Using a Key Programmer
Modern key fobs do more than simply function as keys. They communicate with the vehicle to turn it on, open the rear hatch, and more. To do this, they must be programmed together.
Car dealerships, your vehicle manufacturer and auto locksmiths all provide key programming services. You can also do it yourself if you have the right tools.

What is a key-programmer?
car key programming is a tool used to reprogram the transponder on the key of a truck or car key or fob. This process is required when the fob or key must be programmed. It is also often necessary in the event that an existing key or fob has been stolen or lost. The device essentially reprograms the digital signature of the chip inside the key to match the signature of the vehicle and enable it to begin.
Some vehicles have electronic immobilizer systems that stop theft by stopping the engine from starting without the correct fob or key. This is accomplished by having the car's system verify that the key or fob has the correct digital signature. The system will shut off when it isn't. This kind of system is effective in reducing theft of automobiles, and has been made compulsory for a variety of models of cars by the manufacturer.
These anti-theft systems can be controlled by a device that is placed in the vehicle’s engine or instrument panel or ignition lock. In some cases, these modules need special keys that are programmed by experts to work with the antitheft system. This is usually done by a dealer, or locksmith using computer.
It is possible to reprogramme certain keys and fobs by yourself, but it is not recommended until you are an experienced automotive technician. This is because the wrong programed key could cause the vehicle to start, run or even be destroyed. The majority of automakers have a very precise procedure to program keys.
It is recommended that if you want to offer key programming as part of your service offerings you acquire an LSID. This credential grants you access to a secure database of product information and keys and immobilizer codes via the NASTF's Secure Data Release Model. This access lets you quickly and easily program and test new key for customers. Additionally, it gives you important assistance and documentation to aid you in your day-today business operations.
How do I program an electronic key?
Key programmer devices can be used to modify the keys of your car. It will read the information from the microchip that is in your key and write new information to the chip. This will allow you to use the key and ensure that it is functioning correctly. The process of using a programer isn't easy and requires technical expertise. Therefore, before you attempt to accomplish this by yourself it is recommended to first consult an expert locksmith or locksmith for guidance.
You can also buy a key programmer online and get it professionally programmed for less than the cost to have a dealership do the work for you. However, keep in mind that not all key programmers will work with your car and you should make sure to check the product's compatibility with the model of your car prior to purchasing.
The majority of the time, you will need to have your key fob reprogrammed by a dealer. This is because the key fob will have to be reprogrammed with the specific information required by your vehicle's anti-theft system. Dealers will usually need the VIN number of your car to accomplish this, and will charge an amount. You may be able to save this cost by giving the dealer a copy of your title that you can get through the DMV in most states.
You can also reprogramme your car's keys in the event that 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 example, if you have a GM vehicle, you can insert your working key into the ignition and switch it on until the security light turns off. When the security light is out, you can remove the working key and insert the new one.
You can also buy a specialized EEPROM Key Programmer. This is a more costly but more efficient method of programming the car key. This is an advanced technology which requires that you disassemble the car and read the information from the chip inside the key. This kind of programming should only be performed by trained automotive technicians who have extensive experience in electronic repairs.
