Why do some car doors not unlock automatically?

On any DECENT car, if the door is locked and you try to open the door from the inside, it unlocks it for you and lets you out. Yet, certain brands of cars, even today, still don't do this automatically. I noticed it on a brand new Sentra SE-R I test drove 6 months ago. Anyway, whats the deal? Is it just Nissan?

Maybe a feature that has been taken out due to it possibly being a safety issue?

I see it being a safety issue the other way around. You get in a car accident, the electrical system gets messed up, and you can't unlock your door so you are trapped.

Backseat, yeh I'd agree. But upfront, it's nice because you can idiotproof it and make it so that you can't lock yourself out...without really really trying to.

That last comment reminded me of an old Civic I drove, where you could NOT lock the door with the door open. So the only way to lock was to shut the door and lock it from the outside with the key. Now that would drive me nuts.

I would never want that on my car. If it's locked I don't want to snag something on the handle and have the door fling open.

Why is that? Do you like to pull on the handle while driving down the interstate?

I expect the door to open when I try to open it, not for it to be locked shut from the inside.

That is why cars have the child safety locks that keep the inside door handle from opening the door even unlocked. I like the features in BMWs where ther first full unlocks the door and the second pull opens it. Pretty much gotten used to that. Another feature, don't know if it is standard in other vehicles, kick in after an accident. The doors automatically unlock, hazard lights gets turned on, and should the impact be severe enough, a shaped charge severs the battery cable. This prevents shorts from setting spilled gasoline on fire.

The door shouldn't unlock when you pull the handle if the car is in drive anyway. I like the feature. I've gotten very used to it for the front doors -- back doors shouldn't automatically unlock.

Oh yeah, you are correct. I will usually get my car up to about 80 mph, and then I'll open the door and dive out. I get pretty scratched up when I do that, but nothing beats the rush of adrenaline. NOTHING.

My car unlocks like that.

Back passenger seats you pull the handle once to unlock and another time to open the door. For the front doors you just pull the handle once to unlocka nd open. There is a child safety lock so it's not a problem when you have kids in the car.

cant u just unlock the door manually with your hand. im confused by your comment.

With certain cars you can't open the door manually with your hand. They lock goes all the way in and there is no way to get a grip on it. With cars like the VW Phaeton there isn't even a lock you can pull. It's just all electronic.

I think that's also a function of design. On alot of cars the shape of the door dictates how far down the window goes. Goes down all the way on mine tho;)

And about cars where you can't manually lock/unlock. That's complete crap. Thank god my car isn't like that. Electric is nice but if something fails its nice to be able to unlock it manually. Luckily only American cars seem to be like that, at least that I know of.

Well if you think about it it's a security feature. If your lock "knob" pokes out a little like in Honda's etc it is easier to get a wire in there to unlock the door. If it goes all the way down then you can't.

That's how I see it anyway, I don't know if it really improves security but I like the look with disappearing knobs better anyway.

It's a safety thing. Otherwise kids could just open them right up while driving 75mph on the highway. My car is fine the way it is. The doors automatically unlock when the key is turned off.

You never read the manual. ;)

To lock the door without the key, you could pull either handle and then push the lock down (or use the power lock switch).
