How to Program a Car Key

How to program the key

Most cars had basic key systems prior to the turn of the 21st century. Keys themselves were metal with grooves that were connected to the internal components of the ignition cylinder. As time passed and technology advanced, more and more automobile manufacturers began blending electronic and physical protocols to stop theft. Key systems are also referred to as transponder keys or chips keys are designed to make it harder for thieves to steal a vehicle.

The key chips that are in the keys have a specific serial number, which transmits an electronic signal to the receiver inside your car. The signal is then compared to the car’s computer when it is received. If the codes match then your car will begin. If not, it won’t start at all. This is one of the main reasons you should keep a spare key on your vehicle, especially if you have transponder-based systems.

You’ll require special equipment to be able to program keys. You’ll also require a blank key for your specific model and make. You can buy them at an auto locksmith or a locksmith dealership, but it’s important to buy the right one. If you use a key for another model, it will not function.

To begin the process, insert the new key into the ignition and turn it to the “on” position. It is necessary to leave the new key in this position for approximately 10 minutes and 30 second. Once the time is up you can take out the key and see if the security light on your dashboard was gone. If it did not then you’ll need to repeat the process for the third time.

This method is only compatible with GM vehicles, and isn’t foolproof. If you want a more reliable and secure solution then you should visit a locksmith or dealer to have your vehicle programmed with an embedded chip. They are equipped with the tools and equipment required to access the onboard diagnostics port of your car and make the change.

Keyless Entry Systems

Keyless entry systems provide access to properties without the need for a physical credential. Security is provided by the combination of sensors and an onboard computing device.

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

Modern cars are equipped with keyless entry systems. The system works by emitting radio signals which are received by a special keyfob. The signals are compared to the code stored in the computer of the car, and if all is well, the car will unlock. If the signals don’t match then the car won’t start. If your key fob isn’t already programmed, you can follow several steps to program it.

Transponder Keys

Transponder keys, sometimes referred to as chip keys, have an embedded microchip in the head of the key. The antenna ring transmits electromagnetic energy to the transponder whenever the key is placed into the ignition lock barrel. The energy is absorbed by the chip, which then transmits an audio frequency signal that contains an identification code that corresponds up to the unique digital serial number of the car’s computer system. This will prevent any unauthorised attempts to start the car as only the correct key can perform the task.

The technology is believed to be more secure than conventional car keys because it makes it much difficult for thieves to “hot wire” a vehicle and start it. However, it’s not foolproof and thieves have discovered ways to evade and defy the system – which means that even cars equipped that have transponder keys aren’t protected from theft.
