Lock, unlock, and access your Cadillac from a distance with the Standard Ignition Keyless Entry Transmitter (KET133). This key fob sends a radio signal to the vehicle's receiver to operate the remote door locks and other keyless functions, and it installs as a direct-fit OE replacement for the 2012-2013 Cadillac CTS. See the Buyer's Guide tab for engine-level fitment.

  • Direct-fit OE replacement: designed to match the fit, form, and function of the original transmitter for straightforward installation.
  • Built to OE performance: engineered to meet or exceed original-equipment performance so the fob works as intended.
  • Tested to OE specifications: checked against OE specs to help deliver reliable operation and long service life.
  • Quality-controlled build: produced under complete quality control throughout the manufacturing process.

If your original fob is lost, damaged, or no longer responding, this transmitter replaces it. Note that most keyless entry transmitters require programming to the vehicle after installation; consult the vehicle service information for the correct procedure.
