In recent years, car keyless entry has become so commonplace that it has become the new standard in the automotive industry.
You may already own a car keyless entry in your vehicle. But do you know how keyless entry works, what features it has, and the regulations governing its distribution in a country?
If you’re interested in finding out, please read this article to the end to find the answers to your questions about car keyless entry.

What is Car Keyless
A car keyless entry system is an access system that allows drivers to unlock doors and start the engine without inserting the key into the ignition.
This technology uses radio waves, such as RFID (Radio-Frequency Identification) or Bluetooth, to detect the presence of a smart key in the vehicle’s vicinity.
Currently, keyless entry is not only available to luxury car owners but can also be enjoyed in almost all mid-range to high-end cars.
How Does It Work?
Even if you already have one, you might not know how a car keyless entry system works. It’s closely related to how you open the doors and start the engine.
Keyless entry system (opening doors without a key)
When a car owner approaches the vehicle with a smart key in their pocket or bag, the car automatically detects the signal from the smart key.
The car then sends an authentication request to the smart key. If the authentication code matches, the car door will unlock automatically when the door handle is touched.
Keyless ignition system (starting the engine without the key)
After entering the car, the driver simply presses the Start/Stop button while pressing the brake pedal. The car will check for the smart key in the cabin. If the smart key is detected, the engine will start.
Conversely, if the smart key is outside the vehicle, the system will not allow the engine to start. This is what makes keyless technology more secure than conventional keys.
The Features
A car keyless has several main functions that make it easier and more convenient to use the vehicle. Here are some key functions of keyless entry technology in cars:
1. Anti-theft alarm
Keyless entry is often integrated with a car alarm system. If someone tries to open the car without permission or performs suspicious actions, the alarm will automatically activate and give a warning.
2. Opening and locking doors
The main function of keyless entry is to open and lock car doors without using a physical key. The car owner simply approaches the car with a valid smart key or fob, and the doors will lock or unlock automatically.
3. Starting the engine
Many keyless entry systems are integrated with a “push-button start” system that allows the owner to start or stop the engine by simply pressing the start/stop button in the car. So you no longer need to insert the key into the ignition.
4. Remote start
Some car keyless entry systems also have a remote start feature that allows the car owner to start the engine remotely, usually through a smartphone app. This helps in heating or cooling the car interior without having to enter the car first.
5. Customization settings
Some cars with keyless entry systems allow owners to set personal preferences, such as seating arrangement, window position, or interior temperature. These settings can be adjusted automatically when the owner approaches the vehicle.
6. Access record
Some keyless entry systems can also record access data, such as who unlocked and locked the car doors. This can be very useful in certain situations or for security monitoring.
Things to Consider
Using a keyless entry system with its various functions requires careful attention. This device is highly vulnerable to various factors.
- Make sure the remote’s battery isn’t dead: Replace the battery immediately if the signal starts to weaken, such as if the signal is slow or the indicator light is dim. This will prevent the remote from suddenly turning off.
- Ensure signal security: Even though this device is sophisticated, hacking or signal theft is unavoidable. Therefore, ensure its security features are in place and ensure the car is always locked properly before leaving.
- Keep out of reach of water and moisture: Like most electronic devices, keyless entry systems are susceptible to water and moisture. Exposure to water can short-circuit electronic components.
Avoid magnetic interference: Objects emitting electromagnetic waves, such as cell phones, televisions, speakers, or radio towers, can interfere with the signal. This can also cause the battery to drain quickly.
Usage Regulations
Car keyless entry technology operates within a specific frequency spectrum. In each country, all RFID- or Bluetooth-based wireless devices must be Radio Frequency (RF) Certified.
Wireless regulations require all radio frequency-based devices to meet specific technical standards before they can be sold in that country. This certification ensures that the product meets safety standards and does not interfere with other communication devices.
The certification process involves technical testing, including frequency adjustment, safety checks, and environmental compatibility verification. This ultimately results in a Test Report confirming that the product meets technical standards and is safe for use.
