Using a Key Programmer
Modern key fobs do more than simply function as keys. They communicate with the vehicle to get it started and open the rear hatch, and more. To do this, they need to be programmed together.
Car dealerships, your car manufacturer and auto locksmiths all provide key programming services. You can do it yourself using the right tools.
What is a key programmer?
Key programmer is a device used to reprogram the transponder on a car or truck fob or key. This process is required when a new fob or key must be programmed. It's also common in cases where an existing fob or key is lost or stolen. The device basically reprograms digital signature of the chip inside the key to match the signature of the vehicle and enable it to begin.
Certain cars are equipped with electronic immobilizers that stop theft by stopping the engine from being started without the proper key. The system checks if the key or fob is digitally signed. If it does not, the system will shut down. This type of system has been found to be effective in reducing automotive theft and has been made mandatory for many models of cars by the manufacturer.
The majority of these anti-theft systems are controlled by a module installed in the vehicle's engine instrument cluster, instrument cluster, or ignition lock. In some cases, these modules require special keys that are designed by an expert to function with the anti-theft system. This is typically performed by a dealer or locksmith with a computer.
It is possible to reprogramme certain keys and fobs yourself but it isn't recommended until you are an experienced technician in the field. The reason is that a poorly programmed key can cause the vehicle to fail to start, run, or even be completely destroyed. The majority of auto manufacturers have a specific procedure to program these keys.
If you are planning to include key programming in your service offerings, it is recommended that you acquire an LSID (Locksmith Service ID). This credential allows you access to a database of immobilizer and key codes along with information about the product. With this access, you are able to create and test new keys for customers quickly and effortlessly. It also provides crucial documentation and support that will help you with your day-to-day business operations.
How do I program my key?
A key programmer is a piece equipment that can help you reprogram your car's keys. It reads the data from the microchip that is in your key and write new data to the chip. This will allow you to use the key and will ensure that it works correctly.

Before you attempt to make this yourself, consult a professional locksmith or expert for advice.

Be aware that not all key programmers are compatible with your vehicle and you must confirm the compatibility of the item with your model of car before purchasing.
In most cases you'll require your key fob reprogrammed by an dealer. This is because the key fob needs to be reprogrammed with specific information for your car's anti-theft system. Dealers typically require the VIN number of your car to accomplish this, and they charge an amount. You can save money by giving your dealer a copy of the VIN, which you are able to obtain from the DMV of most states.
You can also change the programming of your key on some cars if you already have a working key. This is called master key method, and can be used to program a second key on certain vehicles. For instance, if you are driving an GM vehicle, insert your working key into the ignition and switch it on until the security light goes off. Once that happens, you can remove your working key and then insert the new one to program it.
You can also buy a specially designed EEPROM key programmer which is a costlier but more effective way to program the car key. However, this is a much more advanced technology that requires removing the car and reading the data from the microchip within the key. This type of programming should only be done by professional automotive technicians with vast experience in electronic repairs.
