Prior to the beginning of the 21st century, most cars used basic key systems. The keys themselves were metal with grooves that corresponded to the internal components of the ignition cylinder. However, as time progressed and technology advanced as it did, automobile manufacturers began blending physical and electronic protocols to protect against theft. These key systems also known as transponder keys or chips keys are designed to make it more difficult for thieves to start the vehicle.
The key chips come with a unique serial code which transmits a signal to the receiver in your car. The signal is then compared to a code in the car's computer when it is received. If the codes match, your car will start. If the codes don't match, then your car will not even start. This is one of the primary reasons why you should always keep a spare key in your car, especially in the case of a transponder-based system.
You'll require specialized equipment to learn to program keys. You'll also need to purchase a blank key for your particular make and model. These can be purchased at the dealership or through a locksmith, but you must make sure that they are the right ones. If you use a key from another model, it won't work.
To begin the process, 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 around 10 minutes and 30 seconds. After the time has expired you can take off the key and see whether the security light on your dashboard was gone. If it didn't, you'll need repeat the process the third time.

Keyless Entry Systems

It is possible to monitor and control the system from any place within 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 as well as are cloud-based.
Modern automobiles are equipped with keyless entry systems. To accomplish this it emits radio signals which are picked up by a particular key fob. The signals are then compared with the correct code in the car's computer, and if everything is in order, the car will unlock. If the signals do not match then the car won't start. If your key fob has not been already programmed, it is possible to follow a series of steps to program it.

Transponder Keys

The energy is absorbed by the chip, which then transmits a radio frequency signal with an identification code that matches up to the unique digital serial number of the car's computer system. This prevents any attempts by anyone else to start the car, as only right keys can be used.
This technology is believed to be more secure than conventional car keys because it makes it much more difficult for thieves to "hot wire" an automobile and get it started. It's not foolproof, and thieves have found ways to evade detection and defeat the system. So even cars equipped with transponder key are not immune to theft.
Based on the make and model of your car, you may be able to program a new transponder by yourself with a key programer that is compatible with the car you own. The key programmer should come with a step-by-step guide that will walk you through the procedure of programming your key.

They will have the tools and equipment needed to cut a blank key, delete the old key from the computer of the car, and then program the new key for it to function correctly. This will save you time and money, and will keep your car's security system functioning as it should. It is also safer than making it yourself. Utilizing the wrong key programming software or following unofficial guidelines could alter the information stored in the car's system, and result in your new key not functioning.

Therefore, you'll need to have at least two working key fobs for your vehicle to be able to use the system. It is essential to have at least two spare keys on hand.
The key fobs contain electronic chips that transmit radio signals to the car's receiver. The car's computer then compares the key's code to the one in its database. If the codes match, the car will start. If not, the vehicle will be dead or refuses to start. Luckily, most of these electronic keys can be repaired and programmed by an experienced locksmith or an auto dealer using the appropriate equipment.
If you're able to find a cheap car key programmer on the internet or in an auto parts store, the process should be fairly straightforward.
