In an effort to save money, many car owners turn to online marketplaces like Amazon and eBay to purchase replacement car keys. While this can sometimes be a cost-effective solution, one of the most common mistakes people make is purchasing the wrong key. Just because a key looks the same does not mean it will work with your vehicle.

Why the Right Part Number and FCC ID Matter

Every car key contains an FCC ID and part number that is specific to your vehicle’s make, model, and year. These numbers help locksmiths and dealerships determine whether the key is compatible with your vehicle’s immobilizer system.

If the FCC ID and part number do not match your car’s OEM specifications, the key cannot be programmed or cut, rendering it useless. It is important to note that many keys share the same FCC ID but have different part numbers, meaning they are not interchangeable. You must verify both the FCC ID and part number before purchasing.

Common Issues With Buying a Car Key Online

When purchasing a key online, many buyers assume that a listing stating “compatible with [car make/model]” means it will work for their vehicle. However, this is often misleading because:

• Many different keys look the same but function differently.
• Even within the same make and model, different trim levels or production years may use different keys.
• Aftermarket keys may not have the correct chip or programming capability.
• Some sellers do not list the FCC ID or part number, making verification difficult.
• Quality of third-party keys may be lower than OEM keys, leading to durability issues.

How to Ensure You Buy the Right Key

Before purchasing a car key online, follow these steps to avoid wasting money:

1. Locate Your Current Key’s FCC ID and Part Number
   • If you have an existing key, check the back or inside of the key for a stamped or printed FCC ID and part number.
   • The OEM part number may be found in your car manual, on the manufacturer’s website, or by calling your dealership.
2. Call a Locksmith or Dealership to Verify Compatibility
   • A professional locksmith or dealership can tell you the exact FCC ID and part number you need.
   • Provide them with your vehicle year, make, model, and VIN (Vehicle Identification Number) for an accurate match.
3. Only Buy From Reputable Sellers Who Provide FCC ID and Part Numbers
   • Avoid sellers who list vague compatibility (e.g., “fits Toyota Camry” instead of “FCC ID: HYQ14FBA, Part Number: 89070-06231”).
   • Check reviews to see if other buyers had success programming the key.
   • Be cautious of cheap aftermarket keys that may not be durable or reliable.

What Happens If You Buy the Wrong Key?

If the wrong key is purchased, a locksmith cannot program or cut it to work with your car. This can result in:

• Additional costs for reordering the correct key.
• Wasted time trying to program a key that isn’t compatible.
• Frustration when you need a working key fast.
• A key that may work initially but fail prematurely due to poor quality materials.

Should You Buy a Car Key Online or Directly From a Locksmith?

While some online purchases may work out, buying from a certified locksmith or dealership guarantees that you are getting the correct key for your vehicle. Many locksmiths offer:

• OEM or high-quality aftermarket keys that are tested for compatibility.
• Cutting and programming services in one visit, saving you time and hassle.
• Expert advice on which key works best for your vehicle.

Final Thoughts

Buying a car key online can be a money-saver, but only if you verify both the FCC ID and part number first. Additionally, the quality of aftermarket keys may not match that of OEM keys, leading to potential issues in the future. To avoid unnecessary frustration, always consult a locksmith or dealership before purchasing a key.
