To effectively use WD40 to fix a stubborn lock, spray a small amount of WD40 into the keyhole and on the key itself. Insert the key into the lock and turn it back and forth a few times to distribute the lubricant. Repeat as needed until the lock operates smoothly.
Try graphite powder
There is a can of graphite spray at your neiborhood do it yourself store , spray it into the lock area and wait, first you can try WD40.
My 406 has been doing the same. My solution is to just spray wd40 into the lock. Works everytime. After a few months it starts again so just keep repeating the process.
spray hinges with wd40
I will assume you mean it will not latch. If the lock hasn't been damaged it's probably just dry. Spray the latch where you can see it in the edge of the door with a spray lubricant such as WD40.
WD40
wd40 might help. I tried WD40, but it didn't solve it. well I'm sorry i can't add to that
It depends on what the indicators are. Usually lubricating the lock with spray lubricant like Triflow or WD40 work. Never use graphite in locks as it tends to get clogged in the springs. If the lock is difficult to turn after this, then there might be a linkage problem which would require removing the door panel and finding the bind or other issue.
A quick squirt of WD40 will fix it.
Things to check, is the release all the way in? Lubricate the lock, WD40 or similar. Adjust the lock up if needed. After you lubricate the lock mechanism, cycle the hood release cable a few times, so that the lubricant penetrates. Continue to lubricate the mechanism at least once every few months to prevent future sticking of the cable.
spray your door latches with wd40.
You don't fix it, you replace the door lock actuator.
