Subject: ignition controlled door locks
Date Posted: July 09, 2007 at 9:07 AM

I have a 2004 nissan wingroad with a viper 5900. I have installed driver priority door locks. Everything works.
I also have ignition controlled door locks. All doors will lock when i start and only the driver door unlocks when i switch off. How can i get all doors to unlock when i switch off without loosing driver priority?

That will be a tough one since you have your unlock wires isolated to achieve the priority unlocking.

You would need to somehow isolate the 'ignition turned off so unlock doors' pulse from the regular 'alarm disarmed' pulse.

You could do this with an off delay timing relay, set for about 2 seconds and triggered off the same ignition feed that the alarm monitors.  This relay would energize as soon as you turned on the ignition and stay energized until the ignition is shut off, and the preset time has passed (2 seconds to go with my example).  You could then use the contacts of this relay to short out your 'unlock output' and your 'priority output' thus making them the same wire only why the ignition is on and for the two seconds after the ignition is turned off.  I can't think of any time you would ever disarm the alarm (unless you have remote start) with the motor running.  If you do have a remote start you could use the status output to trigger another relay that would defeat the off delay timing relay.

Good luck!

Correct me if I'm wrong, but I do believe that your Viper system and my Valet 712T kit are similar with regards to the door locks, right?

In any case, I installed the Valet kit with priority door unlocking and ignition controlled lock/unlock. When I unlock the driver's door and switch on the ignition, the lock signal is sent to all door lock actuators. When I switch off the ignition, only the driver's door will unlock. The same when I unlock all doors: switch on the ignition, all doors lock, switch it off, first the driver's and a second later, the remaining doors unlock.

In other words, the system will only unlock the relevant doors that were initially unlocked.

Is this what you want to achieve?

Yesterday i was driving the vehicle and made numerous stops and discovered that all doors unlock with the ignition just as you described with the driver unlocking first and a second later the other 3 doors. So this confirms what you have said above-because i was trying to figure out how come only the driver will unlock and sometimes all will unlock. Now i know .
I just wish that directed had included all this info in their owners manual.

not that this is directly relevant but i dont prefer driver door priority simply b/c of the fact that when you unlock just the driver door and turn the ignition on it tends to bind the other 3 or 4 doorlock actuators causing them to fail more frequently. i recently bought a suburban and the owner apparently only unlocked the driver door with remote and locked it back constantly with the other doors in locked position. so i had to replace the other 4 door lock actuators but the driver door lock motor works great !

Was the locks you replaced the factory from the car or was it aftermarket ones? How long did it take for them to fail?
I would believe that the locks should be designed to be resistant to this.
I have noticed this problem in my frontier. The vehicle came with central locking . So i installed an aftermarket one on the driver door and notice that when i use the control switch at the driver door with the lock on the closed position , it would bind for a second. The 3 factory locks from the other doors do not bind. I have it working like this for about 4 years now without a problem.

i've worked on 92 gmc's with perfect locks recently and mine is a 99 and had 4 bad factory motors. i called the dealer $85 a piece. so i opted to install aftermarket actuators<which work perfectly>. but like i said i had 4 fail and yet the driver door still works fine. the actual actuator is just a small electric motor with gears so theres no real way to avoid binding

Small electric motor???

Have you ever taken one apart?

I believe they are more like solenoids (electromagnetic)

aftermarket actuators have an electric motor b/c when they go bad you can hear the motor spinning and the gears grinding

How come some vehicles comes with driver priority as factory and they don't burn out?

KP is right they are a solenoid with a worm drive instead of a rod which is why people think there are gears, also some (aftermarket units) are much better than others, e.g. how long they last, pull strength, water resistance tec.

uh k  i checked with a guy at work and yes indeedly doodly solenoids. at dealer cost  i've never seen a reason to open one up for any type of repair no matter how cheap the customer is. besides no matter whats inside it either works or it goes in the trash can. ha ha ha
