Keyless go door handle rebuild repair

3 years ago, I disassembled my keyless go door handle and replaced the buttons and resistors. It's been working great in Oregon with 110f summers, months of rain, and sub freezing temperatures. Would anyone be interested in having their handles repaired? If the first person wants to try this, I'll do it for free, just pay shipping.

How very nice of you Sir!

Maybe you should document this with pictures.
  • problem/solutions
  • disassembly/reassembly procedure
  • bench work to repair

Once I get another door handle to rebuild, I'll document it via video on YouTube so anyone else can follow this process.

Or have me do it.

Yes, I was able to replace both resistors and micro switches.

Unlock is 300ohm and lock is 470ohm.

Did you use metal film resistors ? What state are you in? If I find my old handle, I can send it to you.

Yes, the resistors are metal film resistors.

I would like to use a better microswitch button with more travel/slack. Hopefully someone who knows micro electronics will be able to assist me to improve upon my repair.

can you send me pics of the original switches? So I can see the numbers…Are they SMD switches?
