My 2003 lock itself back only if the keyless entry is pressed and no door is open within a minute. It does NOT lock itself when the last door is closed, unlike some alarm system I have seen, that arm themselves after the last door is closed. In the RAV4, at least mine, it will never lock itself once a door is opened. No need to leave a door open. Press the key, open one door, close it again, and the car will not lock itself again.
The whole idea behind the relocking when no door is open is to protect you from unintendely unlocking the car given than the button is on the keychain in your pocket. Prime example, you are working in your office, within range of your car keyless system, the keychain is in your pocket and one of the thousand objects we keep in our pockets press the UNlock button. The car will unlock and you will never know. If the car will not relock itself then you are exposed to have your car open and unlocked to every thief in town. But since the car is expecting you to open a door within a minute, voila, it will lock itself back and you will never know how close you were of losing that precious.
So, think again about getting rid of this. I have seen cars running for hours because their owners forgot to activate the option in the remote starters.
