KEYLESS ENTRY DOOR LOCK TOYOTA DRIVERS
KEYLESS ENTRY DOOR LOCK TOYOTA WINDOWS

If i've locked my car and shut the drivers door, the unlocking wire is turned off (have looked over this and disconnected doors one by one and the problem is still there.) (A)I'm trying to do this as a way to fix the unlocking issue my car currently has. I've seen many poorly installed alarms and keyless sytems that cause all sorts of electrical problems because of shorts. This, however, is the correct way of doing it to avoid any other electrical problems. I can send you the pertinent EWD if that would help. I know this probably sounds more complicated than you initially imagined. Thus when your system wanted to lock the car, your keyless module would send voltage to its lock wire, which would close the relay you installed, which would connect terminal 10 to ground, which would send a signal to the control relay, which finally would provide +12 to terminal 4 and lock the doors.

If that is the case in your device, to work with this system, you would connect the lock wire from your module to a +12 normally open relay (which you've purchased separately), whose switch portion was connected to terminal 10 and ground. Most alarm/keyless module systems simply provide +12 to each of the lead wires to trigger a function. I strongly urge you to use only terminals 10 and 11 to interface with the system. This would create a short and at the very least blow a fuse, or worse, fry the module, which is expensive to replace. You could create a condition where your keyless module is providing +12 V to terminal 4 (to lock the doors) while the door control relay is doing the opposite (grounding terminal 4), for example as part of the 'key reminder system'. This means that if you provide voltage to terminal 3, you are energizing all of the solenoids, as well as providing voltage to the relay itself. Remember that all of the terminals on the door lock solenoids are interconnected, both to all of the doors as well as to the relay. You should NOT (as you suggest) provide voltage directly to 3 or 4.

That is, your inputs should be to terminals 10 (light green) or terminal 11 (green). To get your keyless entry module to work you should be providing the same inputs to the control relay as the door lock switches do. and provide +12 V to either terminal 3 or 4 while grounding the other. The job of the control relay is to take inputs from the door lock switch, key switch, ignition key switch, etc. As I said in my previous post, connecting blue/red to +12 and grounding blue/black will lock the door. Depending on the direction of the current, the electromagnet has opposite polarity and flips the switch in one or the other direction and locks or unlocks the door. It may help you to understand how the door locks work.Įach door has a door-lock solenoid connected to two wires, blue/red (terminal 4) and blue/black (terminal 3). This control relay only controls door locks so you won't affect the windows.Īlso, if you simply connect the blue/red and blue/black to +12, you will likely short out the system.

To answer some of your questions: power windows have nothing to do with this. Do they provide +12V or connect to ground? (3) What do the 'lock' and 'unlock' wires on your keyless entry module do? This is similar to my question 2 above. (2) When you say that you tapped into the light green and green wires, what exactly do you mean? Do you mean that you're supplying them +12V, connecting them to ground, connecting them to a relay, etc.? (1) Why exactly are you trying to bypass the door lock control relay (which is what I think you're calling the 'central locking part of the door control module')? Maybe you can help me by answering a few questions. I'm still a little confused about a few things.
