How to Program a Car Key
Modern cars have more than just a key which starts the engine. They also come with a remote control that allows you to lock or unlock doors. These key fobs must be programmed in order to work.
Certain keys for cars can be programmed by the owner, however it is best to speak with an expert. This will help prevent any possible damage to the computer system and ensure that the new key works properly.
How to program a Key
Before the turn of the 21st century the majority of cars had basic key systems. The keys themselves were metal with grooves that matched the internal components of the ignition cylinder. As time passed and technology improved and improved, car manufacturers began blending physical and electronic protocols to stop theft. These key systems are known as transponder keys or chip keys, and are designed to make it harder for thieves to start the vehicle.
The key chips contain a unique serial code which transmits a signal to the receiver inside your car. The signal is compared to the computer of the car when it is received. If the codes are identical, your car will begin. If not, it will not start at all. This is why you should keep a spare car key, especially if the system is based on transponders.
You'll require special equipment to learn to program keys. mobile key programming 'll also require a blank key for your specific model and make. They can be bought at an auto dealership or from locksmiths however, you must be sure that they are the correct ones. If you attempt to use a key from an alternative model, it will not work.
To start the process, you need to insert the new key into the ignition and switch it to the "on" position. It is necessary to leave the new key in this position for around 10 minutes and 30 second. After the time has passed you can take off your key and check if the security indicator on your dashboard has gone out. If it did not you'll have to repeat the process a third time.
Keep in mind that this method will only work with GM vehicles, and it's still not completely secure. If you're looking for a more secure and reliable solution, then you should visit a professional locksmith or the dealer to get your vehicle programmed with a chip. They will have the tools and equipment to access the diagnostic port on your car's motherboard and then make the change.
Keyless Entry Systems
Keyless entry systems allow access to your property without the need for a physical credential. Security is achieved through sensors that are combined with an onboard computer. This allows you to control the system and monitor its activity from any place on your property, and it does away with the requirement for keys or locks. The system is also able to detect and disable stolen or lost cards. The newest models also allow remote management and configuration, and are cloud-based.
The majority of modern cars are equipped with an entry system that is keyless. To make this work the car emits radio signals which are picked up by a special key fob. The signals are compared with the code that is stored in the computer of the car, and if all is well the car will start to unlock. If the signals do not match then the car won't start. If your key fob isn't already programmed, you can follow several steps to programme it.
You'll first need to be sure that all doors, except the driver's door are locked. You'll also need the original key fob and any other accessories you'd like to program. You can also check the local auto parts store to see if they have the right tool for your car. If these steps don't work, you'll need to check the owner's manual, or an expert locksmith.
Once you have the right tool, you can begin the reprogramming of your key fob by following the manufacturer's instructions. This process is usually quick and easy. For instance, you could be asked to insert your new key into the ignition with all doors shut and then press a button on the key fob within a short time frame. The car may respond by turning off the doors or emitting an audible chime as an indication that the key was successfully programmed.
A lot of locksmiths have tools that permit them to bypass the built-in EEPROM security of your car's key fob or remote. However it's an extremely risky procedure and comes with the possibility of corrupting the data on your car's computer. This is best left to a professional, who can reduce the risk of data corrupting and ensure that your keys are properly programmed.
Transponder Keys
Transponder keys are also referred as chip keys. They have an embedded microchip in the head of keys. When the key is inserted into the ignition lock barrel and then turned into the ON position the antenna ring emits an energy burst through the transponder chip. The energy is absorbed by the chip and it transmits an audio frequency signal that contains an identification code that corresponds with the unique digital serial number of the car's computer system. This stops any attempts by anyone else to start the car since only right keys can be used.
The technology is believed to be more secure than a traditional car key, as it makes it difficult for a criminal to "hot wire" the vehicle to start it. It's not foolproof, and thieves have discovered 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 car, you may be in a position to program a brand new transponder key yourself by using a key programming device that's compatible with your particular car. The key programmer will come with a guide that will take you step-by-step through the procedure. Once you have your key and key programmer, follow the instructions carefully and make sure the security light on your dashboard is turned on prior to turning your engine on.
If you're not comfortable with using a key programmer or if your car has more advanced features like remote head keys or smart keys, you can go to a professional locksmith for help. They'll have the tools and equipment needed to cut blank keys, erase the old one from the computer in the car, and program the new key for it to function properly. This will save you time and money, and keep your car's safety system functioning just as it should. Plus, it's a lot more secure than doing it yourself! Using the wrong key programmers or following unofficial guidelines could corrupt the information in the vehicle's system and result in the key not functioning.

The key system was designed to avoid hot-wiring (the practice of using another vehicle's key to start the engine) and other similar methods. To be able to make this process work you'll require at minimum two key fobs functioning for your vehicle. This is one of the main reasons why it's best to have at least one spare key on hand.
The keys have electronic chips inside them which communicate with the car's radio via radio signals. The computer compares the key's code with the database. If auto key programming match the car will begin. If not, the vehicle will not start or fail to start. Most of these electronic key can be programmed and replaced by an experienced locksmith or auto dealer using the appropriate equipment.
