How To Reinstate Two Step Unlock? ’06 Toyota Camry, Viper 4x06

I'm really curious Because I've got the drivers door apart to replace a failed actuator, and I want to reinstate the two step unlock like the factory keyless entry did Vehicle is an '06 Camry, no factory security, system installed is a Viper 4x06 remote start and keyless entry I was probing around on the drivers actuator and found two thicker wires They both rest at ground, but if you pulse + to one of them while grounding the other, the doors unlock (two stage) and lock (killing the dome light) just as if you were turning the key in the door barrel The problem is, the 4x06 only has two 500ma negative outputs for lock/unlock I have a 451m door lock relay laying around How would I wire this up? I'd think a "type a" 12+ pulse, but I'm not sure Any advice would be much appreciated Thanks, Mike.

You might be able to get priority unlock working by changing the Viper unlock settings back to single pulse instead of double pulse. If so it would require no changes inside the door. Not certain though so you should try it first. Menu 1, Item 5. change from option 2 back to option 1.Steve G

That didn't do it I suspected such, as the way it's wired now is simulating pressing the power lock button on the door, so it's single stage Anyone have experience wiring two step unlock on Toyotas? It seems like it should be so simple, yet it's difficult I've got two wires on the door lock actuator, they both rest at ground, alternating positive pulse to lock/unlock, but you have to be supplying the other side a ground for it to work

Not sure exactly how to wire the driver only relay but you can program the White/Violet wire to a 2nd unlock output in Menu 2 Item 7 Option 6. Item 7. AUX 1 Output Type (White/Violet wire, 24-pin harness) Option 6. 2nd Unlock: this output will operate as 2nd Unlock and will not activate for remote control commands. Others on here may be able to help you with the exact relay wiring for your car. I think it's called 5 wire and may be elsewhere in the forum if you search.Steve G

This might be the diagram you'd use for the wiring connections using the 451M https://directechs.blob.core.windows.net/techdocs/document11614_0-5045_0.pdf? I think you leave the lock wire where it currently is and just swap the current unlock output from 4x06 to feed the 451M blue wire on 3 pin harness. Then connect the 2nd unlock output White/Violet wire to the blue unlock all wire in the Camry. Hopefully someone else can look this over and see if it looks correct. SteveSteve G
