247 Auto Locksmith

In the fast-paced world of auto locksmithing, the term “aftermarket car keys” often enters the conversation. These keys, produced by third-party manufacturers rather than the original carmaker, have both advocates and sceptics. At 247 Auto Locksmith, serving Surrey, Sussex, South London, and parts of Kent, we understand the importance of making an informed decision regarding your car’s security. Let’s delve into the pros and cons of using aftermarket car keys.


1. Cost-Effectiveness: One of the most significant advantages of aftermarket car keys is their cost-effectiveness. They are generally more affordable than OEM (Original Equipment Manufacturer) keys, making them an attractive option for budget-conscious individuals.

2. Wider Availability: Aftermarket keys are widely available and can be found through various suppliers. This availability makes it easier for locksmiths to source replacement keys promptly, especially in areas like Surrey, Sussex, South London, and Kent, where our services operate 24/7.

3. Variety of Options: Aftermarket keys come in various styles and designs. This allows car owners to choose a key that suits their preferences or offers additional features like improved durability or enhanced aesthetics.

4. Customisation: Aftermarket keys often offer customisation options that may not be available with OEM keys. From key fob designs to colour choices, car owners can add a personal touch to their keys.


1. Quality Concerns: One of the primary drawbacks of aftermarket car keys is the varying quality. While some manufacturers produce keys of comparable quality to OEM keys, others may compromise on materials and craftsmanship. This can lead to issues such as premature wear or malfunction.

2. Compatibility Challenges: Aftermarket keys may not always be compatible with the sophisticated security systems of certain vehicles. This can result in programming difficulties or, in some cases, the key not functioning as intended.

3. Limited Warranty: OEM keys typically come with a warranty from the car manufacturer. Aftermarket keys, however, may have limited or no warranty coverage. This lack of warranty can be a concern if the key encounters problems shortly after purchase.

4. Security Risks: The security of your vehicle could be at risk with some aftermarket keys. Subpar materials and manufacturing processes may make these keys more susceptible to hacking or unauthorised duplication, compromising the safety of your car.

5. Lack of Consistency: Due to the variety of manufacturers producing aftermarket keys, there is a lack of consistency in quality and compatibility. It can be challenging to predict the performance of an aftermarket key without thorough research and verification.


Choosing between OEM and aftermarket car keys is a decision that requires careful consideration. At 247 Auto Locksmith, we recognise the importance of providing options that cater to our customers’ needs. While aftermarket keys offer cost-effective solutions and customisation, weighing these benefits against potential quality and security concerns is crucial. As we operate in Surrey, Sussex, South London, and parts of Kent, our team is committed to providing expert advice and reliable services, ensuring that your choice aligns with the highest safety and performance standards for your vehicle.
