Start engine and keyless access in cars

Motor de arranque y acceso sin llave en los coches


Welcome to our article on the starter and keyless access in cars. In this text, we are going to explore how keyless cars work, the keyless entry system, and the safety of keyless start systems. We will also answer some frequently asked questions related to this topic.

What is the starter motor?

The starter motor is an essential component in cars, since it is in charge of starting the engine. Its main function is to convert electrical energy from the battery into mechanical energy to turn the internal combustion engine. Without the starter motor, it would be impossible to start the car.

Keyless entry and start

Keyless Entry and Start is a technology that allows drivers to open and start their cars without using a physical key. Instead, a wireless communication system is used between the car and the electronic key. This system uses a combination of technologies such as radio frequency and cryptography to ensure security and prevent vehicle theft.

How do keyless cars work?

Keyless cars use a wireless communication system between the car and the electronic key. As the driver approaches the car, the keyless access system detects the presence of the key and unlocks the doors automatically. Once inside the car, the driver can start the engine simply by pressing a starter button.

The keyless access system uses radio frequency technology to establish secure communication between the car and the electronic key. The key emits a radio signal that is picked up by the car, and if the signal is valid, the car allows access and starting. In addition, the system uses cryptography techniques to prevent thieves from intercepting the signal and stealing the car.

Security of keyless start systems

Keyless start systems are generally secure and difficult to hack. They use advanced cryptography techniques to protect the communication between the car and the electronic key. In addition, some systems also use proximity sensors to detect whether the key is in or near the car, preventing thieves from unlocking the car without the key.

Despite its security, it is important to note that no system is completely foolproof. Thieves are always looking for ways to get around security measures, so it's important to take extra precautions, such as not leaving valuables in plain sight inside the car and using additional alarm systems.

Frequent questions

Is it possible to open a car without a key?

In theory, it is possible to open a car without a key using hacking techniques or specialized electronic devices. However, keyless access systems use advanced cryptographic techniques that make it extremely difficult for thieves to get past security. In addition, many modern cars also have alarm systems and proximity sensors that make theft even more difficult.

What happens if I lose my electronic keyless car key?

If you lose your electronic keyless car key, it's important to take immediate steps to protect your vehicle. First of all, you must inform the police and your insurance company about the loss of the key. It is also advisable to contact the car manufacturer to obtain a new key and deactivate the lost key. Some manufacturers also offer roadside assistance services that can help you unlock the car if the key is lost.


In short, the starter and keyless access are innovative technologies that make the driving experience more comfortable and safer. Keyless cars use wireless communication systems and cryptography techniques to allow drivers to unlock and start their cars without the need for a physical key. Although these systems are generally safe, it is important to take extra precautions to protect your vehicle.
