How to Program a Car Key
Modern cars have more than a key to start the engine, they also have a remote that can lock and unlock doors. These key fobs need to be programmed correctly.
It is possible to pre-program certain keys for cars by the owner, however it is best to consult a professional. This will help to protect against any possible damage to the computer system and also ensure that the new key is working correctly.
How do you program a key?
Most cars had basic key systems prior to the turn of the 21st century. The keys were made of metal and featured grooves that correspond with the internal parts in the ignition cylinder. As time passed and technology improved, more and more automobile manufacturers began blending electronic and physical protocols to prevent theft. These key systems are called transponder keys or chip keys and are designed to make it more difficult for thieves to get into the vehicle.
The key chips come with a unique serial code that transmits a message to the receiver inside your car. The signal is compared to a code in the computer of the car when it is received. If the codes are identical, 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 on your vehicle, especially when you use transponder-based systems.
If you want to learn how to program a key, you'll need some special equipment. You'll need a blank key that matches the model and make of your car. You can purchase these at an auto locksmith or a locksmith dealership, but it's crucial to get the right ones. If you use a key that is for another model, it won't work.
To start the process, you need to insert the new key into the ignition and switch 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 is up you can take off your key and verify that the security indicator on your dashboard has gone out. If not, you'll need to repeat the process for the third time.
Be aware that this method can only work with GM vehicles however it isn't 100% secure. If you're looking for a more secure and reliable option, you should consult a professional locksmith or the dealer to have your car programmed with chip. They are equipped with the tools and equipment required to connect to the diagnostics port of your car and make the switch.
Keyless Entry Systems
Keyless entry systems allow access to your property without the need for a physical credential. Security is offered by a combination between sensors and an onboard computer. It is possible to monitor and control the system from anywhere in the property. Keys and locks are not required. The system can also detect and disable stolen or lost cards. The latest models also support remote management and configuration and are cloud-based.
The majority of modern cars are equipped with a 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 to the code stored in the computer of the car, and if all is in order, the car will unlock. If programmed car keys do not match and the car does not start. If your key fob is not already programmed, you may follow a few steps to program it.
First, you'll need make sure that all doors are locked, with the exception of the driver's side. You'll need to have the original key fob along with any other devices you wish to program. You could also check with your local auto parts store for the right programming tool for your car. If these steps don't work, you'll have to consult your owner's manual or a professional locksmith.

You may be instructed to insert the new key into the ignition after closing all doors, and then press the button on the keyfob within a certain time period. The car may respond by turning off the doors or emitting an audible chime as a sign that the key has been successfully programmed.
Many locksmiths have special tools that let them bypass the built-in EEPROM security of the key fob of your car or remote. This is a dangerous method and could cause data corruption in your car's computer. It is best to let an expert handle this as they'll be able to reduce the chance of data corruption and make sure that your keys are correctly programmed.
Transponder Keys
Transponder keys are also referred to as chip key. They have a microchip embedded in the head of the keys. When the key is inserted into the ignition lock barrel and turned to ON, the antenna ring sends an electromagnetic energy blast through the transponder chip. This energy is absorbed into the chip, which then transmits an audio frequency signal that contains an identification code that is matched up to the unique serial number of the car's computer system. This helps prevent unauthorised attempts to start the car, as only the correct key can perform the task.
This technology is thought to be more secure than a traditional car key because it makes it more difficult for a criminal to "hot wire" the vehicle and then start it. But it's not foolproof and thieves have found ways to evade and thwart the system so that even cars with transponder keys aren't safe from theft.
You might be able to program a transponder key on your own when you have a key programmer compatible with your vehicle. The key programmer comes with a manual that will take you step-by-step through the procedure. Once you have the key and key programmer, follow the steps carefully and ensure the security light on your dashboard is ON prior to turning the engine on.
You can contact a professional locksmith to help you if you are not confident with the key programmer or you own a vehicle 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, delete your previous one from the computer in your car and then program the new one so that it works correctly. This will save you time and money, and will help keep your car's security system functioning just as it should. Plus, it is much safer than making it yourself. Using the wrong key programmers or following unofficial guides can cause a problem with the information stored in your vehicle's system and result in the key not working.
Remotes

To ensure that this method works, you will need at least two key fobs working for your vehicle. This is one of the reasons why it's best to have at least one spare key available.
The key fobs have electronic chips that communicate using radio signals with the car's receiver. The computer compares the code of the key with the database. If the codes match, the car will start. If the codes do not match then the car will not start or will remain dead. Luckily, most of these electronic keys can be repaired and programmed by a professional auto dealer or a locksmith with the right equipment.
The process should be relatively simple if you are able to find a low-cost key programmer on the internet or in an auto parts store.
