There would be another way to go around this, which i have done before, if anyone has upgraded there alarm to Clifford or Toad etc and use the Alarm buttons to open and close the door, what i did was glue the transponder to the ignition barrel which permantly knocks out the standard imobilisor (which i didn't need as the alarm has one built in) another reason i had to do this was for the remote start as well.
Food for thought.
