OEM Cadillac CTS STS Smart Key Fob Remote - 433 MHz, M3N5WY7777A (Replaces 25943679)

Need a spare or replacement smart key for your Cadillac CTS or STS?

This is a brand new, OEM key fob.

It came in a bulk order, so it's sealed and protected but not in the original retail packaging.

The important stuff is all there: it's the real deal.

The frequency is 433 MHz (non-US market), with FCC ID M3N5WY7777A and IC 267F-5WY7777A.

It replaces part numbers 25943679, 25854940, and 15864388.

It has a Philips 46 chip inside.

If your current fob is worn out or you just want a backup, having a fresh, genuine one is the way to go.
