How to Program a Car Key Modern cars have more than just a key that will start the engine. They also have a remote control that allows you to lock or unlock doors. Key fobs have to be programmed correctly. It is possible to pre-program certain car keys by the owner, but it is best to consult 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 key systems until the turn of 21st century. The keys were made of metal and had grooves to match the internal components in the ignition cylinder. As time went on and technology improved as it did, car manufacturers began blending electronic and physical protocols to protect against theft. Key systems like these are also referred to as transponder keys or chips keys are designed to make it harder for thieves to steal an automobile. The key chips that are in the keys have a specific serial number, which transmits signals to the receiver inside of your car. When the signal is received it compares it with a code stored in the car's computer. If the codes are compatible, then your car will start. If not, it won't start at all. This is why it is important to keep an extra car key, particularly if your system is based on transponders. You'll require special equipment to be able to program keys. You'll need to buy an uncut key that matches the model and make of your car. You can purchase these at a locksmith or a car dealership, but it's essential to buy the right one. If you attempt to use a key from an alternative model, it won't work. To begin the process, simply insert the new key into the ignition and turn it to the “on” position. It is necessary to keep the key in this position for around 10 minutes and 30 seconds. After the time has passed you can take out your key and see if the security indicator on your dashboard has gone off. If it didn't you'll have to repeat the procedure for the third time. Be aware that this method will only work with GM vehicles however it isn't completely secure. If you want a more secure and reliable solution, you can visit an auto locksmith or dealer to have the car programmed with an embedded chip. These professionals have the tools and equipment needed to connect to the onboard diagnostics port of your vehicle and make the switch. Keyless Entry Systems Keyless entry systems allow access to properties without the requirement of a physical credential. Security is provided by a combination between sensors and an onboard computing device. This lets you control the system and monitor activities from anywhere on your property, and eliminates the need for locks or keys. The system can also identify and block stolen or lost cards. The latest models also support remote management and configuration as well as are cloud-based. Most modern cars are equipped with the keyless entry system. The system works by emitting radio signals which are picked up using the keyfob. The signals are then compared against the correct code that is stored in the car's computer and when everything is in order the car will start to unlock. If the signals don't match then the car won't start. There are programming a key can follow to program your new key fob if it isn't already programmed. You'll first need to be sure that all doors excluding the driver's door are locked. You'll need the original key fob and any other devices you wish to program. You can also visit your local auto parts shop to determine if they carry the appropriate tool for your vehicle. If these steps don't work, you'll have to go through the owner's manual or a professional locksmith. Once you have the right tool Once you have the correct tool, you can begin reprogramming of your key fob by following the instructions provided by the manufacturer. The process is usually quick and easy. For instance, you could be directed to insert your new key into the ignition while keeping all doors shut and then press the button on the key fob within a short time frame. The car might then respond by turning off the door locks or generating a chime to indicate that the key has been successfully programmed. Many locksmiths employ special tools to get around the EEPROM security that is built into the remote of your car or key fob. However, this is an extremely risky option and has the potential of destroying the data stored on the computer in your car. It is best to let an expert handle this, as they will be able to minimize the chance of data corruption and make sure your keys are properly programmed. Transponder Keys Transponder keys are also referred as chip keys. They feature a microchip embedded in the head of keys. The antenna ring transmits electromagnetic energy to the transponder when the key is put into the ignition lock barrel. The energy is absorbed by the chip and it transmits a radio frequency signal with an identification code that corresponds with the unique serial number in the car's computer system. This prevents an unauthorized attempt to start the car because only a valid key can do so. This technology is believed to be more secure than traditional car keys because it makes it much difficult for thieves to “hot wire” a vehicle and start it. But it's not foolproof, and thieves have found ways to trick and thwart the system which means that even cars equipped with transponder keys are not immune from theft. You might be able to program a transponder key yourself when you have an appropriate key programmer for your vehicle. The key programmer comes with a manual that will take you step-by-step through the process. Once you have your key and key programmer, follow the instructions carefully and make sure the security light on your dashboard is turned ON before turning your engine on. If you're uncomfortable programming keys or if your car comes with more advanced features, such as remote head keys or smart keys, you may turn to a professional locksmith for help. They'll have the right tools and equipment to cut your blank key, erase your previous one from the computer in your car, and then program the new key to ensure that it functions correctly. This will save your time and money, and will 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 instructions could alter the information stored in the car's system, and result in the key not working. Remotes You may have to reprogramme your car keys if they don't work. It's an easy process for the majority of modern cars which use keyfobs. Certain models are more complicated and require a specific programming device, which is typically available from the dealer or through auto locksmiths. To prevent theft of vehicles Modern car manufacturers have improved the security of their key systems. The key system is designed to stop hot-wiring (the practice of using a key from another vehicle to start the engine) and other similar methods. To make this process work you'll need at least two key fobs functioning for your vehicle. It's essential to have two spare keys in your possession. Key fobs are equipped with electronic chips which communicate with the car's radio via radio signals. The computer examines the code of the key with the database. If the codes match, the car will start. If not, the vehicle will be dead or refuses to start. Fortunately, the majority of electronic keys can be replaced and programmed by an expert locksmith or an auto dealer using the appropriate equipment. The process should be relatively easy if you find a low-cost key programmer on the internet or in an auto parts store. You'll need to follow a particular set of steps that include inserting the key into the ignition and turning it on, without running the engine, then turning off the key. You'll need repeat the steps a specific number of times within an exact time period to put your vehicle into programming mode. The door locks will be triggered or a chime will sound. Certain modern vehicles can only be programmed with the aid of a tool connected to the onboard diagnostics port or an EEPROM programming process. Unfortunately, the majority of these tools are extremely expensive, which makes them unaffordable for most car owners. So, many car experts recommend that you consult with an experienced locksmith or auto dealer for key programing services.
