The blue stuff on the screw is most likely Loctite thread locker.
I am a Honda service manager and I’m 100% sure the blue on the screw is
blue Loctite and not corrosion. WD40 is not always needed but can help. A
proper fitting screwdriver is essential. Just simply be patient and go back
and forth slightly and the screw will come out.
This video was very helpful. The battery in my fob was 8 years old, and had
some crud around the screw. I cleaned out the crud, and tried using a cheap
quality jewelers screwdriver but could tell it wouldn’t work. Once I saw
the video got a better quality set of jewelers screwdrivers and a drop of
WD40. I used a #0 Phillips screwdriver, and a CR1616 battery. This was for
my 2005 Accord.
Thanks for the clip, I googled how to deal with the blue locktite and put
my hairdryer on to it and heated it up. I put it on the ground while
heating it as it was too hot to hold while heating it. When it was really
hot I then used the screw driver to undo it, and it worked. Yippeeee…..
I know alot of people have already said it, but thats not corrosion it blue
locktite. They do that so the screw wont loosen up and fall out on you. Not
because the dealer wants you to strip the screw and buy a new key fob.
Believe me its much better than having it fall apart on you one day.
“DW-40” lol
but freezing it ruins the soldering.
I ended up finding this video too late, after stripping my screw head, but
drilled it out and replaced the battery after that. Just wanted to add a
quick comment that I did read somewhere online that if you hold the actual
metal key in boiling water for 1 minute, this should weaken and melt the
loctite glue and you should be able to easily remove the screw. While it is
irritating that Honda used loctite when faced with replacing, I think it
was more for keeping the fob secure.
Thanks, John! I always like to see someone do these little tasks before I
tackle them myself Mine used a Panasonic CR1616… Thanks!
The blue is not corrosion, it’s locktite so the screw doesn’t back out on
its own.
pretty sure its blue lock tight they put on so you strip the screws and
have to go back to the dealer and pay money to get a new one..
I just got this done. At least my Honda Accord 2007 key had some sort of
glue on the screw and heating it seems to be the only way to avoid
stripping it. I only found this out when I went to the service desk at my
local Honda dealer after trying unsuccessfully to unscrew it. They told me
it was almost stripped and applying a little heat did the trick. I bought
the battery for $3.79 + tax at Batteries Plus.
Good video, thanks John!
It’d sure be great if this guy included the battery type in the
description….or at least mentioned it in the video.
what is the battery size/specs?
Still can’t get the d*mn screw out.Managed to strip the screw head on both
of my key fobs. 🙁
John; my screw is too damn frekkin tight to unscrew!!!! it’s starting to
become a STRIPPED head screw!!! Damn you honda for purposely GLUEING the
screw so that WE user can’t unscrew and DIY ourselves. Instead we have to
pay $60 just for Honda to do the job and replace a battery I can do
myself!!! so pissed right now!! I tried WD40 last night and today i tried
to unscrew but no luck!!
Each fob could have their own battery type. When removed then go to your
hardware store or Radio shack and let them present to you the correct
replacement battery.
John, nice job. I put this in my favorites for when my battery needs
replacement. I would imagine the wd40 is the most important step. For I do
not think it is corrosion you see but a locktite substance to keep the
screw in place. The wd40 probably dissolves the locktite.
and i give you John …a BIG THUMBS UP… XD
you can put it in the freezer too. that also works!
Thanks, John! I always like to see someone do these little tasks before I
tackle them myself. I wonder, though, why you didn’t mention what battery
it uses, so that people can watch the video, get the battery (and the
screwdriver if they don’t have one that small) then do the procedure. But
overall, great DIY video!
The blue stuff isn’t corrosion. It’s Locktite. That’s the reason the screw
is hard to get out, the Locktite is a glue that’s supposed to hold the
screw in place.
I followed your instructions to a T, and it worked! Thank you. It cost me
$5.34 for the battery and $8.55 for the small screwdriver set.
THanks for the video! I’m gonna do it right now!
