Sorry about your problem. The more detail and pictures you can provide to the forum as it relates to the nature of the problem, the easier it will be for other users to help diagnose and solve your locking issue.

I saw this on the forum here so maybe it will help:

Also, a Google Search turned this up too:

If you do not already have one, a technical manual for your RP would be a good idea for troubleshooting and more. Someone on the forums might have one they can send you as a PDF. I have a GR3750 so cannot help. Good luck!
