Hello

1st check if the little red LED light is coming on the key fob when you push a button

if its not then try another fob battery

if thats OK then I'm sorry to say that a dealer or Caddy specialist will need to be involved to re-code the key to the car

and this involves plugging a diagnostic device into the car to perform this task
