How to Program a Car Key
Modern cars use more than just a key to start the engine, they also come with a remote that can lock and unlock doors. Key fobs have to be programmed to work properly.
Some car keys can be preprogrammed by the owner themselves but it is best to speak with a professional. This will avoid any damage to the computer system of the car and ensure that the key works correctly.
How to program a Key
Most cars had basic key systems up until the turn of the 21st century. Keys were made from metal and had grooves to correspond with the internal parts of the ignition cylinder. As time passed and technology improved as it did, car manufacturers began blending physical and electronic protocols to protect against theft. These key systems are called transponder keys or chip keys and are designed to make it difficult for thieves to open the vehicle.
The key chips have 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 similar then your car will begin. If the codes aren't compatible, your car will not even start. This is why you should keep a spare car key, especially if your system is based on transponders.
You'll need special equipment to learn to program keys. You'll also need the blank key for your specific make and model. They can be purchased from the dealership or through locksmiths but you must make sure that they are the right ones. If you use a key that is for another model, it won't work.
Start by inserting the new key in the ignition and turning it "on". You'll need to leave the key in this position for approximately 10 minutes and 30 seconds. After the time has expired, you can remove the key and check whether the security indicator on your dashboard went out. If it didn't then you'll have repeat the process a third time.
This method is only compatible with GM vehicles and isn't completely secure. If you're looking for a reliable and secure solution then you should visit a locksmith or a dealer to have the vehicle programmed with an embedded chip. They have the tools and equipment needed to connect to the diagnostics port in your vehicle and make the switch.
Keyless Entry Systems
Keyless entry systems allow property access without the need for an actual credential. They use sensors in combination with an onboard computer to offer security. It is possible to manage and monitor the system from anywhere within the property. Keys and locks are not required. The system is also able to detect and block stolen or lost cards. The latest models also support remote management and configuration and are cloud-based.
Most modern cars come equipped with the keyless entry system. The system works by sending radio signals that are received by a special keyfob. These signals are then compared against the correct code in the car's computer and when everything is in order the car will start to unlock. If the signals do not match then the car won't start. There are several steps you can follow to program your new key fob if it isn't already programmed.
First, you'll need make sure that all doors are locked, with the exception of the driver's side. Also, you'll need the original key fob along with any additional keys you want to program. You can also try the local auto parts store for the right programming tool for your car. If none of these methods work, you'll have to check the owner's manual, or an expert locksmith.

It is possible to be instructed to put the new key in the ignition when all doors are shut, and then press the button on the keyfob after a certain time period. The car could then respond by turning off the door locks or emitting a sound to signal that the key was successfully programmed.
Many locksmiths are equipped with special tools that permit them to bypass the built-in EEPROM security on your car's key fob or remote. But this is an extremely risky procedure and comes with the possibility of destroying the data stored on the computer in your car. It is recommended to have an expert handle this because they will be able to reduce the chance of data corruption and also ensure your keys are properly programmed.
Transponder Keys
Transponder keys, also referred to as chip keys, have a microchip embedded in the head of the key. When the key is placed in the barrel of the ignition lock and turned into the ON position the antenna ring emits a burst of electromagnetic energy through the transponder chip. The energy is absorbed by the chip and sends back an audio frequency signal that contains an identification code that matches with the unique serial number of the car's computer system. This will prevent any unauthorized attempts to start the car, since only the right key will be able to perform the task.
This type of technology is thought to be more secure than a traditional car key because it makes it harder for a criminal to "hot wire" the vehicle and start it. It's not foolproof, and thieves have found ways to trick and defeat the system. So even cars equipped with transponder keys aren't safe from theft.
Depending on the make and model of your car You may be able to program a new transponder by yourself with a key programer that is compatible with your specific car. The key programmer will come with a user guide that will guide you step-by-step through the procedure. Follow the instructions and switch on the security light on your dashboard prior to beginning your engine.
