How to Program a Key
Most cars had basic key systems until the turn of the 21st century. Keys themselves were metal and featured grooves that were connected to the internal components of the ignition cylinder. As technology improved, more and more car makers began to combine physical and electronic protocols to stop theft. These key systems, also known as transponder keys or chips keys, are designed to make it more difficult for thieves to start an automobile.
The key chips contain an unique serial number that sends a message to the receiver in your car. When the signal is received it is compared to the code that is stored in the car's computer. If the codes match, then the car will start. If the codes don't match, then your car won't even start. This is one of the primary reasons you should keep a spare key for your car, especially when you use an electronic transponder.
You'll require specialized equipment to learn how to program keys. You'll need an uncut key that matches the car's model and make. They can be purchased from a dealership or by locksmiths, but you must make sure they're the correct ones. If you use a key from another model, it will not function.
Start by inserting the new key into the ignition and turning it to "on". It is necessary to leave the new key in this position for about 10 minutes and 30 second. After the time has expired you can take out the key and see whether the security indicator on your dashboard went out. If it didn't then you'll have to repeat the process for the third time.
Be aware that this method will only work on GM vehicles but it's not completely secure. If you want a more secure and reliable solution, you can visit a locksmith or dealer to have the car programmed with an embedded chip.

Keyless Entry Systems

The system can also detect and deactivate lost or stolen cards. The newest models also allow remote management and configuration, and are cloud-based.
The majority of modern cars are equipped with the keyless entry system. To make this work the car emits radio signals that are detected by a specific key fob. These signals are then compared against the correct code stored in the car's computer and when everything is in order the car will start to unlock. If the signals do not match, the car will not start. There are several 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, with the exception of the driver's side. You'll also require the original key fob, as well as any extras you want to program.

This is best left to a professional who can reduce the risk of data corruption and make sure that your keys are properly programmed.
Transponder Keys
Transponder keys, also known as chip keys, come with a microchip embedded in the head of the key. When the key is inserted into the barrel of the ignition lock, and then turned into the ON position the antenna ring emits a burst of electromagnetic energy through the transponder chip. The chip absorbs the energy and then transmits a radio frequency signal that contains an identification code. This code matches the unique serial numbers of the computer system of the car. This will prevent any unauthorized attempts to start the car, because only a valid key can do so.
It is believed that this technology will be more secure than traditional keys for cars because it makes it difficult for thieves to "hot wire" an automobile and get it started. But it's not foolproof and thieves have discovered ways to deceive and defeat the system - which means that even cars equipped that have transponder keys aren't immune from theft.
Depending on the make and model of your car You may be in a position to program a brand new transponder key by yourself by using a key programming device that's compatible with your specific car. The key programmer should include a step-by-step guide that will walk you through the procedure of programming your key. Follow the directions and switch on the security lights on your dashboard prior to beginning your engine.
