maybe they don't see gas keys as wear items or don't believe that their hardware can break.
Carrier gas key staking is a simple task, not requiring much skill, and is a task just about anyone can accomplish at home.
The whole purpose behind carrier gas key staking, is to evenly displace metal from the gas key into the gas key bolts to prevent rotation and loosening under the vibration of firing.
If you have a carrier with a gas key that has never been staked before, the first thing you will want to do is ensure that the gas key bolts are properly secure. For this I often refer folks to the ArmaLite Tech Note regarding gas key torque:

First you’ll want to find a suitable tool to modify into a DIY staking tool. I see lots of suggestions that a chisel will suffice. If a chisel is used with the standard chisel point you will end up cutting into the gas key and bolt heads verses displacing gas key material.
A chisel could be used, if the point is ground flat. Other suggestions I’ve seen mentioned is a flat tip screwdriver. Either of these will work as long as the tools tip is shaped flat and blunt.
After ensuring your gas key is properly secured, place the carrier in a bench vice and adjust the jaws to support the gas key on it’s side.

Remove the carrier and place a shop towel over the vice jaws to protect the carrier during the staking process.
Next, place your DIY staking tool in position on the gas key and strike it with a hammer. The gas key material is not very hard, so it doesn’t take much effort. And if your first staking attempt resulted in a light stake, you can always repeat the process.

Finally, ensure the displaced gas key material does not protrude enough to hinder operation.

Forget red loctite... I would recommend using this + staking...

(Don't plan on servicing the carrier later though... :p)
