Car key programmers allow mechanics to program an electronic key to work with your car. While keys can be obtained from a locksmith, mechanic, or dealership, they will need to be programmed either way. Having one in your repair kit can help save you the time and hassle of getting a new key from a locksmith if yours is lost or broken.
Most modern vehicles have a transponder chip inside the key. The chip is used to verify the authenticity of the key when it is inserted into the vehicle’s ignition. If the chip fails to provide the correct code when requested, the vehicle’s anti-theft system will activate and prevent the engine from starting. This is usually accomplished by disabling the starter motor, fuel injection, or engine ignition (sometimes all three at the same time).
This is where key programming comes in. Whenever a new key is made for a car, it must be programmed into the anti-theft system before the engine can be started. It will still be able to open the door using the mechanical key blade, but when inserted into the ignition it will not work unless the chip has been programmed.
Additionally, sometimes keys that have been used for years may suddenly stop working and need to be reprogrammed. Sometimes, it can also be caused by a faulty transponder chip, in which case the chip needs to be replaced and then reprogrammed.
Key programming is usually accomplished by connecting a key programming tool to the vehicle via a diagnostic socket (OBD plug). There are many different types of programmers on the market, some require a laptop to run, others are standalone devices or touchscreen tablets.

The basic principles for programming new keys are as follows:
1. Determine the type of key and transponder chip required
First, you must determine the type of key blank you need. There are tools, such as the Xhorse XDKR00GL Key Reader , that can be used to quickly determine the type of key and even the bite (cut). Alternatively, it must be looked up manually using the make, model, and year of the vehicle.
2. Cut out the new key
Make new keys. If the original key is available then you can duplicate the blade. If you don’t have a blade to copy with, then you can use a Lux tool to decode the lock. These highly specialized tools probe the inside of your lock and tell you the information you need to create a working key!
3. Insert the transponder chip
Next, insert the correct type of transponder chip into the new key’s plastic head. Most keys have a slot that the chip can be inserted into, and then a plastic plug that seals the chip inside.
4. Connect your key programmer to the vehicle
Now connect your key programming tool to the vehicle via OBD and insert the new key into the ignition. It won’t start the car, but it will allow you to turn on the ignition and turn on power to the car’s systems.
5. Program the key
Once you enter your vehicle details, your programming tool will be connected to the vehicle and you will be able to program your new key. The actual programming steps will vary slightly depending on the programming tool you use, but the general principles are always the same.
6. Test Key
After programming, test the key to make sure it is working properly
