They will then work in the doors. I think you'll have to have a dealer or locksmith program at least on of the keys. there are plenty of YouTube videos about the procedure for programming the vehicle to recognize the keys. Contrary to how it sounds, you're not actually programming the keys. Each key has an RFID (Radio Frequency Identifier) chip in it that transmits it's unique identification number when it is placed in an appropriate energy field (it's generally in the steering column and/or the ignition lock housing). If the number matches one which the body controller recognizes, it will allow the vehicle to start & run the engine so it can be driven, otherwise it won't and the vehicle is not drivable. What you are doing is telling the body controller to remember the transponder code from a given key's RFID chip as a legitimate key so the vehicle can be driven. The remote door lock controllers work similarly - the instructions for programming the remotes can be found in the owner's manual for your specific vehicle. Sorry I could not be more helpful. **Q: I have an original key and one I had programed by the dealer will they work for duplicating a new chip key** A: As long as you have 2 working keys you can program the new keys. **Q: Will these also work on a 2010 F150 from Canada?** A: I can't see why they wouldn't. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great value *by B***H on February 26, 2026* Worked perfect ### ⭐⭐⭐⭐⭐ Cheaper than the stealership. *by B***Y on January 4, 2026* They work like they should. Had them cut at my local hardware store and being a retired Ford technician, I programmed them myself . ### ⭐⭐⭐⭐⭐ Easy as one two three & done by me! *by T***E on April 16, 2025* It works perfect! Heads up folks, you do not need a locksmith for this. I called the Ford house they will cut the key for you for next to nothing or even free. Then I followed the directions that this seller provides and it was simple easy quick as one two three. That is if you already have two original programed keys for your car. Sick key one of the originals in & turn to on then right back off, repeat with the second original, then immediately with the new key that's to be programed sept go ahead & start the engine. Ps don't hesitate in-between the keys. Yep, it's that simple and locksmiths are charging $200 to program the key alone. That's ridiculous. Absolutely atrocious.... ## Frequently Bought Together - KeylessOption Car Key Replacement for 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 Ford Lincoln Mazda Mercury Ignition Transponder, H84 H92 40 80 Bit - 2 Pack - SUPALAND Key Fob Keyless Entry Fits for Ford F150 F250 F350 Explorer Expedition 1998-2016 / Ranger Escape Edge E150 Freestar / Lincoln Navigator Mazda 3 Button Remote Control Replacement CWTWB1U345 - Vurkcy Keyless Entry Remote Key Fob Compatible with Ford Escape Explorer Expedition Focus Fusion Mustang Taurus, Lincoln, Mercury, Mazda, Replacement for CWTWB1U345, 4 Button (Pack of 2) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/3886580-car-key-replacement-for-2000-2001-2002-2003-2004-2005](https://www.desertcart.co.uk/products/3886580-car-key-replacement-for-2000-2001-2002-2003-2004-2005) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
