Using a Key Programmer
Modern key fobs are more than simply keys; they can communicate with a vehicle to start it or open the rear hatch, and so on. To accomplish this, they need to be programmed to work with each other.
All automobile dealerships, auto makers and auto locksmiths provide key programming. You can do it yourself using the right tools.
What is car key programming ?
Key programmer is a device used to reprogram the transponder on the car or truck fob or key. This is required when a new fob or key needs to be programmed. This process is often required when a fob or a key is lost or stolen. The device essentially reprograms the digital signature of the chip inside the key to match the signature of the vehicle and allow it to begin.
Certain cars are equipped with electronic immobilizers which prevent theft by stopping the engine from being started without the proper key. This is accomplished by having the car's system check to make sure that the fob or key has the right digital signature. If it does not, the system will shut down. This kind of system is efficient in reducing car theft and was made mandatory for many models of car by the manufacturer.
These anti-theft systems can be controlled by a module installed in the vehicle's engine compartment or instrument panel, or ignition lock. In some instances the modules require special keys that have been designed by experts to function with the anti-theft system. This is usually performed by a dealership or locksmith via a computer.
While it is possible to reprogramme some keys and fobs on your own but it is not advised unless you are a highly skilled technician in the field of automotive. A wrongly programmed key can cause the vehicle to not start, or not to run or even to be destroyed. The majority of automakers have a very precise procedure for programming keys.
It is advised that if you intend to offer key programming as a part of your service, you obtain an LSID. This credential gives you access to a database of key and immobilizer codes and details about the product. With this access, you are able to program and test new keys for customers quickly and quickly. In addition, it also offers you assistance and documentation to assist you in your day-to-day business operations.
How do I program an electronic key?
A key programmer is a piece of equipment that will help you modify the keys in your car. It reads the data from the microchip inside your key, and then write new data to the chip. This will permit you to use your key and ensure that it is working effectively. The process of using a programmer can be a bit difficult and requires technical expertise. Before you attempt to make this yourself, you must consult a professional locksmith or professional for instructions.
You can also buy an online key programmer and have it professionally programmed at a much lower price than you would pay to have a dealership do the work. It is important to know that not all key programmer products are compatible with your vehicle. Before making a purchase you must see if the product is compatible with your model.
Most of the time you'll require your key fob reset by a dealer. The key fob has to be reprogrammed in order to include the specific information for the anti-theft system of your vehicle. A dealer will typically need to have the VIN number of your car to do this, and usually charge a fee for this. You can save money by giving your dealer a copy of the VIN, which you'll be able to obtain from the DMV of the majority of states.
For certain vehicles you can also try to reprogram your own key if you have another working key that works on your vehicle. This is known as the master key method, and it can be applied to some vehicles to program the secondary key. 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 goes off. After that, you can remove your working key, and then insert the new one to program it.
You can also buy an specialized EEPROM key programmer, which is a more expensive but more effective method to program a car key. This is an advanced technology which requires that you take apart the car and read the information from the chip in the key. This kind of programming is best suited to skilled automotive technicians with years of experience in electronic repair.
