9 reviews for 2004-2006 Mazda 3 Sedan 3-Button Key Fob Remote (FCC: KPU41846, P/N: BN8P-67-5RY)

  1. Steveo (verified owner) –

    Love it. Unit works perfectly. Was amazed at how easy it was to program this remote to to the car.

  2. Jane (verified owner) –

    Lost one of my fobs and was shocked at the price from the dealer. I did feel like an idiot opening and closing the door but it has worked for over a year now with no battery change. Great find.

  3. Daniel (verified owner) –

    I had difficulty programming the remote with the instructions provided. I was able to find alternate instructions online that did work. Once programed, I had an issue with the remote, where the lock and panic button functions were reversed. For example pressing the lock button would activate panic mode, and pressing panic button would activate the door locks. My initial thought was, oh well I saved and can deal with the swap of buttons. After thinking it over a bit, I decided to look at the inside of the remote, and noticed the circuit board inside appeared upside-down. I separated the board from the rubber backing, flipped the board around and reassembled the remote. Everything worked as it should after flipping the circuit board around. I gave 4 stars to this because aside from poor instructions and an improperly installed circuit board, this remote does exactly what it’s supposed to, looks OEM, feels quality enough and is a good price.

  4. Denise (verified owner) –

    This is a great small business to support. Excellent quality products, low, low prices, and stellar customer service.
    I am so glad that I found NorthCoast Keyless online. I saved almost $200!

  5. Matt Gaffney (verified owner) –

    I had purchased prior from another sellar and none of them would work with my son’s car. I came across this site and took a chance on it. received the fob went to his car performed the programming action and on the very first try it worked. Done !!! Great Site and excellent documentation.

  6. Anonymous (verified owner) –

    Works great and was very easy to program.

  7. Eileen (verified owner) –

    Was so easy to program. Would highly recommend this company.

  8. Aaron (verified owner) –

    The FOB itself works well and was reasonably priced.

    The programming instructions were very close, but had one crucial error that caused difficulty with my ’06 Mazda 3. The instructions indicate to remove the key from the ignition upon turning to the ON position 3 times (Step 4b). This was incorrect – the key must remain in the ignition or the vehicle will never enter programming mode. Alternate instructions online highlight this and it made all the difference. After that hiccup was resolved, it programmed easily and so far is working very well.

  9. Denise (verified owner) –

    NorthCoast Keyless is one of the best companies that I have dealt with. I have bought two remotes for my car and I saved well over $400. NorthCoast responds quickly to emails and is there to help if you have a question. And, of course, the product is superb. I shall never buy from a dealership again. Cheers, Denise

Before Ordering

Every key fob sold includes the following:

  1. Key fob remote as described in the product listing
  2. New battery installed
  3. Uncut emergency key (if applicable)
  4. All key fobs are tested 3X before shipment
  5. 100% customer satisfaction money back guarantee

Simply search for your Make/Model/Year on our website (ex. - "2009 Ford F150"). It’s important to get the correct remote for your vehicle. You can do this two ways:

  1. Check an existing remote - Just check the back or inside of an existing fob. ALWAYS get the same button configuration.
  2. Check the VIN - If you do not have an existing fob, call a Dealership with your VIN to get the Part Number you need.

If you have any questions, feel free to contact us at [email protected].

Hold tight!  We are getting new stock in every day. Simply sign up for the Waitlist on the correct product's page and you'll be immediately notified when it comes back in stock.

We will help ensure that you get the correct remote for your vehicle or make any modifications to your order! Just reach out to our support email [email protected].

For many vehicles, yes! It's easy and anyone can do it! Check out our Free Programming Instructions for easy step-by-step instructions to program your remote.  If your vehicle requires professional programming we let you know on each vehicle specific programming instruction page, so you're not left with any doubt and searching all over the internet.  We recommend that you use our Auto Locksmith finder to have a Locksmith come to you and program the remote for cheaper than a Dealership: Auto Locksmith Finder.

We STRONGLY recommend that you call a local Automotive Locksmith for this service.  Locksmiths are generally more helpful, skilled at remote programming, won't refuse service and are more reasonably priced than Dealerships for remote programming.
You can find an Auto Locksmith near you with our Auto Locksmith Finder.

Yes! We ONLY sell "OEM" - original factory/manufacturer electronic key fob remotes.  Just like those from your local Dealer but for about 70% less, saving you from the Dealership markup.

Of course! We only sell OEM quality key fobs in a few different conditions:

  1. Factory Sealed - These are genuine OEM, factory sealed key fobs.
  2. New, Never Programmed OEM - These are Genuine OEM, new, never programmed fobs. They are bulk packaged and not in a factory sealed bag.
  3. Lightly Used, OEM Refurbished - This is a lightly used, Grade A, refurbished OEM fob. They have been professionally cleared and are ready to program to your vehicle, with a new battery installed and uncut emergency key included (if applicable).
  4. OEM Electronic - These consist of an OEM Circuit Board with an Aftermarket Shell (No Logos), with a new battery installed and uncut emergency key included (if applicable).

If you have any questions, feel free to contact us at [email protected].

OEM - These products are manufactured by the Original Equipment Manufacturer.  Meaning this is the same product that you can purchase at the Dealership.  These products are high quality and superior to "replacement" remotes being sold on the internet.

  • David Wahnon (verified owner) –

    Excellent replacement for my 2016 Mazda CX5. Had a local auto locksmith cut the key and program it. Works perfectly. Saved several hundred dollars. Shipped fast as well.

  • w –

    As described and works perfectly with programming.

  • James Jaramillo (verified owner) –

    2016 Mazda 6 OEM Key Fob worked like a charm! Do yourself a favor and order your key here instead of Amazon. I had issues with the aftermarket Amazon keys and my locksmith couldn’t get the Amazon keys programmed. I ordered this one and was seamless!

  • Mel –

    Easy programming. Worked on first try. This is the third key fob I purchased from different sellers and it was the only one that worked. Thank you

  • Anonymous –

    Everything as advertised. Well done.

  • Robert Nugen (verified owner) –

    Can we put 7 stars?? Fed ex dropped off the key before expected, probably because y’all was on top of it and sent my order out bright and early in the morning. Brand new own key fob and had a good fresh battery in it already. Same day I went and had it programmed. Flawless. Guaranteed if I have key fob problems with any future vehicles or any of my buddies, I’ll send them your way. And the icing on the cake….the email that y’all sent to ask if I was happy with my purchase or if there was anything you needed to do to make things right. That right there, thank you

  • Howard Savage (verified owner) –

    The OEM key fobs were lightly used, as advertised, but once programmed by Mazda, they work perfectly. They even included key blanks, two of which were correct and worked great after cutting.

    Buying these two saved me hundreds of dollars over New OEM key fobs from Mazda.

    The only complaint was regarding delivery and that was due to FedEx. They claimed delivery had taken place three days before they actually arrived. Confusing.

  • Gary W (verified owner) –

    I got the more expensive, new version, and I’m glad I did. Mazda service refuses to even try to program cheap knockoffs, as they often trigger a complete system lockdown on the car, incurring a new $260 programming session. The NorthCoast OEM passed inspection and was successfully programmed without incident. Highly recommended.

  • Tom M. –

    Product was exactly as described and was programmed successfully by a locksmith shop locally. I’m totally satisfied.

  • Mark –

    Ordered a key FOB for my Mazda CX5. It arrived quickly and looked great. Programmed at local dealer without issue. Key cost was MUCH cheaper through NorthCoast as compared to dealer.
