02 s430 key won’t turn.
Hey, my cluster died and I have repaired it and now it works. (The car Has been just sitting in a garage for 2 years with dead cluster). After the repair the key won’t turn in the ignition. Can I try to repair the key or will I need to buy it from the dealership? Or can it be other than the key itself. But the key won’t even unlock or lock the car with the remote and I already have changed the batteries in the key

stsrt with a new battery and if that doesn’t work then pull up passenger carpet and remove the metal plate to get to the Main fuses

Incidentally, the batteries in the key operate the RF (Radio Frequency) system to lock/unlock doors and trunk from a distance, and the IR (Infrared) system for locking/unlocking the doors and opening/closing windows and sunroof at close distances.
The batteries have no function in operating the ignition system - that is done by inductive power from the ECS.

I have often charged the battery before testing and still nothing. I also have changed the fuse block under the front passenger carpet with new one. Aaaand still nothing.

I still say its your battery - from sitting so long it’s too weak even when charging it up , but it just won’t hold sufficient charge . If you don’t try a new battery your missing an essential step. If you have aaa they will bring a new battery to try for free if it doesn’t work
After you try a new battery , not a used one , the next step then you’re going to need a matched set of key shifter ecu and ignition switch taken from a donor car
all 4 parts must be from the same donor car as they Are coded only to work together . They sell matched sets on eBay for about $350 or you can get it from a local car being parted out . Make sure the year of car and .ecu is same part number as yours
