Do the doors themselves lock?

 

They do.

 

I'm pretty sure that's normal.

 

I'm driving my mom's 1st gen Matrix, the lights definitely flash once when locking (twice while unlocking)

If they flash when unlocking all of the electrical connections are there. I'm tempted to say it's the ECU. There's no other pieces of the puzzle afaik... if it has a separate alarm ECU I think those typically just interface with the remote. You have any other weird stuff happening with it?

Curious to see if anyone else knows

 

Make sure all of the doors are shut. The system isn't able to activate if it sees any door not closed completely. This happened to me last night. My son needed the keys to the car. I was told the lights didn't flicker when he locked it. It was a door not closed completely.

 

Make sure all of the doors are shut.

Yeah sometimes we forget to check the simple stuff lol

If the doors are all shut, try opening them after pressing lock... maybe it's not locking at all and one of those door shut mechanisms may be bad.

 

Same Issue

I have been having the same issue with my 2016 Corolla. Have you resolved the problem? If so, may I ask the solution?

Looks like these door lock actuators are becoming bad after years of use. My key fob will not lock and unlock the passengers side. Then yesterday I could not manually unlock the door. The slide button was jammed. I've replaced the handle and lock actuator and it worked fine. Do it yourself because i'm sure it will cost an arm and a leg at the dealer. I got mine at the junkyard in good condition for 35 bucks compared to 300 and the dealer.

 

I just noticed when I lock or unlock my car the yellow lights don't flash as they did before. This just just recent. The beep is so low I depend on the lights to see my car in the dark. Curious thing, the panic button on my smart key makes all the lights flash and the horn go on.

 

Check to see if there's any obstructions in the door jambs. If the door doesn't close completely, the alarm isn't set, but the door will not lock. Check there first.

 

wrong type

 

Toyota Camry 2017
The "Lock/Unlock Feedback Lights" setting is OFF. Make sure to turn it on.

 

how to set (turn them on) thanks

 

Same think just happened to my 2019 Camry, all doors lock yet no lights flash. Settings are set flash and they do flash when the doors are unlocked, just not when they lock...

 

I am getting the same problem bro. IDK how to fix. Do you?

 

Noticed earlier today that the yellow lights don't flash when I lock the car. They do flash, twice, when unlocking. Any ideas on how to fix that?

Same here too

 

Check your doors. The alarm sometimes doesn’t set due to the seat belt or something preventing a lock from engaging.

 

Very helpful. Thank you.

 

Oh my gosh this just happened to me after dropping it off at the Toyota dealer and now it doesn't flash or beep when I lock anyone figure it out

how to do that ?

 

Any reply on this sir? I have the same problem.

 

I solved my problem. Prius gen3 unlocking works like it should, turnin signals twice, but locking did this:

It locked twice and no turning signals. Door locked, but behaviour was weird.

Solution:

I locked all doors manually. Open door, pull locking knob near inner handle and shut door. Rear door lock just shutting door, but front door requires pulling outer handle while shutting. Now when all door were locked manually, I opened them by remote and locking works again like it should: One locking sound and turning signals once.

So if you have that kind problem lock manually. I even tried classic key to lock and unlock, but it wasn't a solution.

 

Hi Priusgen3.
Thanks for sharing this you are a legend. Had this issue on 2018 sahara landcruiser and your solution worked perfectly.
cheers

Nailed it Priusgen3. Worked on 2014 Lexus GX460. My remote start is now working again too.
