Discovery II Key Remote Not Working

It happens a lot. The lock and unlock buttons on the key remote cave in and stop working.
You can unlock the door manually, so you don't worry about it - until the little rod that joins the key cylinder
with the latch breaks. Then you're stuck. Locked out.
What do you do?
First off, you will need to replace the handle, this will take a few weeks to arrive, and it wont get you in to your Disco. So, Pry the cover off the remote as if you were going to replace the battery. Then carefully pop out the green circuit board. Remove the battery and check it with a volt meter. It should have about 3 volts.
If the battery is OK, put it back in and referring to the diagram, jump across the two solder joints with a piece of flexible wire and the door should unlock. If the doors don't unlock and the flashers only blink, try the other button. I have done this and it works. the neat step is to get two new remotes and have them programmed. Don't go without a spare.
