The passenger door key-lock on my Corolla is stuck, so the only way I can open that door is to unlock it from the inside. It had been sticking and hard to get it to work using the key in the lock for a while, but now it won’t work at all. I opened the door panel and lubed everything that looked like it needs to be lubed, but that had no effect. The thing you pull to open/lock the door from the inside works a little smoother, and the inside handle that opens the door from the inside works smoother now so that’s something at least. But opening a locked door from the outside with a key remains a no-go.
I tried spraying some WD 40 in there, and putting some WD 40 on the key and trying to unstick it that way, but the key-lock remains stuck in the upright position, won’t budge at all by twisting/jiggling the key.
Anyone here have any luck unsticking a door key-lock ? Heat? Hammer? Ice? Different kind of lube? Cleanser? Swearing? … lol … Or is the only solution to replace the key-lock with a new one?
