How to Program a Key The majority of modern keys for vehicles need to be programmed before they will work. This can be done by a parts department of a dealer or a professional locksmith using the appropriate tools. Key programming is required in two situations when an additional key is added, or when all working keys are lost. The steps for each vary slightly however, they can be broken into the following categories: Keys In data structures, a key is an identifier that is unique to an entire set of data. Sometimes, the key is part of the data itself (as in primary keys in a relational database) however, it could also be segregated from it. Keys are used for finding information quickly, without needing to search the entire structure. As a guide or starting point: this process will work with most American cars and some European models that don't use VATS. You'll need a working key and the VIN for your vehicle. The VIN number is typically found on official documents such as the title, registration card or insurance card. Be aware that some car manufacturers may require two keys to work before you can use the method. Chips The transponder chip is one that is included in many car keys in the present. When you insert your key into the ignition lock and turn it to ON, the antenna sends the radio frequency signal to the transponder along with the identification code. The chip sends a burst energy back to the ignition lock, which it utilizes to determine whether the key is able to start the vehicle. The car won't start with a key that isn't transponder-compatible, if it's been set up to only accept certain types of chips. This is a method of preventing car theft, as the only person who can start your vehicle with a stolen key is the original owner. There are ways to program keys without the transponder that was originally used. You will need to first find a blank key with the appropriate chip for your car model. https://telegra.ph/Why-Car-Key-Programmed-Is-Your-Next-Big-Obsession-09-05 are available in most auto and hardware parts stores. The next step is to connect to the electronic controller unit (ECU). Refer to the owner's guide, or a professional mechanic to find out how to do it. You may need an appropriate programming tool to connect the blank key to the ECU. Once you have the blank key as well as the programming tool, you are able to follow a simple process to pair the two.
