Up until the turn of the 21st century, the majority of cars utilized basic key systems. The keys themselves were metal with grooves that were connected to the internal components of the ignition cylinder. As technology improved, more and more car keys cutting and programming makers began to combine electronic and physical protocols to stop theft. These key systems, also known as transponder keys or chips keys, are designed to make it more difficult for thieves to start the vehicle.

When the signal is received, it compares it to an existing code in the car's computer. If the codes are similar, your car key programer near me will begin. If not, it won't start at all. This is the reason you should keep a spare car key, especially if your system is based on transponders.

The latest models also support remote management and configuration and are cloud-based.

The chip absorbs this energy, and then sends a radio frequency signal that contains an identification code. This code is in line with the unique digital serial numbers that are stored in the computer of the car. This is to prevent unauthorized attempts to begin the car, as only right keys can be used.

This type of technology is thought to be more secure than a traditional car key because it makes it more difficult for thieves to "hot wire" the vehicle and start it. It's not foolproof and thieves have found ways to evade detection and defeat the system. So even cars with transponder keys aren't safe from theft.

The key system is designed to stop hot-wiring (the practice of using the key of another vehicle to start the engine) and other similar methods. To make this process work you'll need at least two key fobs functioning for your vehicle. It is essential to have two spare keys available.

Key fobs are equipped with electronic chips that communicate with the car's receiver using radio signals. The computer in the car then compares the key's code with the one stored in its database. If the codes match, the car will start. If the codes don't match then the car will not start or remain dead. Luckily, most of these electronic keys can be programmed and replaced by a professional locksmith or an auto dealer using the appropriate equipment.
