Car Key Fob Keyless Entry Remote fits Ford, Lincoln

USARemote's 4-button replacement key fob (CWTWB1U793) is a fully assembled, user-programmable remote designed to replace your factory Ford, Lincoln, Mercury, or Mazda keyless entry fob.

If your original remote is lost, damaged, or the buttons are unresponsive, this ready-to-program replacement delivers the same four-button functionality (lock, unlock, trunk, panic) and arrives with the battery already installed. It’s sold as a complete electronic assembly so you skip soldering or parts-swapping and can restore remote entry quickly. The fob is built to fit the OEM socket and is an exact match for common part number CWTWB1U793, and USARemote supports the programming process so you can get back to hands-free access with minimal hassle.

Which vehicles will this key fob work with?

This remote is compatible with many Ford, Lincoln, Mercury, and Mazda vehicles that use the CWTWB1U793 style 4-button keyless entry module. Compatibility depends on the vehicle’s model year and original factory remote type, so double-check your car’s part number or existing fob before ordering.
