The 08 exploder has a feature I would like to see a diagram on.
When your key is in the ignition, you can lock all your doors but in a bout one second, all doors unlock by themselves.
Anyone have a diagram on this circuit? Looks like a nice mod to try.
Is that so a thief doesn't have to break a window to steal your car if the keys are in it??? Dunno if the GM has that feature, since it has a door keypad I'll guess not...
My sisters Murano has a "start button"... As long as the key is inside the car(in her purse for ex) it will start... Too technical for me...
Sorry the Ford things sound good for the most part but theres got to be some downside to it but it might be fun project and it would be cool if you got it wired up.
nope GM has this cool thing in the newer HHRs if you car will not start the keys are stuck in the ignition which means if your at barret-jackson and your Grandma left the lights on the car better hope to good you did not leave anything worth something in the car while you go find some jumper cables. it was a rental car and after the company sent someone to jump the car the radio would not work and the car died at the next stop and they guy who helped us just jumped another car right outside and so i stopped him to jump the car again.
Sorry off topic but i did ask the GM guys at the show in the front room why GM would be so smart and make it where you can not lock up your stuff and go look for help.
The car does ding a lot more with the keys in or lights on.
You make a good point though but I like the feature. I stewed on it in my head and thouht I would ask how the wire in the key switch cables out and to what.
The only way i found out it had the feature was when i went to lock the doors upon getting out and they unlocked on thier own preventing me from screwing up.
+1 for FORD and -1 for GM thats good it helped you out
The GM I refered to is my '07
Grand
Marquis...
And no it doesn't have the feature, I checked last night... Has a door keypad, so isn't necessary...
Does it have remote start as well?
My 01 Merc GM with keyless entry key pad.
Will unlock in one second if locked with key in and door open, using the lock button on the door.
Will stay locked if using the button on the key fob.
Looking in the GM EVTM, it's all done with the magic of solid state modules.
Name a electrical function on a newer car that isn't(fuel release door doesn't count)... BTW my '07 GS doesn't have this feature, guess they are cutting costs everywhere... Also has no under hood light...
EDIT... I checked my GM and it's as you say, using the door lock button and door open, it almost immediately unlocks the doors with key in ign... So yes it has the feature Scott is referring to(I was manually locking it) ... IF you shut the door with key in ign, it will not lock on first try using the 7/8-9/0 buttons... Locks normally on second try and stays locked... Will not lock at all using keypad with door open & key in ign(didn't try without key)...
People other than my 72 year old Dad (and others of his ilk) drive GM's? :D
could it really be this simple?
I seriously doubt it, 20yr later you're comparing apples and oranges...
I'd be willing to bet the keyless circuitry today is prob 5x what the '87 is...
Your pop ain't that much my senior... Been tooling around in Grand Marquis' since '93(when I got a used '86 with 45K mi)... Prior I had a Diesel Olds and a '78 3.3 liter V6 Chevy Malibu... The '86 brought me out of the dark ages, as I bought a '87 2.3 Stang a month later and in '94 got the 5.0 Stang(all long gone)...
Wait the wife's 91 year old aunt still has the '86 GM(and lives in a
upstairs apt, hope I'm doing as well physically 33 years from now)...
what i meant was the simplicity of the mod to our cars,, not "could my 08 explorer circuit be this simle. I know darn well that circuit is far more complicated.
However, to mod our cars,, could the above diagram result in the below operation and be such a simple mod? It sure does to me but asking other doctors opinions : )
The key reminder has continuity with the key in.
The added door switch has continuity w/door open.
these above circuits are in series.
The results are:
Door open / Key in=
You open your door and ALL the doors auto unlock on thier own.
You hit the lock button (keys in) and instantly they unlock on thier own incase you lock them while driving to be safe.
Sound correct?
All this for the cost of a generic aftermarket N.O. door jam switch / time / s wire.
I believe i see one flaw,,,,
the key reminder switch is a "one wire" switch. I do not think there is a ground wire meaning the chassis of the switch provides the ground. If thats the case, s this idea. there would be no way to wire out the door switch if this is the case.
anyone know if the key reminder switch is a one or two wire device?
I know my '91 Maxima had it and it worked great, but it also had keypads on both front doors so I never really had to use it.
I figured thats what is meant when the symbol for the ground is flush with the symbol for the switch in the diagram. Thats why i asked, plus since im not in the column often, i recall a single back wire near the key tumbler.
i almost said,, aww ,, then thishiznit me.
This circuit should auto unlock the doors just fine.
locate the wire coming off the key reminder in the column and cut it.
extend both ends up to the new door switch and done.
sounds like a 5 dollar upgrade to me.
the reason for the added door switch is because the existing one passes power through it, the new door switch will supply a ground path.
