How do you program the key
Prior to the beginning of the 21st century most cars used basic key systems. Keys were made of metal and had grooves to correspond to the internal parts of the ignition cylinder. However, as time progressed and technology advanced and improved, automobile manufacturers began blending physical and electronic protocols to protect against theft. Key systems also known as transponder keys or chips keys are designed to make it difficult for thieves to open a vehicle.
The key chips in the keys have a unique serial number that transmits signals to the receiver inside your car. When the signal is received it is compared to an existing code in the car's computer. If the codes match, the car will start. If not, it won't start at all. This is why you should keep a spare car key, particularly if your system is based on transponders.
You'll need special equipment to learn to program keys. You'll need a blank key that matches the model and make of your car. They can be bought at the dealership or through locksmiths however, you must be sure they're the correct ones. If you use a key for another model, it will not work.

After the time is up you can take out your key and check if the security indicator on your dashboard has gone off. If it didn't go out you'll have to repeat the process a third time.
Remember that this method can only work with GM vehicles however it isn't 100% secure. If you want a more reliable and secure solution then you should visit a locksmith or dealer to have the vehicle programmed with an embedded chip.

The most recent models also permit remote management and configuration, and are cloud-based.
Modern cars are equipped with keyless entry systems. The system works by sending radio signals that are detected by a special keyfob. The signals are then compared against the correct code in the car's computer and if everything is in order the car will start to unlock. If the signals do not match and the car does not start. There are a variety of steps you can take to program your new key fob, if it's not already programmed.

This energy is absorbed by the chip, which then transmits a radio frequency signal with an identification code that matches up to the unique digital serial number of the car's computer system. This will prevent any unauthorised attempts to start the car, because only a valid key can perform the task.
This technology is believed to be more secure than conventional car keys because it makes it much more difficult for thieves to "hot wire" the vehicle and get it started. It's not foolproof and thieves have found ways to evade detection and defeat the system. So even cars with transponder key are not safe from theft.

This will save you money and time and will keep your car's safety system operating just as it should. Additionally, it's much safer than trying to do it yourself!
