Description

The Vornec Replacement Key Fob for Cadillac is a reliable solution for replacing a lost, broken, or damaged remote. Built to match OEM specifications, this 5-button keyless entry remote provides the same core functions as the original: lock, unlock, trunk release (sedan), remote start, and panic. It also includes a blank uncut emergency blade that must be cut to fit your vehicle.
Important: This is a replacement remote. It requires professional programming by a qualified automotive locksmith or dealership before it will operate. The emergency blade must be cut to your vehicle.
Compatibility Note: Please confirm your vehicle's FCC ID and Part Number with your original remote before purchasing. If you are not sure, provide your VIN to a dealership or qualified locksmith and they can confirm the correct key fob model for your vehicle. Ordering by VIN helps ensure a perfect match and prevents returns.
