Authorized parts are components made or approved by the manufacturer of your product, and using them is often required to keep your warranty valid.

When you need to repair something you own — a car, appliance, phone, or piece of equipment — you have choices about which parts go into it. An authorized part is one that the original manufacturer has made themselves or explicitly approved a supplier to make. The manufacturer stands behind it. A non-authorized part (sometimes called aftermarket or third-party) comes from a different company and may or may not work as well or last as long.

The distinction matters because manufacturers use warranty language to require authorized parts for repairs. If you use a non-authorized part and something goes wrong, the manufacturer can refuse to cover the damage under warranty. Understanding what counts as authorized, where to find these parts, and when you actually need them helps you make repairs without accidentally voiding coverage you paid for.

How manufacturers define authorized parts

A manufacturer controls which parts are authorized through their warranty documents and their supply chain. Some manufacturers make all their own parts in their own factories. Others contract with specific suppliers to manufacture parts under their brand or specification. Either way, the manufacturer tests these parts to may support they work correctly with their product and last for a reasonable time.

When you buy a product, the warranty paperwork lists what voids coverage. Most warranties say something like "warranty does not cover damage caused by non-authorized parts" or "repairs must use original manufacturer parts." This language gives the manufacturer legal ground to deny a claim if you used something else. The manufacturer's website usually has a list of authorized parts suppliers, or you can call their customer service to ask whether a specific part is authorized.

The difference between authorized and aftermarket parts

Aftermarket parts are made by companies other than the original manufacturer. They may be identical in function, similar in quality, or significantly cheaper. Some aftermarket parts are excellent; others are poor quality or incompatible. The problem is that you cannot know which is which without research, and the manufacturer will not may provide them.

Authorized parts come with the manufacturer's assurance that they will fit, function correctly, and last for a specified time. If an authorized part fails, you can return it to the manufacturer or the authorized dealer for replacement or refund. With an aftermarket part, you are dealing with a different company that may or may not honor a return, and the original manufacturer will not help you.

When authorized parts are required to keep your warranty

Your warranty terms determine when authorized parts are mandatory. Read your warranty document — it is usually in the box or available on the manufacturer's website. Most warranties require authorized parts for any repair done by an authorized service center. Some warranties allow you to use non-authorized parts for repairs you do yourself, but this varies widely.

If you are unsure, contact the manufacturer before you repair anything. A five-minute phone call can tell you whether using a non-authorized part will void your warranty. Many manufacturers have a customer service number on their website or in your product manual. Be specific: tell them what part you want to replace and ask whether doing so yourself with a non-authorized part will affect your coverage.

Where to buy authorized parts

The easiest place to find authorized parts is the manufacturer's official website. Most manufacturers have a parts store or a link to authorized retailers. You can search by your product model number (usually found on a sticker on the product itself or in your manual) and see exactly which parts are available and their cost.

Authorized dealers — stores or service centers licensed by the manufacturer — also stock authorized parts. For cars, this means dealerships. For appliances, it might be a local service center or a big-box retailer's parts department. For electronics, it might be the manufacturer's own store or authorized resellers. You can find authorized dealers through the manufacturer's website, which usually has a store locator or a list of service centers in your area.

Cost differences and what you are paying for

Authorized parts typically cost 20 to 50 percent more than comparable aftermarket parts, sometimes more. You are paying for several things: the manufacturer's testing and quality control, the may provide that the part will work with your specific product, the ability to return a defective part, and the assurance that using it will not void your warranty.

If your product is still under warranty, this cost difference often makes sense. A $50 authorized part that keeps your $500 warranty intact is a good trade. If your product is out of warranty, the calculation changes. You may decide that the lower cost of an aftermarket part is worth the risk, especially if the part is straightforward and widely available from multiple manufacturers. For complex or critical parts — like a compressor in a refrigerator or a battery in a laptop — many people choose authorized parts even out of warranty because the risk of failure is higher.

Repairs you can do yourself versus authorized service centers

Some repairs are straightforward enough that manufacturers allow you to do them yourself without losing warranty coverage. Replacing a filter, a light bulb, or a battery in a device you own is usually fine. Your warranty document will list what you can do yourself. If it is not listed, assume you need an authorized service center.

For anything more complex — opening the device, replacing internal parts, or working on sealed components — most manufacturers require an authorized service center. This is partly about safety (opening some devices can be dangerous) and partly about ensuring the repair is done correctly. If you do a repair yourself and it causes further damage, the manufacturer can deny all warranty claims related to that damage. Authorized service centers have training, tools, and parts to do the job right, and they carry liability insurance if something goes wrong.

What happens if you use a non-authorized part

Using a non-authorized part does not automatically void your entire warranty. It voids coverage for that specific component and any damage caused by it. If you replace a battery with a non-authorized battery and it fails, the manufacturer will not cover the battery. If the failed battery damages the device itself, the manufacturer may refuse to cover that damage too, depending on their warranty language.

Some manufacturers are stricter than others. A few will void your entire warranty if you use any non-authorized part anywhere in the product. Most will only deny claims directly related to the non-authorized part. Before you use a non-authorized part, read your warranty or call the manufacturer to understand the specific consequence for your product.

Frequently Asked Questions

Can I use an aftermarket part and still keep my warranty?

It depends on your warranty terms and the manufacturer's policy. Some manufacturers allow aftermarket parts for repairs you do yourself, while others void coverage for any non-authorized part. Read your warranty document or call the manufacturer before you buy an aftermarket part. They can tell you exactly what will and will not affect your coverage.

Are authorized parts always better quality than aftermarket parts?

Authorized parts are tested by the manufacturer and may provide to work with your product, but that does not always mean they are higher quality overall. Some aftermarket parts are excellent. The difference is that the manufacturer stands behind authorized parts with a may provide, while aftermarket parts come with whatever may provide the third-party maker offers. For critical parts, this may provide matters more than raw quality.

Where do I find the model number to order the right authorized part?

The model number is usually on a sticker on the product itself — check the back, bottom, or inside. It is also in your product manual or on your receipt. Once you have it, go to the manufacturer's website and search for parts by model number. This ensures you order the part that fits your specific product.

What if an authorized part fails shortly after I install it?

Contact the manufacturer or the authorized dealer where you bought the part. Authorized parts come with a may provide, usually 30 days to one year depending on the part and manufacturer. If it fails within that period, you can return it for a replacement or refund. Keep your receipt and the part packaging to make the return process easier.

Do I have to use an authorized service center, or can I take my product to any repair shop?

Your warranty may require an authorized service center for repairs to stay covered. Check your warranty document to see if it specifies where repairs must be done. If it does and you go to a non-authorized shop, the manufacturer can deny your claim. If your warranty does not specify, you can use any repair shop, but confirm with the manufacturer first that doing so will not affect your coverage.
