How to program a key
The majority of cars had basic key systems up until the turn of 21st century. The keys themselves were just metal with grooves that were connected to the internal parts of the ignition cylinder. However, as time progressed and technology advanced, more and more automobile manufacturers began to combine electronic and physical protocols to protect against theft. These key systems are known as transponder keys or chip keys, and they're designed to make it harder for thieves to start the vehicle.

The key chips in the keys have a specific serial number that sends an electronic signal to the receiver inside your car. The signal is compared with the computer of the car when it is received. If the codes are compatible, then the car will start. If not, it will not start at all. This is why it is important to keep a spare car key, especially if the system is transponder-based.
You'll require special equipment to be able to program keys. You'll need an uncut key that matches your car model and make. They can be purchased from a dealership or by a locksmith, but you must make sure they're the correct ones. If you try to use a key from an alternative model, it won't work.
To begin the process, insert the new key into the ignition and switch it to the "on" position. You will need to leave the new key in this position for around 10 minutes and 30 seconds. Once the time has expired you can take out your key and see if the security indicator on your dashboard has gone off. If not, you'll need repeat the process another time.
Be aware that this method will only work with GM vehicles, and it's still not completely secure. If you're looking for a more secure and reliable solution, then you should visit a professional locksmith or dealer to get your vehicle programmed with chip.

Keyless Entry Systems
Keyless entry systems provide property access without requiring the use of a physical ID. Security is provided by the combination of sensors and an onboard computing device. It is possible to control and monitor the system from anywhere in the property. Keys and locks are not required. The system can also detect lost or stolen cards and deactivate them. The most recent models also permit remote management and configuration, and are cloud-based.
Most modern cars are equipped with the keyless entry system. To make this work the car emits radio signals that are picked up by a particular key fob. The signals are compared with the code stored in the car's computer and, if all is in order the car will start to unlock. If the signals don't match, the car will not 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 to make sure that all doors are locked, except for the driver's side. You'll need to have the original key fob and any other devices you wish to program. You can also check your local auto parts shop to determine if they carry the right tool for your car. If these steps don't work, you'll have to consult your owner's manual or an expert locksmith.
Once you have the right tool, follow the manufacturer's instructions to begin changing the program of your key fob. This process is usually quick and simple. For instance, you may be asked to insert your new key into the ignition with the doors shut, and then press an appropriate button on the fob within a brief time period. The car might respond by reversing the door locks or emitting an audible sound as an indication that the key has been successfully programmed.
Many locksmiths have special tools that permit them to bypass the built-in EEPROM security of the car's key fob or remote.

It's best to have a professional handle this as they'll be able to minimize the risk of data corruption and also ensure that your keys are correctly programmed.
Transponder Keys
Transponder keys are also referred as chip keys. They are equipped with embedded microchips in the head of keys. The antenna ring transmits electromagnetic energy to the transponder whenever the key is placed in the barrel of the ignition lock. 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 system of the car. This helps prevent unauthorised attempts to start the car since only the right key will be able to start the car.
This type of technology is thought to be more secure than a traditional 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 defy the system - so that even vehicles that have transponder keys aren't immune from theft.
Based on the make and model of your vehicle, you may be able to program a new transponder key by yourself by using a key programming device that's compatible with your specific car. The key programmer comes with a user guide that walks you step-bystep through the procedure. Follow the directions and turn on the security light in your dashboard prior to beginning your engine.
You can seek out an expert locksmith to assist you if you're not confident with a key programmer or if you own a vehicle with more advanced features, such as remote head keys or intelligent keys. They will have the tools and equipment needed to cut an uncut key, erase the old key from the computer of the car, and program the new key to work correctly. This will save you money and time and ensure that your car's safety system working just as it should. Additionally, it's much safer than trying to do it yourself!
