I know that many of us drive cars other than Mopars for our dd's. My wife has asked me numerous times to lub the trunk lock. I've done it and it never seemed to help. Today I sent my 7 yr old in to get the key so I could move the car. My wife gave him something to put in the trunk. You can see where this is going can't you. So he comes out and sticks the key in and turns it to the left instead of the right. The trunk doesn't open and the key came out. They boys tell me, but I cannot get the key to budge either way. On top of this I go to pop the trunk from inside and it won't release from there wither. Yeah gotta be kidding right. I sprayed it up with some PB Blaster and tried nothing. I had other things to do so I left it. So, I figure that I've got a junk lock cylinder, but how do you replace that when you cannot get in the trunk. Youtube to the rescue, a guy shows how to manually release the seat backs from the backseat instead of from inside the trunk, but wait the next video is about a stuck trunk. There is a valet mode on Toyota trunks. The lock is stuck in valet mode, not broken. Back to the garage I go. After spraying more PB Blaster in the lock it still won't turn. I grabbed a can of Brake Cleaner spray and I filled the lock full of that. After fidgeting with the lock some more after the brake cleaner it snaps free with a loud thunk. I lubed it up with some PB Blaster and the lock is turning smoother than it ever has in the 5 or 6 years that we have had the car. Two lessons from today's experience. 1) If you turn the trunk key to the left and remove the key on a Toyota you just put it into valet mode which means the inside release will not work. 2) For a really tight moving lock maybe some brake cleaner will remove the gunk that is in the lock so that it will be freed up and move better. It was a desperate move on my part. I hope this helps some one.
