How to Program a Car Key
Modern cars use more than just a key to start the engine. They also include a remote to lock and unlock doors. These key fobs need to be programmed correctly.
Certain keys for cars can be programmed by the owner himself, but it's best to consult with a professional. This will avoid any damage to the computer system of the vehicle and ensure that the key works properly.
How to program the key
The majority of cars had basic keys systems prior to the turn of the 21st century. The keys themselves were metal and had grooves that matched the internal parts of the ignition cylinder. As time went on and technology improved as it did, automobile manufacturers began blending electronic and physical protocols to protect against theft. Key systems like these, also known as transponder keys or chips keys, are designed to make it difficult for thieves to open the vehicle.
The key chips that are in the keys have a unique serial number that transmits signals to the receiver inside your car. When the signal is received it compares it with an existing code in the car's computer. If the codes are identical then your car will start. If the codes don't match, then your car won't even start. This is one of the primary reasons why you should always keep a spare key in your vehicle, especially when you use a transponder-based system.
You'll require special equipment to learn how to program keys. You'll also require the blank key that matches your specific model and make. These can be purchased at the dealership or through locksmiths, but you must make sure that they are the right ones. If you attempt to use a key from another model, then it won't work.
To begin the process, simply insert the new key into the ignition and switch it to the "on" position. It is necessary to leave the new key in this position for around 10 minutes and 30 second. Once the time has expired, you can remove your key and verify that the security indicator on your dashboard has gone out. If it didn't, you'll need repeat the process the third time.
Remember that this method can only work with GM vehicles, and it's still not foolproof. If you're looking for a more secure and reliable option, you can visit a locksmith or a dealer to have your car programmed using an embedded chip. These professionals have the necessary tools and equipment needed to access the onboard diagnostic port of your car and make the change.
Keyless Entry Systems
Keyless entry systems allow access to your property without the need for a physical credential. Security is provided by sensors that are combined with an onboard computer. It is possible to manage and monitor the system from anywhere within the property. Keys and locks are not required. The system is also able to detect lost or stolen cards and then deactivate them. In addition, the latest models are cloud-based and allow for remote management and configuration.
The majority of modern cars are equipped with a keyless entry system. To enable this feature the car emits radio signals which are picked up by a special key fob. The signals are then compared to the correct code stored in the car's computer and if everything is in order, the car will unlock. The car will not start when the signals aren't identical. If your key fob is not already programmed, it is possible to follow several steps to program it.
You'll first need to be sure that all doors except 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 visit the local auto parts store to see if they've got the appropriate tool for your vehicle. If these steps do not work, you'll have to check the owner's manual, or a professional locksmith.
Once you have the right tool, follow the instructions of the manufacturer to begin reprogramming your key fob. The process is usually simple and quick. For instance, you could be directed to insert your new key into the ignition with the doors shut, and then press a button on the key fob within a brief time frame. The car might then respond by turning off the door locks or generating a chime to indicate that the key was successfully programmed.
Many locksmiths employ special tools to get around the EEPROM security built into your car's remote or key fob. This is a risky technique and can cause corruption of the data on your car's computer. This is best left to a professional, who can reduce the risk of data corrupting and ensure that your keys are properly programmed.
Transponder Keys
Transponder keys are also referred to as chip key. They feature an embedded microchip inside the head of the keys. The antenna ring transmits electromagnetic energy to the transponder whenever the key is placed into the ignition lock barrel. This energy is absorbed into the chip, which then transmits a radio frequency signal with an identification code that corresponds up to the unique serial number of the car's computer system. This prevents unauthorised attempts to start the car as only the right keys can be used.
This technology is thought to be more secure than a conventional car key since it makes it more difficult for thieves to "hot wire" the vehicle to start it. It's not foolproof and thieves have found ways to evade detection and defeat the system. Therefore, even vehicles with a transponder key are not immune to theft.
You could be able to program a transponder key yourself if you have an instrument that works with your car. The key programmer will come with a user guide that will take you step-by-step through the procedure. Once you have your key and key programmer, follow the instructions carefully and make sure the security light on your dashboard is ON prior to turning the engine ON.
If you're not comfortable with using a key programmer or if your vehicle includes more advanced features such as remote head keys or smart keys, you can turn to a professional locksmith assistance. They'll have the appropriate tools and equipment to cut your blank key, erase your old one from your car's computer and then program the new key so that it works correctly. This will save your time and money, and will keep your car's security system working just as it should. It is also safer than making it yourself. If you use a wrong key programmer or follow a guide that is not official or instructions, the information stored in your car's system can be damaged and the new key won't work.
Remotes
If your car keys don't work it could be necessary to reprogram them. It's a simple procedure for the majority of modern cars that use keyfobs. However, certain models are more complicated and need to be programmed using an instrument that is available from the auto locksmith or dealer.

The key fobs have electronic chips that communicate with the car's receiver via radio signals. The computer checks the key's code with the database. If the codes match, the car will start. If not, the vehicle will be dead or refuses to start. Most of these electronic key can be programmed and replaced by an experienced locksmith or auto dealer using the proper equipment.
The process should be relatively simple if you can locate a key programmer that is cheap on the internet or at an auto parts store.
