Keyless entry & auto-locking door issues

If there was another RF source nearby (Blue tooth, garage door opener, etc..) it could have been "Jamming" reception of your smart key. If you had a bunch or change or keys in your pocket which covered the smart key, it could have blocked the signal, (this may explain why it worked after you took it out of your pocket to check the status light) or something in your pocket could have depressed the lock button on the smart key. Also, there is a 30 sec. delay from lock to unlock which may account for the brief period of time when the smart key did not appear to be working. As to how the driver's door was the only one locked, it could be a wiring issue, a switch problem or a stuck linkage or you may have hit the manual (mechanical) lock control on your way out of the vehicle, which would only lock that door . If this has not been a habitual problem, I think you can eliminate mechanical problems. When you say all the other doors were unlocked, does this include the hatch back? The reason I asked that is because with the default programming, a smartkey entry via the driver's door will only unlock that door; an entry via the passenger door will unlock all 4 doors but not the hatchback; an entry via the hatchback will unlock all doors as well as the hatchback. Please post if this happens again and give as much detail as you can because the more information you provide, the better we are able to assist you. (ie.. did you just wash the car or go through a rain storm? Water intrusion in a door lock switch or an unlock sensor could cause wierd problems)

I believe he was referring to MANUALLY locking the driver door, not by using the electric locks via the switch on the armrest. This is the only way you can lock a single door: by the manual rocker located by each of the doors' handles.
So, you could have somehow accidentally brushed against the inside door handle thus locking that door, which would not set the rest of the car to 'lock' mode. When not in lock mode, SKS is disabled for unlocking. The fob buttons will still lock and unlock the car though, which is what was indicated was done once it was discovered SKS unlock would not work. The only time the remote door lock doesn't work is when the car is powered on.

The delay between allowing unlock and lock via SKS is 3 seconds. So if you lock the car completely, you have to wait 3 seconds before you can unlock it by touching the door handle.

 

I have this happen all the time IF I am carrying the keys, the fob and bluetooth phone in the same pocket. To get it all to work I have to put the fob in my other pocket by itself or move things around in the pocket. My guess is the signal is interupted by the phone because keys and change by themselves do not cause the problem.

I am not talking about the armrest switch. I am talking about the mechanical rocker located next to the inside door handle. You know, the part that moves when you electrically operate the locks? You can move those parts manually too.

Not if you hit it WHILE you were exiting, with the door open. I checked on this, the other doors won't lock along with this manual lock, nor will it unlock as the door closes.
However, if the fob was still in the car, then the door WOULD unlock after attempting to lock it this way.

Also note, I believe you still can exit even if the door is locked. It automatically unlocks that door when you operate the latch from the inside. You'll set off the alarm though if it had time to arm.

 

Actually, my 2006 Prius has locked the door on me too. It's only happened twice in the months I've owned it, but on rare occasion it does like to lock my door for me. :blink: I never thought to check to see if the other doors are unlocked or not, but then usually it wouldn't matter as usually only unlock the driver's door anyway.

But I'm 99.9% certain that I didn't accidentally flip the manual lock. It's actually fairly difficult to (even intentionally) as you open the door. I'm fairly certain it's an electronic issue.

In that it's only happened to me twice in months however, I'm not concerned. I can't say what environmental conditions may have contributed to the behavior as I can't recall what it was doing on the days it locked my doors for me.

 

I don't find it so difficult to operate the manual lever. If the driver door lock is operated electrically, then the other doors would be affected as well.

 

Dr Ed -

Did you get this resolved? I am having the same issue with my 2006 Prius. It also is causing issues with the rear passenger doors as well. Not unique to a single location and ruled out wi-fi and bluetooth interferance. Dealer has had it for two days and is still looking for the cause. Would love to give them their Corolla back and have my Prius with door locks / SKS that works again.

 

Help!

Smartkey and door handle buttons lock and unlock all doors EXCEPT driver's door. Is this a wiring problem?
