Doors won’t lock
 

The touch of the door lock doesn't work, neither does locking it using the buttons on the key fob but it does make and sound when pressing button with the key and the headlights and twilights blink

I was thinking about disabling the locks on my car and just having this angry little gopher that won't attack me but would knaw down to the bone anyone else who tries to rummage through my change in the center console.

Unhook the battery for a few minutes and see if t resets things.

I tried that and it didn’t work

Do the locks open and close normally when you use the key or the buttons in the car? If not then you may have a problem with the harness or a grounded wire, but I don't know. If it is just with the fob then try replacing the battery in the key fob.

Doesn’t work with anything. What ground should I check?

Neither side works electronically using the door card buttons? You can manually lock the doors, but nothing electronically is working on either side, right? Check the fuse. If it is only one side then maybe the harness wiggled loose. Do you have the ability to roll up and down the windows and does the speakers in the doors work (feel and listen carefully)?

What were you doing to the car just prior to the problem occurring? Work your way backwards..

Everything else works on both doors aside from the locks

I bought the car from copart like this

Remove the door card. Make sure the wire/ball is secured into the lock. Check the electrical harness that it is plugged in.

You say that there is a noise when you push the Button. From inside the doors? Both doors? If it is both doors then probably not in the door. If the sound is in the doors then it is trying to work but probably low voltage.

No noises

"it does make and sound when pressing button with the key"


???

Yes it does

yes it makes a noise


no it does not make a noise


yes it makes a noise


I am confused.

So I think he's saying the lights flash and horn beeps but the doors don't actually lock?

OP, do the doors lock when you use the door lock/unlock button in the car?

If not just start tracing the circuit. Start with the fuses.

Or sell the car cheap to me haha

Clearly not an open and shut case.. I don't understand why the OP doesn't go back to the dealer...

It's a salvage title/rebuilt title car. Dealerships will work on it but it won't be under any warranty.

I'm not sure if the car is even fixed yet, he may just be trying to fix this while rebuilding it.

It doesn’t make locking noises with key or from door.
It makes beeping noises when I use the key fob to lock but doesn’t lock

My car is salvage if I go to dealer won’t be under warranty

The body is fixed but not really drive able as of now. Hopefully soon tho

What made it a "salvage"? How bad or good was it?

The front end was smashed and steering wheel and dashboard airbags were deployed. It was ok damage.

Trace. The. Circuit.

You'll find the cause that way.

Okay. Could it be an issue with the ECU? As the airbags were deployed perhaps they triggered something in the brains department ie unlocking the the doors.

The question was, is the noise from in the door?
Is the noise (if there is one) from both doors?
You have established that the fob communicates with the car.
You have not established that the hard wired switch in the door or the key switch will communicate.
Some where between the door and the computer or the computer to the door is a communication problem.
Broken wire, fuse, plug.

No noise from the door I will check the fuse

The car will manually lock, right? You can use the key to unlock and lock the door, and you can manually move the door lock from inside the car to lock the door, right?

Assuming everything is installed correctly (harnesses into their plugs), and they fuse isn't blown, and there is no shorts in the electrical system from the impact, then all I can think of next is this door sensor in yellow. I believe it is an impact sensor. I don't know if it was triggered, and if it was then I don't know if they automatically reset or if they have to be replaced. I also don't know if they trigger something in the circuit that unlocks the doors and/or then cuts the electrical door locks, as a safety feature.

I also thought about it more. There could be a chassis code that is triggered that needs resetting. Again, this could be for safety, so an electrical door switch doesn't force the doors to stay locked.

Use Techstream to see if there is a code that needs resetting.

I have my airbag lights on would that effect it

I honestly don't know, but maybe.

You can buy a Toyota Techstream CD and cable from Ebay for cheap. That's what I did. You can check the code and clear anything.

Like I said, it could be something else. You could call Toyota/Subaru to see if a cool mechanic would let you know if a tripped door sensor needs replacing or could disable the electronic door locks.

It would work for a Subaru as well?

Door locks are handled via the BCM. SRS module is another unit all together. The PW shouldn't work either if the BCM is fried.

Worked on my BRZ.

Ok thank you

No.

Out of 13 or whatever of these salvage 86s now only one had door lock/etc issues and it was a fuse that was blown.

My track FRS doesn't have impact sensors/airbags/etc. Doors lock/unlock fine. All the cars when still wrecked with blown bags and unreset ABS modules, doors lock/unlock fine.

If you want to eliminate the SRS system as a cause simply unplug the SRS module. It's behind and under the HVAC controls. I had a badly reset module before in a car and whenever it was plugged in it made the CANBUS go crazy. Door locks worked but a whole bunch of crap (including the starter 49 out of 50 times) would not. Unplugged it and everything else was fine again. So if the SRS module is causing CANBUS confusion unplugging it will stop it.

We traced that down with Techstream - well sort of. We detected that non of the modules would talk to either techstream and my good OBD tool and just unplugged crap until the problem went away...

Ok I’ll check the fuse

Is it possible it is the actuator
