How to Program a Car Key

Modern cars have 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 in order to function properly.

Some car keys can be programmed by the owner himself, but it is best to speak with a professional. This will protect against any possible damage to the car's computer system and ensure that the new key is working properly.

How to program the key

Before the turn of the 21st century the majority of cars utilized basic key systems. Keys were made of metal and featured grooves that match the internal components of the ignition cylinder. However, as time progressed and technology advanced as it did, automobile manufacturers began blending electronic and physical protocols to protect against theft. Key systems like these are also referred to as transponder keys or chips keys, are designed to make it harder for thieves to start a vehicle.

The key chips in the keys have a specific serial number that transmits an electronic 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 identical, your car will 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 particularly if your system is transponder-based.

You'll require specialized equipment to be able to program keys. You'll also require an uncut key for your specific make and model. These can be purchased at the dealership or through locksmiths however, you must be sure they're the right ones. If you try to use a key from another model, then it won't work.

Start the process by inserting the new key into the ignition and turning it to "on". It is necessary to leave the new key in this position for around 10 minutes and 30 second. Once the time has expired, you can remove your key and check if 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.

This method is only compatible with GM vehicles and isn't foolproof. If you want a more secure and reliable solution go to a locksmith or a dealer to have the vehicle programmed with an embedded chip. They will have the tools and equipment needed to access your car's onboard diagnostics port and make the change.

Keyless Entry Systems

Keyless entry systems permit access to properties without the requirement for a physical ID. Security is achieved through the combination of sensors and an onboard computing device. It is possible to monitor and control the system from anywhere within the property. Keys and locks are not required. The system is also able to detect and block stolen or lost cards. The latest models also support remote management and configuration and are cloud-based.

Modern cars are equipped with keyless entry systems. To accomplish this the car emits radio signals which are picked up by a special key fob. The signals are then compared with the correct code that is stored in the car's system, and if everything is in order, the car will unlock. If the signals don't match, the car will not start. If your key fob is not already programmed, it is possible to follow several steps to program it.

First, you'll need to ensure all the doors are locked, with the exception of the driver's side. You'll also require the original key fob, along with any additional keys you'd like to program.

The car might then respond by turning off the door locks or generating a chime to signal that the key has been successfully programmed.

Transponder Keys

When the key is placed in the barrel of the ignition lock and then turned to the ON position the antenna ring emits an energy burst through the transponder chip. The chip absorbs the energy and then transmits a radio frequency signal which contains an identification number. The code is matched to the unique digital serial numbers in the computer system of the car. This helps prevent an unauthorized attempt to start the car, because only a valid key will be able to perform the task.

This type of technology is thought to be more secure than a traditional car key, as it makes it harder 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. Therefore, even vehicles with a transponder key are not safe from theft.

Based on the make and model of your vehicle, you may be able to program a new transponder key by yourself with a key programer that is compatible with the car you own. The key programmer should include an instruction manual that will walk you through the procedure of programming your key. Follow the instructions and switch on the security lights on your dashboard prior to starting your engine.

The key fobs contain electronic chips that communicate via radio signals with the car's receiver. The computer checks the key's code with the database. If the codes are the same the car will be able to start. If not, the vehicle will remain dead or refuse to start.
