typically done using a transponder cloning machine, which can copy a specific circuit board or transponder. Certain key blank manufacturers as well as some reprogramming experts offer this equipment. The cloning device must be able to read the data that is being transmitted by each transponder which are being copied. Some cloning machines are upgradeable and can be used to copy the latest transponders.
A locksmith who offers transponder key programming will have the tools to ensure that the new key is cut precisely. They can also provide a replacement key with an authentic transponder or generic key that will work on the vehicle. In addition, they could assist customers in purchasing the correct blank key.
Transponder keys are a very vital element of the security and safety features in modern automobiles. They are designed to stop hot-wiring, which is a common method used by thieves to take vehicles. The transponder chip makes it virtually impossible to start a vehicle without a key. A professional locksmith will install the transponder chip, and then program it into the car to allow the car to be started.
PIN Codes
PIN codes can be utilized in a variety of ways to protect private data from physical and cyber attacks. A PIN code is typically an eight-digit or six-digit sequence of numbers that is used to verify transactions between banks and other devices for credit card as well as between citizens and governments employees, businesses and government officials and computers as well as users and employees.
A lot of automakers now require keys to transmit the VIN number of the vehicle, and also the transponder code. These additional security measures require special key programming procedures that are usually not accessible to independent mechanics unless they have access a dealer-only tool such as Autel's Immobilizer Scan Tool (IM608) or Launch Tech's X-Prog3 scanner for immobilizers.
When programming a new key, it is important to select an encryption method that is simple for you to remember but difficult for someone else to figure out. Most experts recommend a combination of letters and numbers. It is also recommended to not use personal information such as birth dates, phone numbers or social security numbers as these can be easily guessed by hackers. Make sure your PIN has at least six digits for the best protection. This makes it harder for hackers to brute-force guess your PIN. However, there are technologies which can overcome this.
Data Transfer
Data transfer creates two permanent copies of the data -- one at the source, and one at the destination. This may not be an issue when the destination does not require an exact copy of the data. However, automotive key programming could be an issue if the data changes or requires to be constantly updated. The ideal is to have a backup copy of the data should be discarded when it's no longer needed.
In certain situations, a data transfer may involve a third party such as an IT department or a cloud service provider. In this scenario, it is important to determine who is responsible for managing the transfer process as well as the data being transferred. This can help prevent any issues that might result from access that is not authorized or loss of data.
Key programming is a useful tool for auto repair shops to use, but there are certain limitations that technicians need to be aware of. Putrino explained that the first step is to obtain a locksmith ID. This credential permits technicians to access the vehicle's PIN codes and immobilizer codes using the Secure Data Release Model of the National Automotive Service Task Force.
Also, ensure that the shop has scanners that can handle the process. The scanners must be capable of extracting the PIN code directly from the modules as well as allowing technicians to program new key. In addition, a lot of OEMs require that the key transmit more than its ID code. VW, Chrysler, and other manufacturers demand that the key transmits the unique VIN number of the vehicle. These additional transmissions can be programmed by using a special key programming tool.
A lot of technicians don't offer key programming however those who do can make a lot of money. For shops seeking to start, Putrino recommended considering a professional key programming tool like the XTool USA AutoPro Pad. This tool is able to perform a variety of functions including EEPROM read/write, BMW CAS3/2 Key learning, remote learning for Mercedes Benz, and more.
