Using a Key Programmer
Modern key fobs aren't just keys. They communicate with a vehicle to start it or open the rear hatch, and so on. To do so they must be programmed to work in conjunction.
All automobile dealerships, auto makers and auto locksmiths can provide key programming. However, you can also do it yourself, if you have the proper equipment.
What is a key developer?
A key programmer is used to recode the transponder on the fob or key for the vehicle truck or other vehicle. This process is required when the fob or key needs to be programmed. This process is often required when a fob or key is stolen or lost. The device reprograms the chip within the key to match the digital signature of the vehicle which allows it to begin.
Some vehicles are equipped with electronic immobilizers which prevent theft by preventing the engine from being started without the correct key. This is accomplished by having the system verify that the key or fob has the correct digital signature. The system will shut down when it isn't. This type of system has been proven to be effective in reducing the incidence of theft and was made mandatory for a variety of models of cars by the manufacturer.
The anti-theft system can be controlled by a device that is placed in the vehicle's engine compartment or instrument panel, or ignition lock. In some cases the modules require special keys that have been designed by experts to work with the antitheft system. This is usually done by a dealership or locksmith using computers.
While it is possible to reprogramme some keys and fobs at home but it is not advised unless you're a highly experienced automotive technician. This is because a wrongly programmed key could cause the vehicle to run, not start or be destroyed. The majority of auto manufacturers have a specific procedure for programming keys.
It is recommended that if you plan to offer key programming as a part of your service offerings, you obtain an LSID. This credential allows you access to an inventory of immobilizer and key codes and information about the product. Having automotive key programming allows you to program and test new keys for customers quickly and easily. It also provides essential documentation and support that can aid you in your everyday business operations.
How do I program the key?
A key programmer can be used to reprogram the keys in your car. It reads the data from the microchip that is in your key and then write new data to the chip. This will allow you to use the key and will ensure it functions effectively. The process of using a programmer can be a bit complicated and requires technical knowledge. Before you attempt to do this yourself, seek out a locksmith professional for instructions.
You can also buy a key programmer online and have it professionally programmed for an affordable cost than what you would pay to have a dealership complete the work for you. Be aware that not all key programming products will work with your car. Before purchasing a product it is important to make sure that the product is compatible with your vehicle.
In most cases, you will need to have your key fob reprogrammed by an dealer. This is because the key fob will have to be reprogrammed with the specific data for your vehicle's anti-theft system. Dealers will usually need the VIN number of your vehicle to do this, and they charge fees. You can save money by giving your dealer a copy, which you will be in a position to get from the DMV of the majority of states.
You can also reprogram your car's keys if you already have a working key. This is referred to as master key method, and it can be used to program a second key for certain vehicles. If you own an GM vehicle, for instance you can insert your key into the ignition until the security light goes out. When the security light is out, you can remove the working key and replace it with the new one.
You can also buy a specially designed EEPROM key programmer, which is a more expensive, but more efficient method of programming a car key. However it is a more advanced technology that requires removing the car and reading the data from the microchip in the key. This kind of programming is best for professionals in the field of automotive mechanics who have years of experience in electronic repair.
