Using a Key Programmer
Modern key fobs aren't simply keys; they can communicate with vehicles to start it, open the rear hatch, and so on. To do this, they need to be programmed.
All automobile dealerships, auto makers, and auto locksmiths offer key programming. But you can do it yourself if you have the right tools.
What is a key programmer?
Key programmer is a device that allows you to reprogram the transponder on a car or truck fob or key. This is required when a new fob or key needs to be programmed. It is also necessary when an existing fob or key has been lost or stolen. The device essentially reprograms the digital signature of the chip inside the key to match the signature of the vehicle, and allows it to start.
Certain vehicles come with electronic immobilizers that stop theft by preventing the engine from starting without the proper key. This is done by having the system examine to ensure that the fob or key has the right digital signature. The system will shut off if it doesn't. This kind of system is efficient in reducing theft of automobiles, and has been made compulsory for a variety of models of cars by the manufacturer.
These systems can be controlled by a module installed in the vehicle's engine, instrument panel, or ignition lock. In certain instances they require keys that are specifically programmed by an expert to work with the anti-theft system. This is typically performed by a dealership or locksmith through computers.
While it is possible to reprogramme some fobs and keys by yourself however, it is not recommended unless you're a highly skilled technician in the field of automotive. The reason is that a poorly programmed key could cause the vehicle to fail to run, not start or be destroyed. The majority of auto makers have a specific procedure to program keys.
It is recommended that if you plan to offer key programming as a part of your service you get an LSID. This credential grants you access to a database of immobilizer and key codes, as well as product information. Having this access allows you to program and test new keys for customers quickly and easily. In addition, 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 is a piece of equipment that allows you to modify the keys in your car. It reads the information from the microchip in your key and write new data to the chip. This will allow you to use your key and will ensure that it works properly. The process of using a programmer can be a bit complicated and requires technical expertise. So, before you try to do this yourself you should first talk to a professional or a locksmith for guidance.
You can also purchase an electronic key programer and have it professionally programmed at a lower cost than what you would pay an auto dealer to do the work for you. However, keep in mind that not all key programmers will be compatible with your car and you should make sure to check the compatibility of the product with your vehicle's model before purchasing.
Dealers usually have 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 of your vehicle to perform this, and typically charge a fee to do it. You may be able to save this cost by giving the dealer a copy your title which is available through the DMV in all states.
For some cars you may also be able to reprogram your own key if you have another working key that is compatible with your vehicle. This is known as master key method, and can be used to program a different key for certain vehicles. For example, if you are driving a GM vehicle, insert your working key into the ignition and turn it on until the security light goes off. Once that happens then you can remove the working key and insert the new one to program it.
car key programming can also purchase a specialized EEPROM key programmer which is a more expensive but more effective method of programming car keys. This is a more advanced technology, which requires you to take apart the car and read the data from the chip inside the key. This kind of programming should only be carried out by certified automotive technicians who have extensive experience in electronic repairs.
What are the best choices for the most experienced programmers?
