Automatic Lock Concept

satwood · 12-03-2007, 10:20 AM

Hi Gang,

As many have mentioned, the Prius does not come with an automatic door lock function. At least, I could not get it on my 2007 model. I purchased the Coastal modification kit and it is programmed to lock the doors when the car reaches 15 mph. However, what I really want is a system that works like my Oldsmobile does. That is, lock all the doors automatically when I put the car in drive, and unlock all the doors when I put the car in park. This is a mode I feel safest with.

I'm pretty sure I could get this to work in combination with the kit I already have from Coastal, by adding some diodes and resistors. The park and drive switches are both momentary so the basic function is already what I need. Has anyone done this or do you have any other similar ideas for this concept?

Thanks in advance
Steve

Are you aware that your Prius' doors will open any time you pull the levers, regardless of whether they're locked? I'm just not sure if auto-locking is that helpful to you, and especially not if you get in a disabling accident...

Move to Australia. I never feel I need my doors locked when I'm driving.

There are instructions on Darell's site at http://www.evnut.com/prius_auto_lock.htm for installing a circuit that will lock the doors automatically at start up.

For the Classic Prius, Coastal sold a circuit that locked the doors when the driver's seatbelt was connected and unlocked them when the seatbelt was disconnected.

i ask the dealership where i got my car and they told me that they can do it.

i automatically lock the doors when i sit down in the car... but that's just habit i guess. no need to unlock before opening the door, as already mentioned.

I bought the Coastal modification that locks the doors automatically. It does that part of the task fine. The problem is that when I get out of the car and then go to get something out of the rear door, then I need to go back and unlock all the doors again. It isn't a huge problem, but a minor annoyance that happens ever day. I was just wondering if someone had already done this unlicking circuit already.

ad78 -- I'll call my dealer. I didn't think of that. I wonder if they have an add-on or if they have a programming capability. Did they tell you?

Thanks much
Steve

I put the same coastal lock into my 07 and it locks the doors as soon as I push the power button! go figure.

@satwood - my saleswoman told me that its a matter of programming. No add-ons.

Some Toyota models do just what you want. My 05 Avalon works that way. Doors all lock when you put the car in drive and all un-lock when you put the car in park.
