Remove need to type ssh key each time (assuming you already have a generated ssh key if not see this)
copy to local file to the remote:
scp ~/.ssh/id_rsa.pub user@example.com:~/.ssh/your_computer.pub
enter password...
then ssh to remote
ssh user@example.com
enter password for the last time
cd ~/.ssh
cat your_computer.pub >> authorized_keys
rm your_computer.pub
exit
done!
One additional note - when you don't want connection to time out see this link.

Update Dec 9 2015:
Once I accidentaly chown of the .ssh folder, that will prvent ssh keys from working. Also these permissions are required:
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys
and optionally chmod 700 ~.

Script I'm using for adding key to remote:
MY_PUB=$(whoami)_$(hostname).pub
echo "Authorizing $1"
scp ~/.ssh/id_rsa.pub $1:~/$MY_PUB
ssh $1 "mkdir -p ~/.ssh; cat ~/$MY_PUB >> ~/.ssh/authorized_keys; rm $MY_PUB;chmod 700 ~/.ssh; chmod 600 ~/.ssh/authorized_keys;"
