I have a 2005 Chrevrolet Impala with a keyless entry remote control.

When I tried to replace the battery, the battery clip came off.

On the bottom of the clip, there are 3 soldering points:
One is square and it's below the clip that holds the battery down
On one "arm" of the clip, there's a metal point that looks like it
went into the circuit board.
On the other "arm" of the clip, there was a matching metal point
but that pont is now missing.

How can I re-solder all three points to the circuit board?
