Using a Key Programmer
Modern key fobs do more than just function as keys. They communicate with the vehicle to start it up, open the rear hatch, and more. To accomplish this they must be programmed to work together.
All automotive dealerships, auto manufacturers and auto locksmiths provide key programming. You can also do it yourself, if you have the right tools.
What is a key programmer?
A key programmer is used to recode the transponder on the fob or key for an automobile truck or other vehicle. This process is required when the fob or key has to be programmed. This process is often required when a key or fob is lost or stolen. The device basically reprograms the digital signature on the chip inside the key to match the signature of the vehicle, and allows it to start.
Certain vehicles come with electronic immobilizer systems that prevent theft by preventing the engine from starting if it is not equipped with the correct key or fob. The system checks whether the fob or key is digitally signed. If it doesn't it will shut down. This kind of system is effective in reducing car theft and has been made compulsory for many models of car by the manufacturer.
Most of these anti-theft systems are controlled by a module that is installed in the vehicle's engine instrument cluster, instrument cluster, or ignition lock. In some instances the modules require special keys that are programmed by experts to work with the antitheft system. This is usually done by a dealership or locksmith via the use of a computer.
While it is possible to reprogramme some fobs and keys at home, it is not recommended unless you're an experienced automotive technician. This is because a wrongly programed key could cause the vehicle to start, run or be destroyed. The majority of auto makers have a very specific procedure to program these kinds of keys.
If you want to include key programming in your service offerings It is recommended that you obtain an LSID (Locksmith Service ID). This credential allows you access to an encrypted database of product information and key and immobilizer codes through the NASTF's Secure Data Release Model. This access lets you quickly and easily program and test a new key for customers. It also provides crucial documentation and support to assist you in your day-to-day business operations.
How do I program the key?
A key programmer can be used to reprogram the keys of your car. It reads the data from the microchip that is in your key and then write new information to the chip. This will allow you to use the key, and make sure that it functions correctly. The process of using a programmer can be a bit difficult and requires technical knowledge. Therefore, before attempting to complete this task on your own you should first talk to a professional or a locksmith for directions.

It is important to know that not all key programmer products will work with your car. Before automotive key programming purchase it is important to determine if the item is compatible with your model.
The majority of the time you'll require having your key fob reprogrammed by an dealer. This is because the key fob will have to be reprogrammed with specific data for your vehicle's anti-theft system. Dealers typically require the VIN number for your car to do this, and will typically charge a fee to do it. You can save money by providing your dealer a copy of the VIN, which you are able to obtain from the DMV of most states.
For some cars you can also try to program your own key if you have another working key that works on your vehicle. This is known as master key method and it can be used to program a different key on certain vehicles. If you have an GM vehicle, for instance, insert your key into the ignition until the security light turns off. After the security light has gone out, you are able to remove the working key and replace it with the new one.
You can also buy a specialized EEPROM Key Programmer. This is a more costly but more effective method of programming a car key. This is a more advanced technology, which requires that you disassemble the car and read the data from the chip in the key. This kind of programming should only be done by certified automotive technicians who have years of experience in electronic repairs.
