How to Program a Key

Before the turn of the 21st century most cars used basic key systems. The keys were made of metal and had grooves to match the internal components of the ignition cylinder. As technology improved, more and more automobile manufacturers began to combine electronic and physical protocols to stop theft. Key systems like these are also referred to as transponder keys or chips keys are designed to make it difficult for thieves to steal a vehicle.

The key chips that are in the keys have a unique serial number, which transmits a signal to the receiver in your car. When the signal is received it compares it with an existing code in the car's computer. If the codes are similar then your car will begin. If the codes don't match, then your car won't even start. This is why it is important to keep an extra car key especially if the system is transponder-based.

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

Start by inserting the new key in the ignition and turning it to "on". You'll need to leave the key in this position for about 10 minutes and 30 seconds. Once the time has expired, you can remove your key and verify that the security indicator on your dashboard has gone out. If not then you'll have repeat the process a third time.

The most recent models also permit remote management and configuration, and are cloud-based.

Most modern cars come equipped with an entry system that is keyless. To make this work, the vehicle emits radio signals which are picked up by a special key fob. The signals are compared to the code stored in the computer of the car, and if all is well the car will be able to unlock. The car will not start if the signals are not the same. There are a variety of ways to program your new key fob, if it's not programmed yet.

You'll first need to make sure that all doors, except the driver's door are locked. You'll also need the original key fob, as well as any extras you'd like to program.

When the key is inserted into the barrel of the ignition lock, and turned into the ON position the antenna ring transmits an electromagnetic energy blast through the transponder chip. The chip absorbs this energy and then sends a radio frequency signal that includes an identification code. This code matches the unique serial numbers of the computer of the car. automotive key programming will prevent any unauthorized attempts to start the car since only the right key can perform the task.

The technology is believed to be more secure than the traditional car key since it makes it harder for a criminal to "hot wire" the vehicle and then start it. It's not foolproof and thieves have discovered ways to evade detection and defeat the system. So even cars with transponder keys aren't safe from theft.

This is one of the reasons why it's best to have at least one spare key in your possession.

The key fobs have electronic chips that transmit radio signals to the car's receiver. The computer compares the code of the key with the database. If the codes match the car starts. If the codes don't match then the car will not start or remain dead. The majority of these electronic keys can be programmed and replaced by an experienced locksmith or auto dealer using the appropriate equipment.

The process should be relatively simple if you can find a cheap key programmer on the internet or in an auto parts store.
