Is there a cheap and easy fix for our Honda door lock?

Hi there, the lock on the driver-side door of my Honda Fit seems to be malfunctioning. Is there a cheap and easy way to fix it?

We have a 2007 Honda Fit DX. We do not have keyless entry.

For the past week or so the lock on the driver-side door has been sticky, meaning it is difficult to insert a key into the lock. We really on this lock to unlock all doors of the car for our kids etc.

Is this a common problem? Is there any easy fix?

The car is no longer under warranty.

This happened once before a couple of years ago, and the problem seemed to resolve itself.

I figured it was because of cold weather and rain and dirt getting into the lock. We live in a relatively warm, wet winter climate, although it has been cold recently (no snow or rain) and the roads have been salted.

I use graphite lubricant when this happens (available at any auto parts place). There are also liquid sprays that are available, but in my experience the graphite in a tube works better in the long term. It's cheap and can't hurt to try.

(I use the graphite lubricant when my key is difficult to TURN, but it might help with the insertion issue as well.)

A little WD40 might do the trick. Of course, that is my answer for a lot of things.

All righty, I'll give it graphite lubricant a try and will report back.

If you think it may be dirt, you could try inserting the tube on a can of liquid air and give it a couple of quick squirts.

Don't use WD40 in a lock - it might help in the short term but it is liable to attract dirt and make things worse.

My 2004 Honda Civic is doing the same thing, and just yesterday an insurance adjuster said, "oh, your lock cylinders are going. That's odd." I tried WD40 a while back but
it did nothing.

I just tried using liquid air to clean out the lock, but it did nothing.

I should say that I am able to insert the key most of the way into the lock, but it seems to be "bottoming out" - I can insert the key enough to actually make it unlock the car, as there is something obstructing it at the bottom. I kind of wonder if a graphite lubricant can help with that.

as there is something obstructing it at the bottom.

If it's indeed a small thing, like a stray bit of metal or whatnot...

Get a small straw, like a coffee stirrer. Stick one end in your mouth, the other in the lock. Try to touch the straw to the obstructing object. Suck with your mouth, like a vacuum cleaner.

Hopefully, it'll come out attached to the straw via suction, like a vacuum cleaner trying to suck up a tennis ball. Oh, and try not to inhale anything.

Oh! This just happened with our Fit! We fixed it with graphite, I think.

Try rubbing the key with a soft pencil (home-made graphite).

The graphite solution did not work, and I suspect the lock is broken. I will take the car in to the shop.

My Toyota's trunk lock got stuck like yours (key wouldn't go in) and I fixed it with WD40. I had to blast it a half dozen times between jamming the key deeper and deeper but it eventually saw things my way and has been working well enough since then.
