Description of the Related Art Conventionally, in a door lock operating device in which a door lock is locked and unlocked by remote control using a transmitter capable of transmitting radio waves and the like, a signal is transmitted by locking and unlocking the transmitter. When the code signal matches a preset coat signal on the receiver side provided on the vehicle body side, the door lock can be locked or unlocked. Therefore, if the locking operation is performed from outside the vehicle using the transmitter with the key inserted in the ignition key cylinder for starting the engine, the key will be locked with the key inserted in the ignition key cylinder and you will not notice it When the vehicle is away from the vehicle, there is a problem that an undesirable situation occurs in the antitheft property.

[0003]

The above-mentioned problem can be solved by disabling remote control by a transmitter when a key is inserted into an ignition key cylinder. If the key is inserted into the ignition key cylinder and the door is locked in the operation of locking from outside the vehicle without using the transmitter, the key is inserted in the ignition key cylinder and the transmitter is locked. Operation becomes impossible, the key is sealed in the vehicle, and there is a possibility that the operability is reduced. SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems of the related art, and has been made in consideration of the above-described problems, and is intended to prevent a key from being enclosed in a vehicle, thereby improving the antitheft property and operability of an automobile door lock. It is intended to provide a device.

[0004]

To achieve the above object, the present invention provides a door lock having a meshing mechanism capable of engaging and disengaging a striker, and a locked state in which a release operation of a door opening operation means is invalidated. Locking and unlocking means that can be switched to an unlocked state to be enabled, a transmitter that can remotely operate the locking and unlocking means in a locked state or an unlocked state, and an ignition switch that detects a key insertion state in an ignition key cylinder. An operation device for a vehicle door lock having a feature that, when an ignition switch detects a key insertion state, a locking means by a transmitter is invalidated and a discriminating means for enabling an unlocking operation is provided. And

[0005]

When the key is inserted into the ignition key cylinder, the ignition switch detects the key insertion, and the locking / unlocking means is in the unlocked state, even if the transmitter is locked, the locking operation is determined by the determination means. And the locking / unlocking means cannot be locked. Therefore, with the key inserted in the ignition key cylinder,
The locking operation of the door lock can be prevented.

[0006] Further, if the locking and unlocking means is in a locked state by a locking operation such as a keyless locking operation from the outside of the vehicle with the key inserted in the ignition key cylinder, the operation is performed by unlocking the transmitter. The validity is determined by the determination means, and the locking / unlocking means can be in the unlocked state.
