How to program a Key
The majority of cars had basic key systems until the turn of the 21st century. The keys were made of metal and had grooves to match the internal components in the ignition cylinder. As time passed and technology advanced and improved, automobile manufacturers began to combine physical and electronic protocols to protect against theft. These key systems are known as transponder keys or chip keys, and are designed to make it more difficult for thieves to open the vehicle.
The key chips have an unique serial number which transmits a signal to the receiver inside your car. When the signal is received it is compared to an existing code in the car's computer. If the codes are identical, your car will begin. If not, it will not start at all. This is the reason you should keep an extra car key particularly if your system is transponder-based.
If you're looking to learn how to program keys, you'll need some special equipment. You'll need to buy a blank key that is compatible with the model and make of your car. You can purchase them from an auto locksmith or a locksmith dealership, but it's important to purchase the correct keys. If you use a key from another model, it will not function.
To begin the process, simply insert the new key into the ignition and switch it to the "on" position. You'll need to keep the new key in this position for about 10 minutes and 30 second. Once the time is up, you can remove the key and observe whether the security indicator on your dashboard went out. If not then you'll need to repeat the process for a third time.
This method is only compatible with GM vehicles and isn't 100% secure.

Keyless Entry Systems
Keyless entry systems give access to your property without the need for an actual credential. They make use of sensors in combination with an onboard computer for security. This allows you to control the system and monitor its activity from anywhere within the property, and it does away with the need for keys or locks. The system is also able to detect lost or stolen cards and then deactivate them. In addition, the newest models are cloud-based and permit remote management and configuration.
Most modern cars are equipped with a keyless entry system. The system works by sending radio signals that are picked up using a special keyfob. These signals are then compared to the correct code in the car's computer and if everything is in order the car will be able to unlock. The car won't start in the event that the signals are not the same. If your key fob is not already programmed, you may follow a series of steps to program it.
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 other devices you wish to program. You could also check with the local auto parts store, as they may have the right tool to program your car. If these steps don't work, you'll need to consult your owner's manual or an expert locksmith.

You may be instructed to insert the new key into the ignition when all doors are shut, and then press the button on the keyfob after a certain time period. The car may then respond by cycling the door locks or emitting a sound to signal that the key has been successfully programmed.
Many locksmiths employ special tools to get around the EEPROM security that is built into the remote of your car or key fob. This is a dangerous method and can corrupt the data in your car's computer. It's best to have a professional handle this as they'll be able to reduce the risk of data corruption and also ensure that your keys are correctly programmed.
Transponder Keys
Transponder keys, sometimes referred to as chip keys, are equipped with 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 barrel of the ignition lock. The energy is absorbed by the chip and sends back the radio frequency signal, which includes an identification code that is matched with the unique serial number of the car's computer system. This prevents an unauthorized attempt to start the car, because only a valid key will be able to do so.

This technology is thought to be more secure than a traditional car key, as it makes it harder for thieves to "hot wire" the vehicle to start it. But it's not foolproof, and thieves have found ways to trick and defy the system - so that even cars with transponder keys aren't protected from theft.
You might be able to program a transponder key by yourself with a key programmer compatible with your vehicle. The key programmer should include an instruction manual that will guide you through the procedure of programming your key. Once you have your key and key programmer, follow the directions carefully and make sure the security light on your dashboard is on prior to turning your engine on.
If you're not comfortable with the use of a key programmer or if your vehicle includes more advanced features such as remote head keys or smart keys, you can turn to a professional locksmith for assistance. They'll have the appropriate tools and equipment to cut your blank key, erase your old one from the computer in the car and then program the new key so that it will work correctly. This will save your time and money, and will help keep your car's security system functioning as it should. Plus, it's a lot safer than trying to do it yourself! Making use of the wrong key programmers or following unofficial instructions could cause a problem with the information stored in your car's system, and result in your new key not working.
Remotes
You may need to reprogram your car keys if they aren't working. This is a simple procedure for most modern vehicles that have key fobs. However, certain models are more complex and require programming with the aid of an additional device that's typically available from the dealer or auto locksmiths.
Fortunately, most modern car manufacturers have made their key systems more secure to decrease the risk of theft from vehicles. The key system is designed in a way to avoid hot-wiring which is the practice of using a key from an other vehicle to start the engine of your car. Therefore, you'll need at minimum two working key fobs for your vehicle to be able to use the system. It is essential to have at least two spare keys available.
The key fobs have electronic chips that transmit radio signals with the car's receiver. The car's computer then compares the key's code to the one stored in its database. If the codes match the car will begin. If the codes do not match the car won't start or remain dead. The majority of these electronic keys can be programmed and replaced by an expert locksmith or auto dealer with the right equipment.
If you're able to find an inexpensive car key programmer online or at an auto parts store, the process should be fairly straightforward. You'll have to follow a set of instructions that includes inserting the ignition key and turning it on without actually starting the vehicle, and then shutting off the key. You'll have to repeat this process a certain number of times within a certain time frame for your vehicle to enter programming mode. The door locks will turn on and off or a chime will sound.
Some modern cars are only capable of programming using a device connected to the onboard diagnosis port or EEPROM programming. Unfortunately, most of these tools are incredibly expensive, which makes them unaffordable for the majority of car owners. So, many experts in the field recommend to consult a professional auto dealer or locksmith to program your keys.
