Toyota Trunk Lid Mysteriously Opens!

I am submitting this tip about Toyota trunk lids. I have owned three Corollas in consistent sequence. My current model is a 2010 Corolla LE.
What really surprised me was being parked somewhere and being away from the vehicle for anywhere from 3 minutes to a few hours, only to discover that when I returned to the vehicle, the trunk lid was wide open!
I was able to find a resolution that I can live with. The "culprit" is the remote key device, which gets activated (unknown to the owner at the time of opening) if the owner and the vehicle are close enough in proximity to open the lid. When the remote is in one's pocket, the trunk lid can easily open and the owner may have no knowledge of it at all. Imagine going shopping and the entire trunk is full of items (groceries, department store items etc) and coming back to your vehicle and finding that everything is GONE! This happened to me at least three or four times a week (Thank God no one took anything..!!!)
The dealer told me to just turn the lock cylinder with the key so that the lock cylinder has the key hole orientated to a "horizontal position". They told me that the lid wouldn't open with the lock cylinder in that position. NOT TRUE!!! This feature only prevents the internal trunk release inside the vehicle from having the ability to open the trunk lid. To my surprise, the lock cylinder can be orientated to the horizontal position and the remote device can STILL open the trunk lid. Since I work at a place where high security is required 24/7, I HAD to come up with a solution that would put a confirmed kill on the problem.
I reached up inside the trunk lid door and disconnected the electrical connector from the automatic lock release. NOW, the trunk lid can ONLY be opened with the key MANUALLY!

I'm sure every Toyota owner has or eventually will face this issue and hopefully, all of the contents of the trunk are still intact. I decided to never give it anymore chances. It is only a very minor inconvenience to use the key to unlock the trunk lid. I can STILL disable the trunk lid release cable by turning the lock cylinder horizontal when I am parked anywhere in public.

I certainly hope this provides everyone with a simple fix!

what is the proper differential oil for a 2010 toyota corolla?

I believe all 2010 Corollas are front wheel drive and what you are searching for is the "transaxle lubricant". Your owners manual should have it listed, or any auto parts store would be able to tell you and sell you the lubricant.

2003 Toyota Corolla LE back seat fold down? how?!

My 05 Corolla trunk would not open. I used a broom handle shoved between the rear seats to activate the emergency release handle on the back of the trunk lid. It took about 2 minutes. When I tapped it just right the lid popped open. This was better the damaging the rear seat by bending it to reach the seat releass mechanism. It turned out that the cable came off in the asembly probably from slamming the lid shut. Once the cable was returned to its location I used needle nose pliers to sqeeze the metal tighter around the cable.

2003 Toyota Corolla LE back seat fold down? how?!

Open the back trunk, look near the top of the trunk, and pull the two black levers. They have a seat folding down symbol. That will release the locks to fold the back seat down.

I need to know where the rear seat release is located inside the trunk of a 2003 toyota Corolla LE

Under the panel between the back window and the trunk lid opening, on the outer edges of the trunk opening.
2 small knobs that look like little cigarette lighters.

if it has any they will be run to near the precut holes rear hat rack but more than likely you will have to run your own wires.pop trunk and look up on the underside by speaker holes. if so it will be two wires run to a plug that is not connected to anything.
