If there is only one battery in the key fob as is usual with key fobs, perhaps the easiest way to repair it is to unsolder and remove the old battery connectors from the pcb and clean up the board terminals and then solder a [https://www.jameco.com/z/CR2032-LEADS-3V-CR2032-Lithium-Coin-Battery-with-2-Inch-Leads_2223443.html|CR2032 battery with leads - example only] (as long as it fits in the case OK that is)

You can also use any 3V battery (made up of batteries - AA size perhaps connected in a battery holder) and connect it to the key fob to test if it still works or not, before getting a replacement CR2032 battery with leads ;-)

You can also try this [https://www.ebay.com/p/Wire-Lead-Cr2032-Cr2035-Coin-Cell-Button-Battery-Holder-Case-Socket-Q4f4/1882103556|option] and connect it to the key fob to test if it still works or not, before getting a replacement CR2032 battery with leads(I don’t know if it will physically fit into the case but you can use it to test if the key still works ;-)
Unfortunately it is not shown on the board which are the +ve and -ve battery terminal connections on the board, but I’m thinking that there should be reverse battery protection built into the circuit to allow for when people re insert a new battery back in, in the incorrect way and it doesn’t work and they have to reverse the battery to make it work.
