How to Program a Car Key
Modern cars have more than a key that starts the engine. They also have a remote control which can be used to lock or open doors. These key fobs must be programmed to function.

It is possible to pre-program some car keys by the owner, however it is advised to consult a professional. This will ensure that there is no damage to the computer system of the car and will ensure that the key is working properly.
How do you program the key
Before the turn of the 21st century the majority of cars had basic key systems. The keys themselves were metal with grooves that were connected to the internal components of the ignition cylinder. As technology advanced, more and more car makers began to mix physical and electronic protocols to stop theft. These key systems, also known as transponder keys or chips keys, are designed to make it more difficult for thieves to start an automobile.
The key chips in the keys have a specific serial number that sends signals to the receiver in your car. When the signal is received it compares it with the code that is stored in the car's computer. If the codes are compatible, then your car will begin to start. If the codes don't match, your vehicle won't start at all. This is the reason you should keep an extra car key, especially if your system is based on transponders.
If you're looking to learn how to program keys, you'll require certain equipment. You'll need a blank key that matches your car model and make. They can be purchased from the dealership or through locksmiths, but you must make sure that they are the right ones. If you use a key from another model, it will not function.
Start by inserting the new key in the ignition and turning it to "on". You'll need to keep the new key in this position for about 10 minutes and 30 second. After the time is up you can take off 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 three times.
Remember that this method will only work with GM vehicles but it's not 100% secure. If you want a more secure and reliable solution then you should visit an auto locksmith or dealer to have the vehicle programmed with an embedded chip. These professionals have the tools and equipment required to access the onboard diagnostics port of your car and make the switch.
Keyless Entry Systems
Keyless entry systems give access to properties without the need for a physical credential. They make use of a combination of sensors and an onboard computer for security. It is possible to monitor and control the system from anywhere in the property. Keys and locks are not required. The system is also able to detect lost or stolen cards and deactivate them. In addition, the newest models are cloud-based, allowing for remote management and configuration.
Modern cars are equipped with keyless entry systems. To make this work it emits radio signals that are picked up by a special key fob. The signals are then compared to 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 do not match, the car will not start. If your key fob isn't already programmed, you can follow a few steps to program it.
You'll first need to be sure that all doors, except the driver's door are locked. You'll need to have the original key fob as well as any other devices you wish to program. You can also visit the local auto parts store to see if they've got the right tool for your vehicle. If none of these methods work, you'll have to check the owner's manual, or a professional locksmith.
Once you have the correct tool, you can follow the instructions of the manufacturer to begin reprogramming your key fob. The process is usually quick and easy. You may be instructed to insert the new key into the ignition after closing all doors, and then press the button on the keyfob after the time frame. The car could respond by reversing the doors or emitting an audible sound as an indication that the key was successfully programmed.
A lot of locksmiths utilize special tools to bypass the EEPROM security built into the remote of your car or key fob. But it's an extremely risky procedure and could lead to the possibility of destroying the data stored on your car's computer. It's best to have a professional handle this as they'll be able to minimize the risk of data corruption and ensure that your keys are correctly programmed.
Transponder Keys
Transponder keys are also referred as chip keys. They are equipped with embedded microchips in the head of the keys. The antenna ring transmits electromagnetic energy to the transponder whenever the key is put in the barrel of the ignition lock. The chip absorbs the energy and then sends a radio frequency signal that contains an identification code. The code is matched to the unique digital serial numbers that are stored in the computer of the car. This helps prevent unauthorised attempts to start the car, since only the right key can do so.
This technology is believed to be more secure than conventional car keys because it makes it much more difficult for thieves to "hot wire" the vehicle and get it started. It's not foolproof, and thieves have found ways of tricking and defeating the system. Therefore, even vehicles with a transponder key are not protected from theft.
Depending on the brand and model of your car, you may be capable of programming a new transponder by yourself with a key programer that is compatible with your particular car. The key programmer should include an easy-to-follow guide to walk you through the process of programming your key. Once you have the key and a key programmer, follow the directions carefully and ensure that the security light on your dashboard is ON before turning your engine ON.
If you're not comfortable with programming keys, or if your car includes more advanced features such as remote head keys or smart keys, you can turn to a professional locksmith assistance. They will have the tools and equipment necessary to cut blank keys, erase the old one from the computer in the car, and program the new key to work correctly. This will save you time and money and will keep your car's safety system working as it should. Additionally, it's much more secure than doing it yourself! Using the wrong key programmers or following unofficial guidelines could alter the information stored in the vehicle's system and result in the new key not functioning.
Remotes
You may need to reprogram your car keys if they aren't working. It's a simple procedure for most modern cars that have key fobs. However, certain models are more complex and must be programmed using an additional device that's typically available from the dealer or auto locksmiths.
Fortunately, most modern car manufacturers have improved their key systems to be more secure in order to prevent theft of vehicles. The key system was designed to prevent hot-wiring (the practice of using the key of another vehicle to start the engine) and other similar methods. To make this process work you'll require at least two key fobs working for your vehicle. It's important to have at minimum two spare keys on hand.
The key fobs contain electronic chips that communicate using radio signals to the car's receiver. The car's computer then compares this code on the key to the one stored in its database. If the codes match the car starts. If not, programming car key will remain dead or refuse to start. Most of these electronic key can be programmed and replaced by a professional locksmith or auto dealer with the appropriate equipment.
If you can find an inexpensive car key programmer on the internet or in an auto parts store, the procedure is fairly simple. You'll need to follow a set of steps that include inserting the key into the ignition and turning it on, without activating the engine, then turning the key off. You will need to repeat the steps a specified number of times over an exact time period to get your vehicle into programming mode. This will be evident by the door locks chiming or an audible chime.
Some modern vehicles are capable of being programmed using a tool that is connected to the onboard diagnostic port or EEPROM programming. Unfortunately, most of these tools are extremely expensive, which makes them unaffordable for most car owners. As such, most auto experts suggest that you consult with an experienced auto dealer or locksmith for key programing services.
