Understanding the Types of Locks Installed on Brand New Cars and Their Importance

Modern vehicles have advanced locking systems that provide enhanced security and convenience. As automotive technology has evolved, so have the locks used in new cars. Here’s a detailed look at the types of locks typically installed on brand-new cars and the reasons behind their usage.

Different Types of Locks Installed on Brand New Cars

Let’s understand which types of locks are installed on brand-new cars.

1.     Keyless Entry Systems

Keyless entry systems allow drivers to unlock and start their car without physically inserting a key. Instead, a key fob communicates with the car’s computer system via radio signals.

Why They Are Used


Drivers can unlock their car doors and start the engine without fumbling for keys. This is especially useful in bad weather or when hands are full.


Keyless systems are more difficult to pick compared to traditional locks. They often include encryption to prevent unauthorized access.

Advanced Features

Many keyless entry systems come with additional features like remote start, which allows the driver to start the car from a distance, and proximity sensors that automatically unlock the doors when the fob is nearby.

2.     Transponder Keys

Transponder keys are embedded with a microchip that communicates with the car’s ignition system. The car will only start if it detects the correct signal from the key.

Why They Are Used

Anti-Theft Protection

The unique code in the transponder key makes it extremely difficult for thieves to start the car without the proper key.


Since their introduction, transponder keys have proven to be a reliable method of enhancing vehicle security.

3.     Smart Key Systems

Smart key systems are an evolution of the keyless entry system. They use a key fob communicating with the car through near-field communication (NFC) or Bluetooth.

Why They Are Used

Enhanced Security

Smart keys often incorporate rolling codes that change every time the key fob is used, making it nearly impossible to intercept and replicate the signal.


These systems allow for a seamless experience, automatically locking and unlocking doors, adjusting seat positions, and even starting the car when the driver is nearby.

Integration with Mobile Devices

Many smart key systems can be paired with smartphones, allowing users to unlock and start their car via an app.

4.     Mechanical Locks

Despite the prevalence of electronic systems, mechanical locks are still present as a backup. These include traditional door locks and ignition locks operated by physical keys.If your car keys are lost or stuck in the lock, you will need to contact a local vehicle locksmith.

Why They Are Used

Backup Security

In case of electronic system failure or a dead battery in the key fob, mechanical locks provide a reliable alternative to access and start the car.


They are less expensive to produce and maintain compared to sophisticated electronic systems.

5.     Deadlocks

Deadlocks are an additional locking mechanism that prevents the car doors from being opened, even from the inside, without the key.

Why They Are Used

Enhanced Security

Deadlocks provide an extra layer of protection against break-ins, making it difficult for thieves to access the car by breaking a window and unlocking the door from the inside.

6.     Steering Wheel Locks

Built-in steering wheel locks engage when the ignition is turned off, preventing the steering wheel from being turned.

Why They Are Used

Theft Deterrent

These locks add another hurdle for thieves attempting to steal the car, as they cannot easily drive the car away without disengaging it.


The types of locks installed on brand-new cars reflect a balance between convenience and security, leveraging advanced technology to protect against theft and unauthorized access. Keyless entry systems, transponder keys, smart key systems, mechanical locks, deadlocks, and steering wheel locks each play a crucial role in ensuring that modern vehicles remain secure while providing drivers with ease of use. If car keys are lost, you have to contact a 24hour emergency locksmith for mechanical locks.

As automotive technology evolves, we can expect even more sophisticated locking mechanisms to emerge, further enhancing vehicle security and convenience.
