If a new key replacement is made for a 2020 Toyota Corolla, would the old lost key be de-activated ?

    When you lose the house key, should they come and BULLDOZE your house?  If you truly lost the key, it is irrelevant to the finder(unless the finder is you as you check that Jacket you only wear to weddings and funerals... or put on a ledge in the house because you were going to remember that ledge for the key.  But forgot.  For awhile.  Give it a few months.  The key will show up again.  It always does.

    They just cut keys.  They don't care about your life anymore.  It is a matter for the finder of the key to find the car it works in.  That is the challenge so most likely won't happen.  So no, they do not mess around with your door locks either, because when you car gets stolen, you will be back to buy another.

    .........not likely. Those kind of keys, often up to 5 different ones can be programmed to work the car. Ask the dealer service manager if this is true for the 2020 Corolla or not.

    When new or old keys are reprogrammed to the immobilizer in the vehicle all keys need to be reprogrammed at the same time or they won't keep the motor running. The immobilizer will shut off the fuel injectors. Always have a spare key in case you lose one. If you don't you'll have to tow the vehicle to the dealer to have the new key programmed to the vehicle should you lose your only key.

    It is not deactivated.  It will simply NOT work anymore on your car.

    No, there is no possible way they could do that.
