DIY Installing a $25 Keyless Entry System

This one is a great work around for those of you with worn door lock tumblers

I installed a keyless entry device in the trunk as described above. It worked great. However, I found that I could no longer deadbolt my trunk using the trunk lock. When I deadbolt my trunk, the trunk lock would keep the "lock" wire (green/black) grounded. The central lock controller would then ignore any input from both the "lock" and "unlock" wire coming from the trunk. That means the keyless remote can no longer lock/unlock the doors/trunk. (It still accept inputs from the lock/unlock wires from the doors. Thus central lock still works if you use the key on the doors.)

My solution is to permanently cut the trunk "lock" wire from the trunk lock. The cut is made between the point where I tapped into it and the point where it connects to the trunk lock. (i.e. after the cut, the trunk "lock" wire is then only connected to the output of my keyless entry device). I did not have to cut the "unlock" wire.

I can now deadbolt my trunk and can use my remote to lock and unlock my doors. If my trunk is not deadbolted, then the remote will lock/unlock my the doors as well as the trunk.

Note: only do this if at least one of your doors can be locked/unlocked with the key, that way you know you can still lock/unlock your car with the key when your remote stops working.

I just did this and it works great! The eBay seller will e-mail you back and tell you that you will need an additional part (DLP-P3) for an xtra $12. You do not need it unless you are wiring it up in the drivers footwell so if you are following these directions, don't get the DLP-P3.

What is this "deadbolt", and "double lock" function I have read about.

Sorry for the n00b question:D

double lock is when you are locking the door from the driver side you turn the key to lock and pull it out without turning back up again. so the key hole looks like a minus sign, when you lock it normally it looks like an I, same applies to locking from the trunk.

When double lock that means you can't open the car unless you do it from the driver door, and the same applies if you double lock through the trunk

I'm a little confused still.....I understand where the plug with 4 wires connects to, but where do I connect the plug with only two wires....same wires for the blue and green?

Anyone provide me any insight? I want to get this thing installed!

Oh wow thats cool. I always thought my locks were just messed up and would turn too far sometimes. I had no idea it was actually a designed function, interesting.

Also does anyone have a working link to the zoso page in the first post? The links gone dead and I would like to see what it was all about.

I'm still trying to figure this out!

Not sure if this will help, but I uploaded Zoso's instructions to my web server:

I installed this last year, but I really can't remember what I did with the 2 additional wires. I tried to look at my setup but all my wires are tape wrapped and I really didn't want to cut them all apart.
