How to Avoid Cheap Counterfeit Key Fobs Sold Online

As a seasoned car locksmith, I’ve seen my fair share of dodgy key fobs that simply don’t cut the mustard. You’d be amazed at how many times I get called out to help someone who’s bought what they thought was a bargain key fob online, only to find it’s a counterfeit piece of rubbish. Today, let’s delve into how you can steer clear of these low-quality imitations and make sure you’re investing in a key fob that’s not just reliable but also safe for your vehicle.

Understanding Key Fobs

First off, it’s essential to grasp what a key fob does. In simple terms, a key fob is a small remote control device that allows you to unlock your vehicle, start your engine, and often perform other functions, like opening the trunk or immobilising the vehicle. The convenience they offer is undeniable, but with convenience comes some risks—especially in the digital age where counterfeiting has become increasingly sophisticated.

Why Counterfeit Key Fobs Are Dangerous

At first glance, a cheap key fob might seem like a steal—maybe even an opportunity to save a few quid. However, these counterfeits often don’t function properly. A subpar fob can fail to communicate with your car, rendering it useless. Even worse, some counterfeit key fobs could compromise your vehicle’s security system, potentially putting you at risk of theft. You’ve worked hard for your car; the last thing you need is to hand over your vulnerable security to a low-grade knockoff.

Know the Risks of Buying Online

Let’s face it: online shopping is convenient, but it’s a double-edged sword, especially when it comes to car key fobs. The vast array of options can lead you down a rabbit hole of choices that aren’t always authentic. If you’re not vigilant, you might unknowingly purchase a counterfeit. The anonymity and lack of physical inspection make it all too easy for rascals to peddle low-quality merchandise.

Check Reputable Sellers

When it comes to buying key fobs, the first rule of thumb is to purchase from reputable sellers. This might be an authorised dealership, a certified locksmith, or a well-established online retailer. Keep an eye out for customer reviews and ratings; these are invaluable. Look for feedback that specifically mentions the key fob’s functionality and compatibility with various car models. A few minutes of research can save you a whole heap of trouble.

Be Wary of Prices That Are Too Good to Be True

If you stumble across a key fob priced significantly lower than the average market value, your intuition should set off alarm bells. While occasional sales do crop up, consistently low prices can indicate that you’re dealing with a counterfeit. Quality key fobs cost money to produce, so if a deal feels like it’s straight out of a ‘too good to be true’ catalogue, it probably is.

Understanding Compatibility

Before you even think about hitting that "buy" button, ensure you know your vehicle’s key fob compatibility. Check your owner’s manual or consult the manufacturer’s website for the correct part number. Then, cross-reference that with the seller’s listing. If a seller can’t provide this information or leaves it vague, it’s a red flag. A legitimate seller will always have accurate details about the fob they are selling and how it aligns with various vehicle models.

Inspect the Product Listing

Let’s talk about the product listing itself. A genuine seller will typically have multiple high-quality images of the key fob from various angles. Check if they also highlight features like buttons, logos, and unique markings. If the listing contains generic images or poorly lit pictures, it’s a sign that they might be trying to hide something—namely, the fact that the fob you’re looking at isn’t the genuine article.

Check for Security Features

Modern key fobs come with a range of security features designed to protect your vehicle. Original equipment manufacturer (OEM) fobs often incorporate chips that communicate with your vehicle’s onboard computer. Consequently, this can make counterfeit versions much less effective. If a seller can’t confirm whether the key fob has the necessary encryption or coding for your specific vehicle make and model, step back. Avoid risking both your wallet and your car’s security.

Understand the Return Policy

Before clicking ‘purchase’, scrutinise the return policy. A reputable seller will have clear policies in place, including how to return a faulty product. If a seller makes it difficult to understand or seems evasive about returns, it’s best to put that fob back and look elsewhere. The assurance of a solid return policy indicates confidence in the product, which you should expect from reliable sellers.

Ask for Assistance

Never hesitate to reach out to your local car locksmith if you’re unsure about a fob you’re considering. We’re often more in touch with what’s going on in the industry than most people realise. An expert can help verify the fob’s compatibility with your vehicle or even guide you in the purchase process to ensure you’re getting a legitimate product.

Be Cautious with Personal Information

When making online purchases, data security is paramount. Make sure the site you’re buying from is secure—look for the small padlock symbol in your browser’s address bar. Ensuring your personal details, including payment information, are safe is crucial. A shady dealer might not only sell you a counterfeit key fob but could also misuse your information. Invest time in choosing a platform where your data is protected.

Beware of Fast Shipping

A killer deal paired with expedited shipping should always raise a red flag. If an online seller is promising miraculous speed for a deal that feels unusually cheap, take a moment to reconsider. Quality items take time to ship appropriately; if it’s coming straight from a factory with low overheads in another country, you could find yourself waiting far more than you expected—even if the initial delivery estimate is swift.

Network with Other Car Owners

Sometimes, word-of-mouth is the best form of marketing. Joining local car enthusiast forums or community groups can provide you invaluable insight into where to find legitimate key fobs. Fellow car owners often share their experiences, including where they purchased their key fobs and their experience with different sellers. Engaging with this community can also provide you with tips on avoiding poor-quality fobs and counterfeits.

Know What a Genuine Fob Looks Like

Familiarise yourself with how your vehicle’s original key fob looks. Check for logos, colour shades, dimensions, and button placements. Counterfeit fobs often have discrepancies that might not be immediately noticeable. By being informed on what a genuine fob embodies, you can more easily spot any counterfeiting tell-tales.

Educate Yourself on Key Programming

Finally, if you do decide to purchase a key fob and are wondering about programming it, be prepared for the potential need for professional assistance. Some key fobs require specific programming tools and knowledge to function correctly. If the seller doesn’t provide clear instructions on how to programme the fob for your car, it can be a signal that the fob you’re eyeing might be of lower quality.


So, as you embark on your quest for a replacement key fob, keep these essential points in mind. Being informed, diligent, and a tad sceptical can make all the difference in ensuring you don’t end up with a subpar product that could jeopardise your vehicle’s security. The car locksmithing world can be a minefield, but arming yourself with knowledge is your best defence against counterfeit key fobs. Your vehicle—and your peace of mind—will surely thank you for it.
