Using a Key Programmer
Modern key fobs do more than simply function as keys. They communicate with the vehicle to start it up, open the rear hatch, and more. To do this, they have to be programmed together.
All car dealerships, auto manufacturers and auto locksmiths provide key programming. You can do it yourself using the right tools.
What is a key programer?
A key programmer is used to reprogram the transponder on a key or fob for a car truck or another vehicle. This is needed when a new fob or key has to be programmed. It's also common in the event that an existing key or fob has been stolen or lost. The device basically reprograms the digital signature of the chip inside the key to match the signature of the vehicle, and allows it to begin.
Certain vehicles come with electronic immobilizer systems that stop theft by preventing the engine from running without the correct fob or key. This is accomplished by having the car's security system check to make sure that the key or fob has the right digital signature. The system will shut off when it isn't. This kind of system has been found to be effective in reducing automobile theft and was made mandatory for many models of cars by the manufacturer.
Most of these anti-theft systems are controlled by a module that is installed in the engine compartment, instrument cluster, 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 done by a dealer, or locksmith using a computer.
It is possible to reprogram certain fobs and keys yourself but it isn't recommended until you're an experienced automotive technician. A wrongly programmed key can cause the vehicle not to start, fail to run or even break. Most auto manufacturers have a specific method for programming these types of keys.
It is recommended that if you plan to provide key programming as part of your service offering, you obtain an LSID. This credential allows you access to the database of immobilizer and key codes along with details about the product. This allows you to quickly and easily program and test new keys for customers. It also provides important documentation and support that will assist you in your everyday business operations.
How do I program an electronic key?
Key programmer is a piece of equipment that can help you change the key codes in your car. It reads information from the microchip inside your key, and then write new information to the chip. This will allow you to use your key and will ensure that it is working correctly. However, the procedure of using a key programming device is a bit complicated and requires some technical know-how to use. Before you attempt to make this yourself, you must seek the advice of a professional locksmith professional for guidance.
You can also purchase an electronic key programer and have it professionally programmed online at a cost that is lower than what you would pay an auto dealer to do the work for you. You should be aware that not all key programming products are compatible with your vehicle. Before purchasing a product, you should check to make sure that the product is compatible with your model.
Dealers will usually need to reprogramme your key fob. This is because the key fob will need to be programmed with the specific data for your vehicle's anti-theft system. A dealer will typically need to have the VIN number of your car to do this and they typically charge a fee for it. You can save money by giving your dealer a copy, which you will be capable of obtaining from the DMV of the majority of states.
programming car key can also reprogramme your car's keys if you already have a functioning key. This method is called the master key method and it can be applied to some vehicles to program an additional key. If you own a GM vehicle, for instance, insert your key into the ignition until the security light turns off. Once this happens, 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 efficient way to program the car key. However, this is a much more advanced technology that requires removing the car and reading the information from the microchip inside the key. This type of programming is best for professionals in the field of automotive mechanics who have years of experience in electronic repair.
