Hola, estuve investigando más sobre 897A0-2010 y 897A0-2011 y noté que 897A0-2010 es para vehículos con llaves inteligentes y 897A0-2011 es para vehículos sin llaves inteligentes. Lo extraño aquí es que el tuyo es LE y creo que sin llave inteligente y tiene 897A0-2010

 

The following are all the types of keyless entry receiver for the 2014-2019 Corolla.

With Smart Key and with TPMS:

• 897B0-02010

With Smart Key and without TPMS:

• 89740-02160

Without Smart Key and with TPMS (what this post is about):

• 897A0-02010
• 897A0-02011

Without Smart Key and without TPMS:

• 89741-02280

Keyless Entry Components for 2016 Toyota Corolla | Toyota Parts Center

 

...Both receivers use the exact same plug connector and wire harness, so if you have TPMS, then you have the ability to upgrade to factory keyless entry. 897A0-2010 and 897A0-2011 are interchangeable. Beware that these receivers can fail, so if the one you purchased doesn't work, return it and get a different one...

The receiver in my daughters car partially failed - didn't work in cold weather. I could not find the fault.
I tried swapping it with the one from my corolla and it would not work, so I suspect the TPMS/Door open unit has to be paired with the CPU somehow???
Do you know if that is indeed the case???

 

The non-operation during cold weather is indeed one of the failure modes for these receivers. I'm not sure if the remote programming/code is stored in the receiver or in the car's body ECU. I know the factory keyless entry systems work by using the CAN network, but that's the extent of my knowledge.

Before giving up, I would suggest you buy a used receiver from eBay, install it in her car, and attempt to program the remote fobs using Techstream (or have someone else program the remotes for you).

Here is how to program the remote fobs using Techstream (start at 1:45):

 

Thanks for the info, that last section in the video confirms that the CPU is working thru the door lock/TPMS unit to pair the keys.
...but that's where this story ends. She ended up selling it after inheriting a Tesla. The corolla was doing great when sold at 160K miles, just this one issue.

 

Update:
The door control worked but when registering the tpms I now have the following error

 

 

 

The TPMS sensors in the wheels may be dead?

 

The problem with the tpms is that they cannot be programmed with vci mini because they are incompatible. The recipient wants $41.73 to program the tmps in the new module.

 

I am looking into renting a TPMS programming tool to reprogram the sensors myself after Toyota of Greenville quoted me $900 to "diag" and fix my TPMS sensors. I didn't even ask them to look at it. It was in for the fuel pump recall.

 

So I tried this and a remote will lock and unlock the doors but the trunk won't pop with the remote. You can hear a relay in the dash click but the lights don't flash and the trunk stays closed. My car also doesn't emit a beep when locking or unlocking. I turned the volume for the beep all the way up in the setting but it still doesn't do it. I'm now working on figuring out how to resolve these issues. If anyone has advice please share. Thank you.

 

You have to buy the trunk lock and also the wireless buzzer that is located under the left fender. With luck, the wiring should be there. I have not bought it yet, but I did buy the lock for less than 12 dollars and it still works perfectly.

 

You just have to remove the plastic part underneath and it is not necessary to remove it completely, just one or two clicks.

I also recommend buying the buzzer on Aliexpress, eBay and Amazon. It is very expensive and on Aliexpress they send you an original one.

I bought one for approximately 16 dollars.

 

Yeah I got the buzzer off of Amazon for $16. I ordered a trunk latch for $70 but it ended up not working. The motor wouldn't return to the correct position and it would prevent the trunk from latching. I'm looking for one off of a car at the scrap yard or I might just bite the bullet and order one from Toyota using a Corolla LE vin

 

If i was to try to pull all of these parts from a junkyard car, which trim levels would I need to look for? Does it matter? Would the keys from the donor work in my locks after reprogramming? Sorry if this has already been answered

 

Assuming 2014 through 2019 model year Corolla sedans:

• Look for any trim level that isn't the base model. The base model will have a keyhole on the trunk lid and a keyhole on the front passenger side door.
• The keyless entry receiver should be plug-and-play between all models (again, excluding Smart Key/Push Button Start systems).
• The remote fobs themselves should be interchangeable, but the metal part of the key is not. That's tied to the ignition/door lock key cylinders on each individual car.

 

Thanks! One (hopefully final) question:
The trunk latch has been discussed on this thread, but I'm still a little unclear on whether it's specific to the trim level. Mine appears to have power running to it. Am I good to go, or when I find a donor car, should I go ahead and pull its trunk latch?

 

It'd probably be a good idea to grab the trunk latch as well. Again, if it's anything other than a base model, it should have the appropriate electric release solenoid inside it. Toyota uses the same vehicle wiring harness across several trim levels, so yours should already be wired for the electric trunk release.
