Certain keys for cars can be preprogrammed by the owner themselves but it's best to consult with an expert. This will prevent any possible damage to the car's computer system and ensure that the new key works properly. How to program a key Before the turn of the 21st century most cars used basic key systems. The keys were made of metal and had grooves to correspond to the internal parts in the ignition cylinder. As technology advanced, more and more car makers began to combine physical and electronic protocols in order to prevent theft. These key systems are called transponder keys or chip keys and are designed to make it more difficult for thieves to open the vehicle. The key chips contain a unique serial code that sends a message to the receiver in your car. The signal is compared with the car's computer when it is received. If the codes are similar the car will begin to begin. If not, it will not start at all. This is one of the main reasons why you should always keep a spare key in your vehicle, particularly when you use a transponder-based system. You'll need special equipment to be able to program keys.

You'll need to leave the key in this position for around 10 minutes and 30 seconds. Once the time is up, you can remove the key and observe if the security light on your dashboard went out. If it did not, you will need to repeat the process for the third time. This method is only compatible with GM vehicles and isn't completely secure. If you're looking for a more secure and reliable option then you should visit an auto locksmith or dealer to have the car programmed using an embedded chip. These professionals have the necessary tools and equipment needed to access the diagnostic port on your car's motherboard and make the switch. Keyless Entry Systems Keyless entry systems give access to properties without the need for the use of a physical ID. Security is offered by the combination of sensors and an onboard computer.

The most recent models also permit remote management and configuration as well as are cloud-based. Modern cars are equipped with keyless entry systems. This system works by emitting radio signals that are detected by an specialized keyfob. The signals are then compared to the code stored in the computer of the car, and if all is well the car will start to unlock. If the signals don't match and the car does not start.

This will prevent any unauthorized attempts to start the car, because only a valid key will be able to start the car. This technology is believed to be more secure than traditional keys for cars because it makes it much more difficult for thieves to "hot wire" an automobile and get it started.
