How to program a Key
Most cars had basic key systems up until the turn of the 21st century. The keys were made of metal and featured grooves that match the internal components in the ignition cylinder. As time went on and technology improved as it did, car manufacturers began blending electronic and physical protocols to protect against theft. These key systems are known as transponder keys or chip keys, and are designed to make it harder for thieves to start the vehicle.
The key chips in the keys have a specific serial number that sends an electronic signal to the receiver inside your car. The signal is compared with a code in the car's computer when it is received. If the codes are identical the car will begin to begin to start. If not, it won't start at all. This is the reason you should keep an extra car key, especially if your system is based on transponders.
If you're looking to learn how to program keys, you'll require certain equipment. You'll also need an uncut key for your specific make and model. They can be bought at a dealership or by a locksmith but you must make sure they're the right ones. If you attempt to use a key that is from an alternative model, it won't work.
Start the process by inserting the new key into the ignition and turning it to "on". You'll need to keep the new key in this position for around 10 minutes and 30 seconds. Once the time has expired you can take off your key and see if the security indicator on your dashboard has gone out. If it didn't you'll have to repeat the procedure a third time.
This method is only compatible with GM vehicles and isn't 100% secure. If you're looking for a more reliable and secure solution then you should visit a locksmith or a dealer to get your vehicle programmed with an embedded chip. They have the tools and equipment needed to access the diagnostic port on your car's motherboard and make the change.
Keyless Entry Systems
Keyless entry systems permit access to property without the requirement of an actual credential. They utilize sensors in combination with an onboard computer to provide security. It is possible to manage and monitor the system from anywhere within the property. Keys and locks are not required. The system is also able to detect and deactivate lost or stolen cards. The most recent models also permit remote management and configuration, and are cloud-based.
Modern cars are equipped with keyless entry systems. The system works by emitting radio signals which are picked up using a special keyfob. The signals are compared with the code that is stored in the car's computer and, if all is well, the car will unlock. If the signals do not match, the car will not start. There are several ways to program your new key fob if it's not already programmed.
You'll first need to make sure that all doors, except the driver's door are locked. You'll also require the original key fob along with any additional keys you'd like to program.

The car might then respond by cycling the door locks or generating a chime to signal that the key was successfully programmed.
Many locksmiths are equipped with special tools that let them bypass the built-in EEPROM security in the car's key fob or remote. However, this is a risky method and has the potential of corrupting the data on the computer in your car. This is best left to a professional, who can lower the chance of data corruption and make sure that your keys are correctly programmed.
Transponder Keys
Transponder keys, also referred to as chip keys, come with an embedded microchip in the head of the key. The antenna ring transmits electromagnetic energy to the transponder whenever the key is inserted into the ignition lock barrel. The chip absorbs this energy, and then transmits a radiofrequency signal that includes an identification code. This code matches the unique serial numbers that are stored in the car's computers. This helps prevent an unauthorized attempt to start the car since only the right key will be able to start the car.
This type of technology is thought to be more secure than the traditional car key because it makes it more difficult for a criminal to "hot wire" the vehicle and start it. However, it's not foolproof and thieves have found ways to evade and thwart the system which means that even cars equipped with transponder keys are not protected from theft.
Depending on the brand and model of your car depending on the make and model of your car, you might be able to program a new transponder key by yourself with a key programer that is compatible with the car you own. The key programmer comes with a user guide that walks you step-bystep through the process. Follow the instructions and switch on the security lights on your dashboard prior to beginning your engine.
You can ask an expert locksmith to assist you if you are not sure about using the key programmer or you own a car that has more advanced features, like remote head keys or intelligent keys.

The key fobs contain electronic chips that communicate using radio signals to the car's receiver. The computer checks the code of the key with the database. If the codes are the same the car will be able to start. If the codes do not match then the car will not start or remain dead. Most electronic keys can be programmed and replaced by an expert locksmith or auto dealer using the appropriate equipment.
