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 need to be programmed correctly.
Certain keys for cars 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 car and will ensure that the key is working correctly.
How to program a key
Up until the turn of the 21st century, most cars used basic key systems. Keys were made of metal and had grooves to correspond to the internal parts in the ignition cylinder. As time passed and technology improved, more and more automobile manufacturers began to combine physical and electronic protocols to stop theft. These key systems are known as transponder keys or chip keys, and are designed to make it difficult for thieves to start the vehicle.
The key chips come with an unique serial number which transmits a signal to the receiver inside your car. When the signal is received it compares it with an existing code in the car's computer. If the codes are compatible, then your car will begin to start. If not, it will not start at all. This is the reason you should keep a spare car key, especially if the system is based on transponders.
If you're interested in learning how to program keys, you'll need some special equipment. You'll need a blank key that matches the car's model and make. You can purchase these at a locksmith or a car dealership, but it's important to buy the right one. If you try to use a key from an alternative model, it won't work.
Begin by putting the new key in the ignition and turning it to "on". It is necessary to keep the key in this position for about 10 minutes and 30 seconds. After the time has expired you can take off the key and observe whether the security light on your dashboard was gone. If it did not, you will need to repeat the procedure for the third time.
Keep in mind that this method will only work with GM vehicles, and it's still not completely secure. If you're looking for a more secure and reliable option go to an auto locksmith or dealer to get your car programmed using an embedded chip. These professionals have the necessary tools and equipment needed to access the diagnostic port on your car's motherboard and then make the change.
Keyless Entry Systems
Keyless entry systems allow access to properties without the requirement of a physical ID. Security is achieved through a combination between sensors and an onboard computing device. This lets you control the system and monitor activities from any place on your property, and removes the requirement for keys or locks. The system can also detect lost or stolen cards and disable them. In addition, the newest models are cloud-based and allow for remote management and configuration.
The majority of modern cars are equipped with the keyless entry system. To enable this feature it emits radio signals that are detected by a particular key fob. The signals are then compared to the code that is stored in the car's computer, and if all is in order, the car will unlock. If the signals do not match, the car will not start. There are a variety of steps you can follow to program your new key fob, if it's not programmed yet.
First, you'll need to make sure that all doors, except the driver's door are locked. You'll need the original key fob along with any extras that you want to program.

Once you have the correct tool, you can begin the reprogramming of your key fob by following the instructions of the manufacturer. This procedure is usually quick and easy. You may be instructed to insert the new key into the ignition while all doors are closed and then press the button on the keyfob after a certain time period. The car might respond by reversing the door locks or emitting an audible sound as a sign that the key was successfully programmed.
Many locksmiths are equipped with special tools that permit them to bypass the built-in EEPROM security on the car's key fob or remote. This is a risky method and can corrupt the data on your car's computer. This should be left to a professional who can minimize the risk of data corrupting and ensure that your keys are properly programmed.
Transponder Keys
Transponder keys, also referred to as chip keys, come with a microchip built into the head of the key. When the key is inserted into the ignition lock barrel and then turned to ON the antenna ring transmits an energy burst through the transponder chip. This energy is absorbed into the chip and it transmits an audio frequency signal that contains an identification code that matches with the unique serial number of the car's computer system. This prevents any attempts by anyone else to start the car, as only correct keys will be able.
This technology is believed to be more secure than conventional car keys because it makes it much difficult for thieves to "hot wire" the vehicle and get it started. It's not foolproof and thieves have found ways of tricking and defeating the system. So even cars with transponder keys aren't safe from theft.
You might be able to program a transponder key by yourself if you have an instrument that works with your car. The key programmer will come with a manual that walks you step-bystep through the process. Follow the directions and switch on the security light in your dashboard prior to beginning your engine.
You can ask an expert locksmith to assist 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. They will have the tools and equipment required to cut blank keys, erase the old one from the computer of the car, and program the new key for it to function properly. This will save your time and money, and will ensure that your car's security system working as it should. It is also safer than doing it yourself. Using the wrong key programmers or following unofficial guides can alter the information stored in the car's system, and result in the new key not working.

This means that you'll need at least two working key fobs for your vehicle in order to be able to use the system. This is one of the reasons why it's recommended to have at least one spare key in your possession.
The key fobs have electronic chips that transmit radio signals with the car's receiver. The computer in the car then compares the code on the key to the one in its database. If the codes match, the car will start. If the codes don't match, the car will not start or will remain dead. Fortunately, the majority of electronic keys can be repaired and programmed by a professional locksmith or auto dealer with the right equipment.
