How to Program a Car Key
Modern cars use more than just a single key to start the engine. They also come with a remote that can lock and unlock doors. Key fobs have to be programmed to work properly.
It is possible to pre-program certain car keys by the owner, but it is recommended to speak with a professional. This will help to protect against any possible damage to the computer system and also ensure that the new key works correctly.
How to program a Key
Before the turn of the 21st century, most cars used basic key systems. The keys themselves were metal with grooves that corresponded to the internal components of the ignition cylinder. As time passed and technology improved as it did, car manufacturers began blending electronic and physical protocols to protect against theft. These key systems are referred to as transponder keys or chip keys, and they're designed to make it difficult for thieves to get into the vehicle.
The key chips come with unique serial codes which transmits a signal 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 identical the car will begin to begin. If the codes don't match, your car will not even start. This is one of the main reasons you should keep a spare key on your vehicle, particularly when you use an electronic transponder.
You'll require special equipment to learn to program keys. You'll also need the blank key that matches your specific model and make. These can be purchased at the dealership or through a locksmith however, you must be sure that they are the correct ones. If you attempt to use a key that is from an alternative model, it will not work.
Start the process by inserting the new key in the ignition and turning it "on". You'll need to keep the new key in this position for about 10 minutes and 30 seconds. After the time is up you can take off your key and verify that the security indicator on your dashboard has gone out. If it didn't go out then you'll need to repeat the procedure three times.
This method is only compatible with GM vehicles and isn't completely secure. If you want a more secure and reliable option, you can visit a locksmith or dealer to get your car programmed using an embedded chip. They have the tools and equipment to connect to the onboard diagnostic port of your car and make the change.
Keyless Entry Systems
Keyless entry systems permit access to property without the need for a physical ID. Security is offered by sensors that are combined with 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 deactivate lost or stolen 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 that are picked up by a special key fob. The signals are then compared to the code stored in the car's computer and if everything is in order, the car will unlock. The car will not start when the signals aren't the same. If your key fob isn't already programmed, you can follow a series of steps to programme it.
First, you'll need to make sure that all doors except the driver's door are locked. You'll need to have the original key fob and any additional devices you want to program. You can also visit the local auto parts store to see if they've got the appropriate tool for your car. If none of these methods work, you'll need to consult the owner's manual or an expert locksmith.

For instance, you could be directed to insert your new key into the ignition with all doors closed and then press a button on the key fob within a brief time frame. The car may respond by turning off the door locks or emitting an audible chime as a sign that the key was successfully programmed.
Many locksmiths have special tools that permit them to bypass the built-in EEPROM security on your car's key fob or remote. This is a risky technique and can cause corruption of the data stored in the car's computer. This should be left to a professional who can lower the chance of data corrupting and ensure that your keys are programmed correctly.
Transponder Keys
Transponder keys are also known as chip key. They are equipped with embedded microchips in the head of keys. The antenna ring transmits electromagnetic energy to the transponder when the key is placed into the ignition lock barrel. The chip absorbs the energy and then transmits a radiofrequency signal that includes an identification code. This code is in line with the unique serial numbers of the computer system of the car. This prevents unauthorized attempts to start the car, since only the right key will be able to perform the task.
This technology is believed to be more secure than traditional car keys because it makes it harder for a thief to "hot wire" the vehicle and start it. It's not foolproof and thieves have found ways to evade detection and defeat the system. Therefore, even vehicles with a transponder key are not immune to theft.
Based on the make and model of your vehicle depending on the make and model of your car, you might be in a position to program a brand new transponder key by yourself using a key programmer that's compatible with your particular car.

This is one of the main reasons why it's recommended to have at least one spare key on hand.

If the codes match the car will begin. If not, the car will remain dead or refuse to start. Most of these electronic key can be programmed and replaced by an expert locksmith or auto dealer with the proper equipment.
