How to program a Key
The majority of cars had basic keys systems up until the turn of 21st century. Keys themselves were metal and featured grooves that matched the internal components of the ignition cylinder. As time passed and technology improved as it did, automobile manufacturers began blending electronic and physical protocols to prevent theft. These key systems are known as transponder keys or chip keys, and are designed to make it more difficult for thieves to get into the vehicle.
The key chips come with an unique serial number which transmits a signal to the receiver in your car. When the signal is received it compares it with the code that is stored in the car's computer. If the codes are identical, your car will begin. If the codes don't match, your car won't even start. This is one of the main reasons you should keep a spare key on your car, especially in the case of transponder-based systems.
You'll require specialized equipment to learn to program keys. You'll also require an uncut key that matches your specific model and make. You can purchase these at an auto locksmith or a locksmith dealership, but it's crucial to get the right ones. If you try to use a key from another model, then it will not work.
Begin by putting the new key into the ignition and turning it to "on". You will need to leave the new key in this position for approximately 10 minutes and 30 second. Once the time is up you can take out the key and check whether the security light on your dashboard was gone. If not, you'll need repeat the process a third time.

Additionally, the most recent models are cloud-based and allow for remote management and configuration.
Most modern cars come equipped with an entry system that is keyless. This system works by emitting radio signals that are picked up using a special keyfob. The signals are compared to the code that is stored in the car's computer, and if all is well, the car will unlock. The car won't start in the event that the signals are not identical. If your key fob isn't already programmed, you may follow a few steps to program it.
The first step is to ensure all the doors are locked, except for the driver's side. Also, you'll need the original key fob, as well as any extras you want to program. You can also visit your local auto parts shop to see if they have the appropriate tool for your vehicle. If these steps don't work, you'll have to check the owner's manual, or an expert locksmith.

Transponder keys, also known as chip keys, are equipped with a microchip built into the head of the key. When the key is placed in the ignition lock barrel and turned to ON, the antenna ring sends an energy burst through the transponder chip. This energy is absorbed by the chip, which then transmits a radio frequency signal with an identification code that matches with the unique serial number of the car's computer system. This stops unauthorized attempts to begin the car as only the proper keys will be able to do so.
This technology is believed to be more secure than traditional car keys because it makes it much difficult for thieves to "hot wire" a vehicle and get it started. However, it's not foolproof and thieves have discovered ways to evade and defeat the system - so that even vehicles that have transponder keys aren't safe from theft.
Depending on the brand and model of your vehicle, you may be capable of programming a new transponder key by yourself by using a key programming device that's compatible with your specific car.

If the codes don't match the car won't start or remain dead. Luckily, most of these electronic keys can be replaced and programmed by a professional locksmith or an auto dealer with the right equipment.
