Handbreak auto unlock for civic 2007
Here is another circuit i put together for using handbreak to auto unlock doors since the civic 2007 dxg model (i dont know about other sub models) doesnt do it.
Yes, sure, shutting off the ignition from key will trigger door open, (driver side only), but, when using remote starter on a manual tranny, "ready mode" requires unlocking door manually, or, even still, stopping by to pick up someone or drop someone off without shutting off the car is annoying going to reach for the all door unlock button. anyways </end rant> :)
Now whenever you pull handbreak, the doors all unlock, the built in safety on the civic prevents the unlock button from being depressed for long period. Added to that, I chose a timer module to not only activate the all door unlock but only for a 3 second ground signal, then the module shuts off. neat? this is for anyone who cares for little projects like this ;/
my 2 other projects are auto garage door and auto headlight cut off within a predetermined time, making the switch ineffective unless the key is put back in to reenable the civic wiring. use the search :)
anyways here we go:
for the timer circuit, i used cana-kit CK002 model. You will need an additional 5volt relay as well, i will tell you why.
The CK002 kit, which is assembled by the user, costs like 10$ CAD. For this circuit, i did not use the 9volt battery wire, its capable of 9-12volt and i've used this circuit in car environment many times without issues.
The output of this CK002 PCB for the led and relay is 5volts. So somewhere in that circuit it dropped the voltage, but anyways, luckily 5volt relays exist.
For the 5volt relay, you can use any, just get their diagrams to know which pin is which, or, you can even trace it out manually using an ohm meter to know which pin does what.
I used RDP-115 relays from abra electonics in montreal, as well as the ck002 can be purchased there too.
basically, with about 11 or 12 bucks, you can make your own auto unlock circuit as i did. just trace the door unlock wire on driver boot, for me it was easy, after i had a professional alarm installed, i recently used a tester on the existing 2 wires going to the boot of driver door to find the sweet trigger wire. i also enclosed these 2 chips in a small black box, which can be purchased anywhere, for another 3 bucks or so.
hope someone finds this useful :)
