Subject: TI-81 and TI-82 Key Repair

I just got a TI-81 and TI-82 on eBay, and both have nonworking keys. On the TI-82, the [SIN] key and below don't work, and on the TI-81 the 2, ., and (-) keys don't work.
On both there was battery leakage, corroding some of the exposed key traces away. How do I reconnect the thin wires going from a key contact to the adjacent key? Do I just use a little blob of solder?
Edit: Some of the connections on the TI-81 that go through the PCB are missing from the corrosion, so they're empty holes. Can this be repaired?
