Have Toyota Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.
One possible cause for this is the module that controls the keyless entry key fobs and another is a concern with the door ajar sensors. Can you do electrical diag?
Hello again Chris here,
Do you get the same results from both fobs?
Once unlocked and open with the key your saying the power door lock switch will not unlock the other doors?
When this occurs and you start it, does it crank slow or normal?
Here is your wire diagram https://dl.dropboxusercontent.com/u/90220402/hybrid%20lock.pdf
Does your vehicle have the smart key setup?
Is the vehicle a hybrid?
When inside the vehicle with it running, which door locks will not work from which door switches?
Later is fine.
Based on the other doors not unlocking from the power door lock switch. This would be a failure of the main body ECU. Since the doors will lock this confirms the wiring and lock actuators are fine.
It is the vehicles computer that controls electronic features. You can replace it yourself if you have a dealer equivalent scan tool for programming the replacement.
If you were hoping to be able to address this DIY without the special tools, then unfortunately yes. I wish I had control over that, but I do not.
