Printer Friendly Forum Posts - Child Safety Door Lock Wire

Man, this website pisses me off sometimes! Half the stuff I post gets lost. Anyway, I'll try again.

It is not at all necessary to find or connecte the Unlock Detection wire, which is sometimes (mistakenly) called the child safety wire, on a '99 Camry.

Under certain conditions, the unlock function of the rocker switch on the door panel becomes disabled. This will happen if you do one of three things:
1. Lock the door using the key in the door.
2. Lock the door using the factory keyless.
3. Open a door, press the power lock button, and then close the door.

It's true that you can get around this feature the hard way-----if you pulse the rocker-switch unlock wire, and the unlock detection wire at the same time, the doors will unlock. But there is a far simpler way.

You'll notice that if you turn the key in the door, you can lock and unlock all the doors this way....the wires that come off the key cylinder are active at all times.

You should simply use the key-cylinder wires, and then diodes and multiple connections are unnecessary.

The necessary wires are at the large orange plug coming out the bottom of the fuse box.

The dark blue/white wire will test by turning the key in either door to the Lock position....pulsing this wire with your alarm will lock all doors.

The dark blue wire tests by turning the key in the passenger door to Unlock...pulsing this wire will unlock all doors at once.

There is another wire there, which tests by turning the key in the DRIVER'S door to the Unlock position.....I'm pretty sure it's GREEN/ red. If the car has factory Toyota keyless, one pulse to this wire will unlock the driver's door only; a second pulse will unlock all doors. If there is no factory keyless, a single pulse will do nothing, and a double pulse will unlock all doors.
