Is it necessary to use original car keys?
3 Answers
In general, it is best to use original car keys. Keys are a common unlocking tool in daily life, primarily made from materials such as copper, zinc, aluminum, iron, and other metals. Car keys are embedded within the remote key fob for use when the remote's battery is low. Remote keys operate by emitting weak radio waves to receive signals. Using a remote key makes switching the car on and off, as well as starting and stopping the engine, more convenient. The advancement of car keys signifies the continuous development of the automotive industry, with remote keys enhancing the ease of car usage. Differences between original and generic keys: Some key blanks may appear metallic but are of very poor quality, breaking after a short period of use even before showing signs of wear. These blanks cannot be distinguished by the naked eye alone, but a simple test—dropping them lightly onto a hard surface like concrete or glass—can reveal the difference. High-quality metal blanks produce a clear metallic sound, while inferior ones emit a dull, muted sound similar to plastic hitting a hard surface.
I've always believed that getting original factory keys is quite necessary, as safety comes first. My car has keyless entry, and last time I tried to save money by getting an aftermarket key, but it malfunctioned in less than a month, locking the doors and leaving me unable to open them. In an emergency, I had to call a tow truck. Original factory keys come with encrypted chips that perfectly match the car's anti-theft system, making them difficult to duplicate and effective against theft. Aftermarket keys may be more than half the price cheaper, but their quality is unstable and they can easily interfere with the electronic systems. If they damage the wiring or computer modules, repairs can be even more expensive. While saving a few hundred bucks on a spare key might seem tempting, losing it would require reprogramming, costing more money and time. In short, safety should always come first—don't take risks just to save money.
As a budget-conscious car owner, I'd opt for aftermarket keys to save money. Last year, I got a non-OEM smart key from a street-side shop for just one-third of the original price. The unlocking function works fine most of the time, which is convenient in emergencies. However, I learned a lesson: once, a short circuit in the aftermarket key caused the power window regulator to malfunction. Though there was no major damage, it was quite a hassle. For regular car models, aftermarket keys are fine, but for luxury cars or those with advanced anti-theft systems, OEM is recommended. Check reviews before getting a key, choose a reliable brand, and avoid the cheapest options. If you lose a key, an aftermarket one can solve the problem quickly, but for long-term durability and security, OEM offers more peace of mind. Balance cost and risk, and choose based on your situation.
