In November my lovely White Pkg #9 began to false alarm at work. I took it to the dealer who indicated he was going to adjust the sensitivity. The problem appeared to be corrected until mid-February at which time the car began to false alarm between 5 and 12 hours after being locked. The only way to stop it (before I was able to go to the dealer) was to leave the car unlocked - not an optimal solution. After a week at the dealers where they eventually resorted to calling Toyota it turns out that they've seen cases of the car false alarming due to faulty front door locks. The locks send an incorrect signal that the car is being broken into. Toyota is aware of the problem and had two FTS's working on my car over the past week. Other symptoms included the locks not being as responsive and having to press the unlock button multiple times to unlock - or the car not responding immediately to use of the door handle. Thought it might help others so they would not have to wait a week to get the problem resolved.
