Using a Key Programmer

Modern key fobs do more than just function as keys. They communicate with the vehicle to turn it on and open the rear hatch, and more. To accomplish this they must be programmed to work in conjunction.

Car dealerships, your vehicle manufacturer, and auto locksmiths can all provide key programming services. You can also do it yourself if you have the right tools.

What is a key programmer?

A key programmer is a device used to recode the transponder in the fob or key of the vehicle or truck, or any another vehicle. This is required when a new key or fob needs to be programmed. It is also often necessary when an existing fob or key is lost or stolen. The device basically reprograms digital signature on the chip inside the key to match the signature of the vehicle, and allows it to start.

Certain vehicles come with electronic immobilizers that prevent theft by preventing the engine from running without the right key. The system checks to see whether the fob or key is digitally signed. The system will turn off in the event that it doesn't. This kind of system has been proven to be effective in reducing the incidence of theft and is now required for many models of cars by the manufacturer.

These anti-theft systems can be controlled by a module installed in the vehicle’s engine, instrument panel, or ignition lock. In some instances the modules require specific keys that are programmed by professionals to function with the anti-theft system. This is typically carried out by a dealer or locksmith through computers.

It is possible to reprogram certain keys and fobs yourself, but it is not recommended until you are an experienced technician in the field. This is because a wrongly programmed key could cause the vehicle to fail to start, run or even be destroyed. The majority of auto makers have a very precise procedure to program these keys.

It is recommended that if you want to offer key programming as part of your service you acquire an LSID. This credential allows you access to an encrypted database of product information as well as key and immobilizer codes through the NASTF's Secure Data Release Model. This access lets you quickly and easily program car keys and test a new key for customers. In addition, it offers you assistance and documentation to aid you in your day-today business operations.

How do I program my key?

A key programmer can be used to reprogram the keys in your car. It reads the information from the microchip in your key, and then write new information to the chip. This will allow you to use the key, and make sure that it works properly. However, the procedure of using a key programer can be somewhat complicated and requires some technical knowledge to utilize. So, before you try to accomplish this by yourself, you should first consult a professional or a locksmith for directions.

You can also buy a key programmer online and get it professionally programmed at less than what you would pay to have a dealership complete the work. You should be aware that not all key programming products are compatible with your vehicle. Before you purchase it is important 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 have to be reprogrammed with specific data for your vehicle's anti-theft system. Dealers will usually need the VIN number of your vehicle to do this, and they will charge fees. You may be able to save this cost by giving the dealer a copy of your title that you can get through the DMV in the majority of states.

For certain vehicles you can also try to reprogram your own key if you have a second working key that works on your vehicle. This is called master key method, and it can be used to program car keys a different key on certain vehicles. For instance, if are driving a GM vehicle, simply insert your working key into the ignition and turn it on until the security light goes off. After the security light is out, you can 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 of programming a car key. This is the most advanced technology available, which requires that you remove the car from its frame and read the data from the chip inside the key. This kind of programming should only be carried out by certified automotive technicians who have extensive experience in electronic repairs.

What are the top key programmer options?

There are a number of options when it comes to key programmers. Some key programmers are designed to serve a single purpose, such as generating new keys. Others have diagnostic and service functions to make them a multi-purpose tool in a mechanic's shop. XTool is one such company that makes a range of key programming devices that have been well-received by their customers.

One of their most well-known models is the XTOOL Inplus IP616, which has been rated as one of the best in its category. It offers a simple, user-friendly interface and extremely clear instructions that guide users through the procedure of programming a new key. There are two ways to do this: by vehicle or via type.
