Replacement remote for Smart Fortwo

This replacement remote key operates at 315 MHz and uses a PCF7941 chip for 2008 to 2015 Smart Fortwo models. It features four buttons and includes a CR2032 lithium battery. The unit matches part numbers KR55WK45144, 267T-5WK45144 and TA-2007/080. It is a non-OEM product supplied new.

315 MHz frequency and PCF7941 chip

The single specification that determines fit is the 315 MHz operating frequency combined with the PCF7941 transponder chip. Your existing remote must use this exact frequency and chip type for the replacement to function. Verify the part numbers on your current key fob against the listed references before ordering.

Requires professional programming and key cutting

This remote arrives with the battery installed but must be programmed and the mechanical key blade cut by a qualified locksmith or dealership. It does not work out of the box. Buyers who cannot access programming services or who need a fully pre-coded unit cannot use this product. Ensure your vehicle accepts aftermarket remote programming before purchase.

Questions about this item

What does the 315 MHz frequency mean for daily use?

It is the radio band the fob uses to talk to the car; the signal reaches the vehicle at normal key-fob range so you can lock and unlock from beside the car.

How does the PCF7941 chip affect programming?

The chip stores the rolling code the car expects; a locksmith or dealer must pair that code to your Smart Fortwo before the remote will work.

What physical space does the CR2032 battery need?

A standard CR2032 coin cell fits inside the four-button fob housing; the battery is included so the remote is ready once the key blade is cut.
