Keypad Fix Clean and Restore Conductivity to The Carbon on The Keys and The Copper PC Board Pads

Awesome stuff. Make sure you mix really well. Also make sure you really, REALLY clean the rubber membrane you are applying it to with alcohol. I didn't clean it well enough the first time and it came off after it dried. Once I got it to adhere properly it worked like a champ. Brought my thermostat back from the dead, and saved me about a hundred bucks. Recommended.

This product turned out to be more expensive than buying a new remote, so check that first. To use this product correctly, it needs to be mixed extremely well, and then mixed some more. Be sure the area that you will be coating is clean, and slightly roughed up if you can, this will enhance the adhesion of the product to the surface you apply it to - Even with me rubbing it into the rubber button, it often acted like oil and pulled away in an attempt to pool up. I was able to gently spread the watery substance and wick up the excess around the work area with tissue. Leaving it to dry for 24 hours was a no-brainer. I have not pushed on the repaired button very hard for fear of the product peeling off, however it makes perfect contact now and works well. May 24, 2026 update: Product has stood up to extreme use without any degradation.

So far this product has worked great on my cordless phone keypad. The buttons were not working, even after cleaning. So I thought I would try this product. Here is what I did. 1. I cleaned the buttons and the PCB with alcohol to remove any grease and dirt. 2. I used a tooth pick to make sure the conductive paint was thoroughly mixed. This takes a few minutes because the conductive material is pretty thick and gunky until you mix it up. I made sure there was no solid material on the sides or the bottom of the jar. 3. I used a very fine tip paint brush to apply a very thin but complete coverage of the buttons. I had to wear magnifying glasses to see the buttons up close. However, it was fairly easy to apply a thin layer using this approach. 4. I let it dry for 24 hours. 5. I put the cordless phone back together and the phone works great. Now I am not sure how long it will last but even if it lasts a few months, it would be easy to do again. So far I am happy with the process and the results.

There's more in this tub than you'll ever use in your entire life. Very, very little is needed for the job. But when it comes time to use it, you need to be so, very diligent about stirring the heck out of it -- I used a cut-off Q-tip stick (no fluff, just stick) to stir it for a good 10 minutes, slowly churning-away at the thick, coagulated gunk on the walls and bottom, until eventually it turned into a thick paint-like paste... and then stirred some more, for another few minutes, until there were no blobs or gunk and it was all dissolved. Then, I clean the conductive pad on the rubber part of the remote with 99% isopropyl alcohol, let it dry, and... painted the tiniest bit on the pads with the stir stick. I let it dry for about an hour, and then when I could see that it was dry to the touch, I placed the pad on the remote and pressed the button. Finally! The power button worked again, reliably and easily like new. Assuming this fix actually holds up as advertised, this is well worth it - for a remote for a projector that's not seen any aftermarket replacements. Well worth the fiddling.

Cleaned rubber contact points....let dry....mixed compound per instructions....applied super thin coat...allowed to dry 24+ hours. Worked great first day...till all the solution flaked off over next few days. Should have just ordered replacement remote in first place.

This is kinda like conductive paint you dab on let dry, and it works. For a few months (unless I'm doing it wrong), then you take remote apart and do it all over again, every few months. It does work, just not permanently. I wish it was permanent.

Power button on humidifier stopped working. Per instructions, applied Keypad Fix., and waited over night to reassemble the humidifier. Power button now works.

I have already used this product before. This is a conductive paint that you apply to the back of bad keys on rubber keypads (e.g. television remote controls) when the conductive coating on them wears off or is damaged by grease or other contamination. Three things to keep in mind: 1) The new paint will look "flatter" (i.e., not as shiny) as old keys that do not need repair. This is fine. 2) Make sure to gently clean the surfaces with a cotton swab and isopropyl alcohol before applying the conductive paint. 3) Make sure to wipe the inside of the jar lid and top edge of the jar before storing the jar for future use, so you can keep a good seal with the jar lid. UPDATE: Dropping this to four stars. There was one remote control which I tried to repair twice with this and both times the paint came off the rubber pad within 2 weeks. I don't know why it was different on this particular remote control, but it does show to me that it works well when it does work but won't work all the time.
