How to Program a Car Key

Some keys for cars can be preprogrammed by the owner himself, but it is best to speak with a professional. This will avoid any damage to the computer system of the vehicle and ensure that the key is working correctly.

How to program a Key

Most cars had basic mobile key programmer systems until the turn of 21st century. Keys were made from metal and incorporated grooves to correspond with the internal parts of the ignition cylinder. As time went on and technology advanced, more and more automobile manufacturers began to combine electronic and physical protocols to prevent theft. Key systems also known as transponder keys or chips keys are designed to make it difficult for thieves to open the vehicle.

The key chips come with an unique serial number that sends a message to the receiver inside your car. The signal is then compared to the computer of the car when it is received. If the codes match then your car will begin. If not, it will not start at all. This is the reason you should keep a spare car key, especially if your system is based on transponders.

You'll require specialized equipment to learn how to program keys. You'll also require a blank key for your particular make and model. You can purchase them from a locksmith or a car dealership, but it's important to purchase the correct keys. If you use a key that is for another model, it won't work.

If you want a more reliable and secure solution then you should visit an auto locksmith or dealer to have the car programmed with an embedded chip. They have the tools and equipment to connect to the onboard diagnostic port of your car and make the switch.

Keyless Entry Systems

Keyless entry systems permit access to property without the requirement of a physical credential. Security is provided by sensors that are combined with an onboard computing device.

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

Modern cars come with keyless entry systems. To accomplish this it emits radio signals which are picked up by a special key fob key programmer. The signals are then compared to the correct code in the car's computer and if everything is in order the car will start to unlock. The car won't start in the event that the signals are not identical. If your key fob has not been already programmed, it is possible to follow a series of steps to program it.

Transponder Keys

Transponder keys are also referred as chip keys. They have an embedded microchip in the head of keys. When the key is placed in the ignition lock barrel and turned to ON the antenna ring transmits an energy burst through the transponder chip. The chip absorbs this energy, and then transmits a radio frequency signal that includes an identification code. This code is in line with the unique serial numbers in the computer system of the car. This stops unauthorised attempts to start the car as only the right keys can be used.

It is believed that this technology will be more secure than traditional keys for cars because it makes it much more 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 aren't protected from theft.

Based on the make and model of your car You may be capable of programming a new transponder key by yourself using a key programmer that's compatible with the car you own. The key programmer will come with a manual that will guide you step-by-step through the process. Follow the instructions and turn on the security lights on your dashboard prior to beginning your engine.

If the codes match, the car will start. If not, the vehicle will not start or fail to start. Most electronic keys can be programmed and replaced by an experienced locksmith or auto dealer using the appropriate equipment.
