How to Program a Car Key

Some car keys can be preprogrammed by the owner themselves but it's best to consult with a professional. This will help to avoid any damage to the car's computer system and ensure that the new key works properly.

How to Program a Key

The majority of cars had basic keys systems until the turn of the 21st century. Keys were made from metal and had grooves to correspond with the internal parts in the ignition cylinder. As technology improved, more and more automobile manufacturers began to combine electronic and physical protocols to stop theft. These key systems are called transponder keys or chip keys and are designed to make it more difficult for thieves to get into the vehicle.

The key chips contain an unique serial number that transmits a message 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 are similar, your car will begin to start. If the codes don't match, then your car won't even start. This is one of the primary reasons why you should always keep a spare key in your vehicle, especially when you use a transponder-based system.

You'll need special equipment to learn how to program keys. You'll need a blank key that is compatible with the model and make of your car.

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

Modern automobiles are equipped with keyless entry systems. To make this work it emits radio signals that are picked up by a specific key fob. The signals are then compared to the code stored in the car's computer and if everything is in order, the car will unlock. If the signals do not match and the car does not start. If your key fob has not been already programmed, it is possible to follow a series of steps to program it.

The chip absorbs the energy and then sends a radio frequency signal which contains an identification number. This code is in line with the unique serial numbers of the computer system of the car. This prevents unauthorized attempts to start the car because only a valid key can start the car.

This technology is thought to be more secure than a conventional car key because it makes it more difficult for thieves to "hot wire" the vehicle and then start it. But it's not foolproof, and thieves have found ways to trick and defy the system - so that even vehicles that have transponder keys aren't immune from theft.
