MechanMagic Replacement Key Fob CWTWB1U793 for Ford F-150/F-250/F-350 (2-Set) — Pre‑programmed, Battery Included

MechanMagic replacement key fob CWTWB1U793 is a pre-configured, battery-included keyless entry remote that replaces lost or worn Ford/Mercury keyed ignitions (non‑push start) for compatible models.

If your Ford or Mercury uses the FCC ID CWTWB1U793 / OUC6000022 remote and relies on a keyed ignition (not a push‑button start or plastic ignition guard), these two replacement key fobs arrive with installed electronics, a transponder chip and batteries so you can have a working spare or immediate swap. Each fob ships pre-tested; the metal key blade requires cutting and the unit must be programmed to your vehicle. Amazon-style fitment lists and step-by-step self-programming instructions are included with every order to help you confirm compatibility and complete basic setup.

Which vehicles and part numbers does this MechanMagic fob replace?

This replacement is built to match remotes using FCC ID CWTWB1U793 / OUC6000022 and several Ford/Mercury part numbers. It covers a broad set of Ford trucks, SUVs and vans produced in the model years listed in the product title.

• Compatible models include: Ford F-150 (2004–2014), F-250/F-350/F-450 series, Flex, Explorer, Escape, Ranger, Fusion, Econoline, Expedition and Taurus X where specified.
• Also works with Mercury vehicles such as Monterey and Mariner when they use the matching FCC ID and part numbers.
• Replaces part numbers like 164-R8070, 850K-D600022 and related OEM remotes that use the same internals.

How do I program and prepare the spare key fob?

Each remote includes the electronics and a pre-installed transponder chip; the metal key blade is blank and needs cutting before programming. If you have at least two working original key fobs, you can follow self-programming steps provided with your order; otherwise a locksmith or dealer is required.

• Key blade must be cut to match your ignition cylinder prior to programming.
• Self-programming instructions (links included) guide you through the on‑vehicle procedure when two original fobs exist.
• If you lack two working keys, professional programming by a locksmith or dealership will be necessary.

What limitations or vehicle features prevent this fob from working?

This MechanMagic remote is intended for vehicles with a traditional keyed ignition and without a plastic ignition guard; it is not compatible with push‑button start or proximity smart key systems. Confirm your vehicle’s ignition type before purchase.

• Will not work on vehicles equipped with a push‑button start (smart/proximity keys).
• Incompatible with ignitions that have a plastic guard or housing that prevents key insertion.
• Always verify FCC ID and part number match before attempting programming.

What comes in the box and what should I expect during installation?

Two fully assembled key fobs arrive with batteries and electronics already installed. You’ll receive the remotes, transponder chips, and documentation; expect to have the metal keys cut and then follow the programming instructions or visit a pro for final synchronization.

• Contents: 2 x keyless entry remote controls with electronics, transponder chips, and batteries.
• Documentation includes fitment guidance and self-programming instruction links to simplify setup.
• Installation steps: cut key blades, test fit, then perform programming sequence or use locksmith services if needed.

Who is this for? MechanMagic’s CWTWB1U793 replacement key fob set is designed for owners of compatible Ford and Mercury models who need a direct replacement or spare for a keyed‑ignition vehicle. It suits DIYers comfortable with key cutting and follow‑along programming instructions, as well as drivers who prefer to bring a ready‑tested remote to a locksmith or dealer for professional programming. If your vehicle uses a push‑button start or has an ignition guard, choose a model specifically made for proximity or guarded ignitions instead.
