Hi, Thepart# 5303925437 is the whole lock key assembly. It appears this is the only way it is available and the caos is near $45.00.
I found where www.repairclinic.com has them in stock.
Please let me know if this helps you or if I can assist you further.

Thanks
Vic

just to be sure that your door is sealing properly, put a flashlight into the freezer and turn off all of the lights in the room to see if there are any openings in the seal. Iam suggesting you this coz sometimes a small opening may pass our eyes easily....

if the door is sealing properly......
If this is the type of freezer where the shelves are the evaporator coils, the coolant goes through the shelves(tubing) and the formation of frost is normal and has to be manually defrosted.All the shelves should be as cold asd the top one. The fact that just one has any frost may indicate that it is low on freon. If this is the case you should notice that the freezer doesn't get cold enought just like you said... so check your freon levels.

This could also be because of the thermostat not sensing when the fridge reaches its set temperature and as a result of this the compressor will keep on running and build-up of ice will occur.

Follow the advices in the order prescribed above and you should be set

Would that be the Kenmore 19.6 cu.ft. freezer Model 31205 from about 1981? Kenmore is a Sears product so you might want to check with them if your need service.
