How to Program a Car Key
Modern cars use more than a key to start the engine. They also come with a remote that can lock and unlock doors. Key fobs must be programmed to work properly.
Certain keys for cars can be programmed by the owner himself, but it is recommended to consult an expert. This will protect against any possible damage to the computer system and ensure that the new key works correctly.
How do you program a key?
Before the turn of the 21st century the majority of cars had basic key systems. The keys themselves were just metal and had grooves that corresponded to the internal components of the ignition cylinder. As technology improved, more and more car makers began to mix physical and electronic 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 start the vehicle.
The key chips contain an unique serial number which transmits a signal to the receiver in your car. The signal is compared with the car's computer when it is received. If the codes match, the car will start. If not, it will not start at all. This is the reason you should keep an extra car key especially if your system is based on transponders.
You'll require specialized equipment to learn how to program keys. You'll need a blank key that matches the car's model and make. You can purchase these at the locksmith shop or at a car dealership, but it's important to purchase the correct keys. If you try to use a key from an alternative model, it will not work.
To begin the process, insert the new key into the ignition and turn it to the "on" position. It is necessary to leave the new key in this position for approximately 10 minutes and 30 seconds. After the time is up you can take off your key and see if the security indicator on your dashboard has gone out. If not then you'll need repeat the process a third time.
This method is only compatible with GM vehicles and it's not foolproof. If you're looking for a reliable and secure solution then you should visit an auto locksmith or dealer to get your car programmed using an embedded chip. They are equipped with the tools and equipment required to connect to the diagnostic port on your car and perform the change.
Keyless Entry Systems
Keyless entry systems allow 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. car key programming is possible to manage and monitor the system from anywhere within the property. Keys and locks are not required. The system is also able to detect and deactivate lost or stolen cards. The latest models also support remote management and configuration as well as are cloud-based.
Modern automobiles are equipped with keyless entry systems. The system works by sending radio signals which are received by an specialized keyfob. These signals are then compared to the correct code that is stored in the car's system, and when everything is in order the car will start to unlock. The car will not start if the signals are not the same. If your key fob has not been already programmed, you can follow a few steps to program it.
You'll first need to make sure that all doors, except the driver's door are locked. You'll need the original key fob as well as any additional devices you want to program.

Transponder Keys
Transponder keys, sometimes referred to as chip keys, are equipped with an embedded microchip in the head of the key. The antenna ring transmits electromagnetic energy to the transponder when the key is inserted in the barrel of the ignition lock. The chip absorbs the energy and then transmits a radio frequency signal which contains an identification number. The code is matched to the unique digital serial numbers in the computer of the car. This prevents unauthorised attempts to start the car because only a valid key can do so.
This technology is thought to be more secure than a conventional car key since it makes it more difficult for thieves to "hot wire" the vehicle and then start it. But it's not foolproof and thieves have discovered ways to trick and thwart the system so that even vehicles with transponder keys aren't immune from theft.
You might be able to program a transponder key on your own if you have an instrument that works with your car. The key programmer should include an easy-to-follow guide to walk you through the process of programming your key. Once you have your key and key programmer, follow the steps carefully and ensure that the security light on your dashboard is turned ON prior to turning the engine ON.

The key fobs have electronic chips in them that communicate with the car's receiver via radio signals. The computer in the car then compares the code on the key to the one in its database. If the codes match the car starts. 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 an experienced locksmith or auto dealer using the proper equipment.
