how To program a car Key (www.google.pt)
Modern cars have more than just a key to start the engine. They also include a remote to lock and unlock doors. Key fobs have to be programmed in order to function properly.
Some car keys can be programmed by the owner himself, but it's best to consult with an expert. This will avoid any damage to the computer system of the vehicle and ensure that the key works properly.
How do you program a key?
Up until the turn of the 21st century, most cars used basic programing key systems. Keys were made of metal and incorporated grooves to correspond with the internal parts of the ignition cylinder. As technology improved the number of car makers began to combine physical and electronic protocols in order to prevent theft. These key systems are referred to 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 transmits a signal to the receiver inside your car. When the signal is received it compares it with a code stored in the car's computer. If the codes are identical then your car will begin. If the codes don't match, then your car will not even start. This is why it is important to keep an extra car key especially if your system is based on transponders.
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 the model and make of your car. You can purchase these at an auto locksmith or a locksmith dealership, but it's important to get the right ones. If you use a key from another model, it will not work.
Start the process by inserting the new key in 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. After the time has expired you can take out the key and see whether the security indicator on your dashboard went out. If it didn't then you'll have to repeat the process for the third time.
Remember that this method can only work on GM vehicles, and it's still not foolproof. If you're looking for a safer and reliable method, you should visit a professional locksmith or the dealer to have your car programmed with chips. These professionals are equipped with the tools and equipment needed to connect to the diagnostic port on your vehicle and make the necessary changes.
Keyless Entry Systems
Keyless entry systems allow access to your property without the need for a physical credential. Security is provided by the combination of sensors and an onboard computer. It is possible to manage and monitor the system from anywhere within the property. Keys and locks are not required. The system can also detect stolen or lost cards and then deactivate them. The most recent models also permit remote management and configuration, and are cloud-based.
Modern cars are equipped with keyless entry systems. To accomplish this, the vehicle 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. The car won't start if the signals are not identical. There are a variety of steps you can take to program your new key fob, if it's not programmed yet.
First, you'll need ensure that all doors are locked, except for the driver's side. You'll need to have the original key fob along with any extras that you want to program.

You might be told to insert the new key into the ignition while all doors are closed, and then press the button on the keyfob after the time frame. The car might respond by turning off the doors or emitting an audible chime, which is an indication that the key has been successfully programmed.
Many locksmiths are equipped with special tools that let them bypass the built-in EEPROM security on your car's key fob or remote. This is a risky method and could cause data corruption in your car's computer. This should be left to a professional who can reduce the risk of data corruption and ensure that your keys are programmed correctly.
Transponder Keys
Transponder keys are also known as chip keys. They are equipped with embedded microchips in the head of keys. The antenna ring transmits electromagnetic energy to the transponder when the key is inserted in the barrel of the ignition lock. This energy is absorbed into the chip, which then transmits a radio frequency signal with an identification code that is matched with the unique digital serial number of the car's computer system. This prevents unauthorized attempts to start the car since only the right key will be able to start the car.
This technology is believed to be more secure than conventional car keys because it makes it difficult for thieves to "hot wire" a vehicle and get it started. It's not foolproof, and thieves have discovered ways of tricking and defeating the system. So even cars equipped with transponder key are not safe from theft.
Depending on the brand and model of your vehicle depending on the make and model of your car, you might be able to program a new transponder key yourself by using a key programming device that's compatible with your particular car. The key programmer should come with an easy-to-follow guide to guide you through the procedure of programming your key. Once you have the key and key programmer, follow the instructions carefully and ensure the security light on your dashboard is turned ON prior to turning the engine on.
You can ask a professional locksmith to help you if you're not confident with a key programmer or if you own a car that has more advanced features, such as remote head keys or intelligent keys programmed. They'll have the right tools and equipment to cut your blank key, erase your old one from the car's computer and then program the new key to ensure that it will work correctly. This will save you time and money and will keep your car's security system functioning just as it should. Additionally, it's much safer than trying to do it yourself! Using the wrong key programmers or following unofficial guides can cause a problem with the information stored in your car's system, resulting in your new key not working.

Key fobs are equipped with electronic chips that communicate using radio signals to the car's receiver. The car's computer then compares this code on the key to the one stored in its database. If the codes match the car will begin. If the codes don't match the car won't start or remain dead.
