How to program a Key
Before the turn of the 21st century the majority of cars had basic key systems. Keys themselves were metal and featured grooves that matched the internal parts of the ignition cylinder. As time went on and technology advanced as it did, automobile manufacturers began blending electronic and physical protocols to stop theft. These key systems are also referred to as transponder keys or chips keys are designed to make it more difficult for thieves to steal the vehicle.
The key chips have unique serial codes that sends a message to the receiver in your car. The signal is compared with a code in the computer of the car when it is received. If the codes are identical, your car will begin. If not, it won't start at all. This is the reason you should keep an extra car key, especially if your system is transponder-based.
You'll require special equipment to be able to program keys. You'll also need a blank key for your particular make and model. These can be purchased at a dealership or by a locksmith, but you must make sure that they are the right ones. If you use a key for another model, it won't function.
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 leave the key in this position for approximately 10 minutes and 30 seconds. After the time has expired, you can remove the key and see if the security light on your dashboard was gone. If it didn't go out, you will need to do it a third time.

If you're looking for a more reliable and secure solution go to a locksmith or dealer to have the vehicle programmed with an embedded chip. These professionals have the tools and equipment required to connect to the diagnostic port on your car and make the change.
Keyless Entry Systems
Keyless entry systems permit access to properties without the requirement for an actual credential. Security is provided by sensors that are combined with an onboard computer. It 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 lost or stolen cards and disable them. The latest models also support remote management and configuration and are cloud-based.
The majority of modern cars are equipped with an entry system that is keyless. To enable this feature, the vehicle emits radio signals that are picked up by a specific key fob. The signals are compared with the code stored in the car's computer and, if all is in order, the car will unlock. If the signals don't match then the car won't start. There are a variety of steps you can follow 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. You'll also need the original key fob, along with any additional keys you'd like to program.

If none of these methods work, you'll have to go through the owner's manual or a professional locksmith.
Once you have the right tool You can begin the changing the programming of your key fob by following the instructions of the manufacturer. This procedure is usually quick and easy. For instance, you could be instructed to insert your new key into the ignition while keeping all doors shut and then press an appropriate button on the fob within a brief time. The car could then respond by cycling the door locks or generating a chime to signal that the key has been successfully programmed.
A lot of locksmiths have tools that let them bypass the built-in EEPROM security in the car's key fob or remote. This is a risky technique and can corrupt the data stored in the car's computer. This should be left to a professional who can lower the chance of data corrupting and ensure that your keys are programmed correctly.
Transponder Keys
Transponder keys are also referred to as chip keys. They are equipped with an embedded microchip in the head of keys. The antenna ring transmits electromagnetic energy to the transponder whenever the key is inserted into the ignition lock barrel. The chip absorbs the energy and then transmits a radiofrequency signal which contains an identification number. This code is in line with the unique serial numbers in the car's computers. This helps prevent unauthorised attempts to start the car because only a valid key can perform the task.
The technology is believed to be more secure than the traditional car key since it makes it difficult for a criminal to "hot wire" the vehicle to start it. It's not foolproof, and thieves have discovered ways to evade detection and defeat the system. Therefore, even vehicles with a transponder keys aren't protected from theft.
Depending on the make and model of your vehicle, you may be in a position to program a brand new transponder key yourself by using a key programming device that's compatible with your particular car. The key programmer should include an easy-to-follow guide to walk you through the process of programming your key. Follow the steps and switch on the security lights on your dashboard before you start your engine.
You can contact a professional locksmith to help you if you're not sure about using the key programmer or you have a car with more advanced features, such as remote head keys or intelligent keys. They'll have the appropriate tools and equipment to cut your blank key, erase your old one from your computer in your car, and then program the new key so that it will work properly. This will save your time and money, and will keep your car's security system operating just as it should. Additionally, it's much more secure than doing it yourself! Making use of the wrong key programmers or following unofficial guidelines could cause a problem with the information stored in your car's system, and result in the new key not working.
Remotes
It is possible to change the programming of your car keys if they're not working. This is a straightforward process for many modern cars that utilize key fobs. However, certain models are more complex and need to be programmed using an instrument that is available from a dealer or auto locksmith.
Fortunately, most modern car manufacturers have made their key systems more secure to prevent theft of vehicles. The key system was designed to prevent hot-wiring (the method of using the key of another vehicle to start the engine) and other similar methods. To be able to make this process work, you will need at least two key fobs working for your vehicle. It's essential to have at minimum two spare keys available.
Key fobs are equipped with electronic chips that communicate via radio signals to the car's receiver. The computer compares the key's code with the database. If the codes match the car will be able to start. If the codes do not match then the car will not start or remain dead. Most electronic keys can be programmed and replaced by an experienced locksmith or auto dealer with the right equipment.
If you're able to find a low-cost car key programer on the internet or in an auto parts store, the procedure will be relatively simple. You'll need to follow a set-up which include inserting the ignition key and turning it on, without starting the vehicle, then shutting off the key. You'll have to repeat this a certain number of times within a specific time frame for your vehicle to enter programming mode. The door locks will turn on and off or a chime will sound.
Certain modern vehicles can only be programmed by means of a device that is connected to the onboard diagnostics port, or an EEPROM programing procedure. The majority of these tools are costly and therefore are not accessible to the majority of car owners. Many experts in the field recommend consulting a reputable auto dealership or locksmith to program your keys.
