How to Program a Car Key
Modern cars have more than just a key which will start the engine. They also come with a remote control that allows you to lock or unlock doors. These key fobs have to be programmed to function.
Some car keys can be programmed by the owner himself, but it's best to consult with an expert. This will help protect against any possible damage to the computer system and also ensure that the new key is working properly.
How do you program the key
The majority of cars had basic keys systems up until the turn of 21st century. Keys themselves were metal and had grooves that corresponded to the internal components of the ignition cylinder. As technology improved, more and more automobile manufacturers began to combine electronic and physical protocols to avoid theft. Key systems also known as transponder keys or chips keys are designed to make it more difficult for thieves to start a vehicle.
The key chips inside the keys have a unique serial number that transmits a signal to the receiver inside of your car. The signal is compared with an identifier in the computer of the car when it is received. If the codes match, then the car will start. If the codes aren't compatible, your car won't even start. This is one of the main reasons you should keep a spare key on your vehicle, especially when you use an electronic transponder.
If you want to learn how to program a key, you'll need certain equipment. You'll need to buy a blank key that is compatible with your car model and make. You can purchase them from the locksmith shop or at a car dealership, but it's essential to purchase the correct keys. If you use a key for another model, it won't function.
To begin the process, insert the new key into the ignition and turn 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 has expired you can take off your key and see if the security indicator on your dashboard has gone out. If it didn't then you'll have to do it again for another time.
This method is only compatible with GM vehicles, and isn't 100% secure. If you want a more reliable and secure solution then you should visit an auto locksmith or dealer to have your car programmed with an embedded chip. They will 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 give property access without requiring an actual credential. Security is achieved through sensors that are combined with an onboard computer. This allows you to control the system and monitor activities from anywhere on the property, and does away with the requirement for locks or keys. The system is also able to detect and disable stolen or lost cards. In addition, the latest models are cloud-based and permit remote management and configuration.
Most modern cars are equipped with the keyless entry system. To make this work the car emits radio signals that are detected by a particular key fob. These signals are then compared to the correct code that is stored in the car's system, and when everything is in order the car will be able to unlock. If the signals do not match and the car does not start. If your key fob isn't already programmed, you can follow several steps to program it.
First, you'll need ensure that all doors are locked except for the driver's side. You'll need the original key fob and any additional devices you want to program.

Once you've got the proper tool, follow the instructions of the manufacturer to begin changing the program of your key fob. The process is usually fast and easy. For example, you might be asked to insert your new key into the ignition while keeping all doors shut and then press a button on the key fob within a brief time. The car could respond by cycling doors or emitting an audible chime as an indication that the key has been successfully programmed.
Many locksmiths employ special tools to bypass the EEPROM security built into your car's remote or key fob. But, this is an extremely risky option and could lead to the possibility of destroying the data stored on your car's computer. This is best left to a professional who can minimize the risk of data corrupting and ensure that your keys are programmed correctly.
Transponder Keys
Transponder keys are also referred to as chip key. They have a microchip embedded in the head of keys. The antenna ring transmits electromagnetic energy to the transponder whenever the key is put into the barrel of the ignition lock. This energy is absorbed into the chip and it transmits an audio frequency signal that contains an identification code that matches up to the unique serial number that is stored in the car's computer system. This stops unauthorized attempts to begin the car as only the correct keys will be able.
This type of technology is thought to be more secure than a conventional car key, as it makes it more difficult for a criminal to "hot wire" the vehicle to start it. But 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.
You may be able program a transponder key by yourself if you have an appropriate key programmer for your car. The key programmer will come with a user guide that walks you step-bystep through the process. Follow the instructions and turn on the security lights on your dashboard before you start your engine.

To be able to make this process work you'll need at least two key fobs that are functioning for your vehicle. It is essential to have two spare keys available.
The key fobs contain electronic chips that communicate via radio signals with the car's receiver. The computer in the car then compares the code on the key to read more the one stored in its database. If the codes match, the car will start. If not, the vehicle will not start or fail to start. Luckily, most of these electronic keys can be replaced and programmed by a professional auto dealer or a locksmith with the right equipment.
