Using a Key Programmer
Modern key fobs are more than just keys. They communicate with a vehicle to start it or open the rear hatch, and so on. To accomplish this, they have to be programmed.
Car dealerships, your vehicle manufacturer, and auto locksmiths can provide key programming services. You can do it yourself with the right tools.
What is a key programer?
A key programmer is a device that allows you to reprogram the transponder on the car or truck fob or key. This is required when a new key or fob has to be programmed. It is also necessary when an existing fob or key has been stolen or lost. The device basically reprograms digital signature on the chip inside the key to match the signature of the vehicle and enable it to start.
Some vehicles come with electronic immobilizer systems that stop theft by stopping the engine from starting if it is not equipped with the correct fob or key. The system checks if the key or fob is digitally signed. 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 is now required for various models of vehicles by the manufacturer.
These anti-theft systems can be controlled by a module that is installed in the vehicle's engine instrument panel, instrument panel, or ignition lock. In certain instances, these modules require special keys that are specifically programmed by a professional to function with the anti-theft system. This is usually done by a dealership or locksmith using computers.
While it is possible to reprogramme some fobs and keys at home, it is not recommended unless you're an experienced automotive technician. A wrongly programmed key can cause the vehicle not to start, fail to run or even break. The majority of auto makers have a specific method for programming these kinds of keys.
It is recommended that if you plan to offer key programming as part of your service offering, you obtain an LSID. This credential allows you access to a database of key and immobilizer codes and details about the product. This access allows you to quickly and easily program and test new key for customers. In addition, it gives you important support and documentation that can aid you in your day-today business operations.
How do I program the key?
A key programmer is a piece equipment that allows you to reprogram your car's keys. It reads data from the microchip inside the key, and add new information to the chip. This will permit you to use your key and will ensure it is working correctly. The process of using a programmer can be a bit complicated and requires technical expertise. Therefore, before attempting to do this on your own you should first talk to an expert locksmith or locksmith for directions.
You can purchase a key programer and have it professionally programmed at a cheaper cost than what you would pay an auto dealer to do the job for you. But, remember that not all key programmers will be compatible with your vehicle. You must ensure the compatibility of the item with the model of your car before purchasing.
Dealers will usually need to reprogramme your key fob. This is because the key fob will need to be reprogrammed with the specific information for your car's anti-theft system. A dealer will typically require the VIN number for your vehicle in order to do this, and typically charge a fee to do it. You may be able to reduce the cost by providing the dealer a copy your title that you can get through the DMV in most states.
For some cars you may also be able to reprogram your key if you already have a working key that works with your car. This method is known as the master key method, and it can be applied to certain vehicles in order to program a secondary key. For instance, if you have an GM vehicle, simply insert your working key into the ignition and turn it on until the security light turns off. Once this happens then you can remove your working key, and then insert the new one to program it.
You can also purchase a specialized EEPROM Key Programmer. This is more expensive but more efficient method of programming the car key. However it is a more advanced technology that requires removing the car and reading the information from the microchip in the key. This kind of programming should only be performed by certified automotive technicians who have extensive experience in electronic repairs.
What are the best choices for programmers with a high level of expertise?
There are many alternatives when it comes down to key programmers. Some key programmers are designed for a single use, like generating new keys. Others have diagnostic and service features to make them a multi-purpose tool in the mechanic's shop. XTool is one such manufacturer, producing a selection of key programmer tools that are well-received from customers. The products are affordable and are based on a customer-centric approach which makes them simple to use.
One of their most popular models is the XTOOL Inplus IP616, which has been rated as one of the best in its class. It offers an easy, user-friendly interface and super clear instructions that assist users in the process of programming a brand new key. There are two ways to do this: by vehicle or via type. The first is easier and is suitable for beginners and home mechanics, while the second is more advanced and requires more experience.
Autel MaxiIM IMM608PRO Auto Key Programmer is a great option. It is a more recent model that provides more performance and stability. It comes with a powerful IMMO feature and the ability to perform diagnostics at the level of OE. This makes it perfect for professionals who work in the automotive industry.

It also comes with additional useful features, including reading mechanical key codes, or dealer tool security codes. It also reads CAN data from some Peugeot and Citroen automobiles, and comes with a long-lasting, rechargeable battery.
Despite its impressive features, the XTOOL Inplus IP616 remains relatively affordable. It's available for less than $500, which makes it a fantastic option for any mechanic or DIY repairman. It comes with a rechargeable battery and a fast boot-up time and supports both OBD CAN protocols.

Which key programmer is right for me?
It all boils down to what kind of work you perform and what you expect from your key programmer. If you're an auto locksmith, then you might need an instrument that can program a wide range of vehicles. For instance the Smart Pro or Autel IM608 Pro. They're designed to do everything from reading/writing on the key to ECU coding and some OE level programming.
There are alternatives for mechanics that do not require the entire apparatus. One of these is the Xtool Pad3 tablet key programmer. It is designed to perform key programming, but it also has advanced functions like oil service light reset, EPB reset, battery reset and throttle body reset.
