Using a Key Programmer
Modern key fobs do more than just act as keys. They communicate with the vehicle to start it up and open the rear hatch, and more. To accomplish this, they need to be programmed to work together.
Car dealerships, your car manufacturer, and auto locksmiths can all offer key programming services. But you can also do it yourself if you have the right equipment.
What is a key programmer?
A key programmer is a device used to reprogram the transponder on the key of a truck or car key or fob. This is needed when the fob or key must be programmed. It's also common when an existing fob or key has been lost or stolen. The device essentially reprograms the digital signature on the chip inside the key to match the signature of the vehicle and allow it to start.
Certain vehicles come with electronic immobilizers that protect against theft by stopping the engine from starting without the correct fob or key. The system checks to see whether the fob or key is digitally signed. The system will turn off if it doesn't. This type of system has been found to be effective in reducing the incidence of theft and was made mandatory for many models of cars 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 certain instances, these modules require special keys that are specifically programmed by professionals to work with the anti-theft system. This is typically performed by a dealer or locksmith who uses computer.
While it is possible to reprogramme some keys and fobs by yourself, it is not recommended unless you're an experienced automotive technician. A wrongly programmed key can cause the vehicle to not begin, stop running or even break. The majority of auto makers have a very specific procedure for programming these types of keys.
If you want to include key programming into your service offerings it is recommended you obtain an LSID (Locksmith Service ID). This credential allows you access to a secure database of product information as well as keys and immobilizer codes via the NASTF's Secure Data Release Model. This allows you to quickly and easily program and test a new keys for customers. It also provides essential documentation and support to help you with your daily business operations.
How do I program an electronic key?
Key programmer devices can be used to reprogram the keys of your car. It will read information from the microchip on the key, and add new information to the chip. This will allow you use the key and ensure that it works properly. The process of using a programmer can be a bit complicated and requires technical expertise.

Be aware that not all key programmers are compatible with your vehicle and you must ensure the compatibility of the item with your vehicle's model before purchasing.
In most cases you'll require your key fob reprogrammed by a dealer. The key fob needs to be reprogrammed to include the specific information for your car's anti-theft system. A dealer will typically require the VIN number of your vehicle in order to do this, and will typically charge a fee for this. You could be able save this cost by giving the dealer a copy of your title that you can get through the DMV in all states.
For some cars you may also be able to program your own key if you have a second working key that works on your vehicle. This method is called the master key method and it can be applied to certain vehicles in order to program an additional key. If you have an GM car, for example, insert your key into the ignition until the security light turns off. Once that happens you can take out 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 more expensive, but more efficient method to program the car key. This is a more advanced technology, which requires that you remove the car from its frame and read the information from the chip inside the key. This kind of programming should only be performed by certified automotive technicians who have vast experience in electronic repairs.
