Before the turn of the 21st century most cars used basic key systems. Keys were made from metal and had grooves to correspond with the internal parts of the ignition cylinder. As technology advanced, more and more car makers began to mix electronic and physical protocols to stop theft. Key systems like these, also known as transponder keys or chips keys, are designed to make it difficult for thieves to steal an automobile.

The key chips have an unique serial number that transmits a message to the receiver in your car. When the signal is received, it compares it to a code stored in the car's computer. If the codes match, your car will start. If not, it won't start at all. This is one of the main reasons to keep a spare key on your vehicle, particularly in the case of an electronic transponder.

You'll require specialized equipment to learn how to program keys. You'll need to buy a blank key that matches the car's model and make. You can purchase them from an auto locksmith or a locksmith dealership, but it's important to buy the right one. If you use a key from another model, it won't function.

Start by inserting the new key into the ignition and turning it to "on". You'll need to keep the key in this position for around 10 minutes and 30 seconds.

The most recent models also permit remote management and configuration as well as are cloud-based.

Modern cars come with keyless entry systems. To make this work, the vehicle emits radio signals that are detected by a particular key fob. The signals are then compared against the correct code stored in the car's computer and if everything is in order the car will start to unlock. If the signals don't match, the car will not start. If your key fob isn't already programmed, it is possible to follow a series of steps to programme it.

The first step is to make sure that all doors are locked except for the driver's side. You'll need the original key fob along with any additional devices you want to program.

The energy is absorbed by the chip and sends back an audio frequency signal that contains an identification code that is matched up to the unique digital serial number that is stored in the car's computer system. This is to prevent any attempts by anyone else to start the car, as only correct keys will be able.

The technology is believed to be more secure than a traditional car key, as it makes it difficult for a thief "hot wire" the vehicle to start it. However, it's not foolproof and thieves have discovered ways to deceive and defy the system - which means that even cars equipped with transponder keys aren't safe from theft.

Depending on the make and model of your car depending on the make and model of your car, you might be capable of programming a new transponder key yourself by using a key programming device that's compatible with your particular car.
