Using a Key Programmer
Modern key fobs go beyond simply keys; they can communicate with a vehicle to start it, open the rear hatch, and more. To do this, they have to be programmed.
Car dealerships, your vehicle manufacturer and auto locksmiths all provide key programming services. You can do it yourself with the right tools.
What is a key developer?
A key programmer is a device that allows you to change the transponder code in the car or truck key or fob. This is needed when the fob or key must be programmed. It's also common in the event that an existing fob or key is stolen or lost. The device basically reprograms the digital signature on the chip inside the key to match that of the vehicle and enable it to begin.
Certain vehicles come with electronic immobilizers that prevent theft by stopping the engine from running without the right key. This is accomplished by having the car's system check to make sure that the key or fob has the right digital signature. 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 is now required for many models of cars by the manufacturer.
Most of these anti-theft systems are controlled by a module installed in the vehicle's engine, instrument cluster, or ignition lock. In some cases these systems require specific keys that have been programmed by professionals to function with the antitheft system. This is typically performed by a dealership or locksmith via a computer.
It is possible to reprogramme certain keys and fobs yourself, but it is not recommended until you're an experienced automotive technician. A key that is not properly programmed could cause the vehicle not to start, fail to run or even to be destroyed. Most auto manufacturers have a very specific procedure to program these kinds of keys.
It is recommended that if you want to offer key programming as part of your service offering you get an LSID. This credential grants you access to a database of immobilizer and key codes, as well as information about the product. This access lets you quickly and easily program and test new keys for customers. In addition, it also gives you important assistance and documentation to help you with your day-to-day business operations.
How do I program a key?
Key programmer is a piece equipment that allows you to reprogram your car's keys. It reads data from the microchip on your key, and write new information onto the chip. This will allow you to use the key and ensure that it is functioning correctly. The process of using a programmer can be a bit difficult and requires technical knowledge. Before you attempt to program the key yourself, you should seek the advice of a professional locksmith expert for advice.
You can purchase a key programmer and have it professionally programmed online at a cost that is lower than the cost you would pay an auto dealer to do the job for you. However, keep in programming car key that not all key programmer models are compatible with your vehicle and you must ensure the compatibility of the product with your model of car before making a purchase.
In most cases you'll need to have your key fob reprogrammed by an dealer. The key fob needs to be reprogrammed so that it can include the information specific to your car's anti-theft system. Dealers typically require the VIN number of the car to accomplish this, and they charge an amount. You can save money by providing your dealer a copy of the VIN, which you'll be able to obtain from the DMV of most states.
For certain cars you may also be able to reprogram your own key if you have a second working key that works with your vehicle. This is known as the master key method and it can be applied to some vehicles in order to program the secondary key. For example, if you are driving an GM vehicle, insert your working key into the ignition and switch it on until the security light turns off. When the security light goes out, you are able to remove the working key and insert the new one.
You can also buy an specialized EEPROM key programmer, which is a more expensive, but more efficient method to program the car key. However, this is a much more advanced technology that requires dismantling the car and reading the information from the microchip within the key. This kind of programming is best for professional automotive technicians who have years of experience in electronic repair.
