How to Program a Car Key
Modern cars use more than just a key to start the engine, they also come with a remote that can lock and unlock doors. Key fobs have to be programmed in order to function properly.
Some car keys can be preprogrammed by the owner, however it's best to consult with a professional. This will help prevent any possible damage to the car's computer system and also ensure that the new key functions correctly.
How to Program a Key
Before the turn of the 21st century the majority of cars had basic key systems. The keys were made of metal and had grooves to match the internal components in the ignition cylinder. As technology improved the number of car makers began to combine electronic and physical protocols in order to prevent theft. These key systems, also known as transponder keys or chips keys, are designed to make it more difficult for thieves to steal a vehicle.
The key chips come with unique serial codes that transmits a message to the receiver inside 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 will not even start. This is why it is important to keep a spare car key, especially if the system is based on transponders.
You'll need special equipment to learn to program keys. You'll also need to purchase an uncut key that matches your specific model and make. You can purchase these at an auto locksmith or a locksmith dealership, but it's essential to buy the right one. If you use a key for another model, it will not work.
Start the process by inserting the new key into the ignition and turning it to "on". It is necessary to keep the key in this position for around 10 minutes and 30 seconds. Once the time is up, you can remove the key and see if the security light on your dashboard went out. If it didn't go out you'll have to do it three times.
Remember that this method will only work on GM vehicles but it's not 100% secure. If you're looking for a more reliable and secure solution, you can visit a locksmith or a dealer to have the car programmed with an embedded chip. They will have the tools and equipment to connect to the onboard diagnostic port of your car and then make the change.
Keyless Entry Systems
Keyless entry systems allow access to properties without the requirement for an actual credential. They utilize a combination of sensors and an onboard computer for security. It is possible to monitor and control the system from anywhere within the property. Keys and locks are not required. The system can also detect stolen or lost cards and disable 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 accomplish this, the vehicle emits radio signals which are picked up by a specific key fob. These signals are then compared with the correct code that is stored in the car's computer and when everything is in order, the car will unlock. The car won't start when the signals aren't the same. There are a variety of steps you can take to program your new key fob, if it's not already programmed.
First, you'll need to make sure that all doors excluding the driver's door are locked. Also, you'll need the original key fob as well as any extras you'd like to program. You can also check the local auto parts store to see if they've got the right tool for your vehicle. If none of these methods work, you'll have to consult the owner's manual or an expert locksmith.

For instance, you could be instructed to insert your new key into the ignition while keeping the doors shut, and then press the button on the key fob within a very short time. The car could then respond by turning off the door locks or emitting a chime to signal that the key has been successfully programmed.
Many locksmiths are equipped with special tools that allow them to bypass the built-in EEPROM security of your car's key fob or remote.

It is recommended to have an expert handle this task, as they will be able to reduce the chance of data corruption and make sure that your keys are programmed correctly.
Transponder Keys
Transponder keys are also referred to as chip keys. They have an embedded microchip in the head of keys. The antenna ring transmits electromagnetic energy to the transponder when the key is placed into the ignition lock barrel. This energy is absorbed into the chip and sends back the radio frequency signal, which includes an identification code that matches up to the unique digital serial number of the car's computer system. This will prevent any unauthorized attempts to start the car because only a valid key will be able to do so.
This technology is thought to be more secure than a conventional car key because it makes it difficult for thieves to "hot wire" the vehicle and start it. But it's not foolproof, and thieves have found ways to trick and defeat the system - which means that even cars equipped that have transponder keys aren't safe from theft.
Depending on the brand and model of your vehicle depending on the make and model of your car, you might be able to program a new transponder by yourself using a key programmer that's compatible with the car you own. The key programmer will come with a user guide that walks you step-bystep through the procedure. Follow the directions and turn on the security lights on your dashboard prior to starting your engine.
You can ask a professional locksmith to help you if you're not sure about using the key programmer or you own a vehicle with more advanced features, such as remote head keys or intelligent keys. They'll have the right tools and equipment to cut the blank key, remove your old one from your computer in the car and then program the new one so that it will work properly. This will save you time and money, and keep your car's safety system operating exactly as it should. It is also safer than making it yourself. Making use of the wrong key programmers or following unofficial guidelines could alter the information stored in the vehicle's system and result in the key not functioning.

This is one of the main reasons why it's a good idea to always have at least one spare key in your possession.
The keys have electronic chips inside them that communicate with the car's receiver via radio signals. The computer compares the key's code with the database. If the codes match the car starts.
