Long story short the ignition barrel on my rover was keyed in such a way that the key had a very deep cut near the head. This caused me to break keys like you would believe and eventually the inevitable happened, a key broke inside the barrel. I have since removed the barrel and replaced the switch with a set of relays being controlled by a micro controller.

What I want to do now is incorporate more systems into my micro controller so that I can control things like windows door looks, turn the alarm on and off(key fob has long since been MIA). I have not been able to find a wiring diagram for the remote receiver and tying into those lines would be optimal so if you know where I could find one I would appreciate it greatly. Also if anyone has any insider tips or advice I would appreciate it greatly.

Current Features:
4 inch touch screen interface.
Password protected(PIN).
Single press engine start and stop.

Future Features:
Android Remote app and or 4 button remote keyfob.
RFID tag password override
Window controls via remote and TS
lock controls via remote and TS
alarm on/off controls via remote

Maybes:
ODBII integration
Light controls

If there is anyone with experience in interfacing aftermarket remote systems any and all advice is welcome. Thanks and wish me luck.

I case you were wondering, I am using a ATMEGA32u4 MCU with arduino bootloader and the 4d Systems 4inch touchscreen(might bump up to the 7 inch if this thing grows).

 

Land Rover Manuals

D2 electrical circuits and diagrams may be able to help. Please post updates; I'll be curious to hear how this works!

 

D2's are very easy to add a remote start system to since there is no RFID key chip to bypass... The push to start is easily do-able (electronically speaking) with a few relays and even easier if you are good with micro controllers and arduino (tach-sensing crank time and latching ignition signal come to mind for this). The issue you will have with the PTS is safely bypassing the column lock. If it were me I would be disassembling the column to completely remove the lock.

As for the central locking, the arm and disarm wires are easily accessible in the drivers kick panel. Just a simple (-) trigger. Note that these cannot be used to lock the doors when the car is running. You need to use the wires at the central locking switch in the dash to lock when running. The disarm wire will unlock the doors when the car is running though.

Windows shouldnt be too bad to operate remotely... I believe the front windows are on relays so you should be able to operate them with low current signals. The rear windows are not relayed so you will have to add some relays to be able to control them.

This info is based off of adding remote start and keyless entry to my 03 and 04. Not sure if earlier D2s apply. They *should*. The alarm arms and disarms like factory and I can re-lock the car after disarming it to remote start it using the same lock button on my keyfob.

And heres my .02cents on the PTS having designed a few systems for classic cars.
Definitely remove the column lock. Dont just disable it. God forbid something fails and the lock pops back out locking the column while driving.

I tried the RFID stuff. I couldnt find any reliable 12v system (that wasnt a complete rfid pts "kit") that gives the range of a modern car. You need a uHF passive (ideal) or active HF RFID so that it can be read from more than 12" away. Heres how I got around that lack of "security" to a PTS system. If you use an alarm system in conjunction with the PTS, the alarm will have a ground when armed signal that you can use to disable the PTS. Most of the time you can only disarm that with the alarm keyfob. So as long as the car is locked, no one can start the car, even if they break in. Hot-wiring is now even more difficult since none of the wiring is factory. (do people still hotwire cars??).

I have a viper alarm and a PTS system I designed in my corvette. I can control the windows, door locks and monitor the car right from my phone. I dont even need a key to drive the car as long as I have my phone. The phone is not necessary though.
I have another PTS system in a 67 chevelle and 55 chevy using the viper alarm and an infiniti PTS button. The viper alarm works very well with the infiniti PTS button to keep all of the light-up functions working like factory.

 

I have already yanked out the barrel assembly to include the wheel lock, although I may need to build a solenoid system the locks the wheel for me in the future for inspection purposes. I also already have the MCU hooked up to the ignition and starting the truck, it is controlled via the touch screen.

Thank you for the alarm line info, those are the lines I am really looking into taping at the moment. You you say "a simple (-) trigger" so you mean that the lines need to be pull low?

As far as remote transmission tech I still am on the fence on which standard to use. I would prefer the fob be passive, but I can integrate just about anything into the ATMEGA. As far as security goes right now it is set up that you cannot start the car without a 6 digit PIN. I may end up keeping it that way and just use RFID/uHF to unlock and lock the doors based on range.

As far as tach sensing crank time goes, if I were building this for someone else I would want to do that. But being that I know my truck pretty well, I just put a 1.5 second timer on the start relay.

Thanks for you input!
