When you lose your car key or need a spare, it might seem like a smart idea to head online and order a replacement. A quick search brings up dozens of cheap options, and it’s easy to assume you’ll save time and money by skipping the locksmith or dealership.
But here’s the reality, buying car keys online is rarely as straightforward as it seems. Many people find themselves with the wrong key, an unprogrammable fob, or a product that simply doesn’t work.
In this guide, we’ll explain where most drivers go wrong, what to watch out for, and why it’s usually safer (and often cheaper in the long run) to call in a professional auto locksmith like Carsmith Midlands.
The promise of cheap online car keys
There’s no shortage of websites offering cheap replacement keys and fobs. Marketplaces like eBay and Amazon are full of listings for “compatible” car keys for all makes and models. Many advertise savings of up to 70% compared to going through a dealership.
It’s tempting, especially if you’re in a hurry or don’t want to pay full price. But this is often where the trouble starts.
Common mistakes people make when buying keys online
1. Assuming every key can be programmed to your car
Not all keys or fobs can be programmed without specialist tools. Many vehicles (especially newer models) require security codes, dealer-level diagnostic equipment or PINs to code the new key to the car’s immobiliser system. If you buy a key online without checking whether it’s programmable to your exact model and year, you could end up with a useless piece of plastic and metal.
2. Buying the wrong key or remote type
Even within the same brand or model, car keys can vary significantly based on trim level or year. A Ford Fiesta from 2012 might use a different frequency or chip than one from 2015. The differences aren’t always visible, so it’s easy to get caught out unless you have technical knowledge.
3. Falling for low-quality or cloned keys
Some cheaper online keys are counterfeit or poorly cloned. They may look right, but the electronics inside are often unreliable. You might find that they work intermittently, lose their signal quickly, or fail completely after a short time.
4. Forgetting about cutting and coding
Even if you get a genuine blank key or remote online, it still needs to be cut and programmed. Most locksmiths will refuse to cut or code customer-supplied keys because of the risks involved. If something goes wrong, the locksmith may be held responsible, even if the issue is with the part itself.
5. No support if something goes wrong
When you buy a key from an online seller, you rarely get follow-up support. If it doesn’t work, the seller may not accept returns, especially if the key has been cut or tampered with. By contrast, a reputable auto locksmith will guarantee their work and resolve any issues on the spot.
