2011 Cadillac DTS

Remote / key fob programming

This remote can't be programmed with a do-it-yourself procedure. The vehicle needs a diagnostic tool connected to its OBD port to pair a new remote, so a replacement has to be set up by an automotive locksmith or a dealer.

Order the correct replacement remote below — match the FCC ID on your current fob first — then have a local automotive locksmith or the dealer program it to your vehicle.

Photos show the OEM part for each number listed. Aftermarket replacements sold online are often slightly different in appearance — the FCC ID, not the shape, is what determines whether a fob will work with your car.

Cadillac DTS key fob battery

Your Cadillac DTS key fob uses a CR2032 3V lithium coin cell. A fresh one typically lasts 3–5 years.

How to replace the battery

  1. 1 Find the seam or small slot on the edge of the remote.
  2. 2 Twist a coin or small flathead in the slot to split the case open.
  3. 3 Remove the old coin cell and note the + side.
  4. 4 Fit the new battery with the + side matching, then close the case.
  5. 5 Press a button to confirm the LED lights, then test at the car.

Battery tips

  • Use a fresh, name-brand 3V lithium cell — bargain cells drain quickly.
  • Try not to touch both faces of the new battery; skin oils shorten its life.
  • If the remote still doesn't work after a new battery, it may need re-syncing or programming.
