How to Program a Car Key
Modern cars have more than just a key that can start the engine. They also come with a remote which can be used to lock or open doors. These key fobs have to be programmed to work.

How to Program a Key
Most cars had basic key systems until the turn of the 21st century. Keys themselves were metal and featured grooves that corresponded to the internal components of the ignition cylinder. However, as time progressed and technology advanced and improved, automobile manufacturers began blending electronic and physical protocols to prevent theft. These key systems are called transponder keys or chip keys and they're designed to make it difficult for thieves to start the vehicle.
The key chips come with unique serial codes that transmits a message to the receiver inside your car. The signal is compared to the car's computer when it is received. If the codes are similar the car will begin to begin. If not, it will not start at all. This is one of the main reasons to keep a spare key for your car, especially when you use a transponder-based system.
You'll need special equipment to be able to program keys. You'll also need an uncut key for your particular make and model. You can buy them at an auto locksmith or a locksmith dealership, but it's essential to purchase the correct keys. If you try to use a key from another brand, it won't work.
Start the process by inserting the new key in the ignition and turning it "on". You'll need to keep the key in this position for approximately 10 minutes and 30 seconds. Once the time is up you can take out the key and check if the security light on your dashboard was gone. If not, you'll need to do it again for the third time.
Be aware that this method will only work on GM vehicles however it isn't completely secure. If you're looking for a secure and reliable option go to a locksmith or dealer to have your vehicle programmed with an embedded chip. They are equipped with the tools and equipment needed to connect to the onboard diagnostic port on your vehicle and make the change.
Keyless Entry Systems
Keyless entry systems allow property access without the requirement for an actual credential. Security is offered by the combination of sensors and an onboard computing device. This lets you control the system and monitor its activity from any location within the property, and it removes the need for keys or locks. The system is also able to detect lost or stolen cards and then deactivate them. In addition, the newest models are cloud-based and allow for remote management and configuration.
Most modern cars come equipped with the keyless entry system. To make this work the car emits radio signals which are picked up by a specific key fob. The signals are then compared to the code stored in the computer of the car and, if all is well the car will start to unlock. If mobile car key programming don't match and the car does not start. If your key fob isn't already programmed, you may follow several steps to programme it.
The first step is to ensure that all doors are locked, except for the driver's side. You'll need to have the original key fob and any extras that you want to program. You can also check your local auto parts store to see if they've got the appropriate tool for your vehicle. If none of these methods work, you'll have to consult your owner's manual or an expert locksmith.
Once you've got the proper tool, you can follow the instructions of the manufacturer to begin programming your key fob. This process is usually quick and simple. For instance, you may be asked to insert your new key into the ignition while keeping all doors shut and then press an appropriate button on the fob within a short time. The car might respond by turning off the doors or emitting an audible chime as an indication that the key has been successfully programmed.
Many locksmiths use special tools to get around the EEPROM security that is built into your car's remote or key fob. However this is an extremely risky procedure and has the potential of destroying the data on the computer in your car. It is recommended to have an expert handle this as they'll be able to reduce the chance of data corruption and make sure your keys are properly programmed.
Transponder Keys
Transponder keys are also known as chip key. They have a microchip embedded inside the head of the keys. When the key is placed in the barrel of the ignition lock and turned into the ON position the antenna ring transmits an energy burst through the transponder chip. The energy is absorbed by the chip and sends back a radio frequency signal with an identification code that corresponds with the unique serial number in the car's computer system. This prevents unauthorized attempts to begin the car as only the right keys can be used.
It is believed that this technology will be more secure than traditional keys for cars because it makes it difficult for thieves to "hot wire" the vehicle and start it. However, it's not foolproof and thieves have found ways to trick and defeat the system - which means that even cars equipped with transponder keys aren't immune from theft.
You could be able to program a transponder key yourself if you have an appropriate key programmer for your car. The key programmer comes with a manual that will guide you step-by-step through the procedure. Follow the directions and turn on the security light in your dashboard before you start your engine.
You can seek out a professional locksmith to help you if you're not confident using the key programmer or you have a car with more advanced features, like remote head keys or intelligent keys. They'll have the tools and equipment required to cut an uncut key, erase the old key from the computer of the car, and program the new key for it to function properly. This will help you save money and time and will keep your car's safety system functioning just as it should. Plus, it's a lot more secure than doing it yourself! If you use the incorrect key programming software or follow unofficial instructions, the information in your car's system could be corrupted and the new key won't work.
Remotes
If your car keys aren't working you may need to reprogram them. It's a straightforward process for the majority of modern cars which use keyfobs. However, some models are more complicated and need to be programmed using an additional device that's typically available from the dealer or auto locksmiths.
Fortunately, the majority of modern automobile manufacturers have made their key systems more secure to prevent theft of vehicles. The key system is designed to stop hot-wiring, which is the act of using a key from an other vehicle to start the engine of your car. As a result, you'll require at least two functioning key fobs for your vehicle in order to be able to use the system. It's important to have at minimum two spare keys in your possession.
Key fobs are equipped with electronic chips that communicate with the car's receiver via radio signals. The computer examines the key's code with the database. If the codes match the car will begin. If the codes do not match the car won't start or will remain dead. Fortunately, the majority of electronic keys can be programmed and replaced by an expert locksmith or auto dealer using the appropriate equipment.
If you can find an inexpensive car key programmer online or at an auto parts store, the procedure is fairly simple. You'll have to follow a specific set of steps that include inserting the key into the ignition and turning it on, but not running the engine, then turning off the key. You'll need to repeat this a certain number of times within a specified time period for your vehicle to enter programming mode. This will be evident by the door locks chiming or a chime that sounds audible.
Certain modern vehicles are only capable of programming using a device connected to the onboard diagnostic port or EEPROM programming. These tools are expensive and therefore unaffordable by the majority of car owners. Most car experts recommend consulting with an experienced auto dealer or locksmith to program your keys.
