Security Light Blinks Constantly
Ever since I needed a jump start, the security light flashes whenever the car is not running, whether it is locked or unlocked. I thought the security light only flashed after the car alarm has been armed. What is wrong?
Does locking the car with the key (not the fob button) arm the alarm? I can't test this since my light blinks whenever the car is not running.

Found out from service dep't at dealership that the car alarm is armed no matter what method you use to lock the car, i.e. fob button or key in lock.
Regarding the flashing security light, the pitifully inadequate RX 350 owner's manual says "the indicator light changes from being on to flashing when the alarm is set." I got the impression from this that the light is not supposed to flash unless the alarm is armed.

Its not that the alarm is set (that you need to do via the key or door switch) but the disabling device is set after your key is removed form the ignition.

^I have to that procedure every time I disconnect my battery, or else the alarm will go off at random times. Like if I lock the door from the inside and shut the door.

The procedure on the RX300, is to insert all the key fobs you have into the ignition cylinder one by one for about 5 secs each, then exit the vehicle and lock it with the key (not using the keyless entry).

Congratulations! Now you have programmed the glove box light!
