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.
Car dealerships, your car manufacturer and auto locksmiths all offer key programming services. You can also do it yourself if you have the right tools.
What is a key programmer?
A key programmer is a device used to change the transponder code in a car or truck fob or key. This is needed when a new fob or key has to be programmed. It is also often necessary in the event that an existing fob or key has been lost or stolen. The device reprograms the chip in the key to match the digital signature of the vehicle which allows it to begin.
Some vehicles come with electronic immobilizer systems that stop theft by stopping the engine from starting if it is not equipped with the correct fob or key. The system checks to see if the key or fob is digitally signed. If it doesn't, the system will shut down. 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.
These anti-theft systems can be controlled by a module installed in the vehicle's engine compartment, instrument panel or ignition lock. In certain instances they require keys that have been specifically created by professionals to function with the anti-theft system. This is typically done by a dealer, or locksmith using computers.
While it is possible to reprogramme some keys and fobs at home but it is not advised unless you are a highly experienced automotive technician. This is because the wrong programmed key could cause the vehicle to fail to start, run or be destroyed. The majority of auto makers have a particular procedure for programming these types of keys.
It is recommended that if you plan to offer key programming as a part of your service, you obtain an LSID. This credential grants you access to the database of immobilizer and key codes, as well as product information. This allows you to swiftly and easily program and test a new key for customers. In addition, it gives you important assistance and documentation to help you with your day-to-day business operations.
How do I program the key?
A key programmer can be used to modify the keys of your car. It reads information from the microchip in your key, and then write new information onto the chip. This will permit you to use your key and ensure that it is working properly. However the procedure of using a key programming device can be a bit difficult and requires some technical knowledge to use. Before you attempt to program the key yourself, you should consult a professional locksmith or expert for advice.
You can purchase a key programmer and have it professionally programmed online at a lower cost than the cost you would pay a dealership to complete the task for you. Be aware that not all key programmer models will work with your vehicle. You should make sure to check the compatibility of the item with your model of car prior to purchasing.
Dealers typically need to reprogramme your key fob. This is because the key fob will have to be reprogrammed with the specific information for your car's anti-theft system. A dealer will typically require the VIN number for your car to do this and they typically charge a fee to do this. You may be able to save money by giving the dealer a copy your title that you can get through the DMV in 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 it can be used to program a second key on certain vehicles. For instance, if you have an GM vehicle, you can insert your working key into the ignition and turn it on until the security light goes off. After the security light is out, you can remove the working key and insert the new one.
You can also buy an specialized EEPROM key programmer that is more expensive, but more efficient method of programming car keys. However this is a more advanced technology that requires removing the car and reading the data from the microchip inside the key. This kind of programming is best suited to professional automotive technicians who have extensive experience in electronic repair.
