MechanMagic Key Fob Replacement for Ford (CWTWB1U793) — 2-Pack Pre-tested Pre-programmed Remotes

MechanMagic's replacement key fob is a fully assembled, pre-tested two-pack remote that replaces FCC ID CWTWB1U793 for many Ford and Mercury keyed-ignition vehicles from 2001–2017.

If your original Ford or Mercury remote is lost, damaged, or no longer working, this MechanMagic replacement delivers a budget-friendly way to restore keyless entry and immobilizer functionality. Each remote arrives with batteries, electronics, and the transponder chip already installed; only the metal key blade needs cutting to match your vehicle. The item is intended for vehicles with a traditional keyed ignition and will not work with push-button start or models that use a plastic ignition guard.

How do I install and program the replacement key fob?

Each remote is delivered ready with electronics and a programmed transponder chip installed; the metal key blade must be cut to match your ignition. Programming steps depend on whether you already have working original keys, and we supply self-programming guidance with every order.

• Key blade: must be cut by a locksmith or automotive key cutter to your vehicle’s ignition code.
• Self-programming: instructions and links included; two working original keys are usually required for on-vehicle programming.
• No working originals? A professional locksmith or dealership may be required to program the remote.
• All remotes are pre-tested before shipping to ensure electronics and battery function.

What limitations or vehicle features prevent compatibility?

• Will not work on ignitions protected by a plastic guard that changes key access.
• If unsure about your vehicle’s ignition type, verify before ordering to avoid returns.
• Check the product’s vehicle fitment list for precise model/year coverage.
