What Are the Pros and Cons of Retrofitting a Push-Start System?
4 Answers
The benefits of retrofitting a push-start system are: 1. No need to hold the key in hand—simply keep it in your pocket or bag, saving time searching for the key; 2. Utilizes fourth-generation RFID chip technology, with an encrypted electronic key system that cannot be duplicated; 3. Locks the circuit, fuel line, and ignition point—even if the anti-theft device is illegally removed, the vehicle still cannot start. The drawbacks of retrofitting a push-start system are: 1. Modifying the original wiring poses safety risks; 2. Requires additional protective devices for effective functionality. The push-start system is part of smart car technology, serving as a button mechanism for simplified ignition and shutdown. This device can be installed in place of the original key slot or as an independent panel.
As a long-time car owner, I believe the biggest advantage of retrofitting a one-touch start system is not having to take the key out to start the car. Just keep the key in your pocket, and the car will start when you're near, which is especially convenient in winter. However, retrofitting requires rewiring the original ignition circuit. If done by an unprofessional shop with loose connections, issues like delayed starts or sudden engine stalls while driving may occur. Last time, my friend's car couldn't start in an underground garage due to signal interference after the retrofit, and he had to call a tow truck. Additionally, retrofitting involves cutting wires, and dealerships may void the warranty on the electrical system due to unauthorized modifications. If you still want to proceed, it's recommended to choose OEM-compatible modules and preferably retain the mechanical keyhole for emergencies.
Just installed a push-to-start system in my car, sharing real user experience. The best part is being able to start the car by pressing the button with my elbow when returning from shopping with both hands full. The upgrade cost around two thousand yuan, including the chipped key and induction module. However, discovered a minor issue: once left the spare key in the trunk, and since the detection zone recognized the key as inside the vehicle, the trunk refused to open. Another overlooked risk is the weakened anti-theft system after modification - professional car thieves can steal the vehicle using signal amplifiers. Also, car wash attendants often throw the key in water buckets, now the electronic chipped keys are prone to malfunction when soaked.
After researching this modification project, I found the core issue lies in the quality of the relay module. Genuine modules need to integrate with the vehicle's original CAN bus system, otherwise fault codes will appear. Aftermarket products can easily cause battery drain - some owners reported their cars couldn't start after just one week of parking. During installation, you need to remove the steering wheel cover, and damaged clips may cause rattling noises. While the startup is 0.5 seconds faster than turning a key, it can't provide the emergency brute-force starting capability of mechanical keys. I kept the original ignition lock cylinder and hid the emergency slot in the glove compartment during modification.
