A stock FD RX-7 does not come with keyless entry. A factory keyless entry kit was released in Japan for RHD cars but it is not directly compatible with LHD FDs. Several people have reported adapting this kit to work with LHD FDs but details were always sketchy. So I figured I’d give a step-by-step guide for adapting this RHD keyless entry kit to work with LHD cars.
TL;DR: the RHD keyless entry kit can be adapted to work with LHD cars but requires: (1) purchase of an RHD passenger actuator-driven lock, (2) doing some electrical harness rewiring (easy), and (3) modifying the RHD passenger lock actuator to work with the kit (not so easy).
RHD Keyless Entry Kit
The RHD keyless entry kit provides a driver-side actuator-based door lock assembly plus some electrical components and harnesses to drive the actuator. Oddly, all stock FDs (either LHD or RHD) come with a passenger actuator already (which is driven by the manual locking and unlocking of the driver door). The keyless kit works in tandem with the existing passenger actuator to effectively provide keyless locking and unlocking for both doors simultaneously.
As far as I know, the FD RHD keyless entry kit was released only in Japan. Certainly, the kit I received only had Japanese instructions. However, it is widely available outside Japan and can frequently be found on eBay or can be ordered directly from Japan. Its part number is F138-V7-600A and it generally sells for a fairly steep $500 or so.
The kit comes with the following main components: (1) an RHD driver-side actuator-based door lock, (2) a remote receiver, (3) an adapter harness for this receiver that wires it up to the stock factory wiring in the driver-side door, (4) a replacement timer unit that replaces the timing unit on stock cars, (5) an adapter harness to attach this timing unit to the stock factory wiring, and (6) a remote key fob. Step-by-step instructions and a detailed wiring diagram are also provided (in Japanese).
Here are the electronic components that come with the kit.
The timing unit with its adapter harness attached is at the right of the picture. The remote receiver is in the center of the picture, also with its attached adapter harness. To its left is an antenna cable, which plugs into the remote receiver. The remote key fob is at the top middle of the picture and to its left are various Zip Ties and bits and pieces for installing the components
This kit is essentially plug-and-play for RHD cars. Basically, the stock manual driver-side door lock is first replaced with the kit’s actuator-based lock; then the kit’s remote receiver is plugged directly into the factory driver-side door harness using the supplied adapter harnesses; finally, the stock timing unit in the driver footwell is replaced with the kit’s timing unit.
For a variety of reasons the kit will not work directly on LHD cars.
Before discussing these reasons, I will give quick overview of stock LHD door lock circuit and then describe the RHD keyless entry circuit.
Stock LHD Door Lock Wiring
The stock door lock circuit on an LHD FD is pretty simple.
