Remote Control Door Locks

Particularly since the MK2 is a four door sedan (saloon) I want to add the modern convenience of centrally operated electric door locks and while I am at it I might as well add a keyless entry feature.

These kits are quite inexpensive and I purchased mine from A1 Electric. https://www.a1electric.com/Merchant2/merchant.mvc?Screen=PROD&Store_Code=AEOS&Product_Code=W02F-712T This kit includes most everything that is needed. The locking part of the kit is advertised as being Swiss made.

This is an image of the contents of the kit:

W02F MES Central Door Locking Kit with Keyless Entry

This image illustrates the dimensions of one of the actuators:

These are the installation instructions provided with the kit:W01F & W02F MES Central Door Locking Kit Installation Instructions

Mounting the Actuators to the Rear Doors

I began the installation of the four lock actuators with the RH rear door. Because the door window and lock hardware were not mounted to the door, I first installed these components. I did so to be sure that the actuator did not conflict with the operation of the window. Information on the installation of the window and lock components is provided in the “Door Handles and Locks” website entry http://valvechatter.us/?p=6027 and the “Doors and Windows” website entry http://valvechatter.us/?p=5485

The kit incorporates mounting hardware including a yellow zinc bendable strap and the necessary screws. These images show the location of the rear door actuators (both doors are the same).

It was necessary to drill three holes in the door: two for the strap and one for the actuator body.

Connecting the Actuators to the Rear Door Locks

Connecting the actuator to the door lock is not difficult, but it is a little complicated to explain. The schematic diagram provided in the Service Manual on page 450 N.24 is helpful.

While most of the mechanism for the front and rear door are the same, there are some distinctions. The rear door components are shown in the small enclosed box in the diagram above. The connecting link (E) with a spring in the diagram is for the front door and the connecting link (Ea), without a spring, shown in the box is for the rear doors.

Lock Connecting Links Front and Rear

The link on the left side of the image above is for the rear doors, the right link is for the front doors. These connecting links do what their name implies: they connect the door handle locking mechanism and the remote control to the door lock and striker plate.

I use the connecting links for both front and rear doors to connect the actuator rod, supplied in the kit, to the car’s locking mechanism. This is accomplished through the use of a small rod clamp that is provided in the kit.

Actuator Rod Clamp

The clamp has two set screws – one to attach the block to the connecting link (The factory lock rod in the diagram) and the other to connect to the actuator’s rod.

Actuator, Actuator rod and Rod Clamp

For the rear doors, to facilitate connection of the components without interference with the window frame, I chose to disconnect the connector link at the dowel (F) shown in the diagram at the top of the page. This will mean that the rear doors will not be locked and unlocked using the door handles which is of no matter to me since the actuators will be doing the job.

I then straighten the connecting link (removed the bends) and used it for the new connection to the connector block. To make the connection, the Actuator Rod needed to be bent slightly.

After installing the actuators in both rear doors, I tested them with a power source and was satisfied that they both operated effectively.

Mounting the Actuators to the Front Doors

Because the door window and lock hardware were not mounted to the door, I first installed these components. I did so to be sure that the actuator did not conflict with the operation of the window. Information on the installation of the window and lock components is provided in the “Door Handles and Locks” website entry http://valvechatter.us/?p=6027 and the “Doors and Windows” website entry http://valvechatter.us/?p=5485

The front doors are a bit more of a challenge when contrasted with the rear doors.

To keep the actuator in a vertical position, I decided to open a hole in the door interior face. The hole can be seen in the following image:

As with the rear door actuators, the front actuators are mounted to the door with two, kit provided,  1″ self tapping screws.

Connecting the Actuators to the Front Door Locks

Unlike the rear doors, I want to use the interior door handle to activate the lock/unlock mechanical mechanism so I kept the original connecting link secured to the lever on the dowel on the door lock (F) in the schematic above.  The spring on the front connecting  link gets in the way of the mounting for the rod clamp, so for the front doors I turned the connecting links upside down. As suggested in the Service Manual I mounted the connecting link in the center position.
