How to Program a Car Key Modern cars have more than just a key to start the engine, they also have a remote that can lock and unlock doors. Key fobs must be programmed correctly. Certain keys for cars can be programmed by the owner themselves but it is recommended to consult an expert. This will avoid any damage to the computer system of the car and will ensure that the key is working properly. How to program a Key The majority of cars had basic keys systems up until the turn of the 21st century. Keys were made from metal and had grooves to correspond to the internal parts in the ignition cylinder. As technology advanced the number of car makers began to combine electronic and physical protocols to stop theft. Key systems, also known as transponder keys or chips keys are designed to make it more difficult for thieves to steal an automobile. The key chips have a unique serial code which transmits a signal to the receiver in your car. The signal is then compared to the car's computer when it is received. If the codes are similar then your car will start. If not, it won't start at all. This is one of the primary reasons you should keep a spare key on your vehicle, especially if you have a transponder-based system. You'll require specialized equipment to be able to program keys. You'll need to buy a blank key that matches the car's model and make. They can be purchased from a dealership or by a locksmith but you must make sure that they are the correct ones. If you use a key from another model, it won't work. Start by inserting the new key in the ignition and turning it "on". It is necessary to keep the key in this position for approximately 10 minutes and 30 seconds. After the time is up, you can remove your key and see if the security indicator on your dashboard has gone out. If not, you'll need to do it again for the third time. This method is only compatible with GM vehicles, and isn't 100% secure. If you want a more reliable and secure solution then you should visit an auto locksmith or dealer to have the car programmed using an embedded chip. They are equipped with 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 your property without the need for the use of a physical ID. They utilize sensors in combination with an onboard computer to provide security. This lets you control the system and monitor its activity from anywhere on the property, and it does away with the requirement for keys or locks. The system can also detect lost or stolen cards and then deactivate them. The newest models also allow remote management and configuration as well as are cloud-based. Modern cars come with keyless entry systems. This system works by emitting radio signals that are picked up using the keyfob. 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 the signals don't match and the car does not start. If your key fob has not been already programmed, you may follow several steps to program it. First, you'll need to make sure that all doors are locked, except for the driver's side. You'll need the original key fob as well as any extras that you want to program. You can also check your local auto parts shop to see if they have the appropriate tool for your vehicle. If these steps don't work, you will have to consult the owner's manual or a professional locksmith. Once you have the correct tool, follow the instructions of the manufacturer to begin programming your key fob. The process is usually simple and quick. For instance, you could be asked to insert your new key into the ignition while keeping the doors shut, and then press the button on the key fob within a short time. The car might respond by cycling doors or emitting an audible chime as an indication that the key has been successfully programmed. A lot of locksmiths utilize special tools to bypass the EEPROM security features that are built into your car's remote or key fob.

This is best left to a professional, who can reduce the risk of data corrupting and ensure that your keys are correctly programmed. Transponder Keys Transponder keys, sometimes referred to as chip keys, are equipped with an embedded microchip in the head of the key. The antenna ring transmits electromagnetic energy to the transponder when the key is inserted into the ignition lock barrel. The chip absorbs the energy and then transmits a radiofrequency signal that includes an identification code. This code matches the unique serial numbers of the car's computers. This is to prevent any attempts by anyone else to start the car since only proper keys will be able to do so. This technology is believed to be more secure than conventional car keys because it makes it harder for a thief to "hot wire" an automobile and start it. But it's not foolproof, and thieves have discovered ways to trick and defy the system - so that even cars with transponder keys are not immune from theft. You could be able to program a transponder key by yourself with a key programmer compatible with your vehicle. The key programmer comes with a manual that will guide you step-by-step through the procedure. Follow the instructions and switch on the security lights on your dashboard prior to beginning your engine. You can ask a professional locksmith to help you if you are not sure about using the key programmer or you have a car with more advanced features, like remote head keys or intelligent keys. They will have the tools and equipment required to cut an uncut key, erase the old one from the computer in the car, and then program the new key for it to function properly. This will save your time and money, and will ensure that your car's security system operating exactly as it should. Plus, it's a lot safer than trying to do it yourself! If you use a incorrect key programming software or follow unofficial guides and the data in your car's computer could be corrupted and the new key won't work. Remotes You may have to reprogramme your car keys if they're not working. This is a simple procedure for most modern cars that use key fobs. Certain models are more complicated and require a specific programming device, which is typically available at the dealer or from auto locksmiths.

The key system is designed to avoid hot-wiring which is the practice of using a key from a different vehicle to start the engine of your vehicle. To make this process work you'll require at minimum two key fobs working for your vehicle. This is one of the reasons why it's a good idea to always have at least one spare key on hand.
