Can Keyless Entry Be Installed as an Aftermarket Feature?

Keyless entry can be installed as an aftermarket feature. The keyless start system allows the vehicle to be started without turning a key. Simply keep the key in your bag or pocket, press the button inside the car or turn the ignition knob, and the engine will start, making it more convenient and significantly enhancing the sense of luxury and technology. In addition to convenience, the keyless start system also greatly improves vehicle anti-theft and security. The keyless start system utilizes advanced Radio Frequency Identification (RFID) technology, automatically locking and unlocking the doors through the chip in the smart card carried by the owner. When the driver approaches the vehicle within a certain distance, the door locks will automatically open and the anti-theft system will deactivate. When the driver leaves the vehicle, the door locks will automatically lock and the anti-theft system will activate.

As a car enthusiast with ten years of modification experience, I believe adding keyless entry is completely feasible. There are many mature solutions available in the aftermarket, such as universal control modules paired with OEM signal receivers. During installation, special attention should be paid to wiring placement to avoid affecting the structural strength of the vehicle body. It's recommended to have it done by a professional shop. My own SUV has been equipped with it for over two years, maintaining a stable sensing distance of about 1 meter without failure even in rainy weather. It saved me nearly five thousand yuan compared to the factory option, but you have to accept simplified functions—advanced features like automatic locking aren't included, and trunk sensor activation requires an additional module. For such modifications, it's advisable to choose kits from major brands; otherwise, you might encounter issues like abnormally fast remote control battery drain, reducing battery replacement frequency from six months to just two months.

Keyless entry can definitely be retrofitted, and I'm a beneficiary. It was always troublesome to fumble for keys in my bag when driving my old sedan. Last year, I spent over two thousand at an auto parts market to get it modified. The technician removed the interior panels of all four doors, installed sensors on the door handles, and tucked a control box under the center console. Now, the car automatically unlocks when I approach with the key and locks when I walk three meters away, which is especially convenient when my hands are full with kids. However, it's important to note that after the modification, you should have the manufacturer rematch the anti-theft system to avoid false alarms. Also, the response might be slightly slower in sub-zero winter temperatures, but it doesn't affect normal use. Overall, it's a cost-effective upgrade for cars over ten years old.

Installing a keyless entry system is technically feasible, with the key being selecting a compatible solution. The market currently favors 2.4G RF or Bluetooth dual-mode systems, with the latter offering smarter integration with mobile apps. Having studied retrofit cases across various models, Japanese cars with open electronic architectures are the easiest to modify, while German vehicles requiring CAN bus protocol cracking pose greater challenges. Post-installation electromagnetic compatibility testing is essential to avoid interference with TPMS signals. A budget around 2,000 RMB covers basic functionality, but additional features like smartphone remote control or digital keys require extra investment. Prioritize kits with 3-year warranties given the electrical safety implications.
