I love this thread

I had a spare key that the previous owner said was broken. I was going to cut it open and replace the battery, but wanted to try synchronizing it first. I followed the steps outlined, but still wasn't getting a response.

I then tried the synchronization process using the working key first, and viola. I now have two working keys.

The best part being that the previously non-working key doesn't have the annoying child lock programmed into it.
