2009 Cadillac SRX
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.
Replacement key fobs
Find your key type below, then match the FCC ID printed on the back of your existing fob — or, for a plain transponder key, the blank code — to be sure of the right part.

Cadillac SRX key fob battery
Your Cadillac SRX key fob uses a CR2032 3V lithium coin cell. A fresh one typically lasts 3–5 years.
Buy Energizer CR2032 Lithium Coin Batteries (4-pack) on AmazonHow to replace the battery
- 1 Find the seam or small slot on the edge of the remote.
- 2 Twist a coin or small flathead in the slot to split the case open.
- 3 Remove the old coin cell and note the + side.
- 4 Fit the new battery with the + side matching, then close the case.
- 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.
