The double locking feature is only avaliable on the Levin ZR and Ultima Models, and unless the windows have been tinted, both front door windows have a label "Toyota Auto Alarm with Double Locking" to indicate that this feature is present. This feature works in conjunction with the smart entry and start system and to activate the double lock, there is a small black "lock" button next to the front door keyhole which you press once to lock, and a second time within 5 seconds to activate the double lock function. The function can also be performed by the same method using the smart entry and start key/remote. The system buzzer also "beeps" once to indicate lock and twice to unlock. All Corolla models however have the indicator flash once (lock) and twice (unlock) for the remote central locking, which the function can be customised i believe, check towards the back of the owners manual.
Yes so with ascent since its just the normal key not the smart entry I do not have this feature. I believe the alarm system sold by the dealer is an aftermarket not sure if its toyota. Did anyone manage to get a toyota alarm system for the ascent with the double locking? I have seen in some forums people buying it and installing it but not sure which toyota alarm. Another way is to get the sticker and put it on the windows to deter ppl from breaking-in as it did happen with the previous car .
