How to Program a Car Key
Modern cars come with more than a key to start the engine. They also come with a remote that can lock and unlock doors. These key fobs must be programmed to work.
Some car keys can be programmed by the owner, however it is best to speak with an expert. This will protect against any possible damage to the computer system, and also ensure that the new key is working properly.
How to program a Key
Most cars had basic key systems prior to the turn of the 21st century. Keys were made from metal and featured grooves that correspond with the internal parts in the ignition cylinder. As technology improved, more and more car makers began to mix physical and electronic protocols to stop theft. These key systems are referred to as transponder keys or chip keys and are designed to make it more difficult for thieves to get into the vehicle.
The key chips in the keys have a specific serial number that sends an electronic signal to the receiver inside of your car. When the signal is received it compares it with the code that is stored in the car's computer. If the codes are compatible, then your car will begin to start. If not, it won't start at all. This is one of the main reasons to keep a spare key on your vehicle, especially in the case of transponder-based systems.
If you want to learn how to program keys, you'll require certain equipment. You'll also need to purchase the blank key for your particular model and make. These can be purchased at the dealership or through a locksmith, but you must make sure they're the right ones. If you use a key from another model, it will not work.
To start the process, you need to insert the new key into the ignition and turn it to the "on" position. You will need to leave the new key in this position for about 10 minutes and 30 seconds. After the time has passed you can take off your key and see if the security indicator on your dashboard has gone out. If not then you'll need to repeat the process for a third time.
Be aware that this method will only work with GM vehicles, and it's still not foolproof. If you're looking for a more secure and reliable option, you should visit an expert locksmith or dealer to have your car programmed with chips. They will have the tools and equipment needed to access the onboard diagnostic port of your car and make the change.
Keyless Entry Systems
Keyless entry systems provide access to your property without the need for an actual credential. They make use of a combination of sensors and an onboard computer to offer security. It is possible to manage and monitor the system from anywhere in the property. Keys and locks are not required. The system can also detect and disable stolen or lost cards. In addition, the latest models are cloud-based, allowing for remote management and configuration.
Most modern cars are equipped with the keyless entry system. The system works by emitting radio signals that are detected by a special keyfob. The signals are then compared with the correct code stored in the car's computer and if everything is in order, the car will unlock. If the signals do not match then the car won't start. 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 can also check the local auto parts store to determine if they carry the appropriate tool for your vehicle. If these steps don't work, you will need to consult your owner's manual or an expert locksmith.
Once you have the right tool, follow the manufacturer's instructions to begin programming your key fob. The process is usually quick and easy. For instance, you could be instructed to insert your new key into the ignition with the doors shut, and then press an appropriate button on the fob within a brief time frame. The car may respond by reversing the door locks or emitting an audible chime as a sign that the key has been successfully programmed.
Many locksmiths employ special tools to bypass the EEPROM security that is built into the remote of your car or key fob. However, this is an extremely risky procedure and could lead to the possibility of corrupting the data on your car's computer. This should be left to a professional who can minimize the risk of data corruption and make sure that your keys are correctly programmed.
Transponder Keys
Transponder keys are also known as chip keys. They have embedded microchips in the head of the keys. When the key is inserted into the barrel of the ignition lock and then turned to ON the antenna ring transmits an electromagnetic energy blast through the transponder chip. This energy is absorbed into the chip and it transmits the radio frequency signal, which includes an identification code that is matched with the unique digital serial number in the car's computer system. This will prevent any unauthorized attempts to start the car, as only the correct key can start the car.
It is believed that this technology will be more secure than traditional car keys because it makes it more difficult for thieves to "hot wire" an automobile and get it started. But it's not foolproof and thieves have discovered ways to trick and defy the system - so that even vehicles with transponder keys aren't protected from theft.
Based on the make and model of your car, you may be capable of programming a new transponder key yourself by using a key programming device that's compatible with your specific car. The key programmer will come with a guide that walks you step-bystep through the process. Follow the instructions and turn on the security light in your dashboard prior to starting your engine.
If you're not comfortable programming keys, or if your car includes more advanced features such as remote head keys or smart keys, you may turn to a professional locksmith help. They'll have the tools and equipment necessary to cut a blank key, delete the old one from the computer of the car, and then program the new key for it to work correctly. This will save your time and money, and will ensure that your car's security system functioning exactly as it should. Plus, it's a lot safer than trying to do it yourself! If you choose the wrong key programmer or follow a guide that is not official, the information in your car's computer could be damaged and the new key will not function.

The key fobs have electronic chips that transmit radio signals with the car's receiver. The computer compares the code of the key with the database. If the codes match the car will begin. If the codes do not match, the car will not start or remain dead. Most of these electronic key can be programmed and replaced by a professional locksmith or auto dealer with the proper equipment.
