Default Smart Key System (2006) only working on hatch door!??!

I just got this new Prius, and the SKS unlock all the doors when I touch the hatch door, but when I touch any other door it does not unlock! Also, the light does not come on when I approach the vehicle! This is weird, because it worked just fine when I first got the vehicle. Any ideas? Anyone else see this on their prius?

I seem to remember the manual indicated the system can be programmed for different opening sequences. Possibly yours was inadvertently reprogrammed?

Yeah, there are ways to change what doors you touch and what doors opens when you do -- but this does not seem to be the case -- because in all these options touching the driver's side door would still open at least the driver's side door! I ending up bringing it into the Lia Toyota Dealer of Hadley, MA. They said it might be a quick fix, but I was weary. I was right. At first the guy thought that it was the battery in the SKS remote, but I informed him that didn't add up since it was responding and unlocking the doors when touching the hatch lever (you can see the red light go off on the remote). So, then he thought it might be my USB key on the key chain, but I told him that shouldn't matter since it should not have any elec/mag interference without being plugged into a PC. We removed it to be sure, and that didn't fix a thing.

After 5 hours of prodding, the guys still have no idea what is wrong with it. The only theory is wiring somewhere inside the vehicle. They told me that they are ripping it apart to find the problem. This worries me, since the car is not even a week old! Do you guys have any tips on if this might be a lemon or not? If I remember correctly, Toyota gets a few shots to fix the problem before it is declared a "lemon" in Massachusetts. However, during this time -- I don't have my vehicle It is still at the dealer and I have no idea how long this is going to last. I'd really like to either exchange the vehicle for a new one or get my money back for a new one. It kinda sucks to be in this situation! However, I have enjoyed the Prius very much other than this problem.

Any ideas or suggestions you guys?

I noticed your text in another post:

As a first test, I would simply like to be able to download the binary data, hex edit some simple text string, and upload it back to the Prius.

Did you do any modifications and possibly have the door lock/unlock malfunctions as an unintended consequence?

No -- the minute I pulled into the driveway at my house and got out of the car, I locked all the doors. I moved away from the vhicle, approached it, and unlocked the doors by the SKS sytem. Then, I wanted to show my family the "cool" vehicle-approach-light-on-and-unlock feature that the SKS offers. However, it didn't work! I was pissed. It worked when I was at the dealership and when I immediately returned home, but since then, it does not work anymore. I thought that this might be a common problem with the new model. Apparantly no onw has seen this type of behaviour...

nope, haven't heard one of those yet.

they did give you a rental right? this is a warranty issue.

let us know how it pans out.

btw, it's going to take a lot more than just some wiring issues that make the locks haywire for toyota to cull that car out and give you a new one. my husband had a warranty engine problem- manufacturing specs screwed up and metal chunks in the oil (bad bad bad). he did a complete teardown and rebuild of an engine, on new engine version no less. it was like exploratory surgery for almost 4 weeks, he was the first in the US to rebuild one of those suckers and spent more time than he would have liked describing errors in the repair manual to tech support. the guy got his original truck back, it was not replaced.

that said, MAKE SURE they give your car to a guy with good diagnostic skills. most of the time these guys are Toyota MDTs but not always. wiring problems are a real b**** to sort out and it takes some good skill.

Am I entitled to a free car rental while it is in service? I was unaware of this? How do I get it? Thanks for the suggestions!

if it's a warranty service they should give you a rental. just go ask. unless it's a really tiny dealer and they have no rental cars of their own, then i don't know how it works.

Are you sure you're not pressing the black lock button while opening the front doors? Doing that won't make anything happen.

Yeah, I'm positive that is not the case. Even the Toyota service guys couldn't figure it out At first they told me, "yeah, you sure you're doing it right?" ... "it'll probably take a few minutes", etc. They probably assigned me the dumbest guy too because they thought I was dumb. Turns out, no one has any clue what's going on with it. I'll keep you posted when I find out more tomorrow...
