How to Program a Car Key
Modern cars use more than just a key to start the engine, they also have a remote that can lock and unlock doors. These key fobs must be programmed to work.
It is possible to program some car keys by the owner, but it is best to consult a professional. This will help to protect against any possible damage to the car's computer system and ensure that the new key functions correctly.
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 incorporated grooves to match the internal components in the ignition cylinder. As technology advanced, more and more automobile makers began to mix physical and electronic protocols to avoid theft. Key systems also known as transponder keys or chips keys, are designed to make it more difficult for thieves to steal the vehicle.
The key chips contain an unique serial number which transmits a signal to the receiver inside your car. When the signal is received, it compares it to the code that is stored in the car's computer. If the codes match, then the car will start. If the codes aren't compatible, your vehicle won't start at all. This is one of the main reasons you should keep a spare key on your vehicle, especially when you use a transponder-based system.
If you want to learn how to program a key, you'll need some special equipment. You'll also need to purchase a blank key that matches your specific make and model. They can be bought at a dealership or by locksmiths, but you must make sure they're the right ones. If you try to use a key that is from an alternative model, it won't work.
To start the process, you need to insert the new key into the ignition and turn it to the "on" position. You'll need to keep the key in this position for about 10 minutes and 30 seconds. Once the time is up, you can remove the key and see whether the security light on your dashboard was gone. If it didn't, you will need to do it a third time.

If you want a more secure and reliable solution then you should visit a locksmith or a dealer to have your car programmed with an embedded chip. These professionals have the tools and equipment required to connect to the onboard diagnostic port on your car and make the necessary changes.
Keyless Entry Systems
Keyless entry systems grant access to property without the requirement for a physical ID. Security is achieved through a combination between sensors and an onboard computer. This allows you to control the system and monitor activity from anywhere within the property, and eliminates the need for keys or locks. The system is also able to detect stolen or lost cards and then deactivate them. In addition, the newest models are cloud-based, allowing for remote management and configuration.
Most modern cars are equipped with an entry system that is keyless. To accomplish this it emits radio signals which are picked up by a particular key fob. These signals are then compared with the correct code that is 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, you may follow a few steps to program it.
First, you'll need to ensure all the doors are locked, except for the driver's side. Also, you'll need the original key fob as well as any extras you want to program.

This is a risky technique and could cause data corruption in your car's computer. It is best to let an expert handle this task because they will be able to reduce the chance of data corruption and make sure that your keys are correctly programmed.
Transponder Keys
Transponder keys, also referred to as chip keys, have a microchip built into the head of the key. The antenna ring transmits electromagnetic energy to the transponder when the key is placed in the barrel of the ignition lock. The chip absorbs the energy and then transmits a radio frequency signal that contains an identification code. This code is in line with the unique serial numbers of the computer of the car. This is to prevent unauthorised attempts to start the car since only right keys can be used.
The technology is believed to be more secure than the traditional car key since it makes it harder for a thief "hot wire" the vehicle and start it. However, it's not foolproof and thieves have discovered ways to trick and defeat the system - so that even vehicles with transponder keys aren't immune from theft.

Therefore, you'll require at minimum two working key fobs for your vehicle in order to be able to use the system. This is just one of the reasons why it's recommended to have at least one spare key in your possession.
Key fobs are equipped with electronic chips that communicate with the car's receiver via radio signals. The car's computer then compares the code on the key to the one stored in its database. If the codes match the car will be able to start. If the codes do not match, the car will not start or remain dead. Most of these electronic key can be programmed and replaced by a professional locksmith or dealer in the field with the appropriate equipment.
