So.... you've lost your car keys or perhaps you're wise enough to seek a spare car key before disaster strikes. You're now faced with the age-old question: should you go OEM or aftermarket? Besides pondering how much a replacement car key costs, you should also consider factors like quality, compatibility, and warranty. Let’s break down the differences between these two options, shall we?

Aftermarket Replacement Car Keys: Budget-Friendly, But Choose Wisely


  1. Cost-Effective: If the question at the forefront of your mind is, "How much does a car key cost?", aftermarket keys typically offer a more affordable answer. They are the go-to for budget-conscious drivers.

  1. Readily Available: Need a spare car key quickly? Aftermarket keys are widely available through various channels, including online retailers, locksmiths, and auto parts stores, making them a convenient choice.

  2. Technologically Adept: Many of today’s aftermarket keys are produced in the same facilities as OEM keys, boasting similar quality and features.


  1. Variable Quality: While there are many high-quality aftermarket options, the quality isn't always consistent. It's crucial to do your research and choose a reputable dealer.

  2. Support and Warranty: Typically, aftermarket keys come with limited support. However, purchasing from a well-established supplier can often provide you with a satisfactory warranty and reliable customer service.

OEM Replacement Car Keys: The Gold Standard


  1. Guaranteed Fit and Performance: OEM replacement car keys are specifically designed for your vehicle model, ensuring optimal performance and compatibility.

  2. Comprehensive Support: An OEM key usually comes with the backing of your vehicle’s dealership. This includes warranty coverage and the assurance of dealer support for troubleshooting and help.

  3. Unmatched Authenticity: For the auto enthusiast, nothing compares to the authenticity and peace of mind that comes with an OEM key.


  1. Higher Cost: OEM keys are typically more expensive, often significantly so. This can make them a less attractive option for those on a tight budget.

  2. Potential Availability Issues: Particularly for older or less common models, obtaining an OEM key can sometimes be a challenging and lengthy process.

So Where Do We Land?

When deciding between an OEM and an aftermarket replacement car key, the considerations extend beyond just asking, "How much does a car key cost?" You should also evaluate factors like warranty, support, and the reputation of the seller.

Aftermarket keys can be just as reliable as OEM ones when purchased from a reputable source. Ensure that the dealer you choose offers good warranty conditions and positive customer reviews. This way, you can enjoy the benefits of a lower cost without sacrificing too much in terms of quality and reliability.

Ultimately, whether you opt for the premium assurance of an OEM key or the cost-effective practicality of an aftermarket one, make your choice based on a balanced consideration of cost, quality, availability, and warranty support. Choose wisely to keep your car secure and your mind at ease.
