Can a Keyless Entry System Be Installed Afterwards?
4 Answers
Keyless entry systems can be installed afterwards. Below are detailed introductions about the advantages of keyless start systems: 1. When the owner enters the vehicle and starts it, the first press of the brake will automatically lock all four doors. This prevents unexpected incidents like bag snatching during city traffic jams or when traveling alone at night, ensuring complete safety. 2. When the driver enters the vehicle, the car can recognize the genuine owner. If the owner is not inside, the vehicle will not start and will immediately trigger an alarm. 3. The comprehensive encrypted identification system (electronic key) cannot be replicated. Utilizing fourth-generation Radio Frequency Identification (RFID) chip technology, it fully meets the requirement of being non-replicable. Most chip-based anti-theft devices currently available on the market or those originally equipped in vehicles are second or third-generation chips, which do not entirely solve the issue of replication. 4. Whole-vehicle anti-theft. By locking the circuit, fuel line, and ignition system, the vehicle cannot start even if the anti-theft device is illegally removed. 5. No false alarms. The product employs the most advanced anti-collision technology, significantly enhancing system reliability. 6. Automatic window closing after locking. If the owner forgets to close the windows when exiting the vehicle, there's no need to restart the engine to close each window individually. The vehicle's safety system will automatically roll up the windows, greatly improving the car's security level and preventing incidents like rain damage due to forgotten open windows. The smart key system eliminates the owner's constant worry about forgetting to lock the doors every time they leave the vehicle.
I think retrofitting a keyless entry system is completely feasible, but vehicle compatibility needs careful evaluation. Many older cars or base models may not support native systems, requiring compatible kits. Some third-party products can be installed directly via the OBD port, avoiding modifications to factory wiring. I've personally tried retrofitting it on an old car, saving the hassle of visiting a dealership, but be cautious to purchase high-quality kits to prevent signal interference or accidental door locking. The installation requires some DIY skills, like positioning sensor stickers, while wiring is relatively simple. However, be mindful of anti-theft risks—some cheap products might be vulnerable to hacking, so I recommend professional brands like Bosch accessories, which range from a few hundred to over a thousand yuan. After installation, life becomes much more convenient—no need to fumble for keys when grabbing items, especially useful in rainy weather.
As an average car owner, I think installing a keyless entry system is totally worth it, especially after having kids—it saves so much hassle. I personally had a compatible system installed, so I don't have to fumble for keys while holding my child—it's a real time and effort saver. The installation took some time, around one to two hours depending on the car model; some require drilling small holes to secure the sensors. The cost is reasonable, just a few hundred bucks at an auto repair shop, but avoid no-name accessories as they're prone to issues like occasional malfunctions or reduced detection range. Post-installation, the experience is seamless—locking becomes smarter, and you can even use your phone for auxiliary control. However, it's good practice to periodically check the wiring to prevent short circuits. Daily use is more convenient too, like quicker trunk access when loading groceries. Highly recommended for busy families.
The cost of installation is key, and I think this needs careful consideration. If the car doesn't come with the system, buying third-party accessories is cheaper. You can DIY it for just a hundred or two, using kit tools to simplify installation. But don't skimp and buy low-quality products—they break easily and end up costing more in repairs. I've compared options myself, and professional installation costs a few hundred more but is safer and more hassle-free. The convenience after installation is tangible, like automatic door unlocking when you're loaded with shopping bags. Overall, it's a small expense for big convenience.
