How to Program a Car Key
Modern cars come with more than just a single key to start the engine. They also have a remote that can lock and unlock doors. These key fobs have to be programmed to function.
Some car keys can be programmed by the owner himself, but it is recommended to consult an expert. This will help prevent any possible damage to the computer system and ensure that the new key is working properly.
How to program a key
Most cars had basic key systems until the turn of 21st century. The keys were made of metal and incorporated grooves to correspond to the internal parts in the ignition cylinder. However, as time progressed and technology advanced and improved, automobile manufacturers began blending electronic and physical protocols to protect against theft. These key systems are known as transponder keys or chip keys and they're designed to make it more difficult for thieves to open the vehicle.
The key chips that are in the keys have a specific serial number, which transmits an electronic signal to the receiver inside of your car. The signal is then compared to a code in the car's computer when it is received. If the codes match, then your car will begin to start. If the codes don't match, your car will not even start. This is one of the main reasons why you should always keep a spare key on your vehicle, particularly when you use transponder-based systems.
You'll require special equipment to be able to program keys. You'll need a blank key that is compatible with the car's model and make. You can buy them at an auto locksmith or a locksmith dealership, but it's important to buy the right one. If you attempt to use a key that is from another model, then it won't work.
Begin by putting the new key in the ignition and turning it "on". You'll need to keep the key in this position for around 10 minutes and 30 seconds. Once the time is up, you can remove the key and see whether the security light on your dashboard was gone. If it didn't go out, you will need to repeat the process three times.
Remember that this method will only work on GM vehicles however it isn't completely secure. If you're looking for a more secure and reliable solution then you should visit a locksmith or dealer to have your vehicle programmed with an embedded chip. They will have the tools and equipment to connect to the onboard diagnostic port of your car and make the switch.
Keyless Entry Systems
Keyless entry systems allow access to properties without the need for a physical credential. Security is provided by a combination between sensors and an onboard computer. This lets you manage the system and monitor activities from anywhere within the property, and it does away with the requirement for keys or locks. The system can also detect lost or stolen cards and deactivate them. The newest models also allow remote management and configuration as well as are cloud-based.
Modern automobiles are equipped with keyless entry systems. To enable this feature the car emits radio signals that are picked up by a specific key fob. These signals are then compared to the correct code that is stored in the car's system, and if everything is in order the car will start to unlock. The car will not start if the signals are not identical. If your key fob has not been already programmed, you may follow several steps to program it.
First, you'll need to ensure all the doors are locked, with the exception of the driver's side. You'll need to have the original key fob as well as any additional devices you want to program.

The car might respond by turning off the door locks or emitting an audible chime as an indication that the key was successfully programmed.

However, this is a risky method and comes with the possibility of destroying the data on your car's computer. This should be left to a professional who can lower the chance of data corruption and make sure that your keys are programmed correctly.
Transponder Keys
Transponder keys, also known as chip keys, come with an embedded microchip in the head of the key. When the key is inserted into the barrel of the ignition lock, and then turned to ON the antenna ring emits an energy burst through the transponder chip. The chip absorbs this energy, and then transmits a radiofrequency signal which contains an identification number. This code matches the unique serial numbers of the computer system of the car. This stops any attempts by anyone else to start the car, as only proper keys will be able to do so.
It is believed that this technology will be more secure than traditional car keys because it makes it much more difficult for thieves to "hot wire" an automobile and start it. But it's not foolproof and thieves have discovered ways to evade and defeat the system - so that even vehicles with transponder keys are not safe from theft.
Based on the make and model of your car, you may be capable of programming a new transponder key yourself using a key programmer that's compatible with your specific car.

They'll have the appropriate tools and equipment to cut your blank key, delete your old one from the computer in your car, and then program the new key so that it works properly. This will save you time and money, and keep your car's safety system working as it should. automotive key programming is also safer than making it yourself.

The key fobs have electronic chips that transmit radio signals with the car's receiver. The computer in the car then compares the key's code to the one in its database. If the codes match the car will begin. If not, the vehicle will not start or fail to start.
