problem with keyless entry

Hi everyone, Couple days ago I am installed 2 way autostart on my car. Everything works fine except one thing. I cannot to figure out how to set my keyless entry system. My wiring diagram says that I have one wire system (-) and for lock I need to use a negative with 4.7k Ohm Resistor, and for unlock same wire. So what I did. From my remote start module I found two wires based on installation manual (one for unlock and another one for lock). On the wire for lock somewhere in the middle of wire I am solder 4.7K Ohm resistor and merged with only one wire on my car for door lock/unlock based on my wiring diagram from this website (WHITE/ blue wire). Another wire for unlock merged to same WHITE/ blue wire. Now, what's happened. When I press the button on my remote for unlock, works fine, but when I tried to lock - nothing. Can anyone help me with this, please?? Do I need relay maybe? Thanks everyone in advance, and sorry for my bad english. My car: Mazda Protege 1998

Not sure what brand / model remote start you have, but it sounds like it does not have built in

door lock relays.  Its' Lock and Unlock output is probably a 200mA (-) pulse.

Here is a diagram of Bulldog Security's recommendation for the install wiring :

http://www.bulldogsecurity.com/diagrams/extrainfo/diagrams/14301_PROTEGE_MAZDA%20PROTEGE%201%20WIRE%20JBS%20UNITS.pdf  The top diagram would be correct for your application.  The relays are standard 30/40 Amp SPDT ( Bosch ) relays.

And your English is very good. 

Soldering is fun!

sounds like a current issue, what kregs suggested should fix your problem.Ted

Thanks a lot guys. I'll try this on next two days. I hope that will work. I thought that inside of this system has already installed the relay for lock/unlock doors. But maybe that relay is not enough for my car. Remote start system: SPY 2 Two Way LCD Car Alarm (V2)

2 relays, use this diagram:- multiplex_via_relays.bmp Note the 1N4004 diodes, please use them.

Note it bleeding ain't Kreg and I obviously can't read either, I just went to the trouble of doing a diagram for our poster then read your post again!

P.S. I think mine's more easy to read (slightly) and they didn't include the protection diodes, joking aside NEVER do a DEI without.

use a dmm and check those outputs from the unit. if they have built in relays, seeif you have it wired up correctly.Ted

How many lock wires, 2 or 6 and if 6 please list the colours and functions according to alarm manufacturer. This isn't one of these Chinese $20 products is it by any chance, at which point Tedmund and I will sigh in exasperation and as one say "bin it".
