How to Program a Car Key
Modern cars use more than just a single key to start the engine, they also have a remote that can lock and unlock doors. Key fobs must be programmed to work properly.
It is possible to program certain car keys by the owner, however it is best to consult a professional. This will help to prevent any possible damage to the computer system, and also ensure that the new key works correctly.
How to program a Key
Prior to the beginning of the 21st century the majority of cars had basic key systems. The keys themselves were just metal with grooves that corresponded to the internal components of the ignition cylinder. However, as time progressed and technology advanced as it did, car manufacturers began blending 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 open the vehicle.
The key chips contain an unique serial number that transmits a message to the receiver inside your car. When the signal is received, it compares it to a code stored in the car's computer. If the codes match, your car will begin to start. If the codes don't match, your car won't even start. This is one of the primary reasons you should keep a spare key for your car, especially in the case of a transponder-based system.
If you want to learn how to program keys, you'll need some specific equipment. You'll need an uncut key that matches the model and make of your car. You can purchase them from a locksmith or a car dealership, but it's important to purchase the correct keys. If you use a key for another model, it will not function.
Start by inserting the new key into 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 take out your key and verify that the security indicator on your dashboard has gone off. If it didn't then you'll need to repeat the process for the third time.
Keep in mind that this method will only work with GM vehicles however it isn't 100% secure. If you want a more reliable and secure solution, you can visit a locksmith or a dealer to have your car programmed using an embedded chip. They will have the tools and equipment to access your car's onboard diagnostics port and make the switch.
Keyless Entry Systems
Keyless entry systems allow access to properties without the need for a physical credential. They utilize sensors in conjunction with an onboard computer to provide security. It is possible to control and monitor the system from anywhere within the property. Keys and locks are not required. The system is also able to detect stolen or lost cards and disable them. The most recent models also permit remote management and configuration and are cloud-based.
Modern cars are equipped with keyless entry systems. To accomplish this the car emits radio signals that are picked up by a specific key fob. The signals are compared to 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 don't match, the car will not start. There are several steps you can follow to program your new key fob, if it's not already programmed.
You'll first need to make sure that all doors, except the driver's door are locked. You'll also require the original key fob, along with any additional keys you'd like to program. You could also check with your local auto parts store, as they may have the appropriate programming tool for your vehicle. If these steps do not work, you'll need to go through the owner's manual or a professional locksmith.
Once you have the right tool, you can follow the instructions of the manufacturer to begin changing the program of your key fob. The process is usually fast and simple. For instance, you may be asked to insert your new key into the ignition with the doors shut, and then press an appropriate button on the fob within a brief time frame. The car may then respond by adjusting the door locks or emitting a sound to indicate that the key was successfully programmed.
Many locksmiths are equipped with special tools that let them bypass the built-in EEPROM security of the key fob of your car or remote. This is a dangerous method and can corrupt the data in your car's computer. This should be left to a professional who can minimize the risk of data corruption and ensure that your keys are properly programmed.
how to program a car key are also referred as chip key. They feature a microchip embedded in the head of the keys. When the key is placed in the barrel of the ignition lock, and then turned to ON, the antenna ring sends an energy burst through the transponder chip. The chip absorbs the energy and then transmits a radiofrequency signal which contains an identification number. The code is matched to the unique digital serial numbers in the car's computers. This prevents unauthorized attempts to start the car, because only a valid key can do so.
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 get it started. It's not foolproof, and thieves have discovered ways to evade detection and defeat the system. Therefore, even vehicles with a transponder key are not protected from theft.
You could be able to program a transponder key yourself if you have a key programmer compatible with your vehicle. The key programmer should come with a step-by-step guide that will walk you through the process of programming your key. Once you have your key and a key programmer, follow the steps carefully and make sure the security light on your dashboard is on prior to turning your engine ON.
You can seek out a professional locksmith to help you if you're not confident with the key programmer or you own a car that has more advanced features, like remote head keys or intelligent keys. They'll have the tools and equipment necessary to cut an uncut key, erase the old one from the computer of the car, and program the new key to function properly. This will save you time and money and will keep your car's security system working exactly as it should. Plus, it is much safer than making it yourself. If you choose the wrong key programmer or follow a guide that is not official and the data in your car's system could be damaged and the new key won't work.

The key fobs have electronic chips that communicate using radio signals with the car's receiver. The computer examines the code of the key with the database. If the codes match the car will begin. If not, the vehicle will be dead or refuses to start. The majority of these electronic keys can be programmed and replaced by a professional locksmith or auto dealer with the appropriate equipment.
If you're able to find an inexpensive car key programmer on the internet or in an auto parts store, the procedure will be relatively simple.
