How do you program a key?
Prior to the beginning of the 21st century the majority of cars had basic key systems. The keys were made of metal and incorporated grooves to correspond to the internal parts of the ignition cylinder. As time passed and technology improved as it did, car manufacturers began blending electronic and physical protocols to protect against theft. These key systems are known as transponder keys or chip keys, and are designed to make it harder for thieves to start the vehicle.
The key chips have unique serial codes which transmits a signal to the receiver in your car. When the signal is received it is compared to a code stored in the car's computer. If the codes match then your car will begin. If the codes aren't compatible, your car will not even start. This is one of the primary reasons why you should always keep a spare key in your car, especially if you have transponder-based systems.
You'll need special equipment to be able to program keys. auto key programmer 'll also need to purchase an uncut key for your specific make and model. You can buy them at the locksmith shop or at a car dealership, but it's important to purchase the correct keys. If you try to use a key that is from an alternative 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'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 observe whether the security light on your dashboard went out. If it didn't go out then you'll need to repeat the process three times.

If you want a more secure and reliable solution then you should visit a locksmith or dealer to have the vehicle programmed with an embedded chip. They will have the tools and equipment to access your car's onboard diagnostics port and then make the change.
Keyless Entry Systems
Keyless entry systems permit access to properties without the need for an actual credential. They make use of sensors in conjunction with an onboard computer for security. It is possible to control and monitor the system from any place within the property. Keys and locks are not required. The system can also detect and deactivate lost or stolen cards. In addition, the latest models are cloud-based and permit remote management and configuration.
Most modern cars are equipped with a keyless entry system. The system works by sending radio signals that are detected by the keyfob. The signals are compared to the code that is stored in the computer of the car and if everything is in order the car will start to unlock. If the signals do not match, the car will not start. There are several steps you can follow to program your new key fob, if it's not programmed yet.
You'll first need to make sure that all doors, except the driver's door are locked. You'll need the original key fob and any extras that you want to program. You can also try your local auto parts shop for the right tool to program your vehicle. If none of these methods work, you'll need to check the owner's manual, or a professional locksmith.
Once you have the right tool, follow the instructions of the manufacturer to begin changing the program of your key fob. This process is often relatively simple and quick. For instance, you could be directed to insert your new key into the ignition while keeping all doors closed and then press a button on the key fob within a brief time. The car might then respond by turning off the door locks or emitting a chime to indicate that the key has been successfully programmed.

Transponder Keys
Transponder keys, sometimes referred to as chip keys, are equipped with a microchip embedded in the head of the key. The antenna ring transmits electromagnetic energy to the transponder whenever the key is inserted into the ignition lock barrel. 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 unauthorised attempts to start the car since only right keys can be used.
This technology is believed to be more secure than conventional car keys because it makes it much harder for a thief to "hot wire" a vehicle and get it started. It's not foolproof, and thieves have found ways to evade detection and defeat the system. So even cars equipped with transponder key are not protected from theft.
Depending on the make and model of your vehicle, you may be able to program a new transponder key yourself using a key programmer that's compatible with your specific car. The key programmer comes 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.
