How to Program a Car Key
Modern cars have more than just a key that starts the engine. They also come with a remote that can lock or unlock doors. Key fobs need to be programmed in order to function.
Some keys for cars can be programmed by the owner, however it's best to consult with an expert. This will ensure that there is no damage to the computer system of the car and will ensure that the key functions correctly.
How do you program a key?
The majority of cars had basic keys systems prior to the turn of the 21st century. The keys themselves were just metal and had grooves that matched the internal parts of the ignition cylinder. As time passed and technology improved as it did, automobile manufacturers began to combine physical and electronic protocols to protect against theft. Key systems, also known as transponder keys or chips keys, are designed to make it more difficult for thieves to start an automobile.
The key chips inside the keys have a specific serial number that sends a signal to the receiver inside of your car. When the signal is received it compares it with a code stored in the car's computer. If the codes are compatible, then the car will start. If not, it won't start at all. This is the reason you should keep a spare car key, particularly if your system is based on transponders.
If you're interested in learning how to program a key, you'll need some specific equipment. You'll also need to purchase the blank key that matches your specific make and model. They can be bought at the dealership or through locksmiths but you must make sure that they are the right ones. If you use a key from another model, it won't work.
To begin the process, simply 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 approximately 10 minutes and 30 second. After the time has expired you can take off the key and see whether the security light on your dashboard went out. If it didn't you'll have to do it for the third time.
Keep in mind that this method will only work on GM vehicles but it's not completely secure. If you're looking for a more secure and reliable solution then you should visit an auto locksmith or dealer to have the vehicle programmed with an embedded chip. They have the tools and equipment needed to connect to the onboard diagnostics port in your car and make the change.
Keyless Entry Systems
Keyless entry systems provide property access without requiring the use of a physical ID. They utilize sensors in combination with an onboard computer to provide security. It is possible to manage and monitor the system from anywhere in the property. Keys and locks are not required. The system is also able to detect lost or stolen cards and disable them. The newest models also allow remote management and configuration, and are cloud-based.
Most modern cars come equipped with a keyless entry system. To make this work, the vehicle emits radio signals that are detected by a specific key fob. These signals are then compared to the correct code stored in the car's computer, and when everything is in order, the car will unlock. If automotive key programming don't match and the car does not start. If your key fob isn't already programmed, you can follow a series of steps to programme it.
First, you'll need to make sure that all doors, except the driver's door are locked. You'll also require the original key fob, and any other accessories you'd like to program. You can also check your local auto parts store to see if they've got the appropriate tool for your car. If these steps don't work, you will need to consult your owner's manual, or an expert locksmith.

For example, you might be instructed to insert your new key into the ignition while keeping the doors shut, and then press an appropriate button on the fob within a brief time. The car could then respond by adjusting the door locks or generating a chime to signal that the key was successfully programmed.
Many locksmiths have special tools that allow them to bypass the built-in EEPROM security in your car's key fob or remote. However, this is a risky method and comes with the possibility of corrupting the data on the computer in your car. This is best 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 referred to as chip keys. They feature embedded microchips in the head of the keys. When the key is placed in the barrel of the ignition lock, and turned to ON, the antenna ring sends an electromagnetic energy blast through the transponder chip. The energy is absorbed by the chip, which then transmits a radio frequency signal with an identification code that corresponds up to the unique digital serial number in the car's computer system. This stops unauthorised attempts to start the car, as only proper keys will be able to do so.
The technology is believed to be more secure than conventional car keys because it makes it much difficult for thieves to "hot wire" a vehicle and start it. However, it's not foolproof and thieves have discovered ways to trick and defy the system - so that even cars that have transponder keys aren't protected from theft.
Depending on the make and model of your vehicle, you may be capable of programming a new transponder by yourself with a key programer that is compatible with your specific car. The key programmer comes with a manual that walks you step-bystep through the procedure. Once you have the key and a key programmer, follow the instructions carefully and ensure that the security light on your dashboard is turned on prior to turning your engine on.
You can contact an expert locksmith to assist you if you are not sure about using the key programmer or you have a car with more advanced features, like 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 in the car, and then program the new key for it to function properly. This will save your time and money, and will keep your car's security system operating as it should. Plus, it is much safer than doing it yourself. Making use of the wrong key programmers or following unofficial instructions could cause a problem with the information stored in your car's system, and result in the key not functioning.

The keys have electronic chips inside them which communicate with the car's receiver via radio signals. The computer compares the key's code with the database. If the codes match the car will begin. If the codes don't match, the car will not start or remain dead. The majority of these electronic keys can be programmed and replaced by an experienced locksmith or dealer in the field with the right equipment.
