Do you mean Key or immobiliser remote (plipper)? If the key, then I can't think of anything that would cause that.
Using the remote, if you arm the alarm you should hear a relay click, if you cannot hear it then in the first instance change the battery.
If the other remote is working then odds on it is the battery, however if needs be you can buy a new remote but they will need re-programming by someone with the appropriate ODB2 software
