Both of my keys wore out, so I decide to transplant a chip from most worn key into the new body
First I bought a "cavity blank"
Next I got it cut by ACE hardware
Then I opened my key:

The round glass chip is inside of the white housing
Placed chip in silicone tubing and fit into the cavity

Filled with epoxy

And covered the opening with homemade cover


Works good so far. May not last 6 years but who cares...
PS copy and paste experts are pulling their hair out after wasting money on childish key-less entry that sounds like a baby poop monitor when working
