How to Program a Car Key
Modern cars have more than a key that starts the engine. They also have a remote control that can lock or open doors. These key fobs need to be programmed in order to function properly.
Some keys for cars can be preprogrammed by the owner himself, but it is best to speak with an expert. This will help to protect against any possible damage to the car's computer system and ensure that the new key is working correctly.
How to program a Key
The majority of cars had basic keys systems up until the turn of 21st century. The keys were made of metal and incorporated grooves to match the internal components in the ignition cylinder. As time went on and technology improved, more and more car manufacturers began blending electronic and physical protocols to stop theft. These key systems are called transponder keys or chip keys, and they're designed to make it difficult for thieves to get into the vehicle.
The key chips in the keys have a specific serial number, which transmits a signal to the receiver inside of 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 your car will start. If the codes don't match, your vehicle won't start at all. This is why it is important to keep an extra car key especially if the system is based on transponders.
If you're looking to learn how to program keys, you'll require some specific equipment. You'll also need an uncut key for your specific model and make. You can purchase them from an auto locksmith or a locksmith dealership, but it's important to get the right ones. If you attempt to use a key that is from an alternative model, it will not work.
Begin by putting the new key into the ignition and turning it "on". You'll need to keep the new key in this position for around 10 minutes and 30 seconds. After the time is up you can take out your key and verify that the security indicator on your dashboard has gone out. If it didn't then you'll have to do it again for another time.
This method is only compatible with GM vehicles and it's not foolproof. If you're looking for a more secure and reliable solution go to a locksmith or a dealer to get your car programmed using an embedded chip. They have the tools and equipment needed to access the diagnostic port on your car's motherboard and then make the change.
Keyless Entry Systems
Keyless entry systems give access to properties without the need for the use of a physical ID. They utilize sensors in combination with an onboard computer to provide security. This lets you manage the system and monitor activities from anywhere within the property, and does away with the requirement for keys or locks. The system can also detect and block stolen or lost cards. 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 that are received by an specialized keyfob. The signals are compared with the code that is stored in the car's computer and, if all is in order the car will start to unlock. If the signals don't match and the car does not start. There are several ways to program your new key fob, if it's not programmed yet.
First, you'll need make sure that all 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. You can also visit your local auto parts store to determine if they carry the right tool for your vehicle.

The process is typically simple and quick. It is possible to be instructed to put the new key in the ignition when all doors are shut and then press the button on the keyfob within the time frame. The car might respond by cycling doors or emitting an audible sound as an indication that the key has been successfully programmed.

When the key is placed in the barrel of the ignition lock and turned to ON, the antenna ring sends an electromagnetic energy blast through the transponder chip. The chip absorbs this energy, and then sends a radio frequency signal that contains an identification code. The code is matched to the unique serial numbers in the computer of the car. This prevents unauthorized attempts to start the car, since only the right key can start the car.
It is believed that this technology will be more secure than traditional keys for cars because it makes it much harder for a thief to "hot wire" a vehicle and get it started. It's not foolproof and thieves have found ways to evade detection and defeat the system. So even cars with transponder key are not immune to theft.
Depending on the make and model of your vehicle You may be able to program a new transponder by yourself by using a key programming device that's compatible with your specific car.

If the codes match, the car will start. If the codes don't match, the car will not start or remain dead. Most electronic keys can be programmed and replaced by an expert locksmith or auto dealer using the proper equipment.
