Using a Key Programmer

Modern key fobs go beyond simply keys; they can communicate with vehicles to start it, open the rear hatch, and much more. To do so they must be programmed to work with each other.

Car dealerships, your automobile manufacturer, and auto locksmiths can all offer key programming services. You can do it yourself using the right equipment.

What is a key programer?

A key programmer is used to reprogram the transponder in the fob or key for an automobile, truck or other vehicle. This process is necessary when the new key or fob has to be programmed. It's also common in cases where an existing fob or key is lost or stolen. The device reprograms the chip within the key to match the digital signature of the vehicle and allows it to start.

Some vehicles are equipped with electronic immobilizers that stop theft by stopping the engine from starting without the right key. The system checks if the key or fob is digitally signed. The system will turn off if it doesn't. This type of system has been proven to be effective in reducing automotive theft and is now required for various models of vehicles by the manufacturer.

These systems can be controlled by a device that is placed in the vehicle’s engine instrument panel, instrument panel, or ignition lock. In some cases the modules require special keys that have been designed by experts to function with the anti-theft system. This is usually performed by a dealer or locksmith with computers.

Although it is possible to reprogramme car key some keys and fobs at home, it is not recommended unless you're a highly experienced automotive technician. This is because the wrong programmed key can cause the vehicle to start, run, or even be completely destroyed. Most auto manufacturers have a specific method for programming these types of keys.

If you want to include key programming into your service offerings it is recommended you acquire an LSID (Locksmith Service ID). This credential gives you access to a secure database of product information and key and immobilizer codes through the NASTF's Secure Data Release Model. This lets you quickly and easily program and test a new key for customers. In addition, it offers you support and documentation that can help you with your day-to-day business operations.

How do I program an electronic key?

A key programmer can be used to reprogram the keys in your car. It reads information from the microchip inside your key, and write new information onto the chip. This will allow you to use the key and ensure that it works correctly. The process of using a programmer can be a bit difficult and requires technical expertise. Before you attempt to program the key yourself, you must consult a professional locksmith or professional for guidance.

You can purchase an electronic key programer and have it professionally programmed at a lower cost than the cost you would pay an auto dealer to do the job for you. It is important to know that not all key programming products will work with your car. Before you purchase, you should check to determine if the item is compatible with your vehicle.

In most cases you'll require having your key fob reprogrammed by an dealer. The key fob needs to be reprogrammed in order to include the specific information for the anti-theft system of your vehicle. Dealers will usually need to have the VIN number of your car to do this, and will typically charge a fee to do it. You can save money by providing your dealer a copy of the VIN, which you are able to obtain from the DMV of the majority of states.

For certain vehicles, you can also try to program your own key if you already have a working key that works on your vehicle. This method is called the master key method and it is applicable to certain vehicles to program the secondary key. If you own a GM car, for example you can insert your key into the ignition until the security light turns off. When the security light is out, you can take off the working key and then insert the new one.

You can also buy a specialized EEPROM key programmer, which is a more expensive, but more efficient way to program car keys. This is the most advanced technology available, 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 professional automotive technicians who have years of experience in electronic repair.
