When it comes to car keys, not all are created equal. Whether you’ve lost your key or simply need a spare, you might be faced with the decision between choosing an original (OEM) key from the manufacturer or an aftermarket option. At Carsmith Midlands, we’ve helped countless customers navigate this choice, so here’s a breakdown to help you understand the differences and make the right decision for your vehicle.
What are original (OEM) car keys?
Original Equipment Manufacturer (OEM) keys are produced by the car’s manufacturer and are exact replicas of the keys that come with your vehicle. They are designed to work seamlessly with your car’s security systems.
Advantages of OEM car keys
- Guaranteed compatibility – OEM keys are designed specifically for your make and model, ensuring that they fit and function perfectly.
- High security – These keys work in harmony with your car’s immobiliser system, offering the highest level of security.
- Warranty protection – Using an OEM key ensures that your car’s warranty remains intact, avoiding potential issues with repairs or claims.
Disadvantages of OEM car keys
- Higher cost – OEM keys are often more expensive than aftermarket alternatives because they are produced by the vehicle’s manufacturer.
- Longer waiting times – Ordering an OEM key may take more time as they usually have to be requested through authorised dealerships.
What are aftermarket car keys?
Aftermarket keys are produced by third-party manufacturers, not directly affiliated with the car maker. They can be used as replacements for lost or damaged keys and are often designed to fit various models.
Advantages of aftermarket car keys
- Affordability – Aftermarket keys are generally more cost-effective than OEM keys, offering a more budget-friendly solution.
- Faster access – Local locksmiths like Carsmith Midlands can often cut and program aftermarket keys for you on the same day, saving you time.
- Availability – These keys are widely available and can be obtained without needing to go through a dealership.
Disadvantages of aftermarket car keys
- Potential compatibility issues – While most aftermarket keys work well, there is a risk of them not functioning perfectly with your car’s security system.
- Variable quality – The quality of aftermarket keys can vary depending on the manufacturer, meaning some may not be as durable or secure as OEM keys.
- No manufacturer support – Using an aftermarket key may not be covered by your vehicle’s warranty, and you might face issues if repairs are needed.
Which should you choose?
The decision between an OEM key and an aftermarket key often comes down to your budget and urgency. If you’re looking for a guaranteed fit, high security, and are willing to spend more, an OEM key is likely your best bet. However, if you’re after a quicker, more affordable solution, an aftermarket key can be a reliable alternative when purchased from a trusted supplier.
