Using a Key Programmer
Modern key fobs do more than just act as keys. They communicate with the vehicle to get it started, open the rear hatch, and more. To do so they must be programmed to work with each other.
Car dealerships, your car manufacturer, and auto locksmiths can all offer key programming services. You can do it yourself with the right tools.
What is a key programmer?
A key programmer is used to reprogram the transponder on the fob or key of a car or truck, or any another vehicle. This process is required when the fob or key needs to be programmed. It is also often necessary in the event that an existing fob or key is lost or stolen. The device basically reprograms digital signature of the chip inside the key to match that of the vehicle and allow it to begin.
Certain vehicles come with electronic immobilizers that prevent theft by stopping the engine from starting without the right key. This is accomplished by having the system check to make sure that the fob or key has the right digital signature. The system will turn off when it isn't. This type of system has been proved to be effective in reducing the incidence of theft and was made mandatory for various models of vehicles by the manufacturer.
The anti-theft system can be controlled by a device that is placed in the vehicle's engine compartment, instrument panel, or ignition lock. In some instances, these modules need special keys that have been designed by experts to work with the antitheft system. This is usually done by a dealer or locksmith with a computer.
It is possible to reprogram certain keys and fobs yourself, but it is not recommended until you're an experienced technician for automotive. The wrongly programmed key could cause the vehicle not to begin, stop running or even to be destroyed. The majority of automakers have a very precise procedure for programming keys.
If you're looking to include key programming in your service offerings It is recommended that you acquire an LSID (Locksmith Service ID).

It also provides crucial documentation and support that can aid you in your daily business operations.
How do I program an electronic key?
Key programmer devices can be used to modify the keys of your car. It will read information from the microchip in the key, and add new information to the chip. This will permit you to use the key and will ensure it works properly. The process of using a programmer can be a bit difficult and requires technical expertise. So, before you try to complete this task by yourself, you should first consult an expert locksmith or locksmith for directions.

Most of the time, you will require having your key fob reset by a dealer. This is because the key fob will have to be reprogrammed with the specific information for your car's anti-theft system. Dealers will usually need to have the VIN number of your vehicle in order to do this and they typically charge a fee to do it. You may be able to save this cost by giving the dealer a copy of your title, which you can obtain through the DMV in all states.
For some cars you may also be able to program your own key if you already have a working key that is compatible 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 instance, if you are driving a GM vehicle, you can insert your working key into the ignition and turn it on until the security light goes off. Once this happens you can take out your working key, and then insert the new one to program it.
You can also buy an specialized EEPROM Key Programmer. This is a more costly but more effective method of programming a car key. This is the most advanced technology available, which requires you to remove the car from its frame and read the information from the chip in the key. This kind of programming should only be done by professional automotive technicians with extensive experience in electronic repairs.
