Before the turn of the 21st century most cars used basic key systems. The keys themselves were metal and featured grooves that matched the internal parts of the ignition cylinder. As technology advanced, more and more car makers began to combine physical and electronic protocols in order to prevent theft. These key systems are known as transponder keys or chip keys, and they're designed to make it harder for thieves to open the vehicle.

The key chips inside the keys have a unique serial number that transmits signals to the receiver inside your car. When the signal is received, it compares it to an existing code in the car's computer. If the codes match the car will begin to begin to start. If the codes aren't compatible, your car won't even start. This is one of the primary reasons why you should always keep a spare key on your vehicle, particularly in the case of a transponder-based system.

You'll need special equipment to learn to program keys. You'll need to buy a blank key that matches your reprogramme car key model and make. You can buy them at an auto locksmith or a locksmith dealership, but it's important to get the right ones. If you use a key from another model, it will not work.

To begin the process, simply insert the new key into the ignition and switch it to the "on" position. You'll need to keep the new key in this position for around 10 minutes and 30 second. After the time is up you can take out your key and see if the security indicator on your dashboard has gone off. If it didn't then you'll need to do it a third time.

The system can also detect and deactivate lost or stolen cards. Additionally, the most recent models are cloud-based, allowing for remote management and configuration.

Modern cars come with keyless entry systems. The system works by emitting radio signals that are received by the keyfob. The signals are compared with the code that is stored in the computer of the car and, if all is well the car will start to unlock. The car won't start when the signals aren't identical. There are a variety of steps you can take to program your new key fob, if it isn't already programmed.

Transponder Keys

When the key is inserted into 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. This energy is absorbed by the chip and it transmits a radio frequency signal with an identification code that is matched with the unique serial number that is stored in the car's computer system. This is to prevent unauthorised attempts to start the car since only correct keys will be able.

This technology is believed to be more secure than traditional car keys because it makes it difficult for thieves to "hot wire" an automobile and start it. But it's not foolproof, and thieves have found ways to evade and defeat the system - which means that even cars equipped with transponder keys are not protected from theft.

Based on the make and model of your car, you may be in a position to program a brand new transponder key by yourself using a key programmer that's compatible with your particular car.
