Using a Key Programmer
Modern key fobs do more than just function as keys. They communicate with the vehicle to turn it on, open the rear hatch and more. To accomplish this, they need to be programmed.
Car dealerships, your vehicle manufacturer, and auto locksmiths can all provide key programming services. You can do it yourself with the right tools.
What is a key programer?
A key programmer is a tool used to change the transponder code in the key of a truck or car key or fob. This is required when a new fob or key needs to be programmed. This is usually required when a fob or a key is lost or stolen. The device basically reprograms digital signature on the chip inside the key to match that of the vehicle and allow it to begin.
Some vehicles have electronic immobilizers that protect against theft by preventing the engine from starting if it is not equipped with the correct key or fob. This is done by having the car's security system check to make sure that the key or fob has the correct digital signature. If it doesn't then the system will shut down. This kind of system is efficient in reducing automobile 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 or instrument cluster or ignition lock. In certain instances, these modules require special keys that are designed by a professional to function with the anti-theft system. This is usually done by a dealership or locksmith via a computer.
While it is possible to reprogramme some fobs and keys by yourself, it is not recommended unless you're a highly skilled automotive technician. The reason is that a poorly programmed key can cause the vehicle to fail to start, run or be destroyed. The majority of automakers have a very precise procedure for programming these keys.
It is recommended that if you want to provide key programming as part of your service you get an LSID. This credential grants you access to an encrypted database of information about the product and key and immobilizer codes through the NASTF's Secure Data Release Model. Having this access allows you to create and test new keys for customers quickly and easily. It also provides essential documentation and support that can help you with your daily business operations.
How do I program my key?
Key programmer is an equipment that allows you to modify the keys in your car. It reads data from the microchip on your key, and write new information to the chip. This will allow you to use the key, and ensure that it functions correctly. The process of using a programer can be a bit complicated and requires technical expertise. Before you attempt to program the key yourself, you must consult a professional locksmith or expert for advice.
You can also purchase a key programmer and get it professionally programmed online at a lower cost than what you would have to pay a dealership to complete the task for you. Be program keys for cars that not all key programming products will work with your specific vehicle. Before purchasing a product it is important to determine if the item is compatible with the model you have.
The majority of the time, you will require having your key fob reset by a dealer. This is because the key fob will need to be programmed with the specific data for your vehicle's anti-theft system. Dealers typically require the VIN number of your vehicle to accomplish this, and they charge fees. You can save money by providing your dealer a copy of the VIN, which you will be able to obtain from the DMV of all states.
For certain vehicles you may also be able to program your own key if you have a second working key that works with your car. This is referred to as master key method and can be used to program a different key for certain vehicles. If you have an GM car, for example, insert your key into the ignition until the security light turns off. Once this happens then you can remove your working key and then insert the new one to program it.
You can also purchase an exclusive EEPROM Key Programmer. This is a more costly but more efficient method of programming the car key. However, this is a much more advanced technology that requires dismantling the car and reading the information from the microchip inside the key. This type of programming is ideal for professional automotive technicians who have years of experience in electronic repair.
