Winkhaus Door Lock Repair 

great tips, thanks you...

These gearboxes are cheaply made - which is why it is so easy to bend parts back. I had to replace the gearbox after only five years, and with the gearbox rivetted to the lock strip, this was a messy job.

How do I contact you? I was following your video and messed up the gearbox. Would like to ship it to you for service. Thank you
