How to Program a Car Key
Modern cars use more than just a key to start the engine. They also come with a remote that can lock and unlock doors. These key fobs must be programmed to function.
Some keys for cars can be preprogrammed by the owner himself, but it is best to speak with a professional. This will help prevent any possible damage to the computer system, and also ensure that the new key works correctly.
How do you program the key
Most cars had basic key systems prior to the turn of the 21st century. The keys were made of metal and had grooves to match the internal components of the ignition cylinder. As technology improved, more and more automobile manufacturers began to combine electronic and physical protocols to stop theft. Key systems, also known as transponder keys or chips keys, are designed to make it more difficult for thieves to open an automobile.
The key chips inside the keys have a specific serial number that sends signals to the receiver in your car. The signal is compared with the car's computer when it is received. If the codes are compatible, then your car will start. If not, it won't start at all. This is one of the primary reasons to keep a spare key on your vehicle, particularly when you use transponder-based systems.
You'll need special equipment to learn to program keys. You'll also need to purchase a blank key that matches your specific make and model. They can be purchased from an auto dealership or from a locksmith, but you must make sure that they are the right ones. If you attempt to use a key that is from an alternative model, it will not work.
To start the process, you need to insert the new key into the ignition and turn it to the "on" position. You'll need to keep the key in this position for about 10 minutes and 30 seconds. Once the time is up, you can remove the key and check whether the security light on your dashboard went out. If it did not then you'll need to repeat the procedure a third time.
This method is only compatible with GM vehicles and it's not foolproof. If you're looking for a more secure and reliable option go to a locksmith or dealer to get your car programmed using an embedded chip. They have the tools and equipment needed to access your car's onboard diagnostics port and make the switch.
Keyless Entry Systems
Keyless entry systems permit property access without the requirement for an actual credential. They make use of sensors in combination with an onboard computer for security. This lets you manage the system and monitor activities from anywhere on your property, and removes the requirement for keys or locks. The system is also able to detect and disable stolen or lost cards. The most recent models also permit remote management and configuration and are cloud-based.
Most modern cars come equipped with a keyless entry system. To make this work, the vehicle emits radio signals that are picked up by a specific key fob. The signals are then compared to the code stored in the car's computer and, if all is in order the car will be able to unlock. The car won't start in the event that the signals are not identical. There are a variety of ways to program your new key fob, if it's not programmed yet.
You'll first need to make sure that all doors except the driver's door are locked. You'll need the original key fob along with any extras that you want to program.

Transponder Keys
Transponder keys, also referred to as chip keys, have a microchip built into the head of the key. The antenna ring transmits electromagnetic energy to the transponder when the key is inserted into the ignition lock barrel. This energy is absorbed by the chip, which then transmits a radio frequency signal with an identification code that is matched up to the unique digital serial number that is stored in the car's computer system. This will prevent any unauthorised attempts to start the car, because only a valid key can perform the task.
This type of technology is thought to be more secure than a traditional car key, as it makes it more difficult for a thief "hot wire" the vehicle to start it. But it's not foolproof and thieves have discovered ways to trick and defy the system - so that even cars with transponder keys aren't protected from theft.

The key fobs have electronic chips in them which communicate with the car's receiver using radio signals. The car's computer then compares this key's code with the one stored in its database. If the codes are the same the car will begin. If not, the car will not start or fail to start.
