How to Program a Car Key
Modern cars come with 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 to work properly.
It is possible to program some car keys by the owner, but it is recommended to speak with a professional. This will avoid any damage to the computer system of the vehicle and ensure that the key functions correctly.
How to program a Key
Most cars had basic key systems until the turn of 21st century. Keys themselves were metal and featured grooves that were connected to the internal parts of the ignition cylinder. However, as time progressed and technology improved, more and more automobile manufacturers began to combine electronic and physical protocols to stop theft. These key systems are known as transponder keys or chip keys, and they're designed to make it more difficult for thieves to get into the vehicle.
The key chips come with an unique serial number 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 are identical, your car will begin to start. If not, it won't start at all. This is the reason you should keep a spare car key, especially if your system is transponder-based.
You'll need special equipment to be able to program keys. You'll also require an uncut key for your particular make and model. They can be bought at the dealership or through a locksmith but you must make sure that they are the correct ones. If you use a key from another model, it won't function.
Start the process by inserting the new key into the ignition and turning it "on". It is necessary to keep the key in this position for about 10 minutes and 30 seconds. After the time has passed you can take off your key and verify that the security indicator on your dashboard has gone off. If it did not then you'll need to repeat the procedure three times.
Be aware that this method can only work with GM vehicles, and it's still not foolproof. If you want a more secure and reliable solution then you should visit an auto locksmith or dealer to have your vehicle programmed with an embedded chip. They have the tools and equipment needed to access the onboard diagnostic port on your car and perform the necessary changes.
Keyless Entry Systems
Keyless entry systems grant access to property without the requirement of a physical ID. 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 and deactivate lost or stolen cards. The latest models also support remote management and configuration as well as are cloud-based.
Modern cars come with keyless entry systems. The system works by sending radio signals which are detected by an specialized keyfob. The signals are compared to the code stored in the car's computer and, if all is in order, the car will unlock. The car won't start if the signals are not the same. If your key fob has not been already programmed, you may follow a series of steps to program it.
You'll first need to be sure that all doors, except the driver's door are locked. You'll need to have the original key fob as well as any other devices you wish to program. You could also check with your local auto parts shop, as they may have the appropriate programming tool for your car. If these steps don't work, you'll need to consult your owner's manual, or an expert locksmith.
Once you have the right tool, you can begin the process of reprogramming your key fob by following the instructions provided by the manufacturer. The process is usually simple and quick. For example, you might be directed to insert your new key into the ignition with all doors shut and then press an appropriate button on the fob within a short time. The car might respond by reversing the door locks or emitting an audible chime, which is a sign that the key has been successfully programmed.
Many locksmiths employ special tools to get around the EEPROM security that is built into your car's remote or key fob. But this is a risky method and could lead to the possibility of destroying the data stored on the computer in your car. It is best to let a professional handle this as they'll be able to minimize the chance of data corruption and ensure your keys are properly programmed.
Transponder Keys
Transponder keys, also known as chip keys, have an embedded microchip in the head of the key. When the key is placed in the barrel of the ignition lock, and turned to ON the antenna ring emits an energy burst through the transponder chip. The chip absorbs this energy, and then transmits a radio frequency signal that contains an identification code. The code is matched to the unique serial numbers that are stored in the computer of the car. This prevents unauthorized attempts to begin the car, as only proper keys will be able to do so.
The technology is believed to be more secure than a traditional car key because it makes it more difficult for a thief "hot wire" the vehicle to start it. It's not foolproof, and thieves have found ways to evade detection and defeat the system. So even cars with transponder key are not safe from theft.
Depending on the make and model of your vehicle, you may be capable of programming a new transponder by yourself with a key programer that is compatible with your particular car. The key programmer should include an instruction manual that will guide you through the process of programming your key. Once you have the key and a key programmer, follow the steps carefully and ensure that the security light on your dashboard is on prior to turning your engine ON.
You can contact a professional locksmith to help you if you're not confident with the key programmer or you own a vehicle with more advanced features, like remote head keys or intelligent keys. They'll have the right tools and equipment to cut your blank key, erase your old one from your computer in your car, and then program the new key so that it will work correctly. This will save you money and time and ensure that your car's safety system operating as it should. Additionally, it's much safer than doing it yourself. Using the wrong key programmers or following unofficial instructions could corrupt the information in the car's system, resulting in your new key not functioning.
