As a Noun: 1. In a vehicle, a device that secures the doors. English = door lock remote. Note: 1. There appears to be no commonly used Auslan sign for DOOR LOCK for most signers (but some signers represent this visually using these depicting signs, once they have established the topic). This suggested sign is a combination of the Auslan sign REMOTE and a depiction of two flat objects moving down or two flat objects clamping back towards the signer. Source of this recommended sign: Victorian College for the Deaf.
