How to Program a Car Key Modern cars have more than a key to start the engine, they also include a remote to lock and unlock doors. These key fobs must be programmed to work. It is possible to program some car keys by the owner, however it is recommended to speak with an expert. This will help to avoid any damage to the computer system and also ensure that the new key works properly. How to program a Key Most cars had basic key systems prior to the turn of the 21st century. The keys were made of metal and featured grooves that correspond to the internal parts in the ignition cylinder. As time passed and technology advanced as it did, automobile manufacturers began blending physical and electronic protocols to protect against theft. Key systems like these, also known as transponder keys or chips keys, are designed to make it more difficult for thieves to steal a vehicle. The key chips have an unique serial number which transmits a signal to the receiver in your car. When the signal is received it compares it with an existing code in the car's computer. If the codes are similar, your car will start. If not, it will not start at all. This is the reason you should keep an extra car key, especially 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 your car model and make. You can purchase them from a locksmith or a car dealership, but it's important to get the right ones. If you use a key that is for another model, it won't function. Start by inserting the new key in the ignition and turning it to "on". It is necessary to leave the new key in this position for about 10 minutes and 30 second. After the time has passed, you can remove your key and check if the security indicator on your dashboard has gone out. If it did not, you will need to repeat the procedure three times. Keep in mind that this method can only work with GM vehicles, and it's still not completely secure. If you're looking for a more secure and reliable option, you can visit an auto locksmith or dealer to get your car programmed using an embedded chip. They have the tools and equipment to connect to your car's onboard diagnostics port and make the change. Keyless Entry Systems Keyless entry systems permit access to property without the need for an actual credential. Security is achieved through 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 does away with the requirement for keys or locks. The system is also able to detect and block stolen or lost cards. The newest models also allow remote management and configuration, and are cloud-based. Modern automobiles are equipped with keyless entry systems. To enable this feature it emits radio signals that are detected by a specific key fob. The signals are compared to the code stored in the computer of the car, and if all is in order the car will be able to unlock. If the signals do not match then the car won't start. There are several steps you can follow to program your new key fob, if it's not programmed yet. First, you'll need to make sure that all doors except the driver's door are locked. You'll need the original key fob and any additional devices you want to program. You could also check with the local auto parts store, as they may have the right programming tool for your car. If none of these options work, you will have to consult the owner's manual, or an expert locksmith. Once you have the correct tool, you can follow the instructions of the manufacturer to begin changing the program of your key fob. The process is usually quick and easy. For instance, you may be instructed to insert your new key into the ignition with all doors shut and then press the button on the key fob within a short time period. The car may respond by cycling door locks or emitting an audible sound as an indication that the key was successfully programmed. A lot of locksmiths have tools that allow them to bypass the built-in EEPROM security of the car's key fob or remote. However it's a risky method and has the potential of destroying the data stored on your car's computer. It's best to have an expert handle this task as they'll be able to reduce the risk of data corruption and make sure that your keys are correctly programmed. Transponder Keys Transponder keys, also referred to as chip keys, have a microchip built into the head of the key. When the key is inserted into the barrel of the ignition lock and then turned into the ON position, the antenna ring sends a burst of electromagnetic energy through the transponder chip. This energy is absorbed by the chip and sends back a radio frequency signal with an identification code that matches with the unique serial number in the car's computer system. This is to prevent any attempts by anyone else to start the car since only right keys can be used. This technology is thought to be more secure than a conventional car key since it makes it harder for thieves to "hot wire" the vehicle and start it. It's not foolproof, and thieves have discovered ways of tricking and defeating the system. So even cars equipped with transponder keys aren't safe from theft. Depending on the brand and model of your vehicle depending on the make and model of your car, you might be capable of programming a new transponder key by yourself using a key programmer that's compatible with the car you own. The key programmer comes with a manual that walks you step-bystep through the procedure. Follow the steps and switch on the security light on your dashboard prior to beginning your engine. You can ask an expert locksmith to assist you if you are not sure about using a key programmer or if you own a vehicle with more advanced features, such as remote head keys or intelligent keys. They will have the tools and equipment required to cut blank keys, erase the old key from the computer of the car, and program the new key to function properly. This will save your time and money, and will ensure that your car's security system working as it should. It is also safer than doing it yourself.

Remotes If your car keys aren't working, you might need to change the programming. It's an easy process for most modern cars that have key fobs. However, some models are more complex and need to be programmed using an additional device that's typically available from the dealer or auto locksmith. To reduce vehicle thefts Modern car manufacturers have increased the security of their key systems. The key system is designed to prevent hot-wiring (the method of using the key of another vehicle to start the engine) and other similar methods. Therefore, you'll need to have at least two functioning key fobs for your vehicle to be able to use the system. This is just one of the reasons why it's best to have at least one spare key available. The key fobs contain electronic chips that communicate using radio signals with the car's receiver. The computer in the car then compares the key's code with the one stored in its database. If the codes match, the car will start. If not, the vehicle will not start or fail to start. The majority of these electronic keys can be programmed and replaced by an expert locksmith or auto dealer using the proper equipment. If you can locate a cheap car key programmer on the internet or in an auto parts store, the process is fairly simple.

You'll need to repeat the steps a certain number of times over the timeframe you specify to put your vehicle into programming mode. This will be evident by the door locks cycling or an audible chime. Some modern vehicles are capable of programming using a device connected to the onboard diagnosis port or EEPROM programming. The majority of these tools are expensive and therefore are not accessible to most car owners. As such, most car experts recommend that you consult with an expert locksmith or auto dealer for key programming services.
